Services
For buyers, sellers, and homeowners keeping an eye on the place they already own. On new construction we also do pre-drywall inspections and 11-month builder’s warranty inspections. Our certified inspectors walk every major system in your St Clair County home and tell you plainly what they found — then put it in a photo-rich digital report within 24 hours.
Following the InterNACHI Standards of Practice:
Included free with every home buyer inspection— and none of them require us to sell your information.
SatisfactionIf you are unhappy with your inspector on the day of the inspection, before you have seen your report, tell us and we will make it right — or you owe us nothing.
30-Day WarrantyA free 30-day Guard home warranty trial, negotiated for you with no obligation. Activate it whenever you are ready.
$100 OffThe buyer’s protection guarantee: if the first home we inspect for you does not make it to the closing table, for any reason, we take $100 off any further home buyer inspection within 30 days of the original.
Optional services at an additional cost — not part of a standard inspection. Tap one to see what it covers.
A camera down the main sewer line, watching its condition from the inside — roots, breaks, bellies and blockages no visual inspection can find. More about sewer scope inspections
The wood-destroying organism report VA buyers are typically asked to provide, on the federal NPMA-33 form. Carried out during the same visit. More about Veterans WDO inspections
Up to five air samples sent to an accredited laboratory, added to the same appointment rather than booked as a second visit. More about mold inspection and testing

Offices, retail, multifamily and warehouses in St Clair County and across St Clair County. Know what condition a building is in before you sign — or stay ahead of problems in the one you already own. Reports in 24 to 72 hours depending on size.
Following the CCPIA commercial standards:
Commonly added to a commercial inspection at additional cost.
Commercial laterals are longer, older and carry more. A camera is the only way to see the condition of the one you are buying. More about sewer scope inspections
Air samples to an accredited laboratory, which matters most in buildings that have sat empty or had a roof or plumbing leak. More about mold inspection and testing

Add either to a St Clair County home or commercial inspection, or book it on its own. We test and we never remediate, so there is nothing to sell you on the back of a result — the number you get is just the number.
Radon measured in house on a professional continuous monitor; mold samples to an accredited laboratory:
The other things worth testing while somebody is already there.
Carried out after remediation on the treated area and the areas next to it, to confirm what was found. More about mold inspection and testing
A damp basement can have several causes, and the buried sewer line is the one a visual inspection cannot check. A scope rules it in or out. More about sewer scope inspections
View a sample reportSt Clair County housing stock
St Clair County has roughly 72,234 housing units and about 79% of them are single-family detached. Housing that went up mostly in one era has mostly one era’s problems — which is genuinely useful to know before you buy, because it tells you what to look at first.
None of this is a prediction about a particular house. It is where a St Clair County home inspector starts looking in a home of this age, and what we photograph and write up either way.
Housing figures: US Census Bureau, American Community Survey 2022 five-year estimates.
When St Clair County was built
75% of homes here run on utility gas, and 616 still heat with oil. If yours is one of them, the tank is the thing to ask about — where it is, and whether it was ever buried. Another 7,278 use bottled or LP gas.
St Clair County commercial property
Between them they employ about 40,045 people, and every one of them is in a building somebody owns, leases or is about to buy. A commercial evaluation is a different standard of practice from a home inspection — we inspect to the CCPIA Standards of Practice — and the scope is agreed before we start, because access and the extent of the shared systems decide what can be covered.
Establishments, not buildings — several can share one address, and a single owner may hold many. It is a measure of how much commercial property is in use across the county, not a count of roofs.
Business figures: US Census Bureau County Business Patterns, 2022.
Commercial work we are asked for most across St Clair County:
Averaged out that is about 13 people per establishment across St Clair County — overwhelmingly small tenant spaces rather than large plants, which is what usually decides how long an evaluation takes and how much of the plant is shared.
Why choose us
Five reasons people here pick us as their St Clair County home inspector.
Family owned since 2009, more than 16,000 inspections completed and over 2,000 five-star reviews across Michigan. We also handle home buyer inspections, commercial building inspections, mold testing and radon testing.
We do not sell mold remediation or radon mitigation, so there is nothing to gain from a result that comes back bad. The number you get is just the number.
Radon, mold, sewer scope and wood-destroying organism inspections go on the same appointment as the home inspection rather than costing you a second morning.
Most people do, and it is the most useful hour of the whole purchase. Ask anything while we are standing in front of it.
InterNACHI and CCPIA certified, with four Certified Master Inspectors and National Home Inspector Examination passes on the team — none of which Michigan requires. The standards we inspect to are published and you can hold the work against them.
Including weekends, because inspection windows sit on closing dates and closing dates do not care what day it is.
Reviews
I recently hired Trademark for a full home inspection on a new purchase, including sewer scope and radon testing. It was a phenomenal experience from beginning to end. Our inspector, Mitch, did a fantastic job explaining all the findings, and the digital report with photos and videos was superb. Would definitely recommend without hesitation.
Salina HamiltonOak Park, MIWe had Mitch inspect our prospective house and he was amazing. He was thorough, patient to answer my questions and provide feedback on what areas he would recommend having a follow up expert and why. The office was responsive and I was able to book multiple services to be done in the same visit (inspection, radon test, sewer scope).
Chris PlaweckiOak Park, MIThis is one of the finest companies I have come across - that means serious customer service and professionalism. Justin was the inspector and he was very thorough yet very kind to answers all the questions that came in my mind during inspection. He took enough time, no rush, and a very detailed inspection was conducted. Extremely competitive pricing and timing from the company. 100% recommend to anyone looking for any kind of property inspection!!
