From start to finish, their service is top-notch. The team is incredibly professional and communicated every step of the way. They are prompt, efficient, and went above and beyond to make sure the job was done right. It's rare to find such excellent service paired with outstanding communication.

Fantastic service and excellent communication. Could not be happier with the service and installation. Rob and team are fantastic to work with. Just adding to this review as we’ve had the team out for several projects and could not be happier with responsiveness, service, and quality of work.

Tricia St.Laurent
Very timely and courteous scheduling. And the 2 techs arrived at the time promised, and were respectful of my home. Gave a fair and accurate estimate or plumbing repairs to be done. Then did the job professionally at quoted price. Very happy with their service and would definitely call Rob Roy again!
