Bay Water Plumbing Reviews

“I requested a quote online and Bay Water called right away. Set schedule and the company owner showed up as scheduled. Perfect! Upon arrival and going over the project I was able to immediately get a quote for the work to be completed. Very honest and reliable! I already passed Bay Plumbing information to my friends and neighbors and will certainly use them again in the future. Thanks Bay Water Plumbing!”

“I woke up to no hot water this morning and Bay Water Plumbing was recommended to me so I called and spoke with Al. He was so kind and was able to schedule a tech within 2 hours. When I inquired on the service cost and having very little money after losing my job, Al took the time to help me over the phone to try and resolve the issue. My pilot light had gone out and Al patiently waited after it was relit to make sure there were no other issues. THANK YOU, AL!! I'm praying this water heater will hold out until I get a new job and will for sure call Al @ Bay Water
Plumbing to replace.”

“Bay Water did an excellent job in fixing the kitchen sink and replacing both faucet and garbage disposal. Alvaro was very professional. He showed up and started working right away! He went to the store and got the parts. He finished on time and left everything clean. The price was very reasonable. I will be recommending Bay Water to my friends and family.”
