When your chimney’s smoke chamber is damaged, it can lead to poor airflow, creosote buildup, chimney fires, and costly repairs down the road. At GMT Home Services, our CSIA-certified technicians follow the highest safety standards recommended by the National Fire Protection Association (NFPA). With 12+ years of experience and more than 3,000 families served across Connecticut, we know how to restore your chimney system to peak performance.
Your smoke chamber connects the firebox to the chimney flue, guiding smoke and hazardous gases up and out through the chimney stack. When cracks, deterioration, or misalignment occur, it creates serious safety and performance issues.
Professional smoke chamber repair helps to:

“The Benefits of Chimney Smoke Chamber Parging!One of the most effective repair methods for a damaged chimney’s smoke chamber is parging. This process involves applying a smooth layer of specialized mortar or spray-on coating to seal cracks and gaps.”

It’s not always obvious when your chimney’s smoke chamber needs work. Look out for these warning signs:
If you notice any of these signs, schedule a professional chimney inspection right away. Early detection prevents extensive repairs and keeps your chimney safe.

The cost of chimney smoke chamber repair depends on several factors:
Our team provides clear, upfront pricing so you know the final cost before any repair work begins.
“Why is there water near my fireplace after it rains?”
A leaking chimney can silently damage your walls, ceiling, and roof. By the time stains appear, the problem is already deeper than you think. Don’t wait until repair costs triple

At GMT Home Services, we use advanced repair methods to restore your chimney’s structural integrity:
“How much is this chimney repair really going to cost me?”
Many homeowners hesitate because they fear sky-high repair bills. The truth? Small fixes now are far more affordable than waiting for major structural damage later.

“Will my chimney be safe enough to use this winter?”
Connecticut winters demand a reliable chimney. A small crack or creosote buildup can lead to smoke backup, fire hazards, or even carbon monoxide leaks. Peace of mind starts with a proper inspection.

Don’t wait until minor damage becomes a fire hazard. Whether you need smoke chamber parging, a chimney crown repair, or a full chimney replacement, GMT Home Services delivers expert results.GMT Home Services – Connecticut’s Trusted Chimney Specialists for Safe, Affordable Repairs
Chimney leaks are often caused by damaged flashing, cracked mortar joints, worn-out crowns, or moisture seeping through porous bricks. Regular inspections help identify issues early before water damage spreads.
Experts recommend at least once a year, especially before winter. Annual inspections catch hidden issues like creosote buildup, cracks, or animal nests that could pose safety risks.
Yes. A chimney leak can seep under shingles, rot the roof decking, and weaken structural framing. Addressing leaks promptly protects both your roof and your home’s interior.
Applying a breathable, professional-grade water repellent is the most effective method. Unlike paint or sealers, these allow moisture to escape while blocking water intrusion.
Signs include water stains near the fireplace, rust on the flashing, or visible gaps where the chimney meets the roof. An expert inspection confirms whether repair or replacement is needed.
It depends. Insurance usually covers sudden damage (like storm or fire damage) but not wear and tear from age or lack of maintenance. A professional assessment helps with claims.
Tuckpointing restores crumbling mortar joints, which prevents water infiltration and extends the chimney’s life. Without it, masonry can deteriorate and lead to costly rebuilds.
Costs vary based on the issue — minor mortar repairs may cost a few hundred dollars, while full rebuilds can run into the thousands. Getting a local inspection and estimate ensures accuracy.
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. 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!
