Deck & Porch Construction
Custom decks and porches designed for your yard, your view, and the Bay Area climate
A premium take on deck & porch construction
A new deck is the fastest way to add living space to a Bay Area home, and the easiest project to get wrong. Slopes, fog, salt air, and strict building codes all punish shortcuts. ISMA Builders starts every build at the foundation: footings sized for your soil and slope, hardware rated for coastal moisture, and framing laid out to millimeter tolerances before the first board goes down. From a compact Sunset District platform to a multi-level Burlingame deck with built-in seating, we design around how you actually want to use the space, then build it to outlast the fog.
This service is a good fit for homeowners and property managers who want a clean, professional result without juggling the details themselves. We handle the prep, the finish work, and the cleanup so the space is ready to enjoy when we're done.
Every project covers the essentials
- Custom design matched to your yard, slope, and sun exposure
- Footings and framing engineered for hillside and coastal conditions
- Coastal-rated hardware, fasteners, and joist protection on every build
- Cedar, redwood, composite, and hardwood options with honest trade-offs
- Permits and inspections handled with your local building department
- Written workmanship warranty on the finished deck
Four steps from first call to final walkthrough
Design & Site Visit
We walk the space, measure slope and access, talk through how you'll use it, and sketch a layout with real material options and prices.
Written Scope & Permits
An itemized estimate with a start date and a finish date, and we file the permit drawings with your local building department.
The Build
Footings, framing, decking, and railings in the right order, with the site contained and cleaned up at the end of every day.
Walkthrough
Every board, railing, and stair checked with you before the final invoice — and we come back if anything isn't right.
