Good work at a reasonable price. I like dealing with an owner operator. He lived up to my expectations.

Derek Webb has been a plumber for 2-3 decades. Knows what he's doing, is more than fair, and is pleasant to deal with. I've a sewage ejector pump (you don't want one - really) that he has worked on twice in the last 20 years. I just hope he doesn't retire before I have the whole house fixed. :-) read more

I had a great experience with this plumber! He was professional, reliable, honest and very skilled in his trade--everything you hope to find in a plumber! Derek showed up on time for both the day of the estimate and for the day of his services. His estimate matched the final cost (NO bait-N-switching), and he throurouly explained everything he did. Need a plumber? This one is definitely one to hire! Sorry to hear someone else had"racial" issues; I'm a "minority" and did NOT have ANY racial issues with this person. read more

Derek is a true professional that is extremely knowledgeable in all aspects of plumbing. He will get the job done and solve all plumbing issues. I have to say his services have come in handy for several different properties over the years. read more

Derek has been my plumber for many years. He's a professional and a gentlemen. Derek goes above and beyond when he does repairs. He also offers suggestions to avoid future repairs and issues. Plus, he doesn't talk down to me like some repairmen. Just because I'm blonde and a girl doesn't mean I don't know about home repairs ;) His quotes are always fair and he guarantees his work. If you are looking for a good honest plumber Derek is your guy! read more

This guy is fantastic...no-nonsense and gets right to the diagnosis and addresses problem. It took him minutes to figure out what was going on with a toilet/pipeline blockage in our home...and he came prepared with equipment in his truck. Not only did he fix the problem, but he also advised us on our piping system and made some recommendations to prevent future issues. Very intuitive and experienced, honest professional who is NOT looking to gouge you in an emergency situation. Highly recommended!! read more

Mr. Webb did substandard work. He had to be taken to small claims court, where he lost. He lied to the judge about what he did, and what he said. Avoid at all costs. read more

Derek saved our butts and got a complicated pump job done ahead of the holidays. And, though it's hard to believe, he charged us $10,000 less than our original quote from a company out of Concord. Great dude too. read more

Derek has been to our house a few times for minor plumbing work and we had no issues. On one visit he found a bigger issue that needed to be fixed. He gave us an estimate for 1/2 day job and told us if it took him less time he would charge less. In the end it took just under 3 hours, but he had to go under the house for one pipe. He failed to tell us there was a flat $250 fee for that. And our crawl space is 4+ft! Even with the cash discount the end price was more expensive than the original estimate, and when you figure the cost of parts ($90), $250 to go under the house (which should have been discounted I think given it was so much bigger than a normal crawl space), and 3 hours of labor I still don't come close to the fee he charged (off by ~$300). I liked the guy and he did a good job with the work, but very disappointed with the price. read more

My old water heater decided it was time to retire and leaked out so I replaced it with a tankless. Shameless plug for my awesome plumber. I called Derek on Sunday and after a 5 hr install on Monday I had hot water again! Derek got me a Noritz tankless that was only $2300 vs the others that r $4000 because they require all kinds of extra retrofitting venting etc. The tankless water heater will save me money on my gas bill so will eventually pay for its self. Maybe a couple hundred a year. Can ur old standard tank water heater do that? D Webb plumbing (925) 944-5152 Good luck! read more

I called Derek at 8am on a Sunday while it was pouring outside to fix a sump pump issue. He came by on time the same day and fixed the problem quickly and efficiently for a great price. read more

Thanks to D. Webb for providing such fine, honest, and prompt service! I called D. Webb on a Friday at 9pm, and he was at our house by 9:30pm. He then quickly diagnosed the problem (and didn't even say that what I did was sooo stupid!) and went to work, in a very quick and efficient manner...but not before giving us an estimate on the time, and the cost. He was done in an hour, as he had estimated, then proceeded to clean the area up. He took a couple of minutes to advise us of preventive measures that we could take to avoid a recurring problem. We use D. Webb's services at the office building where I work, so I knew that they were very reliable and safe. I felt very confident calling them from the start...and now that is reinforced. read more

The best plumber. Used for numerous jobs for my interior design clients and my own house.

