"Very honest, trustworthy and inexpensive plumbing company. I had three total estimates for the work and the other two companies just seem to want to charge as much as possible and do more work then was needed. I highly recommend Western Rooter and ask for Ryan, he’s the best!"

"The plumber spent a lot of time just trying to figure out the source of the hidden leak. He had a lot of patience. The quality of work was good as was the price. I would definitely hire them again."

"There was leak in my laundry wall..that seems to come and go. I can not figure out where it is coming from. . I called several plumbers to get their opinion and quote. Several plumbers came and gave their opinion and quote. All of them stated that they need to use leak detection methods because they don't know where the leak is, it will be an extra charge once I agree to hire them. All the plumber gave me a quote based on what I told them. they but did not really do anything before hand . Luckilly Andrew from Service Flow came and I told him the issue and he took his time to diagnose where the leak could be coming from, he even performed an initial moisture detection in thevwhole house and other techniques to find out where the leak is..he really took his time to diagnose the issue and found the issue without an initial charge. He gave me a very good quote. I hired Service Flow because of the care and concern that Andrew showed, great customer service and very affordable."

"We’ve had so many plumbing projects over the years and have always used Rapid Rescue. They have replaced our water heater, completely plumbed two bathrooms & worked on the house mainline as well as the gas line and hooking up the water lines for the washer & dryer. They are honest, reliable and affordable. The work they have done has been top notch and it lasts. I highly recommend Wes and Rapid Rescue for all of your plumbing needs."
