"First, I called Vista Plumbing for an estimate. Ray, the plumber, listened to our concerns and explained what he could do to help with the rattling problem with the pipes and the hot/cold situation in the shower.  He gave me a number for the part needed (under warranty) and asked me to call when the part was received.  Next, when the part was delivered, a time was arranged and Vista Plumbing was here within the week.  In one day the water pipes were clamped and the shower faucet was replaced.  Now, everything concerning the water pipes are good.

I was happy with the service, the knowledge, the expertise, the punctuality, and the kindness.  In the beginning, he spent a lot of time listening to our concerns and answering our questions.  In the end, I received a clean, professional job.  I would recommend Vista Plumbing to my friends and family.

I also would like to mention the woman who answers the telephone and makes the appointments.  She was wonderful and helpful, very upbeat.  It was a pleasant experience talking with her."

"Scott Fanatizzo was our plumber. First he turned off the water going to all the toilets. Then went outside to check the pressure valve to the house. It was not working and the pressure coming through the house was the same (121) as from the city to the house. After installing a new pressure valve outside, he checked all the toilets inside and found that only one needed the inners replaced. Problem solved. Scott was polite, neat and efficient! He called and left a voice message alerting me that he would be early, plus I received an email from the company telling the name of the plumber that would be doing the work along with his picture. Awesome customer service!! Great company!!"

"Had our old tank water heater replaced with a tankless model and had a whole house water filter installed at the same time. We had only a vague idea of what we wanted when we started and they were able to help us flesh out our plans without making us feel foolish for not knowing every detail (which wildly some of the other bidders did). They were able to come out fast and did good work, would hire them again in the future."

"Gus at Pro Bright went above and beyond on a Sunday to detect and repair our master bedroom ceiling leak. With water to the house turned off at the street we were desperate to find a contractor who could respond right away. Other contractors offered appointments Monday or Tuesday. Gus responded that he could be here in 2 hours to repair the leaking pipe, but could have Jeff, his water mitigation project manager here within 30 minutes to assess the water damage. These guys were both so professional. They shared the process, timeline and costs, and were prepared to start right away. They promptly moved my disabled husband and his adjustable bed to another room away from the work area assuring his comfort and safety. Gus repaired the overhead leak and turned the water back on. Jeff scheduled the water mitigation process to begin first thing Monday morning. We are especially grateful for the kindness these 2 professionals showed us in our time of need."

"We had a hot spot on the floor and a high gas bill last month leading us to suspect a slab leak. We called several plumbing services and Personal Plumbing was able to come out the next day with their own slab leak tech. The techs were on time and took about three hours to find the leak and reroute and place pipe to repair. They were able to avoid more holes in the drywall by placing the pipe on the exterior garage side, extending us savings. They also showed great integrity by letting us know that any repair would also have to replace factory pressure valve that was no longer working (putting pressure on our system). We will definitely keep them in mind for any other plumbing work we need done!"

"When I first talked to Al he walked me through some items to see if I could do the repair myself. Once we figured out the level of the repair needed he immediately came over the next morning. By noon that day he had replaced my water heater, brought it up to code and charged a very fair amount. He also removed lines and capped them that were no longer in use that was not related to the water heater replacement. Al is old school and I very much appreciated his honesty as well as trying to work through the problem. Two other companies, they remain anonymous but both are on TV, came out and didn't look at the water repair heater to repair but just gave me an extremely high cost to replace. I have found my "go to" plumber. Thank you Al1"
