Window Replacement in Stucco Walls
Replacing a window in a stucco house is as much a wall job as a window job. The stucco around the opening has to be cut back, the opening flashed so it stays dry, and the wall rebuilt so the new window looks like it was always there.
- Stucco cut back cleanly
- Openings flashed
- Rot repaired
- Patch matched

Getting a window out of stucco without a leak
In a siding house, trim boards come off and a new window slides in. In a stucco house, the window’s nailing flange is buried under lath and cement, and the weather barrier around it is lapped into the stucco. Pulling the old unit means cutting a band of stucco from around the opening, and that band is exactly where most window leaks start.
Many older stucco homes in Georgia were built with windows that have no sill pan and head flashing tucked behind the barrier, or with only sealant between frame and wall. Replacement is the best chance to fix that. With the stucco cut back, we can see the sheathing at the corners and sill, replace any that is soft, install a sill pan and flashing tape in the correct order, and lap the head flashing over the flange.
Then the wall is rebuilt: new lath tied into the existing, base coat reinforced at the corners where stucco tends to crack, a proper sealant joint at the frame, and a finish blended to the rest of the house. If you have stains around your current windows, ask about leak detection first. For window leaks without replacement, see stucco flashing.
Each window replacement covers
The window is one part. The work around it decides whether the wall stays dry.
Careful cut-back
A straight band of stucco removed around the opening, sized to reach the flange and barrier without disturbing more wall than needed.
Opening inspected
Sheathing and framing at the sill and corners checked for rot once the old window is out.
Sill pan & flashing
A sloped sill pan, side flashing tape and a head flashing lapped in the correct order around the new unit.
Window set & sealed
The new window set level and plumb in the opening, fastened through the flange and sealed at the frame.
Wall rebuilt
New lath, base coats reinforced at the corners, and a finish textured to match the existing wall.
Color blended
Custom-mixed color so the patched band around the window disappears into the elevation.
Often paired with this work
Most wall problems involve more than one part of the envelope.
Stucco Waterproofing
Stucco is not a waterproof skin on its own.

Stucco Waterproofing Coatings
A coating is a long-term decision for a building: it changes how the wall handles rain, vapor and movement for years.

Waterproof Coating Systems
Your house may have stucco on the upper walls, a parged block foundation below and a brick or concrete porch in between.

Commercial Waterproof Coatings
On a commercial building the coating is rarely the hard part.

Stucco & EIFS Protection Coatings
Hard coat stucco and EIFS look alike from the street, but they are built very differently and tolerate different products.

A facade that is ten or twenty years old is usually not failing everywhere.
Learn moreFull replacement or insert window?
An insert or retrofit window fits inside the old frame without disturbing the stucco. It is less work but leaves the original flashing, and any leak around it, in place, and it slightly shrinks the glass area.
Full-frame replacement removes the old unit entirely and is the only way to correct the flashing and repair rot at the opening. In stucco homes with any sign of water at the windows, it is the approach we recommend.
| Factor | Insert window | Full replacement |
|---|---|---|
| Stucco disturbed | No | Band around opening |
| Flashing corrected | No | Yes |
| Rot at the opening | Stays hidden | Found and repaired |
| Glass area | Slightly smaller | Same or larger |
| Best when | Opening is dry | Leaks or rot suspected |
How we replace a window in stucco
The new window closes up the opening; stucco work follows over the next days as each coat cures.
Check & measure
We check moisture around each window, measure the openings and explain where the stucco will be cut and how it will be finished.
- Moisture checked
- Openings measured
- Patch plan explained
Remove & flash
Stucco is cut back, the old unit removed, damaged sheathing replaced and the new window installed with sill pan, tape and head flashing in order.
- Rot replaced
- Sill pan installed
- Head flashing lapped
Rebuild & blend
Lath and base coats are rebuilt and cured, the finish is textured and colored to match, and a sealant joint goes around the frame.
- Base coats cured
- Texture matched
- Perimeter joint sealed
