How to Find Good Plumbers in Contra Costa County 


Plumbers in Contra Costa County are required to be licensed by the State of California, such as with the C36 license specifically for plumbing which legally allows them to construct or connect on-site waste disposal systems, piping, storage tanks and venting for gasses or liquids, all flues and gas connections, water and gas piping from utility meter to the building, installation of equipment for hot water including solar powered, maintenance and replacement of all previous items also including gas earthquake valves, gas control valves, back flow preventors, and regulating valves.

If the plumbing company has employees, they are legally required to have workers' compensation insurance to protect you the customer from being sued or having a claim against your property insurance in the event an injury occurs during work performed on your property. Plumbing contractors are not legally required to have general liability insurance, but all plumbing companies bearing The Prime Buyer's Report—TOP 10 designation do have that general liability insurance coverage which reimburses you in the event of any damages, in addition to passing all other requirements for Prime Buyer's Report—TOP 10 status such as phone calls to previous clients, hiring only documented workers, verified license and workers' comp insurance, clean complaint record, and more.

Good Plumbers in Walnut Creek, Pittsburg, San Ramon and Richmond CA Perform Numerous Services
The best plumbers in Contra Costa County are capable of much more than fixing leaky faucets or a clogged toilet. They are required to be adept at all aspects of piping, connections, and waste disposal systems in your home. Basically, the plumbers handle anything that moves, removes, stores, or controls the temperature of gas or liquid.

With such a wide range of required expertise, it's understandable that some plumbers in Contra Costa County specialize. Some are commercial plumbers in Contra Costa County and others specialize in plumbing for new construction. Fortunately, you can still find good plumbing companies in Contra Costa County by the specific service specialty you need.

General plumbers in Contra Costa County have experience doing leak detection and leak repair, and fixture replacements. Plumbers also unclog drains and pipes with Hydroscrub jetting or other high powered jetting systems, which they can then outfit with backflow prevention systems. But if you need resolution to a more complicated plumbing problem, the best plumbers in Contra Costa County can locate and perform video inspection of water lines and attend to underground plumbing issues. 

In addition to the actual labor, some plumbing companies are willing to offer their expert knowledge to other household issues. Specially trained, AWWA plumbers (American Water Works Association) are equipped to deal with escrow inspections, propane and natural gas leaks, and gas line installation. Master plumbers in Contra Costa County are federally licensed plumbers, serious professionals with sound business practices and expansive industry knowledge.


Plumbers for Repiping in Contra Costa County
Repiping is the replacement of all existing water piping with brand new pipes. Repiping in Contra Costa County is often done to improve hot water delivery, permanently solve plumbing leak problems, or solve the problem of low water pressure. When repiping in Contra Costa County, ask the plumbers about choices in pipe materials to repipe with. Many plumbers recommend repiping in copper as a safe, strong material that resists corrosion and carries warranties. There are different grades of copper piping however, so ask the plumbing companies to be specific in their repiping bids.


Low Water Pressure Problem
Plumbers in Contra Costa County can help you solve a low water pressure problem. Low water pressure can be due to something simple like sediment that is clogging a showerhead, or the removable aerator on a sink faucet, in which case unscrewing them off and cleaning them may be all that is needed.  But low water pressure can also be due to something more serious like restricted water flow in your main water line due to a kink, deposit build-up or clogs. A faulty water pressure relief valve can also cause low water pressure.   Plumbers can install two water pressure gauges, one on either side of your pressure relief valve (or pressure reduction valve) to determine the water pressure coming into your home from the city water main, or your well, and then compare that to the gauge measurement of the water coming out of your pressure valve to determine if the water pressure relief valve or pressure reduction valve is at fault.

Sometimes low water pressure is simply due to geography.  If your water is supplied by the city, compare your water pressure to that at other homes on your street. It may be that if your home is on a hill, or close to a municipal water tower, that low water pressure is not due to your plumbing but is endemic to the neighborhood.  If your water comes from a well, that may also be the reason for your low water pressure. In both instances, plumbers can install a water pressure booster pump to solve your low water pressure problem.

Questions to Ask Plumbers in Contra Costa County 

When choosing which plumber to hire, ask the right questions about their experience, range of services, credentials, and methods and materials before deciding.

• How long have the plumbing companies been plumbers in Contra Costa County?

• How many plumbing jobs have the plumbing companies completed in Contra Costa County?

• Can they give you customer names and numbers you can call as references? (All plumbing companies bearing the Prime Buyer's Report—TOP 10 symbol have already had customer references called by research staff at The Prime Buyer's Report so you don't have to.)    

• Do the plumbers have experience with the type of plumbing repair work you've described?

• How long should it take for the plumbers to solve your plumbing problem?

• Will the plumbers be able to complete the plumbing repair work in a single visit?

•  Can they prove that all their workers sent to your property are legally allowed to work in the U.S.? (All plumbing companies in Contra Costa County bearing The Prime Buyer's Report—TOP 10 symbol have already signed an agreement to only hire documented workers.)    

• • Does the plumbing contractor have active workers' compensation and general liability insurance for your protection? (All plumbing contractors in Contra Costa County bearing the Prime Buyer's Report—TOP 10 symbol have already shown proof of insurance to research staff at The Prime Buyer's Report.) 

• Do they charge for plumbing estimates?

• What type of warranty do the plumbers provide? What plumbing services does it cover?

• Does the owner (the licensed plumbing contractors) do the work or do they send employees to do it?

• Will the plumbers in Contra Costa County provide a written contract?

• Do the plumbers charge by the job (flat rate) or by the hour (time & materials)?

Once you've got answers to these questions, you're ready to review their bid.  Price should rarely be the determining factor since cheap plumbers in Contra Costa County usually aren't the best ones and it can cost you more to repair or replace their faulty work or inadequate repair than if you chose the best plumbing company to begin with.

When you've chosen the best plumbing company in Contra Costa County for your specific needs and priorities, make sure they are still licensed in good standing with a C36 license for plumbing contractors in Contra Costa County CA.
