The words out about Downey Plumbing!

“Downey Plumbing is our go-to for all our plumbing needs. We discovered them after another plumber left us stranded. We now use them exclusively and you will too! It is easy to get an appointment, their technicians are professional, friendly and explain the issues in an understandable way. Their prices are great and they don’t upsell or pressure you into anything. Do yourself a favor and call Downey first!!” - Michelle Deziel
“Our water heater went out on the weekend. Downey plumbing was so responsive and the bid came in very reasonable. The tech came out same day and replaced our water heater with very little down time. The job was exactly as quoted. I really appreciated the professionalism of the tech. Thank you Downey plumbing for getting us back up and running, because cold showers are no fun!” - Christine Rankin
