- Window Well Drains — Prevent egress window wells from flooding your basement during heavy Michigan rain events.
Why Detroit Basements Leak
Metro Detroit sits on glacial clay that holds water like a sponge. After the 2021 and 2023 flooding events, thousands of homeowners discovered their waterproofing was inadequate. Aging cove joints — the seam where your basement floor meets the wall — are the most common entry point for water in Detroit-area homes. Our interior drain systems target this directly.
