Deck Builder in Brentwood

Key Takeaways

• One project manager coordinates scheduling and inspections for the life of the project, from the first measurement through final sign-off.
• 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.
• 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.
• 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.
• Every GVD quote is fixed-price and delivered as a detailed digital proposal before work starts, so the number approved is the number paid.
• The real tradeoff between wood and composite is the refinishing cycle and service life, not an upfront premium that has to be earned back.

What a GVD deck project covers

From low platforms off a back slider to raised decks off upper-floor doors, GVD Renovations handles deck design, permitting where required through the City of Brentwood or Contra Costa County, and construction in Brentwood. We are licensed (#989637) and carry liability and workers' compensation coverage. We also build decks in nearby Antioch, Clayton, and Pittsburg, and every design starts with a measurement of your grade and attachment point.

Whether your deck attaches to the house and how far its surface sits above grade are, along with size, the main facts that decide the permit path, and neither shows up in a finished-deck photo. GVD measures height above grade and inspects the attachment point at the estimate, so the permit question is answered before you commit. When a permit is required, GVD handles the permitting process with the City of Brentwood or Contra Costa County.

The work is managed in-house end to end, which is what keeps the schedule and the inspection sequence under our control rather than a supplier's.

What a deck costs in Brentwood

The deck material you choose is a maintenance commitment as much as a purchase, and on our pricing the redwood tier sits above standard composite, which changes what you sign up for over the years, not just at the quote. Knowing that a wood surface asks for periodic sealing while composite asks for far less keeps the material conversation about how you want to spend future weekends rather than only about the opening number.

The attachment decision, freestanding or ledger-attached, changes the permit path and the framing at the same time, which is why it gets settled first.

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

A decking material has to survive full sun, standing water, and foot traffic simultaneously, which narrows the field faster than the aesthetic conversation does.

A pressure-treated deck is genuinely the budget option and sits below all of these tiers. Redwood is not, and conflating the two is the most common mistake in a decking conversation.

In Brentwood'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

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 Brentwood?

If the deck attaches to the house or sits more than 30 inches above grade, expect the City of Brentwood or Contra Costa County to require a permit and inspections. A low freestanding structure may not trigger one.

A deck typically skips permitting only if it is freestanding, 200 square feet or smaller, no more than 30 inches above grade, and not the required exit from a door. Attach it to the house, build it larger, or build it higher, and it generally needs a permit and inspections.

GVD prepares the plans, submits for plan check, and schedules the inspections with the City of Brentwood or Contra Costa County when a permit applies, so you are not tracking down a separate expediter.

Deck code requirements and inspections

The parts of a deck an inspector cares most about are the parts a homeowner never sees once the boards go down.

The framing rules cover the parts you will not see: footing depth and bearing, how the ledger attaches to the house rim joist, and joist spacing matched to the decking's rated span. Guardrails are required at 30 inches or more above grade, and stair geometry and baluster spacing are checked at final.

A deck is typically inspected at two or three points: footings before they are covered, framing and ledger attachment, and a final once decking, railing, and stairs are complete. Ledger flashing is a common reason for a return trip, because the house's weather-resistive barrier has to lap correctly over the ledger, so GVD flashes it to manufacturer specification on the first pass.

Elevated and second-story decks

Where the drop is significant, stairs and landings become part of the structure rather than an accessory to it, and they carry their own code requirements.

Around Shadow Lakes and Brentwood Country Club, the site survey does more to set a deck budget than the material selection does.

A lot where the grade drops away from the house faster than a ground-level deck can follow needs an elevated or second-story structure: engineered footings poured to depth, a ledger connection rated for the added load, and guardrails at full code height. GVD lays out footings against the actual slope rather than a standard flat-lot pattern, which is often what separates a deck that passes framing inspection from one that does not.

How we build your deck

This is the standard sequence across the trade. A contractor proposing to reorder it should be able to say exactly why.

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

A typical deck replacement runs one to three weeks on site. Where a specific project lands depends more on the structure below than on the square footage above.

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

The maintenance case for composite is real and worth stating precisely: no sanding, no staining, no sealing. Cleaning still applies.

Why Brentwood homeowners hire GVD Renovations

We have worked through plan review with the City of Brentwood or Contra Costa County and neighboring jurisdictions, so when a permit is required our submittals match what inspectors expect.
