“REI Plumbing did a great job installing a new 40 gal water heater and removing my old tankless unit.”
REI Plumbing did a great job installing a new 40 gal water heater and removing my old tankless unit. Prompt communications and quote submission made the job go very smoothly. Installers Justin and Miguel were on time and efficient. I highly recommend plumbing services by REI.

Honest hard working company, today he sent his assistant to get the device to run my line, asked “how long it’s been out.” Answering “a week” he ran scolding water charging me zero for his extra time in saving me $150. Original estimate was solid too, not like a huge one asking for thousands

“Look no further for a trusty plumber!”
Look no further for a trusty plumber!. I was referred to REI by my neighbor and I can't say it enough of what a relief it was to finally find a plumber who I could trust and doesn't tax every.... single.... thing.... Donal's crew did a great job with the installation of my new water heater. A lot of these other companies have so many higher ups that need to get their money that it ends up costing SO much money. This is where you need a family owned business. Believe the other reviews on here!

“There was a leak in my downstairs neighbor's bathroom ceiling.”
There was a leak in my downstairs neighbor's bathroom ceiling. I called yesterday afternoon, and first thing this morning, I had a plumber. He was able to quickly identify the issue and fix it. Although fixing the toilet addressed the issue, he did check to make sure the sink and shower were not creating an issue. I hope I don't need a plumber again, but I will call REI Plumbing if I do.

“My partner and I had been getting price quotes to replace our 50 gallon water heater and contacted 4 plumbing companies.”
My partner and I had been getting price quotes to replace our 50 gallon water heater and contacted 4 plumbing companies. We received quotes that were astronomical and knew that the upfront cost would be expensive however enter REI Plumbing and Donal Reilly. He could not have been more professional in answering our questions and never ever did he use any sales tactics. We received a price quote with a breakdown of what would be done and immediately knew we would be having REI do the work. Carlos 1 and Carlos 2 showed up exactly on time and were very nice and showed care and concern for our home and keeping things neat and tidy. They did such a great job on the installation and with the copper pipe installed it looks like a work of art. We can't begin to thank Donal, and both Carlos 1 and Carlos 2 for such a great job!! Do yourself a favor if you are looking for price quotes and call the team at REI because you won't regret it!! We now have a plumber we trust and won't hesitate to call anytime we need work done.
