Donovan Plumbing Customer Testimonials

⭐⭐⭐⭐⭐

"This is the first job I gave to John. I am a contractor in Salem and hired him to do my 2 house project. He did a great job and I will definitely use him again!"

⭐⭐⭐⭐⭐

"Donovan Plumbing installed all of the plumbing when we built our new home - 
kitchen, bath, etc. What a fantastic result! People who have seen my cellar have asked who did such a wonderful, neat, well placed job. This company is THE BEST in the area!"

⭐⭐⭐⭐⭐

"Our water heater starting giving trouble. A small leak, then a week or so later it became major. I was trying to find a water heater and have it replaced in a hurry. Luckily, I finally found John. He realized our desperate situation and wanted to help.

He rearranged some things and made this job a priority. He listened to what I wanted for a heater but after thinking about all options I decided on a different system. He gave me the best advice. He was a plumber that I could have complete confidence in and who was very trustworthy!"
