Home Inspection Basics
What an inspection is, what it covers, what it costs, and how to pick an inspector.
A home inspection is a non-invasive, visual evaluation of a home's readily accessible systems and components. Tech Inspect performs every complete inspection to the InterNACHI Standards of Practice, covering the roof, exterior, structure and foundation, electrical, plumbing, heating, cooling, attic, insulation, ventilation, fireplace and interior. It is a condition assessment, not a code inspection, a warranty, or a guarantee that nothing will ever fail.

A Tech Inspect complete home inspection evaluates the roof, exterior and grading, structure and foundation, electrical system and panel, plumbing supply and drainage, heating and cooling equipment, water heater, attic, insulation and ventilation, fireplace, doors, windows, and interior rooms, plus built-in appliances such as the dishwasher, range, exhaust fans and garage door operator. Infrared thermal imaging is included with every complete inspection.
Learn more: What a Home Inspection Covers
A home inspection does not cover anything concealed, inaccessible or unsafe to reach, and it is not a code compliance review. It does not include destructive testing, engineering analysis, pest or termite certification, septic pumping, or an appraisal of value. Items such as radon, mold sampling, solar, pool and spa, and well water testing are separate specialty services that can be added to the same visit.

Inspections average 3.5-4 hours on site, but we allow for 5 hours if I need it. This enables us to better serve our clients, time to thoroughly inspect the home and spend time discussing anything we found with our clients.
Tech Inspect prices complete home inspections by square footage, starting at 475 dollars for homes up to 1,500 square feet and rising in steps to 975 dollars for homes up to 5,000 square feet. Homes above 5,000 square feet or with complex configurations are quoted individually. Pricing is calculated from the listing square footage, and there are no hidden fees or contact-form gates to see the rates.

Tech Inspect delivers every inspection report within 24 hours, and roughly 90 percent of reports are delivered at the end of the inspection itself. Fast delivery matters because most Missouri purchase contracts give buyers a 10 to 15 day inspection window, and the report is what you negotiate from. The report is photo-rich and organized so it doubles as a repair-request document.
Missouri does not license home inspectors. There is no statewide regulatory board that issues home inspector licenses, which means anyone in Missouri can legally call themselves a home inspector. Credentials are therefore the only meaningful filter. Tech Inspect Home Services LLC is an InterNACHI Certified Professional Inspector, IAC2 certified for radon and mold, FAA Part 107 certified for drone operation, and Sprk Solar certified.
Learn more: Why Choose Us
Because Missouri does not license inspectors, ask four questions: what certifications do you hold, what standards of practice do you follow, may I attend the inspection, and how fast is the report. Then ask to see a sample report before you book. Look for a real credential such as InterNACHI Certified Professional Inspector, an inspector who welcomes you on site, and report turnaround that fits your contract deadline.
Learn more: Why Choose Us
No. An appraisal estimates a home's market value for the lender and is ordered by the lender. A home inspection evaluates the physical condition of the home and is ordered by and for you. An appraiser may spend under an hour and will not open the electrical panel, walk the roof or enter the crawlspace. The two reports serve different parties and different purposes.
No inspection can find every problem. An inspection is a visual, non-invasive evaluation performed on one day, so defects hidden behind finished surfaces, buried underground, or only visible under certain weather or usage conditions may not be observable. That limitation is exactly why Tech Inspect includes infrared thermal imaging on every complete inspection and includes client protection programs at no cost.

Buying a Home
Timing, contingencies, negotiation, and the findings that actually matter.
An inspection is the only step in the transaction performed entirely on your behalf. The agent, the lender and the appraiser each serve a different interest. For a few hundred dollars you get a documented condition assessment of the largest purchase most people make, in time to renegotiate, request repairs, or walk away. Waiving the inspection means accepting every unknown defect at full price.
Schedule the moment your offer is accepted. Missouri purchase contracts commonly allow a 10 to 15 day inspection window, and that window has to absorb the inspection itself, report review, any specialist referrals such as a structural engineer or sewer scope, contractor estimates, and the repair negotiation. Booking on day one leaves room for all of it. Booking on day eight does not.
