Our certified inspectors walk every major system in your Petersburg home and tell you plainly what they found — then put it in a photo-rich digital report within 24 hours.

Offices, retail, multifamily and warehouses in Petersburg and across Monroe 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

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

Petersburg has roughly 452 housing units and about 92% of them are single-family detached. Homes built in a single stretch tend to wear out in the same places at the same time. That is why when somewhere was built is the first thing worth knowing about it.
The busiest stretch of building here was the years before 1940: 164 homes, about 36% of everything standing today. At 92% single-family it is almost entirely detached houses, so the inspection is nearly always of a whole building rather than one unit inside one.
The median owner-occupied home here is valued at $168,600.
None of this says anything about the specific house you are buying. It is the shortlist a Petersburg home inspector works through in a home of this age, and every item on it gets photographed and written up whichever way it turns out.
Housing figures: US Census Bureau, American Community Survey 2022 five-year estimates.
When Petersburg was built
84% of homes here run on utility gas, and 3 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 use bottled or LP gas.
Local knowledge
Petersburg is a small city that quietly does a few practical things well, and one of them lands squarely in the middle of a property purchase.
The city offers a complimentary notary service during normal office hours, with no appointment necessary. You need photo identification, and the city gives one instruction in capital letters that is worth taking seriously: do not sign your document until you are in person in front of the notary.
That matters because property paperwork frequently needs notarising, and people routinely sign in advance to save time — which defeats the point of the notarisation entirely and means doing it again. A free notary a few minutes away, without an appointment, is a genuinely useful thing to know about while you are buying or selling here.
The second practical thing concerns the water bill. Water and sewer are billed quarterly, but the city makes a point of saying that payments can be made against the bill at any time — you do not have to wait for the quarterly bill to arrive. If a large quarterly sum is awkward, you can pay it down in pieces. Online payment is available for water, sewer and taxes.
The housing is old: about 164 of roughly 452 units predate 1940 and another 94 date from the 1950s, with very little built since 1980. At 92% detached, this is single-family territory almost throughout.

Before you buy
Paperwork
The city’s announcements page carries the notary offer twice, which suggests they have had to repeat it. It is complimentary, available during normal office hours, needs no appointment, and requires photo identification.
The warning that comes with it is the important part. A notary is attesting that they watched you sign. If the document is already signed when you walk in, there is nothing for them to witness, and the notarisation cannot properly be completed. So take the unsigned document and your identification, and sign it there.
We mention it because the period around a property purchase is exactly when this comes up, and because a free service is worth using rather than paying for elsewhere.
The city also publishes property tax information, meeting minutes, its ordinances, a documents and forms section and voting information, so a fair amount of what a new owner needs is in one place.
What the site does not include is a building department page or a named inspector, so we cannot tell you who issues building permits here or who performs the inspections. We are not going to guess — make that a call before you plan any work, and ask for the permit history on the specific address while you are on the line.
A home inspection is not a permit search or a code inspection. What it does is establish what is physically present and in what condition, which is what makes that call specific rather than vague. A buyer’s inspection is the usual starting point.

Utilities
Water and sewer here are billed quarterly, which for a household used to monthly utilities means four larger bills a year rather than twelve smaller ones.
The city’s useful addition is that you need not wait for the bill. Payments can be made against a water and sewer account at any time, so if the quarterly rhythm does not suit your budgeting you can pay in installments of your own choosing. Online payment covers water, sewer and taxes.
That is worth knowing at the point of moving in, when everything else is being paid for at once.
The city publishes water quality reports for 2021 and 2022. Neither copy yielded readable text when we looked, so we cannot tell you what is in them and we are naming them rather than paraphrasing. If water quality matters to your decision, ask the city office for a copy you can actually read.
On the inspection side, what we cover is the building and everything from the house inward: the accessible supply and drain lines, the venting we can see, how fixtures behave when the system is loaded, and the visible condition of any softener or treatment equipment. On housing where a third predates 1940, original galvanized supply where it survives corrodes from the inside and shows as reduced flow and discolored water long before anything leaks.
One local note from the city’s own announcements: it asks residents not to burn leaves and brush in the street, both because it is dangerous and because the city streets have recently been upgraded.

