Groton, CT Chimney & Fireplace Services Focused on Safety and Compliance
Chimney Inspection
“How do I know my chimney is actually safe to use?”
Most homeowners in Groton light the first fire of the season assuming everything’s fine. The truth is, you can’t see what’s happening inside the flue from the living room. That’s where inspections matter—not to scare you, but to give you real certainty before you start using your fireplace regularly.
A homeowner off Poquonock Road told me he hadn’t had his chimney checked in a couple of years and figured it was “probably fine.” During the inspection, we found a loose flue tile and early creosote glazing—nothing urgent yet, but things that would’ve gotten worse quietly. He handled it early and went into winter knowing his system was safe.
A simple inspection now helps prevent surprises later in the season.
Chimney Repair
“Do small chimney problems really turn into big ones?”
They can—but not overnight. Most chimney repairs in Groton start small: worn mortar, minor gaps, early moisture damage. When those issues are caught early, repairs are usually straightforward and contained.
Recently in the Eastern Point area, a homeowner noticed a slight draft and called just to be safe. We found a failing mortar joint and a small moisture entry point. Left alone, it could’ve led to serious damage. Addressed early, it was repaired in a single visit.
Early repairs keep your chimney stable and save you from larger work down the road.
Chimney Cleaning
“Is soot actually dangerous, or just dirty?”
Soot doesn’t always stay loose and dusty. In Groton, especially near the Thames River, moisture can cause soot to harden into creosote faster than homeowners expect. That buildup isn’t just messy—it’s flammable.
A family near Groton Long Point reached out after noticing a burnt smell whenever the fireplace warmed up. During the cleaning, we found thick, glazed creosote higher in the flue—the kind that doesn’t brush off easily and can ignite. Once it was properly removed, the smell disappeared immediately.
A clean chimney burns cleaner, drafts better, and reduces fire risk.
Chimney Maintenance
“Is annual maintenance really necessary?”
Chimney maintenance works the same way routine car maintenance does. You don’t wait for a breakdown—you keep things running smoothly. In coastal towns like Groton, salt air and humidity are especially hard on brick, mortar, and metal components.
In the Mystic section of Groton, a homeowner told me she used to wait until something looked wrong. After scheduling routine maintenance, she realized how much smoother her system operated—and how little it cost to stay ahead of issues.
Consistent upkeep prevents unexpected repairs and extends the life of your chimney.
Level 2 Chimney Inspection
“Why would I need a deeper inspection if nothing looks wrong?”
Level 2 inspections aren’t about worst-case scenarios—they’re about clarity. If you’ve bought or sold a home, changed heating appliances, or noticed drafting issues, a standard inspection may not be enough. Camera inspections reveal conditions you simply can’t see from the outside.
Near Gungywamp, a homeowner with a 1950s fireplace requested a Level 2 inspection after moving in. Everything appeared fine at first glance, but the camera showed interior cracking hidden behind the masonry. Because it was caught early, repairs were controlled and predictable.
A Level 2 inspection removes guesswork and gives you real answers.
Chimney Crack Repair
“If it’s just a hairline crack, does it really matter?”
It does—because moisture doesn’t need much space to get in. Along the Groton shoreline, freeze-thaw cycles can turn small cracks into larger structural problems faster than most homeowners expect.
A homeowner near Fort Griswold noticed a thin crack along the brick face and almost ignored it. Upon inspection, water had already started working its way behind the surface. Sealing it early prevented expansion and avoided far more costly repairs later.
Addressing cracks early helps your chimney stand up to seasonal weather.
Chimney Leak Repair
“Where do chimney leaks usually come from?”
Most chimney leaks in Groton aren’t obvious. They usually come from failing flashing, small gaps, or worn seals—places where wind-driven coastal rain can slowly work its way in.
In Noank, a family noticed faint staining near their fireplace. The roof was fine. The issue turned out to be a hidden flashing gap beneath the brick skirt. Once sealed properly, the staining stopped and the damp smell disappeared.
Stopping leaks early protects your chimney from long-term moisture damage.
Chimney Cap Installation
“Does a chimney cap really make a difference?”
It does. A chimney cap keeps out rain, animals, leaves, and debris—protecting the flue, liner, and smoke chamber from damage.
In the Groton Bank area, a homeowner kept hearing noise inside the flue. The chimney was missing a cap, and squirrels had moved in. A stainless-steel cap solved the issue immediately and prevented future entry.
A properly fitted cap is a small upgrade with long-term benefits.

Honest Feedback from Our Clients
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.

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.
