Chimney and Fireplace Services in Shelton, CT — Ensuring Safety
Chimney Inspection
“How would I know if something is wrong inside my chimney?”
This is one of the most common questions we hear in Shelton. From the living room, everything can seem normal—fires burn, smoke rises, and the chimney looks fine from the outside. The issue is that most chimney problems develop where homeowners can’t see them.
Early creosote buildup, liner wear, small blockages, or moisture intrusion don’t always affect performance right away. But over time, they change how safely and efficiently a chimney vents.
During inspections, we look closely at the flue, liner, smoke chamber, crown, flashing, masonry joints, and damper operation. Each area tells part of the story.
In a home near Huntington Center, an inspection revealed early liner separation that hadn’t yet caused smoke issues. Catching it early meant a targeted repair instead of a larger correction later.
Inspections bring clarity before problems make themselves known.
Chimney Repair
“If my chimney hasn’t failed, why fix anything yet?”
Shelton homeowners ask this often, especially when the chimney still looks solid. Chimneys are resilient—they keep working even as internal components slowly wear down.
Mortar joints erode, crowns absorb moisture, and liners weaken over time. Repairs focus on restoring stability and safe venting, not just addressing surface damage.
Near White Hills, deteriorating mortar joints were allowing moisture into the structure. Repointing and crown reinforcement stabilized the chimney before freeze-thaw cycles caused deeper damage.
Repairs done early protect the chimney before failure forces bigger work.
Chimney Cleaning
“Can buildup really be an issue if I don’t burn often?”
Yes—and this surprises many Shelton homeowners. Even occasional fires leave creosote behind, and chimneys that sit unused often collect debris, moisture, or nesting material.
Restricted airflow doesn’t always show up immediately. It often starts as lingering odors or sluggish draft.
On Bridgeport Avenue, a long-overdue cleaning removed layered buildup that had been narrowing the flue. Once cleared, airflow improved and smoke odors disappeared.
Cleaning keeps airflow reliable, even with light fireplace use.
Chimney Maintenance
“What’s the difference between maintenance and repair?”
Maintenance is about slowing wear—not fixing damage after it happens. In Shelton homes, it usually means checking the areas most exposed to weather: caps, crowns, flashing, liners, and masonry joints.
These small adjustments help prevent moisture entry and shifting components.
Near Indian Well State Park, early flashing wear was corrected during routine maintenance, preventing water intrusion during the next heavy rain cycle.
Maintenance keeps small changes from turning into repairs.
Level 2 Chimney Inspection
“When is a standard inspection not enough?”
A deeper inspection is usually recommended after storms, during home sales, or when heating systems change. Camera equipment allows us to examine internal flue areas that can’t be seen otherwise.
This helps identify hidden liner damage, obstructions, or moisture issues that affect safety or documentation.
Near Shelton Lakes, a Level 2 inspection before a home sale revealed a concealed blockage that was cleared and documented without delaying the transaction.
When circumstances change, a closer look brings certainty.
Chimney Crack Repair
“Can small chimney cracks wait another season?”
Small cracks rarely stay small. Once water enters masonry, freeze-thaw cycles widen those openings and weaken surrounding materials.
In a Downtown Shelton home, early crack repair and crown sealing stopped moisture from spreading into adjacent joints.
Addressing cracks early keeps damage contained.
Chimney Leak Repair
“How can I tell if the chimney—not the roof—is causing leaks?”
Chimney leaks don’t always drip. They often show up as staining, rusted components, or musty smells that linger.
Most leaks trace back to crowns, flashing, or missing caps—areas that handle direct exposure.
On River Road, sealing the crown and correcting flashing resolved interior staining that roof work alone hadn’t fixed.
Finding the true source of moisture prevents repeat damage.
Chimney Cap Installation
“What problems does a chimney cap actually prevent?”
Caps do more than block rain. They keep animals out, reduce downdrafts, and limit moisture entering the flue.
A home near the Housatonic River had repeated bird nesting issues. Installing a stainless-steel cap solved the problem and improved airflow consistency.
A small addition at the top protects the entire chimney system.

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.

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!
