Choosing a Patio Cover Contractor in Brentwood, CA
Two bids for the same patio cover can be thousands of dollars apart and both be honest, because they describe different jobs. This page is the checklist for comparing them: what a complete bid includes, what to ask, and the red flags. When you're ready, we'll pass your request to an independent local contractor.
Cited cost ranges · No obligation
What usually makes bids hard to compare
Different roofs
One bid prices lattice, another insulated solid. Make every bid name the panel.
Permit in or out
Some include drawings, engineering and the city fee; some leave you to pull the permit.
Footings and attachment
How deep, how wide, and how it ties into the house are what plan check reviews and what holds it up in wind.
Electrical and demolition
Lights, fans, motors and removing an old cover are often separate lines, or left out.

How this site works
Brentwood Patio Covers is an independent referral site, not a contractor. When you call or send a request, it goes to an independent local patio cover contractor who serves your area. That contractor gives the quote, pulls the permit if it's in their scope, and does the work. You're never obligated to hire anyone, and you should compare more than one bid.
What a complete bid includes
- Dimensions: width, projection and height, plus a simple drawing.
- The structure: attached, freestanding or wall-mounted; post count and size.
- The roof, by product name: solid, lattice, insulated or louvered, and the panel or blade model.
- Footings: size, depth and whether new concrete piers are poured.
- Attachment: ledger on the wall or tie-in at the eave, and how it's flashed against leaks.
- Engineering and drawings, and who prepares them.
- The permit: who pulls it, whether the city fee is included, and that the job won't start without it.
- Drainage: gutters, downspouts and where the water goes.
- Electrical: lights, fans, heaters, motors, outlets, and who runs the circuit.
- Demolition and haul-away of any old cover.
- Schedule, payment schedule and deposit, in writing.
- Warranty: what the manufacturer covers and what the installer covers.
- The contractor's license number, on the bid.
Questions worth asking
- Have you built covers in my city, and do you handle the plan check?
- What happens if the plan checker asks for bigger footings or a different attachment?
- Is my eave strong enough to tie into, or does this need a ledger or its own posts?
- How will this affect the light in the room behind it?
- If I add lights or a fan later, can the roof carry the wiring?
- Who do I call if a panel leaks or a motor fails in year three?
Red flags
- Offers to skip the permit to save money. In Brentwood a patio cover needs one, and an unpermitted cover can come up when you sell.
- No drawing, no footing detail, no product names.
- A large deposit or cash-only terms.
- A license number that doesn't match the business name, or none at all.
Check any contractor's license
California contractors are licensed by the Contractors State License Board. Look up any contractor by name or license number at cslb.ca.gov (opens in a new tab) and check that the license is active and the business name matches the bid. The CSLB site also has consumer guidance on home improvement contracts and payments; read it before you sign.
For prices to check bids against, see the patio cover and pergola cost guide. For the permit, see Brentwood permit rules.
Check any contractor, including one you find here
- Ask for the contractor's CSLB license number and look it up at cslb.ca.gov. The CSLB site also explains when a California contractor license is required.
- Get the quote in writing, naming the size, the product line and roof type, the footings, who pulls the permit, and the warranty terms.
- Be wary of large deposits or cash-only terms. Ask who pulls the permit, and what happens if the city or the HOA asks for changes.
- Ask whether engineering and plans are included, and get HOA approval in writing before you sign a start date.

How many bids should I get?
At least two or three, and make sure each one names the same roof type, size and attachment so you're comparing the same job.
