"I highly recommend the company (Costello's Plumbing) as well as the employee who helped us (Miguel). My wife spoke with Mr. Costello this morning, and booked an appointment for Miguel (one of his workers) to come over and look at the situation / prepare an estimate. He did so (arriving iwihin the appointment window), gave us a good quote, and indicated the two parts that needed replacement (the garbage disposal unit and the cold water dual shut-off valve. He indicated that we could purchase those parts through the company, or if I had the parts onhand, he could just install them (saving money). Fortunately, The Home Depot nearby was open, and I was able to get the two pieces fairly quickly. Miguel then: * installed the garbage disposal (and took care of getting rid of the old one), * connected the replacement shut-off valve, * replaced the faucet itself, and made sure that none of it leaked. A job well done!"

"Leo did a very extensive plumbing repair that required digging through my bathroom floor and replacing a huge pipe to the outside. He also prepared and installed piping and fixtures for a bathroom remodel. Always showed up when he said he would and had a great crew. Cleaned up as well. Would highly recommend."

"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."

"Pedro Galvan replaced my garbage disposal. He was prompt (always a plus to me, as I've experienced delays without phone calls in the past), he worked quickly and efficiently and removed the old garbage disposal. He is an excellent resource."

"Replaced a filing water heater. The work was excellent. My water heater was basically blocked in by the incoming water and gas pipes, but the two-person team managed to remove the old heater, replace pipes as necessary, and get everything working again. Gave up-front pricing including permit inspection. Super professional crew."
