Window & Door Leak Repair in Birmingham, Michigan

Window and door leak repair in Birmingham fixes the water damage that shows up one stain at a time. Oakland County weather attacks windows from both directions: wind-driven rain pushes sideways through worn seals during storms, and Michigan’s freeze-thaw cycle opens hairline gaps in caulking every winter that leak every spring. In these homes the water doesn’t announce itself — it tracks down inside plaster walls, stains the sill, warps original trim, and grows mold where nobody looks until the musty smell gives it away. Water Damage Pros US repairs window and door leaks across Birmingham and Oakland County, from the flashing outside to the plaster inside.

How Windows and Doors Let Water In

• Failed glazing and seals — decades of repainted-over putty on wood windows, and IGU seals that fog and fail after 15–20 years.
• Worn or missing flashing — head flashing and sill pans that were never layered right, or have rusted and split, let rain straight into the wall.
• Eroded stone sill drips — the pre-war homes’ stone sills lose their drip edges, channeling water back at the wall beneath.
• Clogged weep holes — weep systems designed to drain window frames silt shut and back water into the cavity.
• Wind-driven rain pressure — storm gusts push water through gaps gravity would never reach, especially on west- and north-facing walls.
• Ice dam back-up — winter ice dams push melt under roof edges and down into top-floor window openings.

Our Window Leak Repair Process

1. Water testing and entry-point location — we trace the actual leak path; the stain on the plaster is almost never where the water gets in.
2. Exterior seal and flashing repair — failed glazing, flashing, sill pans, and weep systems are repaired or replaced with correct materials for the window’s age.
3. Interior cavity inspection — moisture mapping finds how far water traveled into the wall, insulation, and framing.
4. Drying and treatment — wet cavities dry and get antimicrobial treatment before closing, stopping mold before it starts.
5. Interior restoration — plaster, drywall, sills, trim, and paint restored to match the room — original profiles preserved where they exist.
6. Verification — the repair is water-tested before we leave, and every similar window on the wall is checked for the same failure.

A window stain that “dries out” every summer is still rotting the wall behind it. In plaster construction the cavity damage grows silently under intact paint — by the time the sill feels soft, the repair is framing-deep. Catch the leak while it’s still a seal job.

Wind-Driven Rain and Oakland County Homes

Birmingham’s mature canopy and open lots shape its window-leak patterns. Homes on the exposed corners of the older districts take west- and north-facing wall failures first — decades of repainted-over glazing on original wood windows crack open in freeze-thaw and leak with every sideways storm. The pre-war homes’ stone sills add their own path: eroded drip edges channel rain straight back at the wall beneath, staining plaster two feet below the window. Postwar ranches and colonials run early aluminum and vinyl units where hardened glazing and silted weep holes fail quietly behind siding. Every few winters, the ice-dam season pushes melt into top-floor window openings along the eave lines. Each scenario ends the same way when caught early: a $300 seal repair instead of a wall rebuild.
