Interior Plaster Repair After the Leak
Water stains on a lobby wall or a guest room ceiling are usually the inside end of an exterior leak. We close the leak in the stucco or EIFS, then repair the plaster inside, so property managers deal with one contractor instead of two.
- Leak fixed outside first
- Water-damaged plaster
- Occupied buildings
- Homes too

Fix the envelope, then the interior
On commercial buildings, interior wall damage and exterior wall leaks often get handled by different vendors. Maintenance patches the room, the stain returns after the next storm, and nobody connects it to the failed window sealant or missing flashing three floors up.
Because our work is the exterior wall, we start there. We trace the water with moisture readings and water testing, repair the stucco, EIFS, sealant or flashing that let it in, and confirm the wall is drying. Only then do we cut out soft plaster or gypsum, treat stains and rebuild the interior surface to match the rooms around it.
We do this in hotels, offices, multifamily buildings, retail spaces and medical suites, working around guests, tenants and staff. Rooms are contained so dust stays in the work area, and repairs are scheduled by unit or floor. Homeowners with the same problem get the same approach. Start with leak detection or see our commercial services.

Interior damage from exterior leaks
These are the interior signs that usually point to a problem in the building envelope.
Stains below windows
Brown rings or tide lines under window corners often trace back to failed perimeter sealant or sill flashing.
Bubbling & peeling
Paint lifting off plaster or drywall shows moisture is coming through the wall from behind.
Soft or crumbling plaster
Plaster that has stayed wet loses strength and must be cut back to sound material.
Musty odors
A damp smell near an exterior wall can mean wet sheathing or insulation inside the cavity.
Recurring damage
The same unit or suite needing repairs after every storm is a sign the leak was never fixed.
Turnover repairs
Plaster and paint restored between tenants or guests, scheduled to the unit turnover.
How deep the repair goes
The interior scope follows the moisture readings. A stain on dry, sound plaster may need only a stain-blocking primer and paint. Swollen or soft areas are cut out and patched. When insulation or framing behind the wall is wet, the cavity is opened, dried and repaired before the surface is closed.
Managers get photos of what we find and approve changes in Jobber before work continues, which helps with owner reporting and insurance documentation.
| Condition | Repair | Finish |
|---|---|---|
| Stain only, dry | Seal and prime | Repaint |
| Surface damage | Skim and patch | Texture matched |
| Soft plaster | Cut out and rebuild | Blended to room |
| Wet cavity | Open, dry, repair | New surface |
From the leak to the finished room
Interior repairs only last when they follow an exterior fix and a confirmed dry wall.
Trace the water
We take readings inside and out, test suspect windows and joints, and identify the entry point on the exterior.
- Interior readings mapped
- Exterior water testing
- Source documented
Repair the exterior
Stucco, EIFS, sealants or flashing at the leak are repaired, then we confirm the wall is drying before going inside.
- Leak closed
- Substrate repaired
- Drying confirmed
Restore the interior
Damaged plaster is removed and rebuilt, stains sealed, and the surface textured and painted to match the room.
- Work area contained
- Texture matched
- Room handed back clean
Same unit, same stain, every storm?
