BALCONIES
BALCONIES
A leaking balcony rarely stays a balcony problem. Water travels, and the unit below often pays the price first. We waterproof balconies for apartments, HOA’s, commercial and residential properties with fully bonded membrane systems that seal the deck, flashing and drain penetrations, backed by our leak-detection expertise.
Best for: Apartments, HOA’s, commercial and residential properties with wood-framed or concrete balconies.
