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

Marine City has roughly 2,225 housing units and about 77% of them are single-family detached. The year a house went up decides more about what an inspection turns up than almost anything else about it, which is why it is where we start rather than where we finish.
More of it dates from the years before 1940 than from any other decade — 1,007 homes, roughly 45% of the town.
The median owner-occupied home here is valued at $139,900.
This is not a forecast for any one address. It is where a Marine City home inspector starts in a home of this age — and whatever we actually find, it goes in the report with photographs.

When Marine City was built
89% of homes here run on utility gas. Another 48 use bottled or LP gas.
Local knowledge
Marine City is old. About 1,007 of its roughly 2,225 housing units — 45% — were built before 1940, and only 44 have been added since 2000. Nearly half the city predates the Second World War, which is a higher share than almost anywhere we work.
On housing like that, the single most useful thing a buyer can establish is which work has been done properly and which has simply been done. And Marine City makes that unusually answerable, because it asks a great deal of anyone pulling a permit.
Every permit application here has to arrive with a contractor’s license, a certificate of liability insurance, a copy of workers’ compensation insurance where applicable, the builder’s driving license or a company affidavit of authorization, and a current contractor registration on file with the City.
That is a real bar, and it cuts both ways for a buyer. Work that was permitted here was done by a licensed, insured, registered contractor — which is genuine assurance. Work that was not permitted was done by somebody who did not clear that bar.
So on a house with eighty-five years of accumulated alterations, the question worth asking the City is simply: what is on file? The answer tells you which parts of the building have documented, insured work behind them and which parts you are taking on trust.

Before you buy
Permits
The building and code enforcement department issues permits for pools, electrical, mechanical and plumbing work, fences, decks, accessory structures and sheds, signs, curb cuts, water and sewer taps, parking storage and zoning compliance. Applications can be made online, and conceptual review meetings can be arranged in advance.
The documentation requirement is the part worth understanding. Requiring a license, liability insurance, workers’ compensation, identification and a current registration before a permit is issued is a higher bar than most municipalities set, and it changes what a permit record means.
In a city where a permit is easy to get, its absence tells you little. In a city where a permit requires a documented, insured contractor, its absence tells you the work was done another way. That is not automatically a problem — plenty of unpermitted work is perfectly sound — but it is unverified, and on an eighty-five-year-old house it is worth knowing which category each part of the building falls into.
The building official keeps a defined window, available Tuesday afternoons and Thursday mornings, while City Hall itself is open through the week. If you want a records question answered inside a contingency period, aim for those windows and start early.
The City also publishes a fee schedule, maintains a code compliance complaint process, and has separate housing and dangerous building boards of appeal. We have not read what either board governs and will not describe it — but their existence tells you the City has formal machinery for building condition, which is worth knowing about before rather than after.
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 and how well, so the records request you make is a targeted one. We deliver a full written report with photographs, generally the same day.

The housing
A city that is 45% pre-1940 and has added 44 houses since 2000 presents a particular kind of inspection. Nothing here is new. Everything has been worked on. The useful question is never whether a system has been updated but how, when and by whom.
Electrical comes first and matters most. A house from this era was wired for a fraction of today’s demand, and every one has had attention since — but there is a wide gulf between a genuine rewire and a newer panel fitted in front of original distribution, and eighty-five years of circuits added in stages by different hands is the norm rather than the exception. We report what the panel actually contains, how the accessible wiring is arranged, and where work appears to have been added piecemeal.
Plumbing follows the same pattern: renewed in part rather than in whole, leaving transitions between materials at the joins, and those transitions are where problems concentrate. A house described as having had the plumbing done usually means part of it.
Roofs on this stock are on a fourth or fifth covering. Heating equipment is several generations from the original, and a newer high-efficiency appliance fitted into an older chimney or vent arrangement is a common and specific thing we check. Insulation and ventilation reflect the standards of a very different era, which usually means a real and worthwhile improvement is still available in the attic.
Foundations of this period are typically stone or early block. Their condition depends far more on how water has been managed around the building across eighty-five years than on how they were originally built, and on an in-town lot with limited space between buildings that water management is usually the whole story.
About 23% of units here are attached or multi-unit rather than detached, which brings its own questions: shared walls and roofs, what an association covers against what an owner does, and whether the envelope has been maintained consistently across the whole structure.
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 drainage
The City publishes its ordinances through an online code library and posts utility notices as they arise, which is worth checking when you are new to an address.
What we report on is the part of the water picture a homeowner controls. We record where the downspouts terminate and whether they carry water clear of the walls or drop it at the foundation, where any sump pump discharges and whether there is a backup arrangement, and how the ground falls away from the building.
On a house that has stood since before 1940, that fall is almost never what the builder intended. Eighty-five years of added paths, raised beds, new drives, landscaping and settled ground change how water moves around a foundation, and the evidence of what that has caused turns up in the basement rather than in the garden.
So inside we look for staining and tide lines on foundation walls, efflorescence and mineral deposits, replaced lower wall finishes, and corrosion at the base of mechanical equipment. Equipment raised up on blocks is usually a story about something that happened once, and it is always worth asking about.
Most of what we find on the drainage side is straightforward to correct and inexpensive relative to what it prevents. It is the difference between a dry basement and a recurring problem, and far better known before you own the house than after.

