"Unfortunately there was a defective fitting that caused a pipe to burst. The house was vacant so we didn't learn about it until the next day. Alvin bent over backwards to repaire the damage, replace the ruined water heater, and make us whole. He even changed the water heater to a tankless model because the location of the ruined water heater didn't meet code and tankless was our only option."

"100% recommend. Very professional in every way as the other reviews say. Geremias and his nephews installed a tankless water heater for me, and it works great. Punctual, responsive, communicative, trustworthy, and the best price. I couldnâ t ask for better."

"I had Glover Plumbing Solutions replace my old yucky tub with a Delta rainforest Walkin Shower, as well as my old tank water heater with a Navien 240A2 tankless water heater and recirculation system. Ryan did a great job with the installation and made sure everything met California code requirements. The workmanship was excellent, everything was tested before he left. Im beyond thrilled he gave me the bathroom of my dreams and im hard to please. I seriously recommend this young man."

"Main line root clog. Late evening call to request service the following morning for a root issue in Main line. Needed to be hydro jet due to the liner put in a few years prior. ( side note..NOT done by this company and didn't hold. Expensive and would replace with new pipe for same cost.) Expedient service and video verification . Would Definitely recommend this company. This became my new plumber and I am on yearly maintenece schedule for this property. Thank you Juan."

"I stared to look for a plumber after I found water under my water heater. I jumped on Angi and posted my issue. With in minutes....Art messaged me and said he can be her 1st thing in the morning. BTW. This was 10pm at night. His quick response was a plus for me. I had one other respond but he over extended himself to my need. He came at 7amd and said....you need a new water heater. I can got get one and install it now. I was a bit reluctant and he said call me when your ready and left. My wife said his prices looked fair and he seemed like a good plumber. I called him back and said lets dance. He was back at my home in a hour and 1/2...and started the work. He protected my carpet and placed plastic on it. He warned my that maybe the cost might go up due to the age of the pipes and valves. He had the old one out and the new one in an an hour or so. He was quick, clean and polite. I paid him and shuck his hand. I recommend Art for your household plumbing needs. He was excellent."

"Being a nice guy and feeling ripped off by a contractor is two very different things. We chose Michael Howard based on his response time , being personable and reviews. He's a very nice guy but in the end felt ripped off. We found that our initial interactions was very pleasant. He couldn?t determine with his assistant or figure the problem of our central heating unit and then told us we needed to replace the entire electrical circuit board. Cost was $750. He replaced the board and it still didn't solve the issue of heating up. He then determined that it was the motor that was the issue. Additional cost to repair $400. What was frustrating was that after speaking with other reliable sources while the job was taking place I asked Michael Howard for the old circuit board. He claimed that I told him to discard it. Not true at all. It was a red flag when a contractor is making up a story and calling me a home owner a liar. Why would I tell a contractor to throw out any parts until the job was solved and completes ? That truly concerns me as a home owner. Why would a professional discard the old circuit board fir the entire heating system before the job was finished ? My neighbor who's a contractor wanted to review the old circuit board. Then a day later Michael Howard returned with parts for the motor. He insisted and needed a confirmation of payment before he would repair the motor. Wanted me to sign an agreement when I questioned his judgement and concern that he might have replaced a circuit board that was perfectly fine since he later discovered the motor issue. I went up into the attic and found the old board. I asked him to now try the old board that I found discarded in the attic ( same part he claimed was discarded ). He told me that once he put in the new board it would be impossible to return it to the supplier that he purchased it from. Even with several hours of purchasing it. I asked him to show me a receipt and that I would call the vender. He refused. Ok so he didn't want to show me the receipt. When I looked up the part on line it sells for $90. So his mark up is 600%. I understand the time and labor but it was not very long. He then told me he would not charge the $400 for the parts for the motor. Wow. Bottom line is that when we later replaced the old board to test it , it worked fine. The real issue was the motor. The fact that he didn't want to make the effort to return it to the supplier with 24 hours is because he wanted to make the money. Clearly. Willing to not charge for the motor parts doesn't make me feel any better. Just made me recognize how much I was being ripped off. . And doesn't give the confidence to ever use this contractor again or recommend him regardless of all the terrific reviews."

Dutton Plumbing, Cooling, Heating & Electrical runs out of two locations, one in Simi Valley and one in Sylmar. We’ve been working out of this valley since 1987. From those two shops, we cover Ventura County, the San Fernando Valley, Santa Clarita, and Northern Los Angeles County. That’s plumbing, drain and sewer, water heaters, HVAC, and electrical, all handled by the same crews. Nearly four decades in the same region adds up. Our crews have been inside enough houses out here to recognize what a given neighborhood tends to do before they open anything up. Post-war ranch homes behave one way, newer builds behave differently, and we’ve seen it all.
