Why Chimney Installation Matters
- Protects Against Fire Hazards: A properly installed chimney prevents sparks, excessive heat, and creosote buildup from endangering your home.
- Safely Vents Smoke & Gases: Correct liners direct smoke and carbon monoxide outdoors, keeping indoor air clean and safe.
- Prevents Water Damage & Structural Issues: Caps, crowns, and sealed masonry protect against leaks, moisture, and mold, saving on future repairs.
- Improves Heating Efficiency: Right-sized, well-lined chimneys improve draft, burn fuel efficiently, and provide hotter, cleaner fires.
- Extends Chimney & Fireplace Lifespan: Professional installation reduces wear, prevents costly rebuilds, and ensures a long-lasting, reliable system.
- Peace of Mind & Code Compliance: Installations meet NFPA and CSIA guidelines, keeping your home safe and fully compliant with Connecticut codes.

My Local New Haven Installation Experience
Last year, I worked on a home off Whitney Avenue where the homeowner kept dealing with constant smoke backing into the living room. The issue wasn’t the fireplace—it was the original liner installed decades ago, undersized and wrongly fitted. Once we replaced it with the correct stainless steel liner and cap, the difference was immediate. The draft improved, the smoke disappeared, and the fireplace finally worked the way it was meant to. Jobs like this remind me how much proper installation impacts everyday comfort in New Haven homes.

What Our New Haven Neighbour Are Saying About Our Services
EXCELLENT Based on 356 reviews Posted on Daniel JacobTrustindex verifies that the original source of the review is Google. GMT Chimney Services did an outstanding job installing a new liner in my chimney. Their price was nearly half of what other companies quoted, and the work was excellent. My chimney wasn’t drafting correctly, which caused my water heater to break. After the liner was installed, the issue was completely resolved. Highly recommend for their fantastic work!Posted on Gary SandersonTrustindex verifies that the original source of the review is Google. Outstanding service with Joe he was very helpful and I would recommend gmt and JoePosted on Kevin HealyTrustindex verifies that the original source of the review is Google. We had Joe work on a gas fireplace in our new home. He was prompt, polite, and a pleasure to deal with. I would absolutely use this company again and felt he went above and beyond to assist usPosted on josh aTrustindex verifies that the original source of the review is Google. 3.5 stars Not the worst not the best experience.. the guys that came and did inspection were great and knowledgeable, the guys that came and did the liner were also great.. Juan that came to check out my fireplace and put on the caps was excellent.. the guys that came and did the pointing, and outside work did ok work but didnt communicate with us... never rang doorbells or gave us calls, not good communication.... this comapny expect you to be home almost at all times says they will work with you in times so, scheduled a day to come work and needed someone to be home wife took day off and they tried to tell us no one was home didn't even knock or ring door bell... just left tried to tell us no one was home and that they rang door bell and knocked.. we have cameras and ring door bell and wife took day off.. one week goes by no calls nothing gave us 30 min notice called abut 9a.m to show up around 930... again the workers were all pretty good but the communication between them the lady in the office and home owners should be better.. she Called and asked for payment job wasn't complete.. caps were not install.. Juan came out again was great did what he had to do and bill was paid.. I'd love to use them again for a cleaning because the work was ok and some of the guys doing the work. But they need to realize that people work for a living and cant be home at all times and some of the workers and the office need to be able to communicate with the home owners and possibly each other a bit better.. the pricing was average better then some others and work was overall ok.. if your someone that can be home often this company will be perfect for youPosted on MariaTrustindex verifies that the original source of the review is Google.

Nice workPosted on Ravi GopieTrustindex verifies that the original source of the review is Google. Joe came to check my fireplace since I wanted to make sure I was good for the season before lighting it. He did a wonderful job of explaining that the fireplace was safe to use this year and advised me of when to contact them for a cleaning. He checked the firebox, and explained what was happening in the flue. I will certainly be calling GMT again for my future cleanings because of this interaction. Joe was friendly and warm, and did a great job explaining how to use the fireplace.Posted on אילן חרוביTrustindex verifies that the original source of the review is Google. Great service!
