Why San Diego Homeowners Are Ditching Real Wood
Redwood and pressure-treated lumber warp, splinter, and rot quickly under coastal moisture cycles. Homeowners spend $1,000+ every two years stripping and staining wood decks. Advanced capped composite and cellular PVC decking delivers the warm aesthetic of exotic hardwood (like Ipe or Teak) with 30-to-50-year manufacturer fade and stain warranties.
Hillside Canyon Deck Engineering & Caisson Footings
Many of the most dramatic decks in Del Mar and La Jolla hang over steep 40-degree canyon slopes. Building over a canyon requires structural engineering plans stamped by a California PE, soil geotechnical borings, and drilling 18-to-24-inch diameter reinforced concrete caissons 10 to 20 feet deep into bedrock to withstand lateral seismic loads.
