Water is a foundation's worst enemy. Once moisture works its way through concrete or block walls, it leads to wet basements, musty crawl spaces, mold, and over time, serious structural damage. Pro Seal's exterior foundation sealing creates a durable waterproof barrier that keeps water out and protects one of the most expensive parts of your home or building.
Professional Waterproof Barrier
We thoroughly clean and prepare the exterior foundation wall, then apply a heavy-duty waterproof sealant that bonds to concrete and block. The result is a continuous, flexible membrane that blocks water intrusion and stands up to ground moisture season after season.
Built for Connecticut Conditions
Heavy rain, snowmelt, and repeated freeze-thaw cycles put constant pressure on foundations across central Connecticut. Our sealing system is designed to handle these conditions, helping prevent the cracking, leaking, and deterioration that come from years of water exposure.
When to Seal Your Foundation
If you notice damp basement walls, efflorescence (white chalky residue), musty odors, or hairline cracks, it's time to act. Sealing is also smart before finishing a basement or whenever the foundation is already exposed, addressing water now is far cheaper than repairing damage later.
