FAQs
How do I know when sealant or caulking needs to be replaced (instead of just patched)?
If your exterior caulk/caulking is cracking, shrinking, separating from the surface, or leaving gaps, patching is usually short-lived. Caulk and sealants have a service life—once they lose adhesion or flexibility, water and air can get in. Full replacement restores a properly sealed, movement-capable joint.
Why is exterior caulking (sealant) replacement such a cost-effective building envelope repair?
Because failed caulk/caulking is one of the most common ways water enters a building—especially around joints and openings. Replacing deteriorated sealant early helps prevent bigger problems like concealed wall deterioration, interior damage, and more expensive façade repairs.
What areas of a building typically need caulking and sealant replacement?
Most exterior caulking failures happen at movement joints and transitions, such as expansion/control joints, window and door perimeters, coping joints, and other places where different materials meet and the building moves. These are also common points for water and air infiltration.
