Window & Door Leak Repair in Dearborn, Michigan

Window leak repair in Dearborn seals, reflash, and corrects the drainage paths where wind-driven rain, ice-dam runoff, and age-weakened seals let water past the frame — staining that starts at a head or sill and tracks the rough opening, basements where window wells fill during heavy Wayne County storms, and older units whose glazing compound and exterior caulk have aged past service life. A window leak is a building-envelope failure with a clear path: water finds the failed seal line, enters the rough opening, and wicks into drywall, sill plates, and sometimes the cavity below. Water Damage Pros US diagnoses the actual entry path before opening anything — window leak repair across Dearborn and Wayne County.

Why Windows Leak in Dearborn Homes

• Failed glazing compound and frame seals — age, UV, and freeze-thaw crack the original bead
• Deteriorated exterior flashing and caulk — head and side laps that let water behind the trim
• Clogged or missing weep holes — frame channels that cannot drain what collects inside the sash
• Sill slope and seal failure — standing water at the meeting rail or sill that finds an interior path
• Window wells filling during storms — basement units taking bulk water over the sill or through failed frames
• Ice-dam runoff above — meltwater forced under head flashing when the roof edge backs up in winter
• Poor original installation — missing pan flashing or housewrap integration at the rough opening

Dearborn housing stock shows each of these by era: pre-war wood windows with glazing compound that has long since hardened and cracked, mid-century aluminum and early replacement units with caulk lines past their life, and newer vinyl installs where weep paths or head flashing were incomplete from the start. Because Michigan Avenue corridor buildings and multi-family stock share wall planes, a failed head flashing on one unit often shows as interior staining in the unit below or beside it — the entry path is at the window, but the visible damage can appear one floor away until mapping confirms the route.

Our Window Leak Repair Process

1. Trace the entry path — exterior inspection plus interior moisture mapping
2. Rule out adjacent sources — roof, wall, and ice-dam paths checked before blaming the unit
3. Clear drainage — weep holes, frame channels, and sill pans opened and verified
4. Reseal failed lines — glazing compound, frame-to-sash, and interior seals replaced as specified
5. Repair or replace flashing — head, jamb, and sill flashing corrected at the rough opening
6. Correct surrounding grade and wells — surface water redirected before the next storm
7. Dry any wet cavity found — readings before close-back when water already reached framing
8. Document before and after — entry path evidence for insurance and your maintenance file

Re-caulking the interior trim of a leaking window is how people paint over a symptom for three seasons in a row — water is still entering at the exterior seal line or head flashing, trapped against the rough opening, and the stain returns every time the wind drives rain from the same direction.

Window Leak Repair Costs in Dearborn

Scope	Typical range	Typical work
Weep clear + reseal single unit	$150 – $600	Frame and sash seals
Head / jamb flashing repair	$400 – $2,000	Exterior access
Window well drainage + cover	$300 – $1,500 per well	Grade, drain, grate
Multi-window storm damage scope	Quoted	Units affected
Repair + dry wet rough opening	$600 – $4,000+	Seal path + mitigation

Costs track access (single-story versus upper floor), how many units share the failed detail, and whether the rough opening already needs drying and selective material removal — exterior flashing work on a second-story unit costs more access labor than a basement well drain in open grade. We separate envelope repair from any interior dry-out so the claim shows the cause correction and the water damage mitigation as distinct lines.

Keeping Water Out Between Storms

• Clear weep holes each season — paint, overspray, and debris block them silently
• Inspect exterior seal lines after winter; renew cracked caulk and glazing compound
• Verify head flashing sits proud of siding and drainage plane, not behind it
• Keep window wells drained and covers clear of leaves and ice
• Grade soil and mulch below sill height — never pile soil against the frame
• Address ice-dam risk at the roof edge so meltwater cannot force head joints
• Walk the interior after every major storm — a new stain means a new look at the exterior path

Wayne County weather stresses the same faces repeatedly: wind-driven rain from one direction during summer storms, freeze-thaw cracking winter sealants, and ice-dam meltwater at upper openings each thaw. Windows that take water from the same vector year after year need the flashing and seal at that vector corrected during dry weather — waiting for the next stain to appear means another season of wet rough openings and diminishing salvage options for the materials behind the trim.

Serving Dearborn and Wayne County

Window leak repair runs across Dearborn, Melvindale, River Rouge, Lincoln Park, Allen Park, Dearborn Heights, and greater Wayne County — upper-floor units where storm stains trace down from a failed head flashing, basement windows in window wells that fill after heavy cloudbursts, and multi-family buildings where one unit’s exterior seal failure shows as moisture in the party wall or unit below. We pair the envelope fix with mapping and any needed cavity dry-out so the window is sealed against the next storm and the materials already wet are not closed back in place for someone else to discover. Serving Michigan Avenue corridor buildings, pre-war single-family stock, and rental properties where repeated maintenance paint jobs have hidden seal lines past their service life.
