Cost & Pricing

How much does a new deck cost in San Diego?

Pressure-treated wood: $25-$45 per square foot. Cedar or redwood: $35-$55 per square foot. Composite: $40-$70 per square foot. A 300-square-foot deck typically runs $9,000-$21,000. Height, railings, stairs, and footing depth drive the price. We confirm flat-rate after the on-site estimate.

Do you offer flat-rate pricing?

Yes. We quote flat-rate per project after the on-site estimate. The number we give you is the number on the invoice, with no surprise change orders for work we scoped in.

Is there an estimate fee?

The on-site estimate is free for new builds and deck repairs. We come out, measure, check the framing or grade, and put a flat-rate quote in your hands within a few business days.

Decking Materials

Should I build with composite or wood?

Composite (Trex, TimberTech) costs more up front but never needs staining and resists San Diego sun and coastal moisture for 25-plus years. Pressure-treated wood costs less but needs sealing every 2-3 years. Cedar and redwood look the best and weather gracefully but cost more than pressure-treated. We match the material to your budget and exposure.

Does composite decking get hot in the sun?

Yes, dark composite boards run hotter than wood in direct San Diego sun. We steer inland and west-facing decks toward lighter board colors and capped composite lines that are engineered to stay cooler underfoot. On coastal lots the marine layer keeps surface temps down.

How long does a deck last in San Diego?

A composite deck with properly flashed framing lasts 25-30 years. A pressure-treated wood deck lasts 15-20 years with regular sealing. Coastal salt air shortens fastener and connector life, so we spec stainless or coated hardware near the water. The framing, not the boards, usually decides a deck's lifespan.

Permits, Footings & Structure

Do I need a permit for a deck in San Diego?

Yes for any deck over 30 inches above grade, attached to the house, or covered by a roof or pergola with footings. Ground-level floating decks under 30 inches often do not. We pull the permit and schedule the footing and final inspections when the scope calls for it.

How deep do deck footings need to be?

San Diego County typically requires footings 12-18 inches deep on stable soil, deeper on expansive clay or fill. Hillside and elevated decks need engineered footings and sometimes caissons. We size footings to the load, the soil, and the inspector's requirements, never guesswork.

What causes most deck failures?

A poorly flashed or under-fastened ledger board where the deck attaches to the house is the number-one cause of deck collapse. Rotten posts, undersized footings, and corroded coastal fasteners follow. We treat the ledger, flashing, and connections as the most important part of the build.

How Our Referral Service Works

How does Deck Pro SD work?

You call us. We do a free on-site estimate, check the grade and framing, and put a flat-rate quote in your hands. If you sign, we assign a project manager and a vetted local crew that handles footings, framing, decking, railings, stairs, and permits.

Are you the crew, or do you sub everything out?

We are a referral and project management service. The crew on your job is a vetted local team that builds decks full-time, not a general handyman. We do the scope, scheduling, and quality control; they do the work.

How do I verify an insured contractor before signing?

Ask for a certificate of insurance naming you as an additional insured for the project duration. You can also verify any California contractor license at cslb.ca.gov by name or license number. We confirm insurance coverage on every crew before they are matched to a project.

What if I already have a contractor?

We are happy to share deck layouts, material schedules, and a written scope you can hand to a contractor of your choice. The estimate and scope are useful even if you never hire us to run the project.

Maintenance and Longevity

How do I maintain a composite deck?

Composite decks need very little maintenance. Sweep off debris regularly to prevent mold growth in shaded areas, and clean with a composite-approved cleaner once or twice a year. Do not use a pressure washer on full blast or harsh chemical cleaners. The boards themselves do not need sealing or staining, ever.

How often does a wood deck need to be sealed in San Diego?

Every two to three years is the standard interval. In direct inland sun the finish breaks down faster; in coastal shade it holds longer. Look for water that soaks in rather than beading on the surface as the sign the wood is ready to reseal. We can reseal an existing deck as part of a repair visit if you want a professional finish.

What is the best way to prevent deck rot in San Diego?

Three things matter most: proper ledger flashing so water does not infiltrate behind the ledger into the house framing, post bases elevated off concrete so the post end grain is not sitting in standing water, and board gaps sized correctly so water drains rather than pools. Most San Diego deck rot traces back to one of these three details being skipped at the original build.

Should I cover my deck in winter?

San Diego winters are mild and deck coverings are not typically necessary here the way they would be in wetter climates. What does matter is clearing debris from drain gaps and the ledger area after our brief winter rains, because organic material traps moisture against the framing. A quick inspection of the ledger flashing and post bases once a year is a better investment than a cover.
