Professional caulking and sealing for St. Matthews homeowners

St. Matthews homes deserve careful, low-pressure cleaning that protects brick, vinyl and stucco — not the high-pressure blasting that strips paint and forces water into your siding. We've been the soft-wash choice for St. Matthews families for years.

Most homeowners don't think about caulking until they see water damage — and by then, it's expensive. Exterior caulk and sealant joints around windows, doors, driveways and patios typically last 5–10 years before they crack, shrink or pull away from the surface. When they fail, water infiltrates the wall assembly, driving up energy bills, inviting rot behind the siding, and setting the stage for costly repairs. We use the industry's highest-quality urethane and hybrid sealants — Sika, Dymonic and BASF products chosen for the specific joint type and weather exposure. We don't use cheap acrylic caulk that shrinks and cracks within a year. For brick and masonry exteriors, we apply professional-grade silane/siloxane water repellants that bead water off the surface without changing the look or breathability of the brick. Louisville's freeze-thaw winters are especially hard on masonry — water infiltrates micro-cracks, freezes, and expands, widening those cracks year after year. A proper water repellant treatment stops that cycle. We pair our caulking and sealing work with a thorough exterior inspection so you know exactly what's failing, what can wait, and what we recommend addressing now. As a firefighter-owned company, we're not here to upsell you — we're here to protect your home.
