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 Plymouth Township 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 Plymouth Township and across Wayne 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 Plymouth Township 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.

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 reportPlymouth Township housing stock
Plymouth Township has roughly 12,186 housing units and about 70% 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.
Most of it went up in the 1970s — 3,189 homes, around 26% of the town.
The median owner-occupied home here is valued at $384,800. There are around 738 manufactured and mobile homes in Plymouth Township. Those are a different inspection — the questions are about the frame, the anchoring and the skirting rather than a basement. Around 504 homes sit in two-to-four unit buildings, where a shared roof, a shared wall and sometimes a shared furnace mean the report has to be clear about where one unit stops.
None of this is a prediction about a particular house. It is where a Plymouth Township 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 Plymouth Township was built
91% of homes here run on utility gas, and 27 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 124 use bottled or LP gas.
Local knowledge
Plymouth Township does not require an inspection before a house is sold. What it has instead is better public records than most, and for a buyer that is worth more.
The Township runs a public Online Property Inquiry, and its permit portal advertises the two things a buyer actually wants: the ability to view inspection history and results, and to track permit activity for a property. Before you write an offer, you can find out whether the finished basement, the addition or the new furnace went through the Building Department at all.
The Township is also candid about the limits of its own data, which is unusual and useful. Its disclaimer states that it makes no warranties, expressed or implied, concerning the accuracy, completeness, reliability or suitability of the information. That is the right way to read a permit record: as a starting point rather than proof.
The housing is spread across five decades rather than concentrated in one. Of about 12,186 units, the 1970s contributed the most at 3,189, but the 1960s added 2,018, the 1990s 2,397 and the 1980s 1,518. Around 70% is single-family detached.
Before you buy
The paperwork trail
This is the part of buying a house here that most people skip, and it is genuinely worth an evening.
The Township’s Online Property Inquiry gives you the assessing record for an address. Alongside it, the permit portal is built around scheduling and tracking inspections, viewing inspection history and results, verifying property addressing, and tracking permit activity. The Township notes that permits usually carry at least two inspections, a rough and a final — so a permit that was opened and never finalled is a different thing from one that was.
Two cautions, and the Township supplies the first itself. It makes no warranties as to the accuracy, completeness, reliability or suitability of the data. The second is ours, and we repeat it on every one of these pages: a permit on file does not establish that the work is in good condition today, and nothing on file does not establish that it was done badly. Plenty of sound work predates a record, and plenty of permitted work has aged out since.
That is where a buyer’s inspection does the part paperwork cannot. We look at the thing itself — the roof, structure, foundation, drainage, electrical, heating and cooling, plumbing and the accessible interior — and report what is failing, what is near the end of its service life, and what to plan for. The record tells you what was declared. The inspection tells you what is there.
If you are planning work
If your offer depends on getting work done soon after closing, the Township’s schedule is worth knowing before you write the timeline.
Inspections are run by trade on fixed days. Building inspections run Monday to Friday. Electrical is Tuesday and Thursday. Mechanical is Monday, Wednesday and Friday. Plumbing is Tuesday and Thursday, with separate residential and commercial windows on those days. Inspections must be scheduled by 2pm the day before, and the Township notes that inspections outside normal hours can be requested but carry a fee.
One more detail that catches people out: homeowners cannot pull permits online. The portal is set up for contractors, who link their account to the Township and are issued a PIN; homeowners use the application forms and the Building Department directly.
None of that changes what we report. It changes how quickly you can act on it, which is a different kind of useful.
Water and sewer
The Township’s Department of Public Works gives a good sense of scale: more than 178 miles of water main, 9,500 water services and meters, 1,000 water gate valves, 2,000 fire hydrants, 145 miles of sanitary sewer and over 3,600 sanitary sewer manholes.
The Township also runs a residential cross connection control program and publishes answers to frequently asked questions about lead and copper in water. Those are information and compliance programs, and we are not going to read a finding into either of them.
What an inspection covers is the part of the water story that belongs to the building: accessible grading and how the ground sheds water away from the foundation, gutters and downspouts and where they discharge, foundation conditions, the basement or crawlspace, floor drains and any sump equipment, and the accessible supply and drain plumbing inside. All of it documented as found, with what could not be seen said plainly.
The buried line
A permit history is a good tool and a visual inspection is a better one, and neither sees inside the buried lateral running from the house to the public sanitary sewer.
On a house from the 1970s that pipe has been in the ground fifty years or more, which is enough time for tree roots to find a joint, for ground movement to displace a section, or for a repair to have been made that nobody now remembers. We will not name a material from a build year, because no authoritative source establishes what Plymouth Township laterals are generally made of.
A sewer camera inspection records what is actually inside — roots, cracks, displaced joints, bellies or blockages where they exist, and a clear run where they do not — and it is added to the same visit rather than booked separately.
Alongside it, commercial building inspections follow the CCPIA standard for offices, retail, multifamily and warehouse property, and radon testing or mold inspection and testing can be added to a residential or commercial visit.

