Start with conditions, not a product
A damp floor in a Lansing basement could mean roof water finding the wrong path, grading that slopes the wrong way, groundwater pressing on the wall, a cracked joint, or plain summer humidity -- and no two of those get fixed the same way.
Build a complete scope
- Where water enters, and whether it appears in thaw or in heavy rain
- Whether the wall is old block, poured concrete, or something older still
- Exterior grading and downspout discharge corrected ahead of interior work
- Sump capacity, discharge routing, and behavior in a winter power cut
- Restoration of finished space, and the terms that limit the warranty
Lansing context
Lansing's housing stock runs from early in-town neighborhoods near the Grand River and Red Cedar River confluence through decades of postwar ranch construction tied to Oldsmobile and REO Motor Car Company employment, much of it built on mid-Michigan's clay-heavy glacial till. That clay expands when saturated and contracts as it dries, exerting real lateral pressure on foundation walls, and combined with roughly 46 inches of annual snowfall and hard seasonal freeze-thaw cycling, it's a large part of why grading, gutters, and interior drainage stay in steady demand across greater Lansing basements of every era.