Learn more: Schedule Your Inspection
You receive your report within 24 hours, review it with your agent, and decide what to ask the seller for before your inspection contingency expires. Tech Inspect includes a post-inspection conversation to walk through the findings and a recommended contractor list so you can price the items that matter. The report is formatted to be used directly as the basis for a repair request.
Sort findings into three buckets: safety hazards, active or imminent damage, and deferred maintenance. Safety items such as a defective electrical panel, gas venting problems or missing GFCI protection come first. Active water intrusion comes second because it compounds. Cosmetic and end-of-life maintenance items are real but are usually price-negotiation topics rather than deal issues. Call your inspector if a finding's priority is unclear.
Focus on safety hazards, active leaks and water intrusion, structural concerns, and major system components at or past end of life such as the roof, furnace, air conditioner or water heater. Handing a seller a list of forty items including loose doorknobs tends to produce resistance. A short, prioritized request supported by inspection photos and contractor estimates is far more likely to be accepted.
Usually not. A home inspection report on any house, new or old, will contain a long list of observations, and treating all of them as demands weakens your position on the items that actually matter. Prioritize safety, active damage and expensive systems. Many buyers also prefer a credit or price reduction over seller-arranged repairs, because it lets you choose the contractor and control the quality. Either way you should discuss with your realtor the best strategy to negotiate and handle repair requests.
No. There is no pass or fail. An inspection produces a condition report, not a grade. Even a brand new home will have findings. The purpose is to give you an accurate picture of what you are buying and what it will likely cost to own, so you can make an informed decision about price, repairs, or whether to proceed at all.
​
Tech Inspect accepts card payments only, through the link provided when you schedule. Cash and checks are not accepted. Payment must be made in full and the inspection agreement signed before the inspection begins, or the appointment is cancelled. Card processing fees are absorbed by Tech Inspect, so the price you see is the price you pay. The agreement defines what the inspection does and does not cover.

Yes, and Tech Inspect encourages it. Attending lets you ask questions in real time, see the defects in place rather than only in photographs, and learn where the water, gas and electrical shutoffs are before you own the home. Buyers who attend consistently understand their reports better and make faster, more confident decisions inside a tight contract window.
Selling and Pre-Listing
Getting ahead of the buyer's inspector instead of reacting to them.
A pre-listing inspection puts you ahead of the buyer's inspector instead of reacting to them. You find the issues first, decide which to repair and which to disclose, gather your own contractor quotes on your own timeline, and price the home accordingly. The most common way a deal dies is a surprise finding late in the contract period, and a pre-listing inspection removes most of those surprises.
Learn more: Pre-Listing / Move-In Certified
Move-In Certified is the pre-listing version of a complete home inspection. Tech Inspect inspects the home before it goes on the market, and the report is shared with prospective buyers and agents through Fetchreport.com. Sellers use it to market the home as inspected and transparent, to price with confidence, and to reduce post-inspection renegotiation. It is scheduled around your calendar rather than around buyer showings.
Learn more: Pre-Listing / Move-In Certified
Possibly, It helps in two ways. It removes late-stage surprises that cause buyers to renegotiate or walk, and it signals transparency, which attracts more serious buyers. You also control repair costs, because you can get competitive quotes on your own schedule instead of accepting a rushed contractor estimate during a contract deadline. Fewer surprises generally means fewer delays and fewer failed closings.
​
Address safety hazards and anything actively leaking first, because those items scare buyers most and are cited most often in repair requests. Beyond that, weigh cost against the likely negotiation impact. Minor, inexpensive items are usually worth fixing because they shape the buyer's overall impression. Major end-of-life systems are often better handled with a price adjustment than a rushed replacement.
Missouri sellers have disclosure obligations regarding known material defects, and a pre-listing inspection creates knowledge. That is a feature, not a drawback: disclosed and priced-in issues rarely kill deals, while undisclosed issues discovered by the buyer's inspector frequently do. Your real estate agent or attorney should advise you on how to complete your disclosure form for your specific situation.
New Construction
Pre-drywall, final walkthrough, and the 11-month warranty window.
