Greg Maier

We had tried several larger plumbing companies in the past and were consistently disappointed. Finding Jason and Dowd Plumbing was a major improvement. Their team has reliably handled all of our building and business plumbing needs, and their pricing is always clear and transparent. Every job has been completed with excellent quality — we haven’t experienced a single issue or failure. I confidently recommend Dowd Plumbing to any business looking for dependable, professional plumbing services. They’ve proven to be a trustworthy and reliable choice.

On 1/26/26 I had DOWD PLUMBING INC recommended to me by my brother-in-law. Enrique and Josh came out and immediately located my water leak. I didn’t want my house foundation dug up without having professionals pinpoint an approximate area. They were very professional and knowledgeable! I would highly recommend this company for all your plumbing needs????

I called AO Dowd plumbing because of a possible leak coming from an upstairs bathroom. Josh arrived on time and conducted a thorough check but found no evidence of a leak. A restoration company came the same day and concurred with his findings . Josh was thorough, friendly and explained everything to me. I will call AO Dowd if I need their service in the future. Great service guys!
