Priced by region, not nationally
Your ZIP decides the rate. Sacramento and the Bay Area are different markets and we do not pretend otherwise.

Built from 2026 California cost data
Material and labour ranges for this state, adjusted for the size, finish level and scope you choose.
3
A range — and we show all of it
Low, likely and high. A single number would be easier to read and less honest.
4
The real price comes from a site visit

Your rights as a California homeowner
- This is an estimate, not a bid. The range above is generated from regional cost data. It is not an offer, a bid or a contract, and nothing on this page binds either side. A real price comes from a site visit and arrives in writing.
- A home improvement contract must be in writing. In California any home improvement job over $500 has to be a written contract, signed before work starts, listing the scope, the price and the payment schedule (B&P Code §7159).
- Your deposit is capped by law. A contractor may not take a down payment larger than $1,000 or 10% of the contract price — whichever is smaller — and progress payments may never run ahead of the work completed (B&P Code §7159.5).
- You have three business days to cancel. You may cancel a signed home improvement contract within three business days, and within five business days if you are 65 or older. The written cancellation notice comes with the contract.
- Check the licence before you hire — anyone. Every California contractor working on a job over $500 must be licensed. Verify us, and anyone else bidding, at cslb.ca.gov or on 800-321-CSLB (2752).
