A chimney flue is your home’s first line of defense against smoke, gases, and high temperatures. When cracked flue tiles, damaged mortar joints, or a leaking chimney are left unchecked, your family’s safety is at risk. At GMT Home Services, we specialize in chimney flue repair, chimney crown repair, and chimney flue relining to keep Connecticut homes safe, efficient, and structurally sound.
Every year, chimney fires caused by creosote buildup, cracked chimney flues, and damaged mortar result in costly repairs and even total home loss. According to the Chimney Safety Institute of America (CSIA), most chimneys need annual inspections to identify problems before they escalate.
Common dangers of neglecting flue repair include:
Regular maintenance by a professional chimney sweep prevents minor repairs from turning into costly, extensive projects.

Not all chimneys show damage on the outside. Inside your smoke chamber or behind the fireplace opening, you may find hidden issues such as:
If you suspect flue problems, don’t use your fireplace until your chimney inspected by certified professionals.

When clay flue tiles or mortar joints fail, relining is often the safest, most cost-effective option. Our team offers flue liner replacement with durable larger stainless steel liners that outperform clay tiles and resist corrosion.
Benefits of relining include:
With relining, small cracks won’t become severe structural damage, and relining reduces total cost compared to repeated patchwork repairs.

“Cold drafts and smoke problems aren’t just frustrating—they’re signs of chimney damage. Homeowners across Connecticut trust GMT Home Services for chimney inspections, cap replacements, and flue repairs that keep homes warm, safe, and efficient.”

A cracked chimney flue allows heat, smoke, and carbon monoxide to escape into your home. Over time, this can cause chimney fires, structural damage, and costly repairs. Even small cracks in clay flue tiles should be addressed quickly to keep your chimney safe and compliant.
The chimney flue repair cost depends on the type of damage and chimney type. Minor repairs like sealing mortar joints may cost $250–$1,000, while chimney flue relining with a stainless steel liner can range from $2,000–$7,000. A professional inspection will give you a clear estimate.
No. Using a fireplace with a cracked chimney flue is unsafe. Heat and gases can escape through the damage, increasing the risk of chimney fires and carbon monoxide poisoning. Always have your chimney inspected before use.
Most chimneys should have annual inspections by a certified chimney sweep. Regular inspections help identify small cracks, damaged mortar joints, moisture damage, and creosote buildup before they turn into fire hazards or require extensive repairs.
Flue tiles often crack due to thermal stress, poor installation, moisture damage, or corrosive byproducts from wood burning. Over time, these stresses create large cracks that compromise chimney safety. Relining with a larger stainless steel liner is a long-term fix.
Yes. While minor repairs may work temporarily, chimney flue relining provides lasting protection. Installing a stainless steel liner or cast-in-place liner keeps your chimney structurally sound, reduces fire risks, and often lowers long-term repair costs.
A chimney crown is the concrete or masonry top that seals the chimney stack, while a chimney cap is a protective cover (often metal) that prevents water, debris, and animals from entering the flue. Both are essential to prevent water leaks, damaged mortar, and costly chimney repairs.
Homeowners insurance may cover chimney repair costs if damage is caused by a sudden event, like a chimney fire or storm. However, gradual wear, cracked flue tiles, or lack of regular maintenance are usually not covered. That’s why proper repairs and inspections are key to avoiding uncovered expenses.
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!
