GT Plumbing, Heating & Cooling works out of Norwalk and holds a 4.2-star Google rating from 18 ratings. Its own site pitches plumbing installation and repair, from leaking pipes and broken toilets to water supply lines and fixtures. A recent customer says they use GT every time they have a plumbing issue, and the problem is almost always fixed the same day or the next. A recent customer said GT unblocked a clogged sewer line and did the job well, but gave two stars over the follow-up. That customer was referred through an American Water Works repair plan and needed a receipt showing the work was paid; they said GT supplied only a paper showing what the work would cost, so AWW would not reimburse the $375, and repeated calls for a proper receipt went unanswered. A 2025 customer who moved to Norwalk from NYC said they hired GT for multiple jobs, called Tom the owner, and singled out Kat, the office manager, for handling city permits personally. A 2025 customer described Tom and his staff as reliable, prompt and clean. A 2024 customer said they hired GT to relocate their shower plumbing and fix a leaking toilet. A 2023 customer said GT responded and fixed their issues promptly at a reasonable rate, after an earlier plumber had never resolved the issue. A 2025 customer gave one star after a big job on their house, saying the crews kept changing, hydronic heating was installed in the wrong place twice, and register covers went in upside down. That 2025 customer also said other HVAC companies called the HVAC system GT designed and installed completely wrong, and that the duct cleaning company they hired called the duct work the worst installation it had ever seen.
“GT Plumbing is the best plumbing service in the entire area! They are incredibly fast, efficient, and reasonably priced. I use them every time I have a plumbing issue, and the problem is almost always fixed the same day or the very next day. You won’t be disappointed!”
The unblocked a clogged sewer line in my house. They did the job well, no issues there. They're getting two stars for their poor follow up service. I have a plumbing repair plan through American Water Works, that's how I was referred to this company. AWW was supposed to reimburse me for the work performed by GT Plumbing. In order to get reimbursed, GT Plumbing had to provide a proper receipt showing that I had paid for the work and they did not do that, they provided a paper showing how much it would cost to do the work but did not put that it was paid and as a result, AWW won't reimburse me the $375. I called GT Plumbing repeatedly to get a proper receipt but they do not pick up the phone. I believe this is because I left a message stating why I was calling and they don't care to help since it's not going to make them any money and they will have to spend a few minutes making a new receipt.
What a great company. I’ve had the pleasure of working with several of their techs. They are all very skilled and knowledgeable. I couldn’t imagine ever calling anyone else. I can’t recommend them more highly.
Couldn’t recommend GT plumbing in Norwalk enough! Tom and his staff do amazing work, super reliable, prompt and clean! Tom has great experience and runs a tight ship! Kat and the office staff are super responsive as well! Put their number on your fridge!
GT Plumbing is hands down one of the best companies we’ve worked with since moving to Norwalk, CT, from NYC. We’ve hired them for multiple jobs, and they’ve been consistently fantastic every single time. Before choosing GT Plumbing, I did my homework and spoke with several companies—but none came close to matching the professionalism, reliability, and quality of service these guys offer. A special shoutout to Kat, the office manager, who is truly the heart of the operation. She keeps everything running smoothly, answers all of our questions (or gets us to the right person who can), and even goes above and beyond—like handling city permits personally. Her organization and communication make every project feel stress-free. We’re extremely grateful for the excellent work and service from the entire GT Plumbing team, including Tom, the owner. Highly recommend them if you’re looking for dependable, top-notch plumbing services in the area! ⭐️⭐️⭐️⭐️⭐️ Regards, Mark Singh
