""Project: Remove existing gas hot water tank, replace with new, install new per current city code. Zeb and his team were professional, on time, fairly priced and tidy (so clean we didn't even know they had been here). Also, when the city inspector came, he was very impressed by their skilled installation and attention to detail. And, on top of all that - Zeb's is a local company!"

"If there was an event for Team Plumbing in the Olympic Games I'd enter Chad Micheal's Professional Plumbing. They just completed a very tough job for me and did it in an impressive manner. I asked Chad to replace a sewer line from our home to our septic tank. We live on the side of a hill and the septic tank to serve the lower floor is 8 feet deep. That means a trench starting at about 5 feet and ending at close to 10 to get down below the septic tank entry plumbing. Five guys showed up at our house right on time and went on the attack to dig in the rock hard decomposed granite. It was like watching a ballet. Each team member clearly knew exactly what needed to be done and how to do it. The cooperation with each other and the anticipation of and preparing for the next move was remarkable. Chad did the final hook up to the house and tank himself. I have no idea how he could get that done down in a trench 10 feet deep with the walls literally at shoulder width. He passed the PVC pipe and fittings up and down with the surface crew for trimming or adjustment until he was satisfied everything lined up exactly right. Outstanding! Naturally the Team had a couple of the normal unforeseen curve balls thrown that they had to deal with. As it neared the end of the day Chad said to me, "Don't worry it will be hooked up in a temporary configuration so you'll have full indoor plumbing tonight." And we did as the Team completed the final elements using flash lights and a drop light! At 8:36 they announced competition and we could flush the toilets again. No one will ever set foot on our property with a pipe wrench other than Chad Micheal's Professional Plumbing. They are now our "Go To" guys and I recommend them without reservation."

"Jacob is knowledgeable and efficient, he really understands how to customize the job to fit your needs. He brought our poorly installed water heater up to code and made repairs, and also discovered a c02 leak and took care of that, so we are especially glad we hired him when we did! Thank you Jacob for being a trustworthy and friendly contractor."

"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…."

"Well-equipped to complete the job. Dominic explained the options thoroughly and clearly, then performed the work expertly. On the high end of the range price-wise but all things considered it was worth it for the peace of mind of knowing it was a job well done. I would recommend RF Plumbing."
