Frequently Asked Questions — Stucco Waterproofing NYC
Signs include hairline cracks, dark staining or discoloration, a chalky or soft surface, and musty odors near exterior walls. If water is getting behind the stucco, mold and structural damage usually follow, so it’s best to have it inspected as soon as these signs appear.
Exterior stucco waterproofing applies coatings to the outside face of the wall to stop moisture from entering in the first place, while interior stucco waterproofing seals interior surfaces to stop moisture that has already gotten in. Most properties only need exterior treatment, but interior sealing adds a second line of defense in problem areas.
Yes — stucco crack repair and waterproofing go together. Cracks are sealed and filled first, then a waterproof coating or sealant is applied over the repaired area so moisture cannot re-enter through the same spot.
A quality waterproof coating typically lasts 5 to 10 years depending on climate exposure and installation quality, though flashing, caulking, and drainage details should be checked yearly since those areas fail before the main coating does.
Yes — we waterproof stucco foundations in addition to walls, applying specialized coatings and sealants at the base of the building to keep moisture out of the foundation and protect the long-term stability of the structure.
