Why Grosse Pointe basements take water
The Grosse Pointes have some of the best-built older housing in the region, and some of the deepest basements. Both are worth protecting properly rather than patching.
Most of what we work on here was built between roughly 1910 and 1940 — substantial homes with full, deep basements, often finished at some point over the last century. Two things drive the water problems. The lake keeps the water table high, so there is steady hydrostatic pressure against walls sitting well below grade. And a century of freeze-thaw has worked on the original mortar and the cove joint, so the water has somewhere to go. Because these basements are frequently finished, the damage is often well underway before anyone sees it — the first sign is a musty smell or basement mold behind panelling rather than visible water. We are careful in finished spaces: we trace the entry point before opening anything up, and scope the work so you are not tearing out more than the repair actually requires.
Grosse Pointe is about twenty-five miles from our New Haven shop — a straightforward run down Jefferson, and worth it for the kind of work these homes need. We inspect in person, explain what is causing the water rather than just where it shows, and put a real number in writing before anything starts.

Questions Grosse Pointe homeowners ask
Can you waterproof a finished basement without gutting it?
Usually, yes — and it is the first thing we look at. We trace where the water is actually entering before opening anything, so the work is scoped to the entry point rather than the whole perimeter. Sometimes an interior drain does need the bottom of a wall opened up; when that is the case we tell you before we start, not halfway through.
Why do these older homes get mold before they get water?
Because the basements are usually finished. Moisture moves through the wall into the framing and drywall behind the panelling, feeding mold growth long before enough gets through to puddle on the floor. A musty smell in a Grosse Pointe basement is worth investigating early — it is often the only warning you get.
Do you charge extra to come to Grosse Pointe?
No. It is about twenty-five miles from the shop and we work there regularly. You get the same free in-person inspection and the same written number as anywhere else we serve.
My basement flooded in the June 2021 storm. Was that a waterproofing problem?
Possibly not. Grosse Pointe Farms reported more than six inches of rain in the early hours of June 26, 2021, with the downstream Fox Creek Enclosure filling to capacity and flooding concentrated in the Inland District between Ridge and Mack. Water that came up through a floor drain that night was most likely a sewer backup, and waterproofing does not stop that — it is a backflow and sewer-lateral question, and Grosse Pointe Park requires a permit for lateral work. Water that seeps through the walls or the cove joint days after a rain is groundwater, and that is what we fix. We will tell you which one you had.
Do you cover all of Grosse Pointe?
Yes — every Grosse Pointe ZIP (48230, 48236). Grosse Pointe is about 25 miles from our New Haven shop, and the inspection is free wherever in town you are.
How does the free inspection work?
We come out, look at the basement, and trace where the water is actually getting in rather than guessing from the driveway. You get a written scope and a real number before any work starts — no pressure, and no obligation to book on the spot.
