We had a leak in the feed tube going into our toilet. It leaked down through the ceiling into our kitchen. I called GEM and they sent technicians right out to fix the problem. The technicians arrived, assessed the problem and gave us a very reasonable quote. The technician also noticed veteran plates on my car and applied a 10% discount! They fixed the problem, noticed that the feed tubes to my sink didn't look good and corrected them as well. Both technicians were very personable and kind. They helped lower our anxiety as well. Great experience! Highly recommend GEM plumbing!

Two great gentlemen (Brandon and Maxwell) came to my house to fix a leaking faucet. They explain all the questions from me and wife. They even give nice advice about reglazing the sink. Due to the distance between the cabinet and the sink, they tried very hard to find the best possible solution for us and install a new faucet. It is a wonderful job!! Highly recommended!!

I have already posted a 5 star review and want to post another. Four years after becoming a GEM customer, I remain totally satisfied with their service. I could name a lot of names: Nathan Campbell, Tony Rossi, Michael Hassel, Steven Gray and his partner Chase, and others who have all been incredibly responsive and totally dedicated to solving the problem at hand. I think for an organization as large as GEM they have managed to recruit and train a great group of professionals. All that matters to me is quick access to such a good group caring pros.

The service and attention to detail is excellent. They identified the problems with 2 toilets and 2 shower faucets and resolved every issue with the least amount of disruption. They even went the extra mile to identify the cause of a ceiling stain to make sure it wasn't from water. I recommend them highly for quality of work, knowledge and efficiency.
