Most homeowners don’t think about their chimney until something goes wrong. Here’s how to spot trouble before it turns into expensive damage:
Cold Drafts Indoors – Feeling a chill around your fireplace? Your damper may not be sealing properly.
Moisture or Leaks – Water stains, damp bricks, or puddles inside the firebox often mean your cap isn’t blocking rain and snow.
Animal Guests – Hearing scratching or finding nesting materials? Birds, squirrels, or raccoons likely entered through a damaged or missing cap.
Rust or Corrosion – Orange streaks or metal flaking are early warnings that moisture is eating away at your damper or cap.
Smoke Problems – Struggling to start a fire or noticing smoke backing up? Poor draft control may point to a failing damper.
Visible Damage – Bent screens, cracked masonry, or missing pieces are clear signals your chimney needs immediate attention.

Popular options include single-flue caps, multi-flue caps, and specialty caps such as top-sealing damper caps or vacuum caps. Materials often include stainless steel, copper, or galvanized steel, all selected based on durability, aesthetic, and performance needs.
Installation is best handled by professionals like roofing contractors, masonry experts, or certified chimney sweeps. They have the tools, safety knowledge, and experience needed to work at heights and integrate properly with the chimney system.
While DIY installation is possible, it’s not recommended due to the risks of working on a roof. Professional installation is safer and more reliable.
Yes. The right cap can help reduce downdrafts and improve fireplace performance—while the wrong one may worsen draft problems. Choosing the appropriate design and material is essential.
A chimney damper allows controlled airflow in your chimney flue—and when closed, it prevents warm air from escaping and cold air from entering your home, boosting energy efficiency and comfort.
By sealing the flue when not in use, a damper helps avoid unnecessary heat loss, particularly during the winter months, leading to lower heating bills.
Signs like strange sounds (squeaking or scraping), water or debris in the firebox, animal intrusions, difficulty starting fires, smoke backup, or drafts suggest your damper may need inspection or repair
Proper installation ensures correct draft, protects from corrosion and weather, aligns with building codes, and matches the flue size. Proper placement—whether a throat damper or a top damper—is also essential.
The NFPA recommends inspecting your chimney, fireplace, and vents at least once per year for structural soundness and cleanliness.
Routine maintenance improves your chimney’s performance and lifespan, helps catch issues early, and prevents safety hazards such as creosote buildup, flue erosion, and structural damage.
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!
