Delphi Construction

Delphi Construction is a Deck Builder, Construction Company, and Waterproofing Service serving San Diego, known for custom decks, outdoor living spaces, and structural repair. Schedule a free on-site consultation to review design options, permitting, and materials (pressure-treated, hardwoods, or low-maintenance composites) and request a clear, itemized estimate. If you have balconies or roof decks, ask about their waterproofing systems—membranes, coatings, proper flashing, and drainage—as well as warranty coverage and maintenance plans. For a smooth build, confirm they handle HOA/city approvals, get a detailed project timeline with milestones, and request recent local references and photos of similar projects before you commit.
