Connecticut rain can ruin your chimney fast. Cracked chimney crowns and worn cement caps let moisture in, leading to leaks, stains, and structural damage inside your fireplace and roof. Protect your chimney with professional cap and crown repair.


If you’re searching for repair chimney cap near me or need urgent help with a chimney crown, leaking chase cover, or damaged flue, GMT Home Services is here for you.
GMT Home Services – Delivering trusted chimney repair, maintenance, and custom fabrication for Connecticut homeowners, making every job a priority.
Don’t let winter weather destroy your chimney. Heavy snow and ice crack chimney crowns, loosen caps, and cause water to seep into bricks and mortar. Early repairs save homeowners from expensive chimney rebuilding. Get expert chimney cap repair in CT before winter damage sets in.

A chimney cap acts as a protective cover on top of your chimney. It keeps rain, snow, and debris out, stops animals from nesting inside, and prevents sparks from escaping and causing chimney fires.
A cracked crown often shows visible lines or chips in the cement or concrete slab on top of your chimney. You may also notice water leaks, staining inside your fireplace, or damaged mortar around the bricks.
In many cases, a chimney cap can be repaired if the damage is minor—such as small cracks, rust spots, or loose fittings. Severe corrosion or missing parts usually requires replacement for a safe, long-lasting solution.
The average cost of chimney cap repair varies depending on the material and damage. Small repairs may cost just a few hundred dollars, while full replacements or custom fabricated covers cost more. A professional inspection gives the most accurate estimate.
DIY chimney repair is risky, especially when installing without professional guidance. Climbing on the roof without safety gear and tools can be dangerous, and using the wrong materials or sealants may lead to leaks or chimney damage. It’s always safer and more effective to hire certified chimney sweeps.
Experts, including the EPA, recommend an annual chimney inspection. Regular chimney maintenance helps catch cracks, damaged mortar, or loose caps before they lead to leaks or costly chimney repairs.
The chimney crown is the concrete or cement slab that seals the top of the chimney stack, preventing potential fire hazards . The chimney cap is a separate metal or custom fabricated cover installed above the crown to protect the flue from water, debris, and animals.
Leaving a chimney in poor condition can lead to moisture damage, cracked flue liners, chimney fires, and even structural repairs to the wood, brick, and masonry. Fixing small cracks early prevents major problems later.
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!
