Austin window flashing + leak repair
Window leaks in Austin: find the path, then close it
A wet sill is not a caulk problem. Water is traveling around the window, through failed flashing, or out a stucco return. This site is only about that repair.
Leaking windows in stucco, stone, and framed wall assemblies across Austin.

Central Texas sun cooks sealant. Then a hard rain finds the first open corner at the head or jamb.
On stucco and stone walls the leak often shows up inside the house two feet from the window because the water ran behind the finish.
Re-caulking the glass does nothing if the head flashing, sill pan, or weep path is wrong.
What to watch for
Small signals can mark a larger hidden path.
- Water stains under a window after rain
- Soft drywall or bubbling paint at the jamb
- Musty smell at a window seat or built-in
- Stucco cracks that start at a window corner
- A new window that still leaks because the flashing was skipped
Field standard
Trace first.
Repair second.
How we stop a window leak
Find the opening. Follow the water. Rebuild the drainage path.
Caulk can close a surface crack, but it cannot replace missing flashing or a failed weather barrier behind the wall.
Inspect the head
We check the top corners, head flashing, perimeter seal, and the way the finish meets the window frame.
Trace hidden damage
Once water gets behind the finish, it can travel down the sheathing and collect far below the window.
Tie it together
New flashing and membrane must lap into the wall system so water drains outside instead of into the framing.
The field plan
Find the cause before pricing the close-up.
Clear scope, honest boundaries, and a repair built around the assembly—not the stain.
AUS / 01
We open the finish only as far as needed, trace the leak, and rebuild the flashing path: head flashing, jambs, and a sill that actually drains out.
On stucco we patch the return so the new metal is lapped into the weather barrier, not smeared with more paint.
You get one trade on one problem. We do not use this page to sell floors or decorative finishes.
What a window leak can hide
The wet spot inside is often the end of the path.
These actual repair photos show why we inspect beyond the visible stain. Water behind stucco or stone can reach a much larger section of sheathing.
Swipe the project stages
Wood sheathing first. Blue waterproofing second.
Drag the handle to see the installation order. New wood sheathing closes and strengthens the wall; then the blue waterproofing creates the continuous drainage layer. The photos were taken from different positions, so this shows project progress rather than an identical camera-angle comparison.

Straight answers
Before we open the wall.
Can you match the stucco around the window?
Yes. The patch is part of the leak repair. We match texture and color as close as the existing finish allows after it cures.
Do you replace the window or only the flashing?
If the unit is sound we keep it and rebuild the flashing. If the frame is rotten we say so before we start.
