San Mateo Decks & Patios.
San Mateo's R1 lots run an efficient plan check by Peninsula standards — costs are driven by land and labor, not process.

San Mateo cost band — 2026
$9K – $32K
San Mateo sits in our Peninsula / Westside tier (Tier 5) — typical projects land inside this band when scope is locked before mobilization. The main cost drivers on a San Mateo decks & patios project are scope size, finish level, structural and MEP touchpoints, and any permit overlays on the parcel, and the $9K–$32K band assumes those are sized to the lot, not upgraded mid-build.

- What's specific to San Mateo that affects this project?

- Is decks & patios in San Mateo a good investment vs. moving?
- For most San Mateo owners, yes — the $9K – $32K spend usually beats a 6% commission + transfer tax + buying-up-the-block, and Prop 13 keeps your tax base intact. We share comparable-cost analysis in the first walk so you can decide before signing anything.
- Why is decks & patios more expensive in San Mateo than inland CA?
- Three reasons: (1) licensed-trade labor runs 30–55% higher than the Inland Empire or Central Valley, (2) San Mateo Building Division plan-check and inspection fees are higher and slower, and (3) staging/parking constraints on small lots add real cost. The $9K – $32K band reflects all three baked in.

- One-year workmanship warranty on everything we install, plus the manufacturer warranty on every product (typically 10–25 years on roofing, 25 years on HVAC, lifetime on cabinetry hardware). Warranty service is in-house — same crew comes back if anything needs attention.

- Yes — at least three past clients per scope, ideally in San Mateo or an adjacent city in San Mateo County. We share addresses (with owner permission), final invoices vs. signed contract, and the punch-list close-out doc so you can verify how the project actually finished.
