Get matched with top tankless water heater installers in Zamora, CA

"Great service!! This company knows the plumbing business; and our toliet was perfectly installed."

"You be crazy not to hire this guy and his brother! They were professional courteous and friendly. Would recommend to everyone to do business with these guys and trust them with your water heater installation and I think you’ll find the price more than reasonable and fair."

"SG Quality Builders was the last of 5 different pros we took estimates from. SGQB seemed to be the most knowledgeable and had the expertise to do a complete job installing our new tankless water heater. Because of how our existing water heater was plumbed, installing our tankless was more difficult than most. Serge took the time to explain how the installation would be completed and answered all my questions. The installation was completed as planned including the permit and inspections also handled by SGQB. SGQB did many steps to minimize the disruption to our daily routine and did the little things like covering our carpet when they worked inside the house. The water heater works great. We would definitely invite this pro for future projects."

"They were efficient. Clean. And they worked with my budget for what I needed. I lost my husband in July and he usually handled the outsourcing of these type if things. It's nice to know I can do it alone."

"Gustav was polite, knowledgeable and explained what needed to be done to fix the issue."

"The tech that came to my home was the best out there. If you want any plumbing issue done right the first time, this is the place. Ask for Jeff; they don't come any better"

"Very well. Matt arrived on time. Actually discovered a leak in my wall and helped open it up as well as installing the tankless water heater."

"Went very well. Nick was professional and courteous."

"Original estimate and proposal was handled in professional manner. Everything was fully explained and there was no pressure or "snow job". Everything was itemized and put in writing. The "free" hot water heater was not needed so received a credit of $1300.
The five man crew arrived on schedule and got to work immediately.  Met with supervisor Mark and foreman Jose and reviewed job.
The crew laid down tarps for dirt control (looked good at first, but wasn't that effective. Attic insulation was still tracked in house  They did attempt to vacuum everything up.)
Crew didn't have a ladder so they used mine. No big deal.
They all worked really hard and there was no loafing around. Had the walls opened and new pipe laid out and ready to go the first day.They didn't hesitate in working late. Made the ordeal of having to have a re-pipe bearable. It was great to still have water all day and that night.
The crew were very polite and friendly and we enjoyed their presence.
They really appreciated the free lunch we gave them and helped cement our relationship. They all deserved a "Gold Star" for their outstanding work.
The next day layout was completed, old pipe removed and new tied in. New piping was flushed and  pressure tested. No leaks.
As a former building inspector, I was very impressed by their professionalism, work ethics and attitude. It's very rare to have someone "do it right the first time".The following day the drywall came and repaired all the walls that had been demo'd. Outstanding job.
 Only a few negatives:
Cleanup. 
Attic insulation that had been pushed aside was not put back.(still not done)
They also missed some shock absorbers which the building inspector caught. Jose came back the next day and took care of the them.  Bathroom exhaust fan had been stepped on and pushed down below the ceiling. Drywall man attempted repairs. OK..
Piping could have been flushed a little longer to get all debris out. Minor.
Overall I am very pleased with the work. Price was a big OUCH!
UPDATE!
It has been several months now and I find the installation was not as great as I thought.  Rather than moving the ceiling insulation, they installed the pipes on the roof rafters. Pipe insulation inadequate; water too cold in winter and scalding hot in summer. Don't let them take short cut!