Ordinances
The city publishes a blight ordinance and a separate blight complaint form, so property condition is something it regulates and something residents can raise formally.
Both documents were published in a form that yielded no readable text when we fetched them, so we are not going to describe what the ordinance requires, what counts as blight here, or how a complaint is handled. Guessing at an enforcement standard would be worse than saying nothing.
What we would do as a buyer is ask two questions of the city office. Is there any open blight matter on this address? And what does the ordinance actually require of an owner? Both are quick answers and both are worth having before you commit, because an unresolved matter is something a new owner can inherit.
That is particularly worth doing on a property that has stood empty, or where the exterior has visibly been neglected. On a city where a third of the stock predates 1940, deferred exterior maintenance is not unusual.
What an inspection contributes is the specifics. We report the condition of the roof covering and flashings, the wall materials and any failed coatings, the windows and doors, the porches and steps, and any outbuilding — so you can see exactly what a new owner would be taking on and put a real question to the city rather than a general one.
Commercial building inspections to the CCPIA standard are available where a building is commercial.

The housing
With about 164 units predating 1940 and 94 from the 1950s, and barely anything built since 1980, almost every inspection in Petersburg is an older-house inspection.
Electrical systems have usually been rebuilt in stages by different hands across seventy or eighty years. We look for mixed wiring types meeting in the same box, ungrounded receptacles, undersized or overfilled panels, overfused circuits, and connections made in places that were never intended to be permanent. Original service capacity is frequently the practical limit on what a modern household wants to run.
Plumbing tends to have been renewed in part rather than in whole, so the material transitions where old meets new are where problems concentrate.
Roof coverings will be several generations deep. Heating equipment is typically several replacements from the original, and how well each was fitted and vented matters more than how new the current one looks. Water heaters are usually on their third or fourth.
Foundations from before 1940 are usually stone or early block, and their condition depends far more on how water has been managed around the building than on how they were built. On the 1950s stock the basements are more often poured or block, where the questions are about cracking, past water and what any finishing is hiding.
At 92% detached, garages, sheds and workshops are normal parts of a property here and we inspect them as part of it. Radon testing and mold inspection and testing can be added to any visit.

Drainage
On housing this age, how water is managed around the building is usually the single largest factor in how the foundation has fared, and it is nearly always the cheapest thing to put right.
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 every elevation. On a house eighty years old the original arrangement has usually been altered more than once, and grading that was right at the start has had decades of landscaping and settlement since.
Inside, we look for what past water has left behind: 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 nearly always a story about something that happened once, and it is always worth asking the seller about directly.
A finished lower level deserves a careful look rather than a quick one, because finishing is very often what conceals the evidence of what water has done before.
The city also runs a non-emergency information line to the county sheriff, separate from emergency numbers, for passing along information or asking questions — useful mainly as a reminder to route the right question to the right place.

The buried line
The line running out from the building belongs to the owner, and no visual inspection reaches inside it. In a city where a third of the housing predates 1940, it is very often the oldest untouched component on the whole property.
We will not name a material from a build year. Nothing published establishes what Petersburg lines 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 in there: roots, cracks, displaced joints, bellies or blockages where they exist, and a clear run where they do not. In an old platted city with mature street trees, roots are the common finding and they give no warning until the day the drains back up.
Because sewer is billed inside a combined quarterly charge here, there is no separate signal on a bill that would tell you something is wrong with the line. The first indication is usually the backup itself, which is precisely the argument for looking before you buy.
A camera inspection is added to the same appointment rather than booked separately, and we deliver a full written report with photographs, generally the same day. You can read what our clients say, browse answers to common questions, or get in touch about a specific address in Petersburg.

Reviews
Mitch was great and thorough the our inspection. He provided explanations and suggestions throughout the service. Highly recommend!
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).
What happens
Questions
Yes, and it is free. The city offers a complimentary notary service during normal office hours with no appointment necessary. You need photo identification.
No — and the city says so in capitals. A notary attests that they watched you sign, so if the document is already signed there is nothing to witness. Take it unsigned.
Quarterly. But the city makes a point of saying payments can be made against the bill at any time, so you do not have to meet the quarterly sum in one go. Online payment covers water, sewer and taxes.
We do not know. The city publishes reports for 2021 and 2022 but neither copy yielded readable text when we looked, so ask the office for a legible copy rather than relying on us.
Yes, along with a blight complaint form. Neither document was readable when we fetched it, so we will not describe what it requires. Ask the city whether there is any open matter on an address you are considering.
We could not establish it from published sources — there is no building department page and no named inspector. Ask the city office before planning work.
Seventy to a hundred years. About 164 of roughly 452 units predate 1940 and another 94 date from the 1950s, with very little built since 1980.
Yes. The line under a pre-1940 house is often the oldest thing on the property, and with sewer inside a combined quarterly charge there is no early warning on a bill. A camera inspection goes on the same visit.
