Kolter Homeowner Guide

Exterior Caulking Exterior caulk is found around door and window frames. The elastic sealer prevents air leaks and water entry. Over time, caulk deteriorates and separates from the surface on which it’s applied. For that reason, it’s vital to inspect caulked areas and remove and reapply if the existing caulk is deteriorating or separating. Otherwise, moisture may get behind the siding or wood frames and cause rotting. The frames of doors and windows may begin leaking water if the caulk is allowed to deteriorate too long. Care and maintenance The following tips will help maintain the exterior caulking on your home.

Checking caulk Check for deteriorating or separating caulk once or twice each year. Pay particular attention to the following areas:

Between foundation and siding.

Door and window frames.

Objects such as outlets, pipes, and vents that protrude from an exterior wall.

Objects such as chimneys and vents that protrude from the roof.

Angles and corners between different siding materials.

HOME TIP: Use only elastomeric caulk for repairs.

HOME TIP: Don’t apply acrylic caulk over silicone caulk or silicone caulk over acrylic caulk. The two will not bond properly.
