What goes into a lasting stucco repair
Removing failed stucco without loosening sound stucco
Loose stucco has to come off before a patch can bond. The risk is that heavy blows also break the grip of sound stucco next to it. Preservation guidance calls this over-sounding and warns against it.
We cut the boundary first with a saw or sharp tools, then remove the loose material inside that line. The aim is a repair area with firm edges all the way round. If more stucco lets go during removal, we stop, show you, and agree the new boundary before continuing.
Corroded corner bead and casing bead
Metal beads form the corners and edges of many stucco chimneys. When they corrode, the stucco along the corner can crack in a straight line, bulge or lose its edge entirely. Corners take knocks as well as weather.
A corner repair usually means cutting back the plaster on both faces, replacing the corroded bead with a corrosion-resistant one and rebuilding the coats. The corner is a visible line, so we take care over its straightness and texture. The estimate shows how far onto each face the corner repair reaches.
A horizontal stucco crack near the roof line
A crack running across the chimney close to the roof line deserves attention. It can reflect movement between the chimney and the roof, a change in the base material, or water getting behind the plaster at the flashing.
We look at the flashing, the roof surface and the stucco edge together. If the crack follows a joint between two materials, a rigid patch alone may crack again. We explain what we believe is happening and which repair suits that cause, before any plaster is removed.
Routing a crack before it is filled
A crack that carries water is often widened slightly along its length with a small cutting tool. Routing gives the repair material a clean channel with sound sides instead of a thin, dirty line.
The channel is cleaned and dampened, then filled with a material chosen for whether the crack still moves. The surface is finished to match the texture around it. Routing leaves a neater and more durable line than smearing a patch over the top, and the estimate lists each crack treated this way.
Stucco work we separate on the estimate
- Repair boundary cut to sound edges
- Leveling coat brought to the wall plane
- Finish coat texture matched
- Water source listed as its own item
Chimney stucco questions we hear in Biscayne Island
Can new stucco go straight over the old surface?
Only where the old stucco is sound, clean and firmly attached, and even then a new finish is a surface treatment. Loose or hollow areas have to come off first. Spreading new plaster over failing stucco usually fails with it.
Should I pressure wash the chimney before you come?
Please do not. High pressure can drive water into cracks and loosen weak plaster, which makes the inspection harder to read. Leave the surface as it is, and we will look at it in its current condition.
Can you repair the stucco if the chimney top also leaks?
We can, but the top should be dealt with first or at the same time. A patch below a leaking top tends to fail early. The top repair is listed separately, and we explain the order before you approve anything.