Yes. New does not mean defect-free. Builders work fast, subcontractors rotate between sites, and municipal code inspections verify minimum code compliance rather than build quality. Tech Inspect routinely documents missing nail strike plates, missing window flashing, improperly notched beams, loose joist hangers and disconnected ductwork in new homes. Catching these before closing is far cheaper than discovering them after you own the house.
Learn more: Construction Phase Inspection
A pre-drywall inspection, also called a rough-in or Phase 2 inspection, is performed after framing, electrical wiring, plumbing and HVAC rough-in are complete but before drywall is installed. It is the last opportunity to see the structure, wiring, pipes and ductwork while they are still exposed. Defects found at this stage can often be corrected at no cost, because no demolition is required.
Learn more: Construction Phase Inspection
Schedule it the moment rough-in is complete and before drywall is delivered. That window is often only a few days, and sometimes less. Tell your builder early that you intend to have a pre-drywall inspection so the schedule can accommodate it, and book as soon as your builder confirms rough-in completion. Pre-drywall inspections use the same flat square-footage pricing as a complete home inspection.
Learn more: Construction Phase Inspection
Yes, and this is the single most misunderstood point in new construction. A municipal code inspection verifies minimum legal requirements on a limited checklist, usually in a short visit. It is not a quality review and it is not performed on your behalf. Passing code and being built correctly are different standards, which is why an independent pre-drywall inspection has value even on a permitted, inspected build.
​

Most builder warranties run one year from closing. An 11-month warranty inspection is a complete home inspection performed shortly before that warranty expires, once you have lived in the home long enough for settling, seasonal movement and workmanship issues to reveal themselves. Findings are documented with photos and video so you can submit warranty claims to the builder while repairs are still the builder's responsibility.
Learn more: Complete Home Inspections
No. A builder walkthrough is primarily a punch list of cosmetic and finish items, conducted by the builder, on the builder's schedule, in the builder's interest. A complete home inspection is an independent evaluation of the home's systems to the InterNACHI Standards of Practice, performed for you. Many buyers do both, because they answer different questions.
Your Report and Protection Programs
What you receive, how to read it, and the coverage included at no cost.
The report is a digital document containing photo-documented findings organized by system, with severity indicated so you can separate safety hazards from maintenance items. It includes equipment tags with model and serial numbers for major systems on applicable inspection types, and a recommended contractor list for defects found. It is structured to be used directly as a repair-request and ongoing maintenance plan.
​
Start at the summary, not page one. Read every safety item first, then anything described as active water intrusion or damage, then major system components near end of life. Treat the remainder as a maintenance roadmap for the years ahead rather than a repair demand list. If any finding is unclear, call your inspector before your contingency expires rather than guessing at its severity.
Yes. The report is yours and you decide who sees it. Buyers routinely share it with their agent to build the repair request. Sellers using a pre-listing inspection share their report with buyers and agents through Fetchreport.com. One important exception: do not send a complete home inspection report to your insurance company, because it is not formatted for underwriting and may be misread.
Every qualifying buyer's inspection includes two InterNACHI programs at no additional cost: the Premium InterNACHI Inspection Warranty, administered by Elite Inspection Warranty Co., and the InterNACHI Buy-Back Guarantee. Both apply to primary residences only. Second homes, investment and rental properties, and new construction are not eligible for the warranty. Eligible inspections are registered automatically within seven days, with no paperwork or application required.
Learn more: Client Protection Programs
If Tech Inspect misses a material defect covered under the InterNACHI Standards of Practice, InterNACHI will purchase the home at the original sale price. There is no deductible and no cost to you. Claims must be submitted within 90 days of closing, the home must be your primary residence, it must be listed with a licensed agent, and it must appraise for at least the original sale price.
Learn more: Client Protection Programs
The Premium plan provides up to 3,000 dollars aggregate coverage per client, with up to 2,000 dollars per claim for structure, electrical, sewer lines and mold remediation, and up to 1,150 dollars per claim for HVAC, appliances and primary plumbing. Roof leak coverage runs five years at up to 500 dollars per occurrence on repairs over 250 dollars. The window is 120 days from inspection or 90 days from closing, whichever comes first.

Inspection Technology
Thermal imaging and drones, and what they actually find.
