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 reportWilliamston housing stock
Williamston has roughly 1,862 housing units and about 54% 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 1990s — 418 homes, around 22% of the town. It is also less detached-house territory than most of the area at 54%, so condominiums, duplexes and small multi-family buildings are a bigger share of what we inspect here — and those bring their own questions about what is yours to maintain and what belongs to the association.
The median owner-occupied home here is valued at $199,600. There are around 222 manufactured and mobile homes in Williamston. Those are a different inspection — the questions are about the frame, the anchoring and the skirting rather than a basement.
None of this is a prediction about a particular house. It is where a Williamston 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 Williamston was built
83% of homes here run on utility gas, and 17 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 49 use bottled or LP gas.
Local knowledge
Williamston is unusual for a small city in one respect that matters a great deal on inspection day: only about 54% of its housing is single-family detached. Close to half of everything here is attached or multi-unit.
That is a much higher share than most communities we cover, and it changes the questions entirely. On an attached or multi-unit property, the building envelope is shared, the roof is usually shared, and the boundary between what an owner maintains and what an association maintains is a document rather than a wall.
The housing also splits sharply by age. There are 359 units predating 1940 — the original town — and 798 built between 1990 and 2009, which is 43% of the city. Very little was built in between, and almost nothing in the 2010s.
So the two most likely properties you will look at here are a pre-war house in the older core, or something from a 1990s or 2000s development. Those need entirely different inspections, and the second one is frequently the attached kind.
One practical note on paperwork: the permits the City publishes are all land-use permits — zoning, fences, signs, rights of way, lot splits and combinations. Construction permits do not appear on that list, so if you want the building, electrical, plumbing or mechanical history of a property, establish with the City where those records are held before you start looking.
Before you buy
Shared buildings
With close to half of Williamston’s housing attached or multi-unit, a good proportion of purchases here involve shared structure. That deserves saying plainly, because buyers often approach a condominium or townhouse inspection as though it were a smaller version of a house inspection, and it is not.
We inspect what is accessible and we are explicit about the boundary. Inside the unit, that means the same thorough treatment as any house: electrical panel and accessible wiring, plumbing fixtures and visible supply and drain lines, heating and cooling equipment and its venting, windows and doors, interior finishes and evidence of past water.
Beyond the unit, we report what we can see and reach of the common structure — the roof covering and its condition where accessible, the exterior envelope, decks and balconies, and any shared mechanical arrangements we are given access to. Where a limit exists, we say so rather than leaving you to assume it was covered.
The questions we cannot answer are the ones the paperwork answers. Which components are the owner’s and which are the association’s. Whether the association has a reserve study and what it says about the roof. Whether there is a special assessment in prospect. Those come from the association documents, and they matter as much as anything we find.
The practical advice is to read both together. An inspection that reports a roof approaching the end of its life means something quite different depending on whether replacing it is your bill alone or a shared one, and whether the money has been set aside.
On attached housing we also pay attention to the party wall and its fire separation where it is visible, sound transmission indicators, and how the units are drained and vented relative to each other — because a neighbor’s problem in a shared building has a way of becoming yours.
Permits
The City’s permits page lists right-of-way permits, zoning permits, fence permits, sign permits, lot split and lot combination applications, rezoning and special land use applications, and zoning board of appeals applications. It also publishes a development fee schedule.
What is not on that list is any building, electrical, plumbing or mechanical permit. We are not going to guess at who administers construction codes here, because the City does not say on the pages we read. But the gap itself is useful information: if you want to know when a furnace was replaced or whether an addition was permitted, asking the City for "the permit history" may not get you what you expect.
Ask the question directly and early: who holds the building and trade permit records for this address? It is a two-minute question that can save a records request going to the wrong place.
The planning and zoning function is, in the City’s own words, a combination of City staff and planning consultants. Staff are available Monday to Friday through the working day, and the City offers pre-application meetings — which is worth taking up if you are buying with plans in mind.
The right-of-way permit is the one most likely to affect an ordinary buyer. Anything in the public right of way — a driveway approach, sidewalk work, a utility connection — falls under it, and on an older street those are exactly the things that get done informally over the years.
A buyer’s inspection is not a permit search and cannot tell you whether a permit was pulled. What it does is tell you what was actually done to a property and how well, so the questions you ask land in the right place. We deliver a full written report with photographs, generally the same day.
The housing
On the 359 units predating 1940, expect the accumulated history of a long-lived building: electrical rebuilt in stages by different hands across eighty years or more, plumbing renewed in part rather than in whole with material transitions at the joins, four or five generations of roof covering, and heating equipment several replacements from the original, sometimes vented through arrangements that have not kept pace.
Foundations of that era are typically stone or early block, and their condition depends far more on how water has been managed around the building than on how it was built. On a town lot with limited space between buildings, that water management is usually the whole story.
