Customer Reviews
McGill Plumbing and Water Treatment is a business with 3 generations of satisfied customers. Cody and Johnny were professional, knowledgeable and friendly. Highly recommend for any plumbing issues you may have.
I've been using McGill for nearly 20 years. It started with a stupid mistake that broke an outdoor faucet on a weekend and McGill was out quickly to fix the problem. Over the years they have replaced toilets and fixed other plumbing leaks, and are responsive. There's a reason they have been around so long! And Tonya is always great to work with, as well as the other employees I have encountered.
I am extremely happy with McGill Plumbing. They moved my plumbing from the floor to the attic. Jake and Bobby were professional, friendly, explained what they were doing, and very easy to work with. Kudos to McGill Plumbing. Reasonable price. Everything was upfront. No surprises. I would highly recommend.
Just an incredibly professional job installing my hot water heater by Mark. Old piping was a mess and he cleaned it all up with sweated(soldered) copper pipes! Same price or cheaper than the competition and they don’t solder copper. Can’t be happier.
I called McGill plumbing to fix a plumbing issue I was having. They scheduled someone to come to my house within 30 minutes. Chris from McGill addressed the problem and fixed it for me. He was very professional and kind.. I will continue to use McGill if I have anymore problems in the future.
