A flexible sealant squeezed into gaps between materials to block air, water, and drafts.
Caulk is a flexible sealant compound applied to fill gaps, cracks, and joints between building materials to prevent air, water, and pest infiltration. It is available in silicone, latex, polyurethane, and butyl rubber formulations, each suited to different substrates and exposure conditions. Proper caulking at penetrations, perimeters, and transitions is essential for weatherproofing and energy efficiency.
Before painting, the crew caulked all corner joints and the gap between the baseboard and hardwood floor for a clean, professional finish.