Radon in Wayne County
Zone 3 is the lowest of the three EPA categories — the predicted average indoor level across the county is below 2 pCi/L. So Plymouth Township is not where Michigan’s alarming radon numbers are, and we are not going to pretend otherwise. What a zone cannot tell you is anything about one house: 17% of tests actually run in Wayne County still came back at or above the EPA’s 4 pCi/L action level, which is about one in six. A zone is a prediction of an average, and nobody lives in an average.
We place a continuous monitor for 48 hours and read the result on site — no mail-in kit, no lab wait. How radon testing works · Wayne County radon and inspection coverage

Why choose us
Five reasons people here pick us as their Plymouth Township 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
Ora from Trademark did an incredible job with the inspection and sewer scope of the home I am in the process of buying. He was very thorough, explained everything to me from the start, and made it all super easy to understand which definitely helped to put me at ease a bit more. Highly recommend this company!
Mariah HartmanWestland, MIJim was prompt and thorough during the mold testing. Clearly gave us an explanation about mold and testing process he was going to conduct. Testing was followed by a written report. I would recommend everyone use a third party to test mold, independent from the company conducting remediation work. I would hire Trademark again and strongly recommend them.
Alberto PicconeNorthville, MICowboy “Jim” just did Mold Testing in my parents’ basement. He was Professional, explained the what, how and yet of everything to my Senior parents. Our results came back super quick. He even referred us to the resources on the Trademark website for me to use to fix the leaky basement. It’s 1 stop shopping with Trademark.

Questions
Nothing we found says so. Some cities nearby do run a point-of-sale or certificate-of-occupancy inspection, and we are not going to import one that does not exist here. What the Township does offer is a public property inquiry and a permit portal that shows inspection history and results, which is worth using before you make an offer. Confirm the current position with the Building Department rather than relying on any web page, including this one.
No. They are separate governments with separate building departments, and the City sits inside the Township’s boundary. A rule, fee or process that applies on one side of that line does not necessarily apply on the other. Check which one an address actually falls in before relying on anything you have read about either.
The Township’s permit portal is built for it — the feature list includes viewing inspection history and results, verifying property addressing, and tracking permit activity. The Online Property Inquiry covers the assessing record. Note that permits usually have at least two inspections, a rough and a final, so a permit opened and never finalled tells a different story from one that was completed.
No, and the Township says something similar about its own data: it makes no warranties as to the accuracy, completeness, reliability or suitability of the information. Our version is that a permit on file does not establish that work is in good condition today, and nothing on file does not establish that work was done badly. The record tells you what was declared. An inspection tells you what is actually there.
Spread out, which is the useful part. Of about 12,186 housing units, the 1970s contributed the most at 3,189, with 2,397 from the 1990s, 2,018 from the 1960s, 1,518 from the 1980s and 974 from the 1950s. Around 70% is single-family detached. Because no single decade dominates, assumptions about age and construction do not travel across the township — a 1968 ranch and a 1997 colonial are different inspections with different questions.
The Building Department runs inspections by trade on fixed days: building Monday to Friday, electrical Tuesday and Thursday, mechanical Monday, Wednesday and Friday, and plumbing Tuesday and Thursday. Inspections must be scheduled by 2pm the day before, and the Township notes that out-of-hours inspections can be requested for a fee. Homeowners cannot pull permits online — the portal is set up for registered contractors.
A large system: the Department of Public Works reports more than 178 miles of water main, 9,500 water services and meters, 1,000 water gate valves, 2,000 fire hydrants, 145 miles of sanitary sewer and over 3,600 sanitary sewer manholes. It also runs a residential cross connection control program and publishes a lead and copper FAQ. Where the Township’s responsibility for a service line ends and yours begins is a question for the DPW — we did not find that boundary published, and we are not going to invent one.
It is worth considering, because it is the one thing neither the permit record nor a visual inspection can answer. No visual inspection sees inside the buried lateral running from the house to the public sanitary sewer. On a house from the 1970s that pipe has been in the ground fifty years or more. We will not guess a material from a build year — no authoritative source establishes what Plymouth Township laterals are generally made of. Putting a camera down the line documents roots, cracks, displaced joints, bellies or blockages where they exist, and is added to the same appointment.
