"Thank you to Geremi and GMC plumbing for all your hard work. They replaced all my pipes, my tub, toilets, faucets and fixtures, my hot water heater and the casing that houses it and they re-dug the sewer line. All this for a very reasonable price and they could not have been any more courteous and professional. Highly recommend this licensed plumber for any project that you have."

"They called us quickly and got a plumber out within a few days. Super thorough - tested all pipes and water sources to diagnose the problem. They were able to perform maintenance on most bathrooms the same day and improve the water temperature in our showers. Gave helpful, non-biased advice on potential further plumbing improvements. We will likely call this company again for any and all future plumbing needs."

"Rubio’s Plumbing service is by far the most professional experience you will ever have when it comes to trouble shooting, repair, or a new & complete repiping service. I have used Rubio’s on a number of occasions and each one has exceeded my expectations by far. I have had my home water service repiped without any issues. This was a huge undertaking that was performed quickly and without water disruptions. I have called them back during a remodel to change my laundry service location, both natural gas and water hookup that went smoothly. Rubios Plumbing also installed a bathroom vanity with the necessary plumbing upgrades which included faucet and sink fixtures. Their service was so incredibly reasonable in price and the quality of service was very professional. Rubios takes pride in their work and the cleanup afterwards. They provide recommendations to minimize future plumbing issues, forecasting recommendations to keep things in working order. Additionally, I called them once again to remove my old gas water heater and replace it with a Tankless Water Heater. A suitable location was found and the demo & installation process was completed once again with very positive results and no issues whatsoever. I could go on and on about how well they are but the bottom lines is, They were affordable and always worked within my budget. Rubios is a local company making it more convenient with a timely response to tackle any immediate problems. I highly recommend this company and I will certainly be calling them once again for my future home addition project coming up soon. I can truthfully say they are honest and trustworthy while working with the highest level of Customer Service, Integrity and Customer Satisfaction. You don’t need to spend a lot of time getting bids and waiting for other plumbers to show up or trying to upsell you. Call Rubio’s Plumbing and know that you’ve made the right call without all the hassle of those overpriced and over advertised out of area plumbing services. Support your local businesses with Rubios Plumbing, trust me, You’ll Be Glad You Did!"

"After speaking with Kevin (CEO) about the merits of the One Water System, and my own online followup, I bit, and was scheduled for installation 5 days later. Juan, the installer was on time, courteous, self-effacing, humorous, knowledgable and highly skilled. He replaced the ugly functioning plumbing (piping) with a more contoured professional appearance. After the system instalation, function test, old water softener packed and area cleaned. I was given an outline of positives results to look for.  And, as of 2 weeks after installation, I am very pleased with results. Faucet run faster, wife says hair and skin feels better. Good professional results from beginning to end.

"Setting up the appointment was easy. They offered to come out the next day but I needed to wait until Friday, my day off. Mike showed up on time. Did a good professional job removing and installing a new 50 gallon water heater. Mike also tested my water pressure and noted it was too high. For an agreed upon small additional charge he replaced my pressure regulator and a shut off valve."

"Art was extremely helpful and accommodating at every step of the project, from bidding through scheduling and even some additional work we needed a few weeks later. The team worked efficiently, doing a new main line install (going under our sidewalk and concrete without any demolition), re-piped the horizontal pipes under the house with copper (they were 100 year old galvanized), and setup a new shut off and regulator outside. They did everything in a day and cleaned up nicely. When we had other contractors working on our foundation 2 weeks later, they bent over backwards to get plumbers out the next day to make some fixes to drain pipe and at an excellent price. I got quotes from three companies and Repipe Pro was the most competitive and also great responsiveness from Art and his wife Thelma who run the business. To anyone looking for a repipe of a home or new main line or having drain work done, I definitely recommend contacting Art at Repipe Pro."
