Another great service with Liam

I hate to sound redundant but Liam just keeps impressing us. An innovative, independent thinker he can come up with correct solutions to my requests. It's refreshing to see. Please don't lose him. Also, Caleb is well on his way also, he could not done any better that being pared with Liam. I can't thank you guys enough for the help we have received during this kitchen reno project. Having excellent, reliable people that I can count on is so helpful as 20 year old home renovation is rather stressful. Thanks again

Excellent & Dependable Service

Austin Newman is a trustworthy plumber. During the coldest days this winter, our water heater broke down and we only had bone chilling cold water. Austin took care of calling Rheem to order the needed parts. He prioritized us in his schedule and when the needed part arrived at their company, he promptly installed it the following morning. Now we have hot water again! I highly recommend TE Certified for reliable plumbing and HVAC repairs.

Upon arrival and approval, we began previously quoted work of replacing the Roman tub faucet. The customer was not able to get a hold of the trim for the Roman tub faucet but he was able to locate the faucet rough. The faucet rough was the component of the faucet that had failed. In order to gain access to the necessary plumbing, we cut out the side of the cabinet next to the tub and were able to gain access to the plumbing through there. We installed to isolation valves underneath the tub surround so the Roman tub faucet could be isolated if needed. After installing the new rough and reinstalling the trim, we tested everything for leaks and proper function. No further issues at this time

For this job, I worked on performing electrical panel maintenance and adding whole house surge protection. As a courtesy, I rerouted circuits to the generator connected panel.

Came out for leak in the yard. At&t ran their machine over lawn, in the process they tore up the irrigation line and main domestic lines. Both were broken causing water to leak up from underneath lawn (left side of house). Temporary domestic line was installed and irrigation line capped off on both ends. Did notify customer of the temporary line and connections. There is no warranty on line due to line being too shallow, tech advised customer to run faucets during and temperature drop below freezing, to help from freezing. Turned on n water supply, tested with no leaks at this time.
