Chimney & Fireplace Services in Thompson, CT — Practical Care for Quiet, Rural Homes
Chimney Inspection
What could be happening inside my chimney that I’d never notice from the room?
In Thompson’s older and more rural homes, chimney problems rarely announce themselves early. Draft may seem fine, fires may burn normally, yet creosote buildup, liner separation, or internal wear can quietly restrict airflow or weaken venting paths.
A professional CSIA certified inspection evaluates the entire system—flue, liner, smoke chamber, crown, flashing, masonry joints, and damper—working together, not just what’s visible.
During an inspection near Thompson Hill, early liner deterioration was discovered after years of heavy winter use, allowing the issue to be corrected before airflow and safety were compromised.
Inspections reveal hidden conditions before they turn into functional or safety problems.
Chimney Repair
How does a chimney fail without obvious cracks or collapse?
In Thompson’s climate, deterioration often begins internally. Moisture enters through minor mortar gaps, freezes, expands, and weakens the structure from within—long before visible damage appears.
Chimney repair focuses on stabilizing masonry, restoring proper venting, and sealing pathways where water intrusion begins.
Near Quaddick Lake, repointing eroded joints and rebuilding a worn crown stopped moisture intrusion that had already begun affecting interior surfaces.
Timely repairs protect both the structure and the systems connected to it.
Chimney Cleaning
What actually builds up in a chimney over a full heating season?
Regular burning—especially wood—produces soot and creosote that cling to flue walls. In wooded areas like Thompson, chimneys are also vulnerable to leaves, debris, and nesting material that restrict airflow.
Cleaning removes these hazards, improves draft, and reduces fire risk during heavy winter use.
On Riverside Drive, a household that depended on their stove noticed better heat output and smoother draft immediately after a full cleaning.
Cleaning restores safe airflow and keeps winter heating reliable
Chimney Maintenance
Why do some chimneys age faster than others nearby?
Exposure makes the difference. Snow load, moisture retention, and freeze–thaw cycles gradually wear down caps, crowns, flashing, liners, and masonry—even when everything still appears functional.
Routine maintenance identifies early wear and corrects it before seasonal stress accelerates damage.
Near Fabyan Road, early flashing separation was corrected during maintenance, preventing leaks during spring snowmelt.
Maintenance slows wear and keeps chimney performance predictable.
Level 2 Chimney Inspection
When isn’t a standard inspection enough?
Sometimes, routine visual checks fall short—especially after major weather events, chimney fires, or when significant modifications have been made to heating appliances.
In these cases, a Level 2 inspection becomes essential, as it goes beyond surface evaluations by employing specialized camera equipment to reveal hidden internal issues, ensuring thorough assessment and peace of mind for both current homeowners and those preparing to sell.
Near Wilsonville Road, a Level 2 inspection identified an internal obstruction that was resolved and documented prior to closing.
Level 2 inspections provide certainty when conditions or ownership change.
Chimney Crack Repair
What happens if small chimney cracks are left alone through winter?
Unrepaired cracks act as gateways for moisture, especially during freeze–thaw cycles common in colder months. As water enters and freezes inside these crevices, it expands and worsens structural weaknesses, turning minor flaws into major deterioration by spring.
What might start as a hairline fracture can lead to spalling bricks, compromised mortar, and escalating repair costs, all of which could have been prevented with timely attention before the onset of harsh conditions.
At a home near Buckley Hill Road, early crack repair and crown sealing stopped moisture intrusion before it reached the chimney’s internal structure.
Early crack repair prevents exponential damage.
Chimney Leak Repair
Why does moisture show up even when the roof is fine?
Moisture can still infiltrate your chimney even if the roof appears intact because water often finds its way through less obvious entry points, such as cracked crowns, deteriorated flashing, porous brickwork, or a missing cap.
These vulnerabilities allow rain and melting snow to seep into the structure, sometimes travelling unseen behind walls or into the attic before any signs are noticeable inside the home.
Addressing these issues directly—rather than focusing solely on the roof—ensures a thorough solution, preventing persistent leaks and protecting both interior finishes and surrounding materials.
Near Route 193, crown sealing and flashing repair resolved persistent interior moisture that roofing work alone couldn’t address.
Accurate leak diagnosis protects surrounding materials and finishes.
Chimney Cap Installation
What’s the real risk of leaving a chimney uncapped?
Without a cap, your chimney becomes an open invitation to rain, snow, wildlife, and flying debris, each of which can disrupt airflow and damage interior components.
In places surrounded by woods, like Thompson, animals are especially prone to nesting inside, blocking the flue and threatening both safety and proper function.
A simple cap installation not only keeps these elements out but also preserves draft efficiency and reduces the likelihood of expensive repairs down the line.
Near East Thompson Village, repeated nesting issues stopped entirely after a stainless-steel chimney cap was installed, restoring proper draft and protecting the flue.
Chimney caps offer simple protection with long-term benefits.

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.

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.
