Home / Locations / Grosse Pointe, MI
Grosse Pointe homes are some of the oldest and grandest in the metro — and most have basement issues no one's properly diagnosed. We work the Pointes carefully.
Grosse Pointe's pre-war estate homes sit on a high water table close to Lake St. Clair. The original foundations are stone, brick, or early reinforced concrete — all of which behave differently than modern poured walls. We don't apply the same template here that we use in Macomb.
Most Grosse Pointe homes need a custom interior drainage path that respects the existing finished spaces, which often means working around servants' staircases, original tile floors, and historic features. Our crew has done this dozens of times — we protect every floor, we cut precisely, and we restore better than we found it.

The local soil & water story
Grosse Pointe — the city proper, distinct from the Farms, Woods, and Park — sits adjacent to Lake St. Clair with a water table 4–7 feet below grade in most of the city. That's significantly higher than inland communities. Combined with the city's collection of pre-war estate homes, original stone and brick foundations, and finished basement culture, this creates a specialized waterproofing problem set we approach differently than Macomb County work.
Local soil is a mixed clay-loam with sand and gravel pockets close to the lakeshore. Water moves through it unpredictably — one Grosse Pointe home can have a chronically wet basement while the neighbor's stays dry. The variable is foundation type and exterior grading more than soil. We diagnose each home individually.
Common problems we see
Grosse Pointe basements present a wider range of problems than newer suburbs because the housing stock spans nearly a century and the foundation types include stone, brick, early reinforced concrete, and modern poured walls. Here's what we encounter most.
Pre-1920 Grosse Pointe estate homes often have field-stone foundations bonded with original mortar. Water enters through the mortar between stones. The fix requires interior drainage plus careful mortar joint repointing — typically $14,000–$22,000 for an estate basement.
1920s–1940s Grosse Pointe homes typically have brick foundations. Water enters through deteriorated mortar joints. We install interior drainage tied to a sealed sump and seal the brick face during the same install. $11,000–$16,000 range.
Nearly every Grosse Pointe basement is finished — paneled rec rooms, wine cellars, secondary kitchens. Interior drainage work requires careful protection of original finishes, often working around servants' staircases or original tile floors.
Lake-proximity water tables mean sump pumps run year-round, not seasonally. Pumps wear out faster. We install commercial-grade Zoeller M98 primaries with high-capacity 2,500 GPH battery backup — sized for the city's reality.

Recent work in Grosse Pointe
Grosse Pointe (city) — 48230
$15,800 over 4 days. Wine cellar's terrazzo floor was protected with three layers of board and felt; we cut around the wine racks and restored the floor with a matching concrete cap. Dry through six months of typical lake-effect weather.
Grosse Pointe Farms — 48236
$21,400 over 5 days. Mortar work alone took two days; drainage another three. The basement now has a finished sump room with sealed lid, paintable cap, and the same drainage pattern that's served this home through over a century of seasons.
Grosse Pointe Park — 48230
$2,600 total. The home didn't need full interior drainage — just a working backup pump and extended downspouts. Previous owner had been quoted $18,000 by another contractor for a full system. Sometimes the simpler answer is the right one.

Grosse Pointe jobs range $11,000–$22,000 for full interior perimeter drainage, depending on foundation type, basement size, and finished-space protection requirements. Stone foundations cost more than brick, which cost more than block. Sump pump and downspout-only work can be $2,000–$4,000.
Yes — careful, slow, and often during the off-season when homeowners can plan around it. We protect original woodwork, tile floors, and finished spaces. Our crew has done this in Grosse Pointe Farms, Shores, and the city proper for over 30 years.
Yes. Interior perimeter drainage doesn't require touching the original foundation face — we cut along the wall-floor joint inside the basement and finish with a paintable concrete cap. For stone foundations needing mortar repointing, we do that work as a separate phase using mortar that matches the original.
We protect every floor, work around finished walls when possible, and clean up at the end of every day. About 80% of our Grosse Pointe jobs are in finished basements. The work is more careful and slower than a standard install, but the basement stays usable.
