Deck Builder in Tiburon

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.
• A footing and framing inspection has to pass before any decking goes down, which is what sets the schedule more than the size of the deck does.
• Under the California Residential Code, a deck is generally exempt from permitting only when it is 200 square feet or smaller, no more than 30 inches above grade, freestanding, and not the required exit path from a door.
• The real tradeoff between wood and composite is the refinishing cycle and service life, not an upfront premium that has to be earned back.
• Most residential deck replacements finish in one to three weeks once permits clear.
• A deck attached to the house, or built more than 30 inches above grade, typically needs a permit and inspections.

How GVD builds decks

From low platforms off a back slider to elevated decks on steep lots, GVD Renovations handles deck design, permitting where required through the Town of Tiburon or Marin County, and construction in Tiburon. We are licensed (#989637) and carry liability and workers' compensation coverage. We also build decks in nearby Albany, San Pablo, and El Cerrito, and every design starts with a measurement of your grade and attachment point.

The first material decision on a new deck is which refinishing cycle you want to live with, because wood boards ask for periodic cleaning and resealing while composite and PVC boards trade that recurring work for a higher board cost up front. Choosing that cycle up front shapes both the board you buy and the maintenance calendar you keep for the life of the deck. GVD walks you through what each board class asks of you before we quote, so the number you approve reflects the upkeep you actually signed up for.

GVD runs decks the same way it runs its siding and window work: one dedicated project manager per job, its own carpenters, and a fixed-price scope agreed before construction starts.

What a deck costs in Tiburon

Two decks with the identical layout and railing are different projects when one sits on a flat lot and the other steps down a slope, because the sloped site adds taller posts, more footings, and framing that carries the change in grade. Knowing that the site sets the structural cost, not the floor plan you sketch, keeps your first call grounded in what the ground under the deck will actually require.

Most of a deck quote is framing, footings, and labor. The decking itself is the part homeowners think about and often not the largest line.

A budget near $5,000 covers a small ground-level pressure-treated deck under 100 square feet. Most projects are considerably larger than that.

For the full pricing breakdown, see our main decking page.

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

Every decking material trades something. Wood trades maintenance for a natural surface, composite trades a premium for a fixed cap, PVC trades more premium for maximum resistance.

Wood here means redwood, which is a premium natural material. Anyone comparing it against composite on the assumption that wood is cheaper is comparing against a product that is not on the list.

In Tiburon's marine air, moisture is the bigger concern than heat. Shaded corners and the north side of a deck can stay damp long enough to grow mildew on any surface, so board spacing, airflow under the frame, and a cleaning routine matter more here than board color. Capped composite and full PVC handle the damp better than wood.

Trex, TimberTech, and DuraLife

Treating all composite as one product is the mistake. Capped and uncapped, wood-core and full PVC, are meaningfully different things sold under overlapping names.

We install Trex's Transcend and Enhance lines, TimberTech and its AZEK full-PVC line, and DuraLife. There is no clear quality gap between the brands; they differ on color range, texture, railing and fastener systems, and price point. What does matter is capped composite (a wood-fiber core with a protective shell) versus full PVC (no wood at all, better moisture and stain resistance, higher price).

Do you need a permit to build a deck in Tiburon?

Whenever a deck attaches at a door or rises more than a couple of feet off the ground, assume a permit until the Town of Tiburon or Marin County confirms otherwise, since retroactive permitting costs more than filing at the outset.

Under the California Residential Code, a deck is generally exempt from permitting only when all of these hold: it is 200 square feet or smaller, no more than 30 inches above grade at any point, not attached to the house, and not serving as the required exit from a door. Once any one of those fails, which is common the moment a deck is attached at a slider or French door, the project needs a permit and inspections. Some jurisdictions add their own rules, so we confirm locally.

If your deck needs a permit, GVD handles the plan check submission and inspection scheduling with the Town of Tiburon or Marin County as part of the job.

Deck code requirements and inspections

A deck is one of the few residential structures where a code failure has immediate consequences, which is why the inspection sequence is as prescriptive as it is.

Code requirements for a deck focus on structure first (footings, ledger-to-rim-joist attachment, joist spacing for the board's span) and then on safety details: guardrails at 30 inches or more above grade, stair rise and run, and baluster spacing.

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

A second-story deck adds an engineering dimension to the project: the ledger has to carry more, and the footings have to go deeper.

Around Belveron and Lyford Cove, the site survey does more to set a deck budget than the material selection does.

Steep grades call for engineered footings poured to depth, a heavier-rated ledger connection, and code-height guardrails. The footing plan is drawn against the real slope of your lot, which is the detail that most often decides whether framing inspection passes the first time.

How we build your deck

Nothing in this order is a scheduling preference. Footings gate framing, framing gates decking, and inspections sit between them.

The steps cannot overlap much: nothing goes on top until the footings and framing are signed off.

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.

Allow for plan review up front when a permit is needed; its timing depends on the current queue. Elevated decks add days for footing work and inspections compared with a ground-level build.

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.

Having taken decks through the Town of Tiburon or Marin County plan review before, we know what inspectors check at the ledger, footings, and guardrails.
