Alex was quick to respond to my inquiry and was able to get my bathroom faucets installed same day. Super friendly, reasonable cost and great workmanship. He tested and made sure everything was running as it should. I would hire him again in the future.

A knowledgeable, clean, and professional plumber from CMS came to my house and diagnosed a leak that recently started coming through our drywall. This leak had baffled previous plumbing estimates that ranged heavily in price and would require opening entire walls. Our professional from CMS had a hunch it was not the plumbing, But a leak in our roof. He was 100% correct and he gave me the info on how to fix it. A good honest company with a problem solving mentality and wide range of skill.

GMS Plumbing is one of the best I’ve experienced. Alex was super quick to respond and provided good pricing. He showed up to my house on time and immediately knew what the problem was and fixed it. He also made sure to clean up any mess that was left behind. I will definitely be calling GMS Plumbing for any future needs.

Details: No, repair is not urgent • Only one drain has issues • Clogging • House