Derek is a one-person shop. He is very personable and professional, experienced and knowledgeable. He came highly recommended by a friend, and did not disappoint. I called at 1:45 PM, and he arrived just after 2:30. We needed to have a replacement disposal installed. By phone, Derek advised maybe an hour to do. When he arrived and assessed, he thought maybe 1.25 hours. Turned out he did not have to remove and replace certain piping, and he completed the job in 50-55 minutes. His $120 hourly rate was competitive with other places. Accepted payment form is cash or check, no credit cards. Derek determined that the original disposal was not installed correctly, although that did not affect the actual need for replacement. The replaced unit was a Badger 5 by Insinkerator, which is widely panned by users on the web (for cracked plastic cylinders) and which Derek considers a low-end product (sold by Home Depot). Chat with Derek indicated he is well-connected with a recognizable local supply firm and he considers himself to be one of the best plumbers in Contra Costa County. He named 2-3 that were on my list of possibles, and considered one as not measuring-up to high marks by the Yelp community. On leaving, he assisted gratuitously with something unrelated that had been bothersome for several years. Plumbing is a touchy-feely thing. Often, one doesn't know how good or bad a plumber is until long after the fact. Given the plaudits my friend gave, plus my experience with him, Derek will be my plumber of choice in the future. read more

Derek Webb is the best Plumber I have known over the last 15 years... honest, knowledgeable, and reliable. He also takes care of our business plumbing and can handle any size job. read more

All around great guy! Derek helped us out in an emergency situation at night when our main water supply broke a few years ago. Since then he's been back to replace an old shower valve and install a new gas line to move our stove. Every time he was helpful, professional, and friendly. Thanks Derek! read more

Derek was available on 24 hour notice - came on a Sunday, and replaced our kitchen faucet. No fuss, no feathers, neat and clean, in and out in 30 minutes. What a guy! read more

"Quick and good" is Derek's motto, and he delivered! We had two old sump pumps that we wanted to replace in case El Nino arrives with a lot of rain (we hope). Derek sized up our situation and made recommendations; everything he said made sense, so we agreed to go forward with him. He picked up the pumps and supplies at a local plumbing store, came back, and completed the work. Everything looks good, and now we're ready for our electrician to upgrade the system. Derek told us that because he has taken classes with the pump company, he can add a year to the warranty. Summary: our project was completed the same day, in a professional manner, and for less than the estimated price. Thank you to yelp for helping us find D. Webb Plumbing. read more

Just moved into a new house and need the gas dryer installed. Webb Plumbing was called on Saturday evening and was at the house Sunday at 9am and hooked the dryer and went above and beyond to review plumbing and gas features throughout the house. Excellent and Prompt Service one of the best I have ever used. Nice job. read more

D Webb is a honest hard working contractor. We had a recent house fire that required rebuilding a portion of our home and plumbing repairs consisting of installing new supply and drain lines. D Webb performed good work, was honest, a good communicator and professional throughout the job. He understands the concept of customer/client relationship and always had our best interest in mind. It was such a relief dealing with an honest contractor. read more

Derek was the only plumber who agreed to come out in a timely manner to investigate and work on a major leak that induced me to shut off my water, and he did not charge an exorbitant overtime charge because it happened to be on a Saturday. He is clearly very intelligent, a good communicator, skilled, experienced, and very strong and energetic with a work ethic seldom seen these days. When I thought I had a similar leak, and called him out again, he showed me that a lever was slightly out of position, and only charged me gas money for the service call. My son also used him a number of months ago to install a new water heater and do some other remodeling plumbing jobs and was pleased with his work. Bonus - he is nice to your dogs and seems like an all-round great guy. read more

Substandard work and difficult to work with. Made promises before work started and then refused to do what he had agreed to. Had to fight with him daily to get things done right. He consistently looked for the easy way out rather than doing the job correctly. His resistance escalated as the job went on and his mistakes surfaced. This also resulted in his installing fixtures incorrectly and haphazardly. There is nothing worse than a passive aggressive plumber. Avoid at all costs. read more
