We had an exceptional experience working with Robby the owner! We are experienced real estate professionals, and signed up with R Stud when a prior, trusted plumbing company came in wayyy too high on a bid for a parallel 2 unit gas water heater install, and a 4-bathroom complex renovation. Robby is extremely personable, knowledgeable, and fair. Communication is outstanding, and he goes out of his way to listen to owner needs, and accommodate any challenges or scheduling issues quickly and respectfully. The quality of their work is impeccable. We look forward to working with them on much larger projects in the future!
