Basement waterproofing in Sylvan Glen, Troy
Updated October 20, 2026
Sylvan Glen near Rochester Road and Square Lake sits on Selfridge loamy sand: sandy on top, slow-draining below. Rain soaks in fast, then sits on the denser layer at footing depth. Basements here can be dry for years and then leak in a wet spring when that perched water reaches the wall.
Where: Rochester Road and Square Lake · Housing: 1960s–70s ranches and colonials · Mapped soil: Selfridge loamy sand, somewhat poorly drained
What contractors usually find in Sylvan Glen basements
- Seepage that appears only in the wettest springs and then disappears.
- Damp cove joints on the low side of the lot.
- Window wells that drain fine in summer and fill in spring.
Which fix usually fits
- Waterproofing: Interior tile on the wet side, with window-well drains tied in, handles the perched water.
- Sump pumps: A sump with a backup is the safeguard for the spring the perched water finally wins.
Also on this site: crack repair, crawl space. The contractor decides the scope at the house; these are the usual starting points, not a diagnosis of your basement.
Before you send the form
- Note which year the leak started and whether it was a wet spring.
- Check the window wells for gravel and a drain.
- Find where the downspouts and sump discharge end up on the sandy surface.
- Have the build year ready (most houses are 1962–1978).
Sylvan Glen questions
The basement was dry for 20 years. Why now?
Perched water on sandy-over-dense soil only reaches the wall in the wettest years, and a failed downspout or a new patio can tip it. The free estimate finds the trigger.
Do I need a full perimeter system?
Often not in Sylvan Glen. One or two walls plus the wells is a common scope.
