Deck-O-Seal & Expansion Joint Sealing

Protect the Gap Around Your Pool

The joint between your pool coping and surrounding deck is designed to allow movement, but it also needs to be properly sealed. Deck-O-Seal helps keep water from getting into the space behind the coping and around the pool structure, helping protect against water intrusion, erosion, and potential damage over time.


When this seal becomes cracked, separated, or deteriorated, water can find its way where it shouldn’t. We can replace worn-out sealant and restore a clean, flexible seal around your pool.
