"My hot water heater went out. I called several plumbers and was being quoted astronomical amounts along with quite a wait time to get to me. Brice was able to get the job done quickly (since no hot water sucks) and at a price I could live with. He was super funny and professional and made me feel like a friend had come over to help. I will always call him first for any of my plumbing needs "

"I appreciated the quick service I got from Roto Rooter, a couple other listed plumbers couldn't get to me for a week or so. Chris came out the same day, replaced my defunct garbage disposal, and removed a leaky whole house filter. He was efficient and very professional. I was a bit taken aback by the price, but then again, haven't had any plumbing done in a long time, so figured it's probably standard! I would hire them again definitely. Sure did not want to wait a week with a non-functional sink."

"My tankless water heater was not installed properly by a friend who was helping me out. James and team came in and took care of making it safe! They also have repaired a leaking faucet. I love having someone come out on time and do the job right the first time. I?ll only use Authority Plumbing and Drain. Plus my network depends on me for referrals and I can refer James and his team with 100% confidence."

"Parker's Plumbing technician was a fine example of how the company does business. Was prompt, very patient in explaining what he was doing and in and out just as fast. I will be asking for them again with any future projects. Five stars well deserved!"

"We had a severely reduced flow in our kitchen faucet. The plumber came out and removed some plastic debris (probably from something that broke in the pipe) and the flow was back to normal. The following day it was restricted again, but they came out the same day, and removed more debris for no charge, calling it warranty service. Impressed. Will call again."

"I am afraid to be too honest because Mike will never have time for us!! For the 35 years we have lived in our home I would rank Mike as the best professional we have ever hired. He has unclogged drains, emergency sub-pump repair, and replaced pipes , faucets and toilets. He is competent, on time, honest and a really nice person. You will never regret choosing Mike. "
