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

"Quick and easy. I would highly recommend them."

"They were very prompt, friendly, professional, and very clean and worked very hard and did a great job on replacing our tankless water heater very ."

"We felt that Jared the tech and Billy and crew (installer) did a great job. Everyone was professional, timely and very good at what they did. We would/will hire again when needed."

"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!

"Excellent Service from planning through Execution and installation to final fine tuning. The folks communicated well and explained every detail of the step. Got permit and inspection done. It was seamless. Thanks. R."

"I'm very happy with the work that was done by Landmark construction and energy crew. At first, we met with Ron that came over and met with us about the issues that we had with our water heater and with the bills that we currently pay for electric. Ron recommended us to replace the bulky old water heater and to install a tankless system that will supply hot water immediately and with the use of less gas. We liked that idea and we decided to go for this project. Ron came over to our house with his 2 people that basically took care of all the removal and the installation of the new system. The work that they did took only 2 days from start to finish and now we have more space at the garage, and the bills are much lower than before…."

"Work was done on time and left area clean after the install.  Additional touch repairs were required after the installation and contractor had no problem returning to complete it to our satisfaction.  Great customer service, very informative and friendly staff and owner.

"Prompt, courteous and got the job done. Only disappointment is that my sink plug does not pop up to drain correctly all the time."

"The company was very professional and worked with me to get the optimum setup and value. Pricing slightly lower than competitors and delivery of energy in line with quote. I have had no problems with the install or product. Would highly recommend!"
