Tom G was extremely knowledgeable, professional and patient in dealing with us. The fact that he has 25 years experience in the plumbing trade was comforting when making a decision on a new water heater. During installation he found a faulty presure valve and was able to install immediately. Knowing that someone of his caliber was taking care of these two issues put me at ease since my basement is fully finished and either one of these could have cost us thousands in repair and restoration. He wore the booties and put down floor covering and was extremely neat and clean and came equipped with all materials and tools to complete the job efficiently. As my wife would say,"we now have a plumbing guy".

Our plumber, Caleb, showed up 12 hours after we first requested a plumber, he was very competent, extremely polite, fixed our leaking pipe, Installer dishwasher help me swap out the old one, and install brand new guts on one of our toilets. The guy was fast. It was all done in a matter of two hours! The price was reasonable thank you Caleb and thank you, Donnelly’s. Don’t lose Caleb the man is a credit to your team. Come review time, keep him happy: You don’t want to lose Caleb to a competitor! The man is worth his weight in gold! If we ever need another plumbing service, we want Caleb, so don’t let him get off your staff as we may need him again sometime!
