Sundeck Construction San Marcos
Sundeck construction in San Marcos lives at the intersection of structure, shade, and material choice. Hillside coastal influence — morning marine layer, warm afternoons, and salt-tinged air on west-facing elevations in San Elijo Hills. Pick the wrong decking color near Cal State San Marcos and the surface temperature hits 140 F on a 95 F day — unusable without shoes.
Why San Marcos homes need a different sundeck construction spec
What we find on San Marcos deck calls: original redwood from the '90s that's cupped or splintered; over-garage sundecks leaking at the ledger flashing; and second-story wood decks the homeowner wants to rebuild in composite without shutting down the lower room. Every one gets a framing inspection before we quote the decking spec.
Products we install for sundeck construction in San Marcos
Deck product stack for San Marcos: surface is Trex Transcend, TimberTech Azek, or Fiberon Concordia composite; railing is aluminum picket (Fortress, Westbury) or stainless cable for ocean-view elevations; framing is pressure-treated SPF or Douglas fir with Simpson galvanized hardware. Color choice matters — we spec lighter "driftwood" and "sand" tones in San Marcos because dark boards surface-temp above 140 F on west-facing decks.
