Stucco Repair & Waterproofing
Crack repair, patching, colour matching and moisture control.
Most stucco problems are water problems. The crack or stain you can see is usually the symptom, and patching it without finding the source just hides the damage until it comes back bigger. We diagnose first, then repair.
Finding the actual cause
Water gets into stucco walls in a fairly small number of ways: failed sealant around windows and doors, gutters overflowing down an elevation, sprinklers hitting the wall every morning, a weep screed buried under soil or a new patio, roof-to-wall flashing that was never right, or cracking that has opened far enough to let rain in.
We walk the elevation and work out which of those is happening before we mix anything. A repair that does not address the source is a repair you pay for twice.
Crack repair and patching
Not all cracking is a problem. Fine hairline cracking is normal thermal movement in Florida and is often best left alone or simply coated. Cracks that keep reopening after patching, run diagonally from window and door corners, or widen along their length are telling you something structural or moisture-related is still active underneath.
For patching, matching matters as much as the repair itself. Texture, colour and the way the surface reflects light all have to blend, or the fix reads as a visible scar across the elevation. Older walls that have weathered for years are the hardest to match, and that is the part that takes experience rather than product.
Waterproofing and coatings
Once the wall is sound, coatings and sealants keep it that way. Elastomeric coatings can bridge fine cracking and add a flexible water-resistant layer over the surface. Sealant work around windows, doors, penetrations and control joints handles the places water most often gets a foothold.
Coatings are not a fix for a wet wall. Sealing moisture inside an assembly that is already saturated makes the problem worse, not better. The wall gets dried and repaired first.
When repair stops being the right answer
Soft or hollow-sounding stucco means the material has already separated from what is behind it, and that section is past patching. Widespread efflorescence that keeps returning, or staining and musty smells showing up on the interior side of an exterior wall, point at moisture that has crossed the assembly.
At that point the honest answer is often a larger scope than a patch. We would rather tell you that up front than take the smaller job and have you call us again in a year.
Common questions
Are hairline cracks in stucco a problem?
Usually not on their own. Stucco expands and contracts with heat, and fine cracking is normal in Florida. What matters is whether the same crack keeps reopening after it is patched, whether it is widening, and whether there is staining or softness around it.
Will the repair match the rest of my wall?
That is the goal, and it is the part that takes skill. Texture and colour matching on a wall that has weathered for years is harder than the patching itself. We will be upfront if an elevation is going to be difficult to blend invisibly.
Can you just paint over the cracks?
Coating over active cracking or a wall with a live moisture source hides the problem rather than fixing it, and can trap water inside the assembly. The cause gets addressed first, then coatings do their job properly.
How do I know if water has got behind my stucco?
Common signs are staining that spreads downward, bubbling or peeling paint, white chalky efflorescence, and areas that sound hollow or feel soft when pressed. Interior clues — baseboards pulling away, drywall staining, a musty smell in a closet on an exterior wall — usually mean it has already crossed the wall.
