“From the first phone call until the work was completed, I was very happy with the whole crew at Downey Plumbing. It was professional, efficient, reasonably priced and I like knowing I have a warrantied repair from a reputable company that's been in the community for a long time. I like knowing where to find someone later on if I need further help with this or another repair. Thanks DP!”
