    Trenchless sewer line replacement using the pipe burst method via the DitchWitch machine is an alternative to complete sewer line excavation.

    A new pipe is laid as a bursting head busts up the old pipe, feeding through the new pipe in it’s place. Compared to lining, replacement by the pipe burst method will work on pipes that are in much worse shape. Avoid total excavation, and completely tearing up your yard, and landscaping.


    “We were surprised by “no hot water” and needed a new water heater late on a Friday.  Called Bay Area Plumbing and Ron arrived within two hours ready to go!  He removed the old and installed a high quality replacement in record time.  Ron also fixed the safety strap which was done incorrectly 15 years ago!  Highly recommend Ron at BAP…for quick and professional service.  He’s our new “go to” for any plumbing jobs.”


    Pleasant Hill, CA

    “I called them and someone picked up the phone right away, I told him the situation and he told me that he will send someone over as soon as possible. Soon enough around 45 minutes later, Ron shows up. He is really nice and friendly. He explained me to what happened and gave me an estimated cost. The price is fair and I agreed to that. Ronald had it fixed really quick, I could tell he is really experienced and knows exactly what he is doing”


    Pleasant Hill, CA

    “Ron and his company have helped me in some very tight situations and always saved the day!  Most recently today he squeezed me in and cleared plugged drains in short order.  Ron is always very professional, on time and just what you’d hope for with his plumbing service.  I highly recommend him.”


    Concord, CA

    “We spent hours trying to fix the leak ourselves. Around 3am we had no running water, a small lake under our home and were in a panic of what to do. At 7 a.m. I called Ron who not only answered the phone but was at my home by 8am. He was friendly, calm and knowledgeable. He had our problems addressed and under control.”


    San Ramon, CA

    “We are a three time customer of Ron’s Bay Area Plumbing.  They were key to a major bathroom redesign/remodel, came back to do another minor project for us, and just did a new water heater install for us. We have received nothing but excellent service and results at a reasonable price from Bay Area Plumbing.”


    Walnut Creek, CA

    “I have used Bay Area Plumbing multiple times over the years. The last two times were for a new water heater last year and having my main line cleared this year. Each time Ron and his crew have been professional and efficient. They show up on time, they do the job quickly and they charge me what we agreed to.”


    San Francisco, CA

    “Our water heater broke and started leaking all over our kitchen late on a Tuesday night and I was able to get in contact with Ron even though it was extremely late. He was able to give me a quote right then and there and was also able to make it out to install a new water heater the next morning”


    Walnut Creek, CA

    “I am a landlord that owns a few rental properties. I used to rely on a home warranty company to deal with tenant plumbing issues until they proved totally unreliable and useless. Now I use Bay Area Plumbing (BAPS) Inc. to respond to residential plumbing issues. They respond promptly, arrive on time, address the issue with professional skill and are outta there in a jiffy.”

    “I am very happy with the service provided by this company. The tech was able to clear a washing machine drain, kitchen sink drain, install new drains in the bathroom and change two faucets. He was polite, clean and cleaned up after himself. The company took a credit card so the whole process was quick and convenient. I am recommending this company to my friends.”