Yes. Infrared thermal imaging is included with every complete home inspection at no additional charge. Many inspectors bill it as an upgrade or do not offer it at all. Tech Inspect treats it as standard equipment because it routinely surfaces problems that a purely visual walkthrough would miss. A standalone, investigation-only thermal visit is available separately for 275 dollars.
Learn more: Home Inspection Pricing
Learn more: Thermal Imaging
Thermal imaging detects temperature differences on surfaces, which can reveal moisture behind finishes, missing or displaced insulation, air leakage at the building envelope, overheating electrical connections at the panel, and certain plumbing leaks. It does not see through walls and it does not confirm the presence of mold. It identifies anomalies worth investigating further, which is exactly its value inside a short contract window.
No. Thermal imaging is completely non-invasive. The camera reads infrared energy radiating from surfaces, so nothing is drilled, cut, opened or probed. That is a large part of why it is useful during a real estate transaction, when you are inspecting a home you do not yet own and destructive testing is not an option.
A drone roof inspection is a standalone aerial evaluation of the roof, delivered with two separate reports: a written inspection report with timestamped photos documenting roof covering, gutters, fascia, vents, flashing, skylights and chimney, and an aerial measurement report with per-section and total roof area. Homeowners use it before filing an insurance claim or calling a roofer. The standalone rate is 150 dollars.
Learn more: Drone Roof Inspections
Yes. A drone is used as an inspection tool during complete home inspections to view the full roof from multiple angles, including steep or high pitches, and the inspector also physically accesses the roof when it is safe to do so. That is different from a standalone Drone Roof Inspection, which is a dedicated service producing its own written report and aerial measurement report.
Learn more: Drone Roof Inspections
An independent inspection gives you timestamped, unbiased documentation of the roof's condition before you contact your insurer or a roofing contractor. It strengthens a legitimate claim, helps you judge whether the damage even exceeds your deductible, and gives you measurement data to check contractor quotes and adjuster estimates against. If no damage is found, you have a clean baseline record for the next storm.

Radon Testing
What radon is, what the numbers mean, and how testing works in a transaction.
Radon is a colorless, odorless, tasteless radioactive gas produced by the natural decay of uranium in soil and rock. It moves up through the ground and enters homes through foundation cracks and other openings, where it can accumulate. Because it cannot be seen, smelled or tasted, testing is the only way to know whether a home has elevated levels. It is the second leading cause of lung cancer in the United States.
Learn more: Radon Testing in Missouri
Any home can have elevated radon, regardless of age, construction type, or whether it has a basement. New, old, drafty and tightly sealed homes have all tested high. A neighbor's low result says nothing about your home, because levels vary house to house based on soil conditions and how the structure interacts with the ground beneath it. Testing is the only way to know.
Learn more: Radon Testing in Missouri
The EPA recommends fixing a home at 4.0 picocuries per liter or higher. Because there is no known safe level of radon exposure, the EPA also recommends considering mitigation between 2 and 4 picocuries per liter. For reference, the average indoor level in American homes is about 1.3 picocuries per liter, and outdoor air averages about 0.4.
Learn more: Radon Testing in Missouri
For real estate transactions Tech Inspect typically performs a short-term test lasting 48 hours, with results reported within 24 hours of device retrieval. Closed-building conditions are required beginning at least 12 hours before the test starts. Including setup and retrieval, plan on roughly three days from placement to result, which is why radon testing should be scheduled at the same time as the inspection.
Learn more: Radon Testing in Missouri
Tech Inspect charges 175 dollars for standalone radon testing and 150 dollars when it is added to a complete home inspection. Larger homes cost slightly more: AARST testing standards require an additional monitor for each tested level exceeding 2,000 square feet, which is priced at 250 dollars standalone or 200 dollars as an add-on. Homes needing three or more monitors are quoted individually.
Learn more: Home Inspection Pricing
Yes. You continue normal daily activities during the test. What matters is maintaining closed-building conditions, meaning windows and exterior doors stay closed except for normal entry and exit, and not disturbing the testing device. Heating and air conditioning systems that recirculate air can run normally. The device is placed at least 20 inches above the floor in a regularly used room.
