What we see here

Common repairs in Brentwood

Summer heat on the spa wall

Brentwood summers regularly push past 100°F. That heat, followed by cool nights and a hot spa, works the tile bond on the spa dam wall harder than anywhere else on the pool.

Decks that move

Clay soil swells in wet winters and shrinks in dry summers. Decks shift with it, and the expansion joint takes up that movement until the mastic finally tears.

Faded plastic deck strips

Older decks often still have the original plastic strips. We saw-cut them out and replace them with mastic for a sealed, cleaner-looking joint.
