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.

Brandon was able to come the same day to clear clean out. Great work and competitive prices.read more

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!

I had Copperfield Plumbing out to fix a copper water pipe that was leaking (March 2026). I never…read moretalked prices with them. I was quoted $380 by the repairman after he looked at the problem. 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.

I purchased a walk-in tub in Jan 2024 and Eco Plumbing was going to install. took until May to get…read moreit installed. when they removed old tub I had to do subfloor repair. this tub is advertised as having two access doors to do any repairs on tub front. One of my two drain handle controls quit working a couple months ago. I final got around to calling Ella's Bubbles company to find out about repair. I was instructed to notify company that installed. I called Brandon at Eco Plumbing and a few days later two of his workers came to figure out problem. I was informed the subfloor would need to be cut into from below to access cable to drain stopper and new cable approx $100 not counting install. I said no to floor hole cutting as company states this should be accessed through access door in front of tub. This visit cost me $350 for nothing! I will be putting formal complaints with company.
