Chimney & Fireplace Services in Derby, CT — Stay Warm and Safe
Chimney inspection
What happens if I skip my yearly chimney inspection in Derby?
We hear this question from Derby homeowners all the time, especially when the fireplace seems to work just fine. The truth is, river moisture and sharp winter cold take a quiet toll on chimneys over time. Even small cracks, draft issues, or hidden leaks can grow into problems if not caught early.
During a recent inspection near Hawkins Street, everything looked normal from the ground. A camera scan revealed a slight flue shift from repeated freeze-thaw cycles. Catching it early prevented a major repair right before the heating season.
Regular inspections keep your chimney safe, efficient, and ready for winter.
Chimney repair
Why do chimney repairs become urgent so quickly in Derby?
Derby’s riverside location means more humidity than most expect, which accelerates wear in masonry and mortar joints. Small cracks or gaps left unchecked let water in, and the freeze-thaw cycle spreads damage fast.
I recently fixed a tiny mortar gap in Derby Neck that was causing a second-floor wall to stain. A simple repointing and crown touch-up stopped the leak and stabilized the chimney for the season.
Addressing repairs early keeps Derby chimneys solid and saves money down the line.
Chimney cleaning
Does chimney cleaning really make a difference in how your fireplace heats?
In Derby — absolutely. Cold, damp air creates thicker creosote buildup, and once it coats the flue walls, your chimney draft weakens. Cleaning removes the buildup so your fires burn warmer, cleaner, and without smoke drifting back into the room.
Last winter, I cleaned a chimney off Milford Road where the flue was so constricted the homeowners thought their insert was failing. A single sweeping brought the draft back instantly — they said the living room felt warmer that same night.
A clean chimney keeps every fire safer, stronger, and more enjoyable during Derby winters.
Chimney maintenance
Is chimney maintenance really necessary if nothing looks wrong?
It’s like changing the oil in your car — you don’t wait for a warning light. Chimney maintenance keeps moisture out, prevents softening mortar, and stops the slow wear that Derby’s climate brings. It keeps everything working smoothly, even when winter hits hard.
During a routine visit in Hilltop, I caught small crown wear that had just started absorbing moisture. A quick seal and tune-up stopped the damage before it could spread. Sometimes the smallest preventive step makes the biggest difference.
Seasonal maintenance keeps Derby chimneys strong through every cold snap.
Level 2 chimney inspection
When do Derby homeowners actually need a Level 2 chimney inspection?
Whenever something changes — a home sale, a storm, a remodel, or a new stove or insert — a Level 2 inspection gives a complete look inside your chimney. It uses video scanning to catch problems long before they become visible.
One storm-season call in East Derby showed a flue tile that had shifted after a winter windstorm. The homeowner only noticed a faint smoky smell. The Level 2 scan told the story immediately — and it was a fast fix because we caught it early.
A Level 2 inspection brings clarity anytime your chimney situation changes.
Chimney leak repair
Why is my chimney leaking even when the bricks look perfect?
Because most leaks don’t start in the bricks. They begin at the crown, flashing, cap, or tiny mortar gaps. Derby’s wet seasons and river humidity make those vulnerable points wear faster, and leaks often stay hidden until they show up inside the home.
A homeowner in the Olivia Street area called about a faint ceiling stain. The issue? A flashing opening no wider than a fingertip letting in meltwater every storm. A simple floating flashing repair and waterproofing stopped it instantly.
Most chimney leaks are hidden — but easy to fix once you find the source.
Chimney cap installation
Do I really need a chimney cap in Derby?
If you’re anywhere near the river or wooded neighborhoods, absolutely. A chimney cap keeps rain, snow, and wildlife out of the flue and protects your chimney from moisture — the biggest threat to long-term chimney health in Derby.
I installed a cap for a family near Derby Greenway who kept hearing birds inside their chimney each spring. Once the cap went on, the noise stopped, the airflow improved, and their flue stayed dry through the next storm season.
A cap is the simplest way to protect your chimney from Derby’s weather and wildlife.

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.

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.
