Riordan and his guys are the best. I was impressed with their professionalism, expertise, and attention to detail. Riordan is a perfectionist, so you can be confident the job will be done correctly the first time. Highly recommend!!

It can be hard to find quality workmanship but Riordan and his team were fast, efficient, communicative, and pleasant to work with on a plumbing project at my home. I’d give more than five stars if I could and highly recommend Dugan mechanical! Thanks guys!
