Chimney Services in Norwalk, CT — Expert Guidance From Local Experience
Chimney Inspection
“How do I know if my chimney actually needs checking?”
People often question how to keep homes healthy, especially when everything appears fine. Many chimney problems are hidden—creosote buildup, blocked flues, or liner damage can develop quietly.
During inspections, we check the flue, liner, smoke chamber, crown, masonry joints, flashing, and damper operation. It’s a full assessment, not just a glance from the firebox.
A home in Rowayton had faint smoke odors. Our inspection revealed a partially collapsed liner and creosote buildup. Catching it early meant a simple repair, avoiding a larger hazard.
Regular inspections reveal hidden issues before they become serious.
Chimney Crack Repair
“Are tiny cracks really a problem yet?”
Small cracks often seem harmless, especially when the chimney still looks solid. But even hairline openings allow water, heat, and smoke to move into places they shouldn’t.
Over time, moisture expands those cracks during freeze-thaw cycles, weakening mortar joints and masonry. Left alone, minor cracking can lead to larger structural and ventilation problems.
Near East Norwalk, small mortar gaps were allowing water inside, causing interior staining. Repointing the joints and repairing the crown stopped the damage and restored proper draft.
Repairing small cracks early prevents larger, costlier problems.
Chimney Cleaning
“If I barely use my fireplace, do I still need cleaning?”
Yes. Even occasional fires produce creosote, and chimneys that sit unused often collect moisture, debris, and nesting materials. Restricted airflow can cause smoke odors and inefficient fires.
Cleaning removes buildup from the flue and restores proper ventilation while allowing early signs of damage to be spotted.
On Main Avenue, a long-overdue cleaning improved airflow, eliminated musty odors, and helped fires burn cleaner.
Routine cleaning keeps your chimney safe, efficient, and healthy.
Chimney Maintenance
“What does regular maintenance actually accomplish?”
Chimney maintenance focuses on prevention rather than repair. It helps identify early wear before it turns into leaks, draft issues, or structural damage.
In Norwalk, maintenance usually includes checking the chimney cap, crown, flashing, liner condition, and masonry joints. These areas are most exposed to moisture and weather-related stress.
Near City Hall, early flashing deterioration was corrected during routine maintenance, preventing water intrusion during the next heavy storm.
Consistent maintenance keeps chimney performance reliable year after year.
Level 2 Chimney Inspection
“When is a deeper inspection worth it?”
Level 2 inspections are recommended after storms, during home sales, or when appliances change. They use camera equipment to examine parts of the flue that can’t be seen during a visual inspection.
This deeper look helps identify hidden liner damage, obstructions, or moisture issues that could affect safety or documentation.
Near Cranbury Park, a Level 2 inspection before a home sale revealed a hidden bird nest, which was removed and documented.
Level 2 inspections provide clarity when conditions change.
Chimney Leak Repair
“How can I tell if my chimney is leaking?”
Chimney leaks often show up as stains, rust, or musty odors rather than visible dripping. Most originate from damaged crowns, deteriorated flashing, or missing caps.
On Burritt Street, sealing the chimney crown and repairing flashing stopped ongoing leaks after roof repairs failed.
Early leak repair prevents broader water and structural damage.
Chimney Cap Installation
“Is a chimney cap really necessary?”
Chimney caps protect against rain, debris, and animals while reducing downdrafts and moisture entry. Without one, chimneys are more vulnerable to blockage and weather damage.
A waterfront home on Rowayton Avenue solved repeated bird intrusions after installing a stainless-steel chimney cap.
A properly installed cap protects the chimney and improves airflow.

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. 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. We had Joe work on a gas fireplace in our new home. He was prompt, polite, and a pleasure to deal with. 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.
