"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."

"We chose BeastBay Plumbing for a complete home repipe after meeting with several companies. Ron Buris and Jovon were professional and promised great service, which is why we hired them. I requested the work be permitted. The crew worked hard, but cleanup could have been better. Unfortunately, the day after the job was completed, a newly installed pipe behind our chimney leaked, soaking our brick fireplace. They repaired it, but it leaked again a couple of days later, causing more water damage. We had to shut off our water and went without water until Monday because no technician was available Sunday. I was told someone would bring fans to dry the area, but no one came, so I rented them myself. The city later failed the inspection, requiring additional corrections. We paid quite a bit for this project. After final payment, communication became very poor. I expected better follow-up and accountability for a job of this size."

"The services we received from Oak Plumbing was FANTASTIC from the customer service (the ladies that answered the phones), to the Technicians. The quote/price for the repairs was very reasonable, as will as quick service. One of the things that I really appreciate was that both the technician that can to give the quote, and the technician that can to do the repairs both respected COVID Protocol including fresh booties for their shoes. Oak Plumbing will be my go-to plumbers for all my plumbing needs."

"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."

"Great service and quick. Plumber was very knowledgeable. Only negative was the appointment schedule. I was told between 1pm and 2pm but the plumber didn t arrive until 4pm. I think the dispatcher or owner needs to work on how to schedule clients. Plumber for me has no fault in that."
