Buffalo Grove is a planned suburb of the 1970s, 80s and 90s, straddling the Cook and Lake county line, with a very high proportion of townhomes and association-governed housing. That combination produces a specific inspection: an age cohort whose original systems are all expiring together, and a purchase where the association’s finances matter as much as the building’s condition.

An age cohort, not a style
Houses built inside a twenty-year window fail on the same schedule. In Buffalo Grove that means:
- Polybutylene supply piping — gray flexible plastic used from the late 1970s into the 1990s, with a history of failures at the fittings. Insurers ask about it and some decline it outright.
- Aluminum branch-circuit wiring at the older end of the range, needing connections rated for aluminum at every device.
- Hardboard and composite siding that swells and delaminates at the bottom course and behind gutters, where it stays wet.
- Failed insulated-glass seals — permanent fogging between panes. Cosmetic individually, but there are often twenty and they are priced per window.
- Second- or third-cycle mechanicals, or in many houses still the first. We photograph data plates so you get real ages.
If it is a townhome, read the reserve study
We inspect the unit and the systems serving it. Roofs, siding, shared plumbing risers, private roadways and common mechanicals belong to the association — and those are exactly the items that produce special assessments. An association with a twenty-five-year-old roof and a thin reserve fund is a financial finding the walls will not show you, so read the reserve study and two years of meeting minutes as carefully as you read our report.
Where moisture inside a unit originates in a common element, we will say so plainly, because that determines who pays to fix it.
Drainage on flat clay
This is flat ground with heavy clay soil, so water does not drain so much as sit, and the load falls on engineered drainage — sump pumps, drain tile, downspout extensions and swales between buildings. The failures are mundane: a swale filled in for a level lawn, downspouts ending at the foundation, a sump discharge looping back to the wall, no battery backup on a pump serving a finished lower level. We check that the sump actually cycles.
Radon
Radon is common across northern Illinois — this is glacial till, and elevated readings are ordinary rather than exotic. Illinois requires sellers to disclose what they know but does not require anyone to test, so a blank disclosure means only that nobody has looked. We are IEMA-licensed and test with continuous monitors rather than charcoal kits, which gives you hour-by-hour data instead of one averaged number — the difference matters when a result lands near the 4.0 pCi/L action level and you have to negotiate on it.
Common questions
How do I tell if the house has polybutylene?
It is usually visible at the water heater and where pipes enter fixtures — gray, flexible, no threads. We look specifically for it in this age range and photograph what we find, because it is an insurance conversation as much as a plumbing one.
Does the county line matter?
For the inspection, no. For taxes, schools and which municipality handles permits, yes — worth confirming which side a specific address falls on.
Can you inspect on a weekend?
Yes. We do not schedule evenings.
What the inspection does not include
A home inspection is a visual, non-invasive evaluation of the systems accessible on the day of the inspection. We do not open walls, move stored belongings, dismantle equipment, or predict how long a component will last. We do not inspect septic systems or test well water. We also do not perform the structural engineering analysis some findings call for. A sewer scope needs an accessible cleanout; standing water or an inaccessible line limits what the camera can show.
We do not perform repairs, sell remediation, or take referral fees. We measure and interpret; you decide what to do about it.
What the inspection covers: every inspection we perform in Buffalo Grove follows the same scope. See our home inspection services and what each one covers — pre-purchase, pre-listing, new construction, condo and multi-unit — plus in-house radon, mold, and sewer scope testing.
Nearby areas we inspect: Palatine, Northbrook, Vernon Hills, Arlington Heights. If you are looking in more than one area, the same inspector and the same scope apply to all of them.