The 798 units from the 1990s and 2000s are at a different stage entirely. They are now twenty to thirty-five years old, which is exactly when the first full round of replacements arrives: original roof coverings reaching the end of their service life, water heaters on their second, and furnaces and air conditioning condensers at the point where the next failure means replacement rather than repair.
Windows and exterior doors from that period are usually the original units, and their seals and hardware are where wear shows first. Failed seals in double glazing appear as clouding or deposits between the panes, and we note them individually.
Decks built with those houses need ledger connections, flashing, fasteners and post bases genuinely examined rather than glanced at. Grading that was correct at handover has had decades of landscaping and settlement since, and on a newer house the basement finishing often conceals what that has caused.
Radon testing and mold inspection and testing can be added to any visit, and commercial building inspections to the CCPIA standard are available for commercial property.
Water and trees
The public works department publishes its hydrant flushing dates, along with limb and branch pickup, leaf collection, snow and ice removal and after-hours emergency procedures.
Hydrant flushing is worth knowing about as a new owner, because it produces a symptom people reliably blame on their house. Flushing stirs up sediment that has settled in the mains, and water can run discolored or cloudy for a while afterwards. If you move in during a flushing window and the water looks wrong, check the published dates before you conclude the plumbing is at fault.
The City has also undertaken a tree inventory. We have not read its findings and will not describe them, but the existence of one is a reasonable prompt to look at the trees on and around a property you are buying.
That is squarely within what we report. Limbs overhanging a roof, contact between branches and the covering or gutters, shade keeping a slope permanently damp, debris accumulating in valleys and gutters, and roots at the foundation, the drive or the walks. Those are ordinary findings and mostly straightforward to deal with, but on an established street with mature planting they are common and worth acting on.
On the drainage side generally, we record where the downspouts terminate and whether they carry water clear of the walls, where any sump pump discharges and whether there is a backup arrangement, and how the ground falls away from the building. Inside, we look for the evidence water leaves: staining, efflorescence, mineral deposits, replaced lower wall finishes and corrosion at the base of mechanical equipment.
The buried line
On any property here connected to a public sewer, the line running from the building out to the main belongs to the owner, and no visual inspection reaches inside it.
On one of the 359 houses predating 1940, that pipe may have been in the ground for eighty years or more, under a street whose trees have had exactly that long to mature — which is precisely why a tree inventory and a sewer lateral are related subjects. We will not name a material from a build year, because no authoritative source establishes what Williamston laterals are generally made of, and a guess in a report is worse than no statement at all.
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. On the older core it is among the most useful things you can add, because the lateral is invisible, not covered by a standard inspection, and generally unknown to the seller.
It is worth doing on the 1990s and 2000s properties too, for a different reason: a line laid during that build-out can carry construction debris or a settled section from the day it went in, and nothing about a thirty-year-old house suggests it.
On an attached or multi-unit property, establish who owns the drain run before you assume anything — it may be shared, and that is a question for the association documents rather than for us.
A camera inspection is added to the same appointment rather than booked separately. You can read what our clients say, look through answers to common questions, or get in touch about a specific address in Williamston.

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!!

Questions
Because only about 54% of Williamston’s housing is single-family detached — close to half is attached or multi-unit, which is a much higher share than most communities we cover. On shared buildings the envelope, the roof and the responsibility split all work differently.
Everything inside the unit gets the same thorough treatment as a house, and we report what we can see and reach of the common structure — roof covering where accessible, exterior envelope, decks and balconies, shared mechanical arrangements we are given access to. Where a limit exists, we say so.
Which components are yours and which are the association’s, whether there is a reserve study and what it says about the roof, and whether a special assessment is in prospect. Those come from the association documents, and they matter as much as anything we find.
Ask the City where they are held, and ask early. The permits the City publishes are all land-use permits — zoning, fences, signs, rights of way, lot splits. No building, electrical, plumbing or mechanical permit appears on that list, and we are not going to guess who administers them.
Anything in the public right of way: a driveway approach, sidewalk work, a utility connection. On an older street those are exactly the things that get done informally over the years, so it is worth asking about.
Check the hydrant flushing dates first. Flushing stirs up sediment that has settled in the mains and water can run discolored for a while afterwards. The City publishes the dates, and it is a symptom people reliably blame on their own plumbing.
Worth looking at rather than worrying about. We report limbs overhanging a roof, contact with the covering or gutters, shade keeping a slope damp, debris in valleys and gutters, and roots at the foundation, drive or walks. On an established street with mature planting those are common findings.
On the pre-1940 core, very much so — those laterals have been under tree-lined streets for eighty years or more. On the 1990s and 2000s properties it is worth it for a different reason: construction debris or a settled section from the original build. A camera inspection is added to the same visit.
