    Water Intrusion Repair

    Removing failed caulk, prepping the joint, and installing fresh coastal-rated sealant to stop leaks at windows, sills, and trim.

    Commercial Buildings

    Storefronts, offices, restaurants, hotels, and retail centers. Perimeter caulking and expansion joint sealing on glass, EIFS, and panel systems.

    Post-Construction Sealing

    Final perimeter caulking and weatherproofing for new builds, renovations, and window replacement projects so the envelope is sealed correctly from day one.

    Built for Coastal Conditions

    Standard caulk doesn't last on the Gulf Coast. Salt, UV, hurricane-force wind, and constant humidity break down low-grade sealant in just a couple of seasons. We use exterior silicone and hybrid polyurethane products rated for coastal exposure, prep every joint correctly, and tool the bead so it stays watertight for years.

    FAQ

    Caulking & Weatherproofing — Frequently Asked Questions

    Window caulking and weatherproofing is the process of inspecting, removing failed sealant, and re-sealing the joints around your windows and doors with high-grade silicone or polyurethane sealant. It blocks water intrusion, air leaks, and salt-air corrosion — which is critical on Gulf Coast homes that take constant wind, rain, and humidity.

    Common signs include cracked, peeling, or missing caulk around exterior window frames, water stains on interior walls or sills, drafts near windows, condensation between panes, or visibly rotted trim. On coastal homes, brittle or chalky sealant is a sign UV and salt have broken it down and it's time to reseal.

    We use professional-grade exterior silicone and hybrid polyurethane sealants rated for coastal exposure, UV, and high-movement joints. The product we choose depends on the substrate — stucco, EIFS, brick, Hardie, vinyl, or wood — and on whether the joint will be painted. Everything we install is paintable, mildew-resistant, and built to last.

    Yes. Failed window seals are one of the biggest sources of air leakage in a home. Re-caulking and weatherproofing your windows reduces drafts, helps your HVAC run less, and can noticeably lower cooling costs during Gulf Coast summers.

    Yes. We re-seal exterior window perimeters and expansion joints on condos and commercial buildings using boom lifts, swing stages, scaffolding, or rope (wire) access depending on the building. We also handle storefront glass perimeter caulking and weatherproofing for property managers across Baldwin County and the Florida Panhandle.

    Yes — and most clients prefer it. We clean the windows first so we can clearly inspect every joint, then re-caulk anything that's failed. Bundling the two services saves a separate trip and keeps your windows looking and performing their best.