Learn more: Radon Testing in Missouri
Elevated radon is a fixable problem. Proven radon reduction systems can lower levels by as much as 99 percent, and most homes can be mitigated for roughly the cost of other common home repairs. Tech Inspect explains the result, what it means for your transaction, and provides referrals to qualified radon mitigation professionals who design and install reduction systems.
Learn more: Radon Testing in Missouri
Do-it-yourself kits exist and are reasonable for general homeowner awareness. They are generally not accepted in real estate transactions, because the result depends on documented chain of custody, verified device placement and confirmed closed-building conditions. For a purchase or sale, use a certified professional. Tech Inspect is IAC2 certified and tests to EPA-recommended protocols.

Roofs, Attics, Moisture & Mold
The failure patterns that cause the most expensive surprises in Missouri homes.
The inspector evaluates insulation type, depth and coverage, ventilation intake and exhaust, framing and roof sheathing condition, evidence of past or active water intrusion, improperly terminated bathroom and kitchen exhaust fans, and signs of pest activity. Attics are where ventilation problems announce themselves first, and they are one of the most common locations for findings that surprise buyers.
Attic mold is almost always a ventilation and moisture problem rather than a roof leak. Warm, humid indoor air reaches the attic through ceiling penetrations or bath fans terminating into the attic, then condenses on cold sheathing in winter. Without adequate intake and exhaust ventilation to carry that moisture out, the sheathing stays damp long enough for growth to begin.
​
Not necessarily. Dark or amber discoloration on attic sheathing is frequently attic ambering or similar staining, which is a different phenomenon from active mold growth and is often historical rather than ongoing. Distinguishing the two matters, because the remediation cost differs enormously. Laboratory surface sampling is the way to answer it definitively rather than guessing from a photograph.
​
No. A complete home inspection documents visible conditions consistent with moisture intrusion and microbial growth, but identifying a specific organism requires laboratory analysis. Mold surface sampling is an add-on service priced at 175 dollars alongside a complete home inspection. Tech Inspect is IAC2 certified for mold, and samples are analyzed by an independent laboratory rather than judged visually on site.
Learn more: All Inspection Services
The most common findings are worn or damaged shingles, lifted or improperly sealed flashing at roof penetrations, deteriorated chimney flashing, counter-flashing and mortar, missing kickout flashing where a roof edge meets a wall, damaged or improperly pitched gutters, and rotted fascia. Missing kickout flashing is particularly costly, because it routes roof water directly into the wall assembly where it stays hidden.
Downspouts that discharge next to the foundation are one of the most common root causes of basement and crawlspace moisture, foundation movement and grading erosion in Missouri homes. The fix is inexpensive relative to the damage it prevents. Inspectors flag it consistently because so many expensive foundation and water intrusion findings trace back to water being deposited at the base of the wall.
​
Electrical Plumbing, HVAC & Structure
The named defects buyers search for, and what an inspector can and cannot tell you.
Federal Pacific Stab-Lok panels were installed widely from the 1950s through the early 1980s and have been associated with breakers that may fail to trip under overload. Inspectors flag them as a safety concern and recommend evaluation by a licensed electrician, who will often recommend replacement. Finding one is not a reason to abandon a purchase, but it is a real cost item to price into your negotiation.
Polybutylene is a grey or blue-grey flexible plastic supply piping installed roughly between the late 1970s and mid 1990s. It has a history of failures at fittings and joints, often without warning, and many insurers will not write a policy on a home that still has it. If an inspector identifies it, treat it as a budget and insurability question to resolve before your contingency expires.
​
The most frequent findings are active or past leaks under sinks and at supply connections, corroded or mixed-metal connections, improper drain and vent configurations, water heaters with incorrect flue venting or missing expansion tanks, and outdated supply materials such as polybutylene or galvanized steel. Most are inexpensive to correct individually, but improper gas water heater venting is a safety item that takes priority.
Typical service lives are roughly 15 to 25 years for a furnace, 12 to 18 years for an air conditioner, 8 to 15 years for a tank water heater, and 20 to 30 years for asphalt shingles, all varying with maintenance, quality and climate. An inspector documents equipment age from data plates so you can build a replacement budget rather than being surprised by it.
