Pool Mastic and Caulking Replacement in San Diego County

San Diego County

San Diego County is really two jobs. West of the 5 you are dealing with salt air and a marine layer that never lets the joint fully dry. East of the 15 it is heat, hard water and soil movement. We spec the job to the location rather than running one bead everywhere.

Local Conditions

What we see across San Diego.

The coast

La Jolla, Del Mar, Coronado, Encinitas, Solana Beach and Point Loma. Salt crystallises inside the bond line and breaks adhesion while the sealant still looks intact from above.

North county inland

Escondido, San Marcos, Vista, Poway and Rancho Bernardo get real summer heat and hard water, so the failure pattern looks much more like the Inland Empire than like the coast.

East county

El Cajon, Santee, La Mesa, Alpine and Ramona sit on moving soils at the foothill edge, where the deck and the shell settle on different schedules.

The estate communities

Rancho Santa Fe, Fairbanks Ranch and The Crosby have larger decks and longer joint runs, which means more linear feet and, occasionally, a two day job.

Before And After

A joint at the end of its life, next to its replacement.

From the coast through the inland valleys, San Diego County joints fail the same way: the bead hardens, cracks along its length, and pulls off the concrete on one side or both. These are a few of them, next to the joints that went in to replace them.

  • 01A bead cracked right through its length
  • 02Pulled off the concrete on both faces
  • 03The same joints after a full removal
  • 04A new bead, sanded and flush with the deck
