"Excellent service. Ray called ahead of appointment to confirm model requirements. He found that a leak was starting. I trust his judgment. I have used Vista plumbing for 20 years for toilet replacement to water heaters and I am always satisfied."

"Jared and his assistant Brandon were very personable and professional and we highly recommend them. They wore masks and offered to cover their shoes with 'booties' They diagnosed the problems and replaced 3 hose bibs and a garbage disposal.While fixing the older toilet they noted that the bolts connecting the tank to the bowl were leaking so they replaced the toilet. The batroom faucett handle was difficult to turn so Jared diagnosed the problem; the faucett needed new cartridges. He suggested the faucett might be under warranty so I called the company and new cartridges will be sent. All this was completed efficiently within one day. We can highly recommend Plumbing Plus"

"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!"