​
An inspector documents what is visible — crack patterns and widths, displacement, bowing, evidence of prior repair, moisture, and related symptoms such as sticking doors or sloped floors — and determines whether the observations warrant a specialist. Determining structural adequacy and specifying a repair is the role of a licensed structural engineer. When findings support it, the report will recommend that referral explicitly.
​
Not automatically. Repaired foundations are common in Missouri and a properly engineered repair can be a positive. What matters is the paperwork: who performed the work, what method was used, whether an engineer designed or certified it, and whether a transferable warranty exists. Ask the seller for that documentation, and have the inspector evaluate current condition against it.
​
Specialty Inspections
Solar, pool and spa, 4-point insurance, and well water testing.
A 4-point inspection is a limited visual survey of a home's roof, HVAC, electrical and plumbing systems, plus a minor foundation review, formatted specifically for an insurance carrier. Insurers commonly request one when a home reaches a certain age, when a new policy is written, or when a carrier changes. It is a separate service from a complete home inspection and costs 250 dollars.
Learn more: 4-Point Insurance Inspection
No, and confusing them causes real problems. A 4-point report is limited to four systems and is written to be submitted to your insurer. A complete home inspection covers the entire home to the InterNACHI Standards of Practice and is written for you. Do not send a complete home inspection report to an insurance company. If your insurer asks for an inspection, order a 4-point.
Learn more: 4-Point Insurance Inspection
Tech Inspect performs the certified on-site inspection and data collection, and partner Sprk Solar generates a graded A through F certificate. The report covers measured production versus expected output, remaining useful life graded separately for panels and inverter, installation safety and quality, energy storage and net metering status, and ownership structure. It costs 300 dollars standalone or 250 dollars added to a home inspection.
Learn more: Solar System Inspection
Ownership structure changes the math completely. Owned or loan-financed systems can add value, while a lease or power purchase agreement typically transfers an ongoing payment obligation to you and may require lender approval. A solar inspection confirms both whether the system is actually producing and how it is owned, before you close rather than after.
Learn more: Solar System Inspection
A pool and spa inspection evaluates the visible and accessible pool and spa equipment and structure, including pump, filter and associated electrical components, along with safety-related conditions. It is a separate service because pools and spas are outside the scope of the InterNACHI Standards of Practice for a home inspection. It costs 250 dollars standalone or 200 dollars added to a home inspection.
Learn more: Home Inspection Pricing
Buyers using FHA or VA financing on a property served by a private well are generally required by the lender to provide a satisfactory water test before closing. Tech Inspect charges 250 dollars standalone or 215 dollars as an add-on. Because laboratory turnaround consumes part of your contract timeline, schedule well water testing with the inspection rather than after the report arrives.

Radon is present in all 50 states, and elevated results occur throughout eastern Missouri, including St. Charles, Warren, Franklin and Lincoln counties. Because levels depend on soil conditions and the individual structure, county-level generalizations are not a substitute for testing a specific address. The only reliable answer for any particular home is a professional short-term test.
Learn more: Radon Testing in Missouri
Homes built during the rapid growth of the last two decades commonly show grading and downspout discharge problems near the foundation, attic ventilation and insulation shortfalls, incomplete or missing flashing details at roof-to-wall transitions, and HVAC ductwork issues in unconditioned spaces. These are workmanship and detail items rather than structural failures, and they are exactly what thermal imaging and a drone roof view are useful for finding.
​
​
Older housing stock brings a different set of questions: the age and material of the electrical service and branch wiring, outdated plumbing supply materials, foundation and basement moisture management, roof and chimney flashing condition, and the age of heating and cooling equipment. Older homes are frequently excellent purchases. The point of the inspection is to price what you are taking on accurately.
Learn more: Home Inspection in Franklin County
Yes, and rural properties in Warren, Franklin and Lincoln counties frequently have both. FHA and VA well water testing is available as an add-on service. Septic system evaluation and pumping are performed by a septic contractor rather than a home inspector, and the inspection report will identify when a specialist evaluation is recommended so you can schedule it inside your contract window.
