Add either to a LaSalle 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 reportLaSalle housing stock
LaSalle has roughly 1,887 housing units and about 97% 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 1950s: 353 homes, about 19% of everything standing today. At 97% 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 $218,400. 86% are owner-occupied, which is high even for this area.
None of this says anything about the specific house you are buying. It is the shortlist a LaSalle 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 LaSalle was built
76% of homes here run on utility gas, and 19 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 271 use bottled or LP gas.
Local knowledge
LaSalle Township does not run its own utilities, and that shapes how you go about buying here more than anything else about the place.
Its own list of useful contacts tells the story. Water service comes from a separate water provider. Drainage and flood management sit with the county drain commission. Septic systems, wells and soil conditions are the county environmental health department. Roads and roadside drainage are the county road commission. Rubbish collection is by private haulers.
So the township handles assessing, zoning, building permits and the cemetery — and almost everything else that touches a property physically belongs to somebody else.
For a buyer that means due diligence here is a set of separate phone calls rather than one. It is not difficult, but it is easy to assume the township can answer a question about your water, your drain or your septic system, and it generally cannot.
The one thing to get straight first is which water arrangement a property has. The township points to both a water provider and the county environmental health department for wells, so both exist here. Confirm it in writing for the specific address.
The housing is spread evenly across the decades — roughly 300 units each from before 1940, the 1950s, the 1970s and the 1990s — and 97% of it is detached houses.
Before you buy
Who to ask
The township’s useful links page is genuinely one of the more valuable pages on its site, because it is effectively a map of who is responsible for what.
The county drain commission is the one buyers most often overlook. On flat, low-lying ground in this part of the county, county drains are the reason land is usable at all, and they come with their own maintenance regime and their own assessments. If a property adjoins or is served by a county drain, that is a question worth asking before closing rather than after — both about condition and about cost.
The county environmental health department covers wells, septic systems and soil conditions. On a property with either a well or a septic system, that is where the specialist work is arranged, and it should be arranged early because it takes its own time.
What a home inspection contributes is the physical evidence on the property itself. We report 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.
On flat ground, that last point does more work than people expect. Where there is very little natural fall, small changes — a raised bed, a new drive, a patio laid level with a doorway — can be enough to hold water against a wall. We also look at the condition of the driveway and any culvert or drainage crossing at the road where they are visible.
Inside, we look for what water leaves 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 usually a story about something that happened once.
Permits
The building permits page sets out two rules that are easy to trip over.
The first is that permit applications and payments cannot be submitted by email. They go by post or in person to the building inspector. In a world where most municipalities have moved online, that is worth knowing before you plan a timeline around it.
The second is the payment rule, stated plainly by the township: each permit requires separate payment, so an electrical permit needs its own payment separate from a plumbing permit even when both are applied for at the same time. On a job involving several trades, that means several payments, not one.
The township issues building, mechanical, plumbing and electrical permits, and the building inspector keeps afternoon hours Monday to Thursday. The township office itself is open through the day, closing for an hour at lunch.
It publishes a 2024 zoning ordinance and a zoning map. We have not read them and will not describe what they require, but a 2024 ordinance is recent enough to be worth consulting directly rather than relying on what somebody remembers.
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 records request you make is targeted. We deliver a full written report with photographs, generally the same day, while you still have room to act on what it says.
The housing
LaSalle has one of the flattest housing profiles we work with: 297 units predating 1940, 353 from the 1950s, 345 from the 1970s and 296 from the 1990s, with smaller groups from the decades in between and 201 units built since 2000.
That means there is no useful generalization about a house here, and two properties on the same road can be sixty years apart. The inspection has to start from what is actually in front of it.
On the pre-1940 stock, 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. 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 original construction.
On the 1950s and 1970s houses, service panels are often at or past the point where an upgrade is worth considering, roofs are on a second or third covering, and heating equipment is two or three generations from the original — with a newer high-efficiency appliance fitted into an older chimney or vent arrangement being a common and specific thing we check. Insulation and ventilation reflect the standards of the day, which usually leaves a worthwhile improvement available in the attic.
The 1990s houses are at the first full round of replacements: original roof coverings reaching the end, water heaters on their second, and furnaces and condensers at the age where the next failure means replacement rather than repair. Decks from that period need ledger connections, flashing, fasteners and post bases genuinely examined.
At 97% detached housing on rural Monroe County land, outbuildings are common and deserve proper attention rather than a glance. Pole barns, detached garages and workshops frequently carry their own electrical supply and their own roof and structural questions.
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 waste
Because the township itself does not supply water or handle waste water, both questions have to be answered per property rather than per township.
On the supply side, establish whether an address is served by the water provider or by a private well. If it is a well, a water test is separate specialist work arranged through the county environmental health department, and it is worth doing before you drink the water rather than after — particularly after any well repair.
On the waste side, establish whether there is a septic system. If there is, a septic evaluation is likewise specialist work carried out by or through the county, and it answers questions no visual inspection can: whether the drainfield is functioning, and the real condition of the tank.
What we inspect is the building and everything from the house side of the system inward: the accessible supply and drain lines, the vent arrangements we can see, how fixtures behave when the system is loaded, and the visible condition of any pump, pressure tank and treatment equipment.
On flat ground with a septic system, the interaction between surface water and the drainfield deserves particular attention. A drainfield working in ground that is also receiving every downspout and a sump discharge is being asked to do two jobs at once, and where there is little natural fall the water has nowhere obvious to go. We report the grading and the discharge points so you know what you are dealing with.
The buried line
Whatever a property here drains to, the line running out from the building belongs to the owner, and no visual inspection reaches inside it.
On one of the 297 houses predating 1940, that pipe may have been in the ground for eighty years or more, through more than one era of drain material. We will not name a material from a build year, because no authoritative source establishes what LaSalle 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 flat ground a belly matters more than it would elsewhere, because there is less fall available to carry waste past a low spot.
On a septic property the same camera documents the building drain out to the tank — the owner’s pipe, and the part a septic evaluation does not examine, since that looks at the tank and the field rather than the run between them and the house.
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 LaSalle.

Reviews
Mitch was great and thorough the our inspection. He provided explanations and suggestions throughout the service. Highly recommend!
Jaynie GMonroe, MII 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).

Questions
Four different organizations. Water comes from a separate water provider, drainage and flood management from the county drain commission, septic systems and wells from the county environmental health department, and roads and roadside drainage from the county road commission.
Assessing, zoning, building permits and the cemetery, broadly. It is easy to assume the township can answer a question about your water, your drain or your septic system, and it generally cannot.
Both arrangements exist here — the township links to a water provider and to county well oversight. Confirm it in writing for the specific address, because it changes what you need to arrange before closing.
No. The township states that permit applications and payments cannot be submitted by email; they go by post or in person to the building inspector, who keeps afternoon hours Monday to Thursday.
No. The township is explicit that each permit requires separate payment — an electrical permit needs its own payment separate from a plumbing permit even when both are applied for at the same time. On a multi-trade job that means several payments.
Because there is very little natural fall to work with. Small changes — a raised bed, a new drive, a patio laid level with a doorway — can be enough to hold water against a wall. We report grading, downspout terminations and sump discharge points specifically.
Yes, and at 97% detached housing on rural land they are common and worth including rather than leaving to a later surprise. They often carry their own electrical supply and their own roof and structural questions.
Yes, and flat ground is part of the reason. A belly in the line matters more where there is less fall to carry waste past a low spot. On a septic property it also covers the run between the house and the tank, which a septic evaluation does not examine. A camera inspection is added to the same visit.
