Bay Water Plumbing Reviews

“Super professional company! Alvaro showed up on time and totally exceeded expectations. Not only was he on time and polite, he also took the time to explain what changes he made and why. He took the time to answer all of our questions and didn’t leave until we were completely satisfied. I would recommend bay water to anyone! Ask for Alvaro!”

– Deserea T.

“After comparing different quotes and contractors, I asked Bay Water Plumbing to install a four-stage whole house filter system in my garage. Alvaro provided prompt service and set clear expectations on what the job would entail and the cost involved. On install day, he exceeded those expectations by minimizing interruption and designing a delivery system that is functional, attractive, and easy to use. In the end, they provided excellent service without incurring overages all in the time frame they provided.”

– Thomas N.

“Alvaro (Al) is a great guy. Professional and to the point. His workmanship is perfect. I was recommended to Al by SpringWell Water Softener company. I would highly recommend him for all plumbing work.”
