Weatherproofing and exterior sealing in Rochester, NY

Weatherproofing and exterior sealing in Rochester

Rochester’s freeze-thaw cycles, lake-effect snow, and humid summers take a heavy toll on exterior surfaces. Water intrusion through cracks, gaps, and worn seals leads to rot, mold, and peeling paint within a single season. Weatherproofing and exterior sealing address these vulnerabilities directly. The work involves a thorough inspection of all exterior joints, seams, and transitions—where siding meets windows, where foundation meets framing, around doors, and along rooflines. Each gap is cleaned of debris and old caulk, then filled with a high-grade elastomeric sealant that can expand and contract with temperature swings. For wood surfaces, a penetrating oil-based sealer is applied to repel moisture while allowing the wood to breathe. Masonry and brick receive a silane-siloxane sealer that bonds chemically to prevent water absorption without trapping vapor. The goal is to create a continuous, flexible barrier that keeps liquid water out but allows trapped moisture to escape.

The process begins with a detailed walk-around, noting every point of potential entry. Power washing removes dirt and loose material so sealants adhere properly. All existing caulk is cut out and replaced—layering new caulk over old is ineffective and short-lived. Window and door perimeters are resealed with a paintable silicone that remains flexible for years. Foundation cracks wider than a hairline are routed out and filled with a urethane-based crack filler. For stucco or EIFS systems, a breathable elastomeric coating is applied in two coats, ensuring full coverage over hairline cracks. Finally, a water-repellent sealer is sprayed or rolled onto all exposed masonry, brick, and concrete, penetrating deep into the pores. This comprehensive approach prevents the most common exterior failures in Rochester: ice dam damage, efflorescence on brick, and rot around window frames.
