Northbrook mixes substantial mid-century houses on generous lots with a steady stream of teardown rebuilds, and sits in an area with a real history of heavy-rain flooding. A Northbrook inspection usually comes down to two questions: what has water done to this property, and if the house is new, was it actually finished properly.

Water first
Parts of Northbrook drain toward ditches and forks that have overwhelmed in severe storms, and much of the village is flat enough that drainage is engineered rather than natural. This is the first thing we look at.
We check whether there is an overhead sewer conversion or a backwater valve — both meaning somebody spent real money on a real problem — and whether that valve is accessible for the servicing it requires. Whether the ejector pit is sealed and vented. Whether the sump cycles, where it discharges, and whether there is battery backup on a pump protecting a finished lower level. Then the ordinary causes that account for most wet basements: downspouts at the foundation, grading settled back toward the house, window wells with nowhere to go.
The evidence outlasts the water. Staining at the base of walls, efflorescence, rusted mechanical feet, replaced bottom plates on finished walls — a dry basement in a dry month proves very little on its own.
Teardown rebuilds and newer construction
Northbrook has significant infill rebuilding, so a meaningful share of listings are recently completed houses. New does not mean inspected. We look at what a builder’s schedule tends to compress: flashing and water management at roof-wall intersections, grading and downspout discharge on a lot that was just regraded, attic ventilation and insulation coverage, and whether mechanical systems were commissioned or merely installed.
On a house still under construction we can inspect before drywall — the only point at which framing, rough plumbing, rough electrical and flashing are all visible at once.
The mid-century stock
Outside the rebuilt streets, expect the regional profile: galvanized supply piping closing from the inside, cast iron drains channelling where you cannot see, Federal Pacific panels with their failure-to-trip history, aluminum branch wiring at the later end, and decades of freeze-thaw on masonry, chimneys and parapets. Large lots with mature trees also mean serious root pressure on old sewer laterals.
Radon and sewer
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.
For sewer, the older sections have the clay tile and mature tree combination that makes a scope worth the money. On a newer rebuild the lateral may be new — but it may also be an old lateral reused under a new house, which is exactly the thing a camera settles in ten minutes.
Common questions
The house was rebuilt in 2019. Is there anything to find?
Frequently, yes. Recent construction has its own failure set — water management details, insulation coverage, commissioning — and if the sewer lateral was reused it is now decades older than the house above it.
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 Northbrook 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: Glenview, Wilmette, Buffalo Grove, Highland Park. If you are looking in more than one area, the same inspector and the same scope apply to all of them.
