Deck Builder in San Ramon

Key Takeaways

• Capped composite has a wood-fiber core with a protective shell; full PVC has no wood content at all, which is what puts it in a higher price tier.
• On GVD's pricing a redwood deck costs more than a standard composite build, because the wood tier is redwood rather than pressure-treated pine.
• Every GVD quote is fixed-price and delivered as a detailed digital proposal before work starts, so the number approved is the number paid.
• Framing, footings, and railing cost roughly the same regardless of what decking goes on top, so the surface material drives most of the gap between two quotes.
• Most residential deck replacements finish in one to three weeks once permits clear.
• The real tradeoff between wood and composite is the refinishing cycle and service life, not an upfront premium that has to be earned back.

How GVD builds decks

GVD Renovations designs, permits, and builds decks in San Ramon, from ground-level backyard platforms to elevated decks on sloped lots. Where a permit is required, the work is reviewed and inspected by the City of San Ramon or Contra Costa County. GVD holds California contractor license #989637 and carries full liability and workers' compensation insurance. We also build decks in nearby Moraga, Dublin, and Castro Valley, and every design starts with a measurement of your grade and attachment point.

How the deck attaches to the house and how far the deck sits above grade are, along with size, the main facts that decide whether your project needs a permit, and neither shows in a rendering of the finished deck. GVD establishes the ledger attachment and the height above grade at the estimate, then quotes against what those measurements require. In San Ramon, the permit path may run through the City of San Ramon or Contra Costa County depending on where the work falls.

A deck is a structural project wearing a finish product, and the part that decides whether it lasts is the framing and the ledger rather than the boards on top.

What a deck costs in San Ramon

Height above grade sets footing depth, the structural support the frame needs, whether a guardrail is required, and the permit path, all at once, which is why a deck a few feet higher can cost meaningfully more than one close to the ground. Knowing that this single measurement drives all four before you call keeps the estimate conversation grounded in your actual conditions.

Getting the structural scope right at the estimate is what makes a fixed price possible, since the largest unknowns on a deck are below the decking.

If the budget is the binding constraint, the entry point is around $5,000 for a small ground-level pressure-treated deck under 100 square feet.

Our main decking page walks through pricing in more detail.

Two quotes for the same footprint usually differ mainly on the surface material, since the framing, footings, and railing underneath carry a similar base cost. What pushes an elevated or second-story deck higher is the deeper footing work and added structure.

Wood, composite, and PVC compared

Material choice on a deck is a maintenance-commitment decision. Homeowners who will not refinish on a cycle should not specify wood, whatever the price.

If the reason for considering wood is budget, the pricing above suggests reconsidering, since composite comes in below it and needs no refinishing cycle.

In San Ramon's hot, sunny summers, color is a comfort decision as much as a design one. Composite and PVC absorb radiant heat, so a dark board in full afternoon sun runs noticeably warmer underfoot than a light one. Manufacturers publish comparative surface-temperature data by color; ask to see it for the line you are considering, and consider a lighter color or shade for the sunniest exposure.

Trex, TimberTech, and DuraLife

Brand matters less on decking than most marketing suggests, and construction type matters more.

GVD installs Trex (including the Transcend and Enhance lines), TimberTech (including its AZEK full-PVC line), and DuraLife. Between them, the practical differences are color and texture, railing and hidden-fastener systems, and where a line sits on price. The bigger decision is construction: capped composite has a wood-fiber core under a protective cap, while full PVC has no wood content at all, which makes it the strongest option against moisture and staining and puts it in a higher price tier.

Do you need a permit to build a deck in San Ramon?

Whether a deck needs a permit turns on how it attaches and how high it sits. A low, freestanding platform sometimes falls outside the requirement; an attached or elevated deck typically does not. The City of San Ramon or Contra Costa County makes that call.

The state exemption is narrow: a detached deck of 200 square feet or less, no more than 30 inches above grade, that is not serving as a required exit. Most decks attached to a house, larger than that, or built higher need a permit and inspections, and local amendments can be stricter.

When a permit is required, we draw the plans, submit them to the City of San Ramon or Contra Costa County, and schedule each inspection ourselves.

Deck code requirements and inspections

Most of what code requires on a deck is invisible in the finished product, which is exactly why the inspection stages are sequenced the way they are.

California's residential code covers footing depth and bearing, ledger attachment to the house rim joist, joist spacing rated for the decking material's span, and guardrails for any walking surface 30 inches or more above grade. Stair rise and run and baluster spacing are checked at final inspection.

Inspections usually happen at the footing stage, again at framing and ledger attachment, and at final. Improperly lapped ledger flashing is one of the more common reasons a deck fails an inspection, so we flash it to the manufacturer's specification during framing.

Elevated and second-story decks

On a lot where the ground falls away from the house, the deck becomes a framed structure carrying real load rather than a platform sitting on the yard.

Level lots take straightforward footings and a simple permit path; sloping lots need engineered footings and more inspection stages.

When the ground falls away steeply, the deck becomes a true structure: deeper engineered footings, a ledger rated for more load, and full-height guardrails. We design the footing layout for the measured slope, not a flat-lot spacing template.

How we build your deck

The six stages below are the same on every deck job. What varies is how long permitting takes and what the grade requires at the footings.

Footings and framing gate everything after them, so the schedule follows the inspections rather than the other way around.

How long a deck takes to build

Plan on one to three weeks of construction for most deck replacements, with permitting as a separate stage before crews mobilize.

Plan check timing is the biggest unknown before construction starts. Once building begins, elevated and second-story decks take longer than ground-level ones because of deeper footings and more inspections.

Maintaining your deck

Composite is often sold as maintenance-free. Refinishing-free is the accurate version, and it is still the main reason homeowners choose it.
