Complete Chimney & Fireplace Services in Durham, CT — Inspection, Cleaning & Repair
Chimney Inspection
“If everything seems fine, do I still need a chimney inspection?”
In Durham, yes — absolutely. Chimneys often appear normal while developing issues deep inside the flue. Inspections focus on what homeowners can’t see: liner condition, creosote buildup, airflow performance, moisture intrusion, and early structural wear caused by seasonal temperature swings.
With many Durham homes relying on wood-burning fireplaces or stoves, annual inspections help catch problems early—before they become safety risks.
During an inspection near Main Street, a fireplace that “worked fine” revealed cracked liner sections and early moisture damage inside the flue. None of it was visible from the living room, but left unchecked, it would have worsened quickly.
Understanding what’s happening inside your chimney is the safest form of prevention.
Chimney Repair
“When does small damage become a real safety issue?”
Often sooner than homeowners expect. Hairline cracks, deteriorating mortar, loose bricks, or failing caps allow moisture and heat to weaken the chimney from the inside out. Over time, those small openings compromise structure, draft, and safety.
Durham’s older chimneys are especially vulnerable after years of seasonal stress.
On a historic Durham property, what looked like a minor exterior crack turned out to be widespread internal deterioration once inspected. Addressing it early prevented serious structural failure.
Timely repairs protect safety, structure, and long-term home value.
Chimney Cleaning
“How quickly does creosote build up during a Durham winter?”
Faster than most homeowners realize. Cold flue temperatures combined with regular fireplace use allow creosote to accumulate quietly. Even chimneys without smoke issues can develop dangerous buildup.
Professional chimney cleaning removes soot, creosote, and debris while restoring proper airflow.
In a Durham colonial, heavy creosote buildup was discovered despite moderate fireplace use. Cleaning eliminated a serious fire hazard and immediately improved draft.
Clean chimneys burn safer, perform better, and are easier to maintain.
Chimney Maintenance
“What does chimney maintenance actually prevent?”
Maintenance is about slowing wear before it turns into damage. It addresses small cracks, worn flashing, loose caps, and early moisture entry that can quietly worsen between inspections.
Durham’s humid summers and icy winters accelerate deterioration when vulnerabilities go unchecked.
Routine maintenance helps extend chimney lifespan, stabilize performance, and reduce the need for major repairs.
Small attention now prevents big problems later.
Level 2 Chimney Inspection
“When is a Level 2 inspection actually necessary?”
Level 2 inspections provide a deeper look using internal camera scanning. They’re recommended after chimney fires, major storms, appliance changes, or during real estate transactions—especially common with Durham’s older homes.
Many historic chimneys weren’t built to modern safety standards, making deeper evaluation essential when conditions change.
When surface checks aren’t enough, a Level 2 inspection provides clarity and confidence.
Chimney Crack Repair
“Are hairline cracks really a big deal?”
Yes. Hairline cracks are often the first entry point for moisture. In Durham’s climate, that moisture expands during freeze–thaw cycles, accelerating deterioration from the inside out.
Early crack repair stabilizes masonry, protects the liner, and prevents damage from spreading.
In this climate, cracks rarely stay small for long.
Chimney Leak Repair
“Why is my chimney leaking if the roof is fine?”
Chimney leaks often originate where roofing protection ends—at flashing, crowns, caps, or porous masonry joints. Water doesn’t need much space to travel once it finds a pathway.
Durham’s damp conditions allow even minor failures to cause hidden moisture damage.
Leak repair focuses on sealing vulnerable areas and redirecting water away from the chimney system before interior damage develops.
Stopping leaks early prevents costly surprises later.
Chimney Cap Installation
“Do I really need a chimney cap?”
Yes. Chimney caps are one of the simplest ways to protect the entire system. They block rain, snow, animals, leaves, and debris while improving draft consistency.
In a town like Durham—surrounded by trees and exposed to unpredictable weather—an uncapped chimney is far more vulnerable to moisture damage and blockages.
A properly installed cap protects everything below it.

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.

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!
