Highly recommended.

A couple of weeks ago, I called Don Nichols Plumbing in a panic when my tankless water heater…read moresuddenly stopped producing hot water. Even though his schedule was already full that day, Don made the time to come out between appointments and quickly fixed the issue. When I asked what the emergency visit would cost, he simply said, "Don't worry about it--just call us to schedule your water heater service." Since my system was due for service, I went ahead and scheduled it. They did a fantastic job, taking the time to fully flush and descale the unit and remove mineral buildup. Everyone I interacted with--from start to finish--was incredibly nice, down-to-earth, and genuinely pleasant to work with. I won't hesitate to use Don Nichols Plumbing again and highly recommend them.

After checking the City of Santa Rosa website, I found BG Backflow and reached out. Bryan got back to me right away -- he texted a few questions and, within two hours, sent over a clear and professional proposal. My test was already past due since I never received the first notice, but Bryan understood the situation and fit me into his schedule the very next day. He took care of everything quickly and professionally. The communication, customer service, and his expertise in backflow testing were outstanding. I highly recommend Bryan and BG Backflow. Great job, and I'll definitely be reaching out again next year!

It took him about 20-25'. The technician was skilled, polite and efficient. I wrote them a check, but I was not given a written estimate, nor was I given a receipt. NO itemized information on the charges at all. It seemed like a lot of money!!! I called the secretary later that afternoon and she had the owner call me back. He listened to my concerns and we arrived at a compromise. So, just be informed of the charges beforehand and get multiple estimates if you can. Copperfield Plumbing is a reputable and flexible business and a good choice if your due diligence is complete.

She said her Hot Water Heater…read morewas making a loud knocking sound & the Company who installed it was scheduled to do a maintenance drain & flush a couple days ago but called to say they were understaffed & she needed to reschedule. Well she needed it taken care of now! So, I Googled Plumbing places and started getting quotes. Advanced Plumbing was by far the Best business for her Plumbing needs. No sooner did I hand up with making an appointment, the doorbell rang & there they were Advanced Plumbing employees Jamal & Terrance. They assessed the issue & provided my mom with the best & most affordable solution. They were very friendly, knowledgeable, & fast. They explained what they would be doing, showed her the damaged parts that they were replacing & had it done in no time. They also explained to her about the Warrantee on her product & about all the benefits her new Advanced Plumbing Membership offered. So we would definitely recommend Advanced Plumbing in Vacaville to anyone looking for affordable, friendly, & fast professional work done. Also a Big Thank You again to Jamal & Terrance for your Great Work !!

!!PLEASE READ FIRST!!…read more I should have shopped around instead of rushing into hiring this company, that's my biggest mistake. I recently had a new washer and dryer installed, and the installer told me my water valves were leaking and needed to be replaced. This was the first company I called because of their high number of reviews, which I now regret trusting. The price I was charged to replace those valves was outrageous--nearly $1,100, and they didn't even bother to repair or replace the sheetrock afterward. For such a basic job, that alone felt excessive. It gets worse. After doing just one load of laundry, my water heater on the second floor started leaking down into the first floor. This had NEVER happened before they worked on my plumbing. I called them immediately, but they couldn't send anyone out until the next day. When a technician finally arrived, I was quoted $4,000 to replace the water heater. That didn't sit right with me, so I decided to get a second opinion. I contacted another company, and the difference was unbelievable. They charged me $2,300 for the same water heater replacement, showed up within an hour of my call, and completed the entire job in about two hours. Out of curiosity, I also asked them what they would have charged to replace the laundry room valves. Their answer? Around $350. So I was charged nearly three times the going rate for a simple repair, and then quoted almost double for the water heater replacement. That's not just overpriced, that feels completely PREDATORY. I strongly recommend getting multiple quotes before hiring anyone, especially this company. I would not use them again and would not recommend them to anyone.
