Milgard Window Leak Cleanup in Kirkland, WA: 24 Hour Drying

Milgard is a Washington-born window brand found in homes across the Eastside. Kirkland's wind-driven rain tests every window, and when water gets in, it usually starts at the corners, sill or flashing, then runs inside the wall where you cannot see it. Our team checks for hidden water, dries the wall cavity and sill, and repairs stained drywall. We offer same day visits across Kirkland, WA and emergency help 24 hours a day during storms.

Is your window leaking, or is it condensation?

Both make windows wet. Only one means water is getting into your walls.

Where windows leak

Where window leaks usually start

Frame corners

Joints at the corners of the frame can open up and let wind-driven rain in.

Blocked weep holes

Small holes at the bottom of the frame drain water out. If dirt blocks them, water backs up inside.

Flashing

Flashing around the window directs water out. Poor or missing flashing sends it into the wall.

Sill pan

Without a sloped sill pan, water that gets past the window soaks the framing below.

Siding and trim

Gaps in siding or trim above the window let water run behind it.

Sliding tracks

Dirty or worn slider tracks can overflow in heavy rain.

The hidden damage

What a leaking window does inside your wall

Most window leaks are small. But they happen every storm, all winter long, and the water goes straight into the wall below the window.

Rotting framing

The sill plate and studs below the window stay damp and can start to rot.

Wet insulation and mold

Insulation holds water against the wood. A closed, damp wall is a perfect place for mold. If you smell must, see mold inspection.

Stained drywall and floors

Stains, bubbling paint and swollen baseboards below the window are signs it has been leaking a while. Hardwood near the wall can cup too.

How we find it

Thermal imaging and moisture meters map the wet area below and beside the window without opening the wall. See hidden leak detection.

Our process

How we handle a window leak

  1. Moisture map

    Readings and thermal scan around the window.

  2. Find the path

    Corners, weep holes, flashing or siding.

  3. Open if needed

    Small sections of drywall below the window if framing is wet.

  4. Dry and treat

    Wall cavity drying and antimicrobial treatment.

  5. Document

    Photos for your window installer and insurer.

  6. Repair

    Drywall, trim, sill and paint restored after the window is fixed.

Kirkland storms

Why Kirkland windows leak in winter

Lake-facing walls
Homes in Houghton and Lakeview take strong, rain-driven wind off Lake Washington.
Older installs
Windows replaced years ago in Rose Hill and Kingsgate may not have modern flashing or sill pans.
Tall walls
Multi-story condos in Totem Lake collect a lot of runoff above each window.
Prevention

Keep your windows from leaking

  • Clean window tracks and weep holes every fall.

  • Keep caulk and trim around the outside in good shape.

  • Make sure gutters are not overflowing onto windows.

  • Watch for paint bubbles or stains below windows after storms.

  • Keep indoor humidity in check to limit condensation.

  • Ask the installer about flashing and sill pans when replacing windows.

FAQs

Milgard window leak questions

Why is my window leaking when it rains?

Common causes are blocked weep holes, gaps at frame corners, missing or failed flashing, or water running behind siding above the window. Many window leaks are installation problems, not product defects.

Is it condensation or a leak?

Condensation forms on the inside of the glass, often on cold mornings, and is not tied to rain. A leak shows up during wind and rain, usually at the sill or corners, or as stains below the window.

What are weep holes?

Small openings at the bottom of the window frame that let water drain outside. If they are blocked, water can back up into the home.

Does Milgard's warranty cover water damage?

Window warranties usually cover the window itself, not damage to your walls. Installation problems are often the installer's responsibility. Check your warranty and installation paperwork.

Can a window leak cause mold?

Yes. Repeated leaks keep the wall below the window damp, which can lead to mold and rot.

Do you repair windows?

No. We find and repair the water damage. A window installer or contractor fixes the window or flashing.
