"Kirk was able to correct both of my plumbing issues very quickly...a faucet that had very little water coming out and a slow draining sink. He also checked the water pressure at the front of the house..it is a bit high so we are going to decide the next step on this. I am always pleased at the communication from Valley Plumbing and most of all I am pleased with Kirk's professionalism, courtesy and skill in solving my problems. Highly recommended. I felt the price was fair and appreciated the senior discount."

"Oak called 2nd but came next day/ UN-prepared to do either repair or water test (requested on phone) or even replace with ready new ADA toilet that the lying receptionist booker said they have “some in stock and if not he will show a catalog of choices”. Guy came punctually with Nzo tools or appliances Or knowledge of what I asked for as an “URGENT repair/replace”. See ABC review same call. Not quite as bad as them doing same since we also still have broken HVAC too, both said they would fix ( I bought gasket already, they could have put in) or replace if they brought new toilet. Problem is not in water pipes except they need testing for lead - both said they would do this too - when I asked oak re taking a sample, how long sitting in pipes? He wiped off his soda water bottle and asked “which pipes?” !!"

"Can not imagine a better response, starting with my call for assistance, response time and how the technician, Tad methodically diagnosed the problem. We have an obscure kitchen fixture that required service in Feb 2019. Under warranty the problem was easily diagnosed by me, a problem possibly caused by me and a replacement part sent and installed by Albert Nahman team. Problem: I broke the faucet cartridge. Current Problem: restricted hot water flow in this kitchen sink only. Turns out the new cartridge part is now malfunctioning. I called and Tad arrived taking a step by step approach ruling out possible causes: a clog here or there, build up of sediment, or blockage in the lines or cartridge. The company that sells the product got on the phone with Tad and they collaborated on the problem and the tech person gave Tad one more thing to try. After the collaboration it is agreed, problem persisted and therefore that new cartridge part is now malfunctioning and will be shipped free of charge in two days. Thanks to all, who made this possible and I trust we will have Tad here again soon to finalize this fix. BTW, cost of service was less than expected given going rates for such a call lasting in excess of one hour. Another comment, spending time with Tad during the repair was a pleasure to have him explain, collaborate, listen and just chat. Questions on who to call next time, no question who I will call next time. I have read criticism of costs: In the Berkeley area "How much does it cost to hire a plumber? Some plumbers have a minimum fee for a service call. They might charge anywhere from $175-250 to come out and give you a consultation. Plumbers may give you a general service rate of $128-148 per hour when there are a lot of unknowns about a project and they aren't sure how long it will take. Some charge a flat rate for their plumbing services. For example, you may get charged $175 for a sink or drain cleaning, while toilet installation costs $500." Today costs are upfront, same as charges in Feb, $69 to arrive and assess the problem. Here in excess of one hour for $129 minus $25 coupon, total charge $173. I am ok and I expected these costs. If I was in Philly, where I grew up, I could call an uncle or cousin and get a better rate, a family rate. This is going rate for our area."

"I feel that I was very lucky have chosen Corsa Plumbing to do diagnose and replace 2 sewers for me. One in Lafayette and one in Pleasant Hill. Ray, was easy to work with and he did a great job of advising me on the existing problems and explaining what they would do to fix them. The camera inspection of the sewer line and the estimate were free. I was present when he did them. Both of the bids were fair, but do not include the cost of County permits. I will highly recommend you get a bid from Corsa Plumbing. You won’t regret it. You can hardly tell that the sewer was replaced Steve Walsh, retired Realtor and property manager for residential homes."
