I wasn’t anticipating a plumbing issue on a Friday before a long weekend but there I was with a busted hot water tank and a very wet floor. I called GEM at 1030am and by 130 Carmelo and Marcelo were at my house. They quickly diagnosed the situation and we scheduled an appointment for Sat am to have the tank replaced. Sat AM they were there earlier than planned and completed the job efficiently and professionally. Very happy with this company !

The tech Franny was awesome. So were the contact people on the phone. Franny cleared the drain lines from our cottage to septic. He also scoped it so we know what issues are needed to address in future. Only downside was the cost. They use a predetermined pricing for job type. Franny was here for 2 hours (though he drove 3 to get to us). The charge was over 1K per hour. Still, they showed up on time, booked it for day after the clog started, and now all is working well. I’d highly recommend them, especially Franny.
