Check the license
Every plumbing contractor in California needs a C-36 license from the Contractors State License Board. Ask for the number and look it up at cslb.ca.gov. The record shows whether the license is active, bonded, and clear of complaints. One Hour Plumbing Service is CSLB #992029.
Read the reviews for specifics
Star counts are easy to inflate. Read the text. Reviews that mention the city, the job, and the price being what was quoted tell you more than a hundred five-star ratings with no words. Look at Google and Yelp both, and look at how the plumber answers the bad ones.
Ask whether the estimate is free
Some companies charge a trip fee just to look, then apply pressure once they are in your house. Ask up front. A plumber who is confident in their pricing will give you a number over the phone for common jobs, or come out and look at no charge for the ones that need it.
Watch for the upsell
The most common complaint about big plumbing chains is being told a small problem needs a big fix. A snake job becomes hydro jetting. A clog becomes a sewer replacement. If a quote feels high, get a second opinion before signing. A good local plumber will tell you when the cheaper fix is the right one.
Questions worth asking on the call
Five questions, two minutes:
- Who is coming out, the owner or a subcontractor?
- Is the estimate free, and will the price change without my OK?
- Is the work warrantied, and for how long?
- Are you licensed and bonded, and what is the number?
- When can you actually be here?