Outdoor structures
On a city of old houses on established lots, outdoor structures accumulate. Decks, fences, sheds and accessory buildings all require permits here, which means a good deal of what you can see from the street should have a record behind it.
Decks get particular attention from us, because deck failures are among the few structural failures that hurt people, and they almost always happen at the ledger connection to the house. We check how the ledger is attached, whether it is flashed, and whether the fasteners are the right kind and still sound, along with post bases and their bearing, beam and joist connections, guard height and infill spacing, and stair rise, run and handrails.
On a pre-1940 house, a deck is by definition an addition, and how it was attached to eighty-five-year-old framing is the question. Where a deck looks recent and nothing in the permit record explains it, that is worth raising.
On sheds and accessory structures we report visible condition, siting, and any electrical supply run to them. On pools we report the condition and configuration of barriers, gates and latches, and the electrical arrangements serving pool equipment, which is a common place to find informal work. A full pool inspection is separate specialist work.
We do not survey boundaries and we do not assess zoning compliance. What we give you is the physical condition, so you know which structures are sound and which need a question putting to the City.

The buried line
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 1,007 houses here predating 1940 — and that is nearly half of them — that pipe may have been in the ground for the better part of a century, under a street whose trees have had exactly that long to mature. We will not name a material from a build year, because no authoritative source establishes what Marine City 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 a city with housing this old and this little new stock, 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 noting that the City issues permits for water and sewer taps, so a connection that has been replaced or renewed may well have a record behind it. That is a good question to ask alongside the camera.
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 Marine City.

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.
We 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).
This 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!!
What happens
Questions
A full contractor package: a contractor’s license, a certificate of liability insurance, workers’ compensation insurance where applicable, the builder’s driving license or a company affidavit of authorization, and a current contractor registration on file with the City.
Because it changes what the permit record means. Where a permit is easy to get, its absence tells you little. Here, a permit means a licensed, insured, registered contractor did the work — so its absence tells you the work was done another way, and is unverified.
Very. About 1,007 of roughly 2,225 units — 45% — predate 1940, and only 44 have been added since 2000. Nearly half the city is pre-war, which is a higher share than almost anywhere we work.
The electrical, and what "upgraded" actually means. A genuine rewire is a very different proposition from a newer panel with eighty-five-year-old distribution behind it. After that: partial plumbing renewals and their material transitions, four or five roof coverings, and heating equipment fitted into older venting.
Tuesday afternoons and Thursday mornings, while City Hall itself is open through the week. If you want a records question answered inside a contingency period, aim for those windows and start early.
Yes, along with fences, accessory structures, pools, signs, curb cuts and water and sewer taps. That means a good deal of what you can see from the street should have a record behind it.
Because deck failures are among the few structural failures that hurt people, and they almost always happen at the ledger connection to the house. On a pre-1940 house a deck is by definition an addition, and how it was fixed to eighty-five-year-old framing is the question.
Yes, more than in most places. With nearly half the housing predating 1940 and almost no new stock, most laterals have been under tree-lined streets for close to a century. A camera inspection records the actual condition and is added to the same visit.
