"I received a lower price than the other two brands we got bids from and the installation was well done. I did not want to buy a water softener online and install it myself as I knew some plumbing would have to be done so I was willing to pay more to have an experienced person perform the installation."

"Perfect! I called Western Rooter the AM my disposal went out. They were at the house the same day, at the time they stated they would arrive. The work was done efficiently and professionally and completed within an hour. I have called on Western Rooter for many years for various plumbing needs (clogged drains, replace water-heater, replace main water line, etc.) and have always had great, timely service at reasonable $$$."

"CARP is top-notch. Our water heater crashed, and we had no hot water. Number 1: Gaddiel gave me an estimate immediately based on pictures. Number 2: Jose and Ivan arrived the same afternoon and replaced my water heater. I couldn't be more grateful."

"Can not say enough positive things about this company. Usually do alot of things diy, but i would hire them any time to do plumbing. Their professionalism is way above board. Prices more than fair. Miguel is a definite asset to this company. When i have a plumbing problem i will definitely call them back. (had another company come before them that could not get the job done and suggested replacing the trap under my bathtub. My home is not on a foundation but a slab, and that means removal of my bathtub. The cost of his visit would have gone from one hundred dollars to thousands. ) Thank you Service Champions!"
