Chimney & Fireplace Services in Stamford, CT — Local Expertise
Chimney Inspection
“If my fireplace worked fine last winter, what could change?”
We hear this question often from Stamford homeowners. A chimney can perform well one season and quietly develop issues the next, especially after storms, moisture exposure, or heavy use.
What usually changes first isn’t performance — it’s condition. Creosote builds unevenly, liners begin separating at joints, or moisture starts working into crowns and masonry.
During inspections, we look closely at the flue, liner, smoke chamber, crown, flashing, masonry joints, and damper. Each area tells us how the chimney handled the last season.
In a home near Springdale, an inspection revealed early liner wear that hadn’t affected draft yet. Addressing it early prevented smoke issues before the next winter.
Conditions change quietly — inspections keep you ahead of them.
Chimney Repair
“Why fix parts of a chimney that aren’t broken yet?”
This is a fair question, especially when the chimney still looks solid. The reality is that chimneys often continue working even as internal components weaken.
Mortar joints break down, crowns absorb moisture, and liners develop hairline damage. Repairs focus on stabilizing these areas before they compromise venting or structure.
Near Glenbrook, repointing failing mortar and sealing the crown stopped moisture from spreading deeper into the chimney system.
Repairs done early protect the whole structure, not just the surface.
Chimney Cleaning
“How do I know when buildup has become a problem?”
Most homeowners don’t see buildup — they feel it. Fires start slower, smoke lingers, or faint odors appear even when the fireplace isn’t in use.
Even light burning leaves creosote behind, and unused chimneys collect moisture and debris that restrict airflow.
On High Ridge Road, a cleaning removed layered creosote that had narrowed the flue. Once cleared, draft returned to normal and odors disappeared.
Clean chimneys move air the way they’re designed to.
Chimney Maintenance
“What does chimney maintenance actually prevent over time?”
Maintenance slows wear before it becomes damage. In Stamford homes, that usually means checking caps, crowns, flashing, liners, and masonry joints — especially after seasonal storms.
Small adjustments help keep moisture out and components aligned.
Near North Stamford, early flashing wear was corrected during routine maintenance, preventing interior moisture issues during the next heavy rain.
Maintenance keeps chimney behavior predictable year after year.
Level 2 Chimney Inspection
“When should I consider a more detailed chimney inspection?”
A deeper inspection is usually recommended after major storms, during home sales, or when heating appliances change. Camera equipment lets us examine internal flue areas not visible during a standard check.
This helps identify hidden liner damage or obstructions that could affect safety or documentation.
In a Downtown Stamford condo conversion, a Level 2 inspection uncovered an internal offset that needed correction before closing.
When circumstances change, details matter.
Chimney Crack Repair
“Do hairline cracks actually get worse over time?”
Yes — especially with Stamford’s freeze-thaw cycles and moisture exposure. Small cracks allow water into masonry, where expansion slowly weakens surrounding materials.
In a home near Shippan Point, early crack repair and crown sealing prevented moisture damage from spreading into the chimney stack.
Small cracks are easier to manage before winter gets involved.
Chimney Leak Repair
“Why do chimney leaks show up even after roof repairs?”
Because chimney leaks usually start at different points. Crowns, flashing, and missing caps are common sources — especially in wind-driven rain near the coast.
On Cove Road, sealing the crown and correcting flashing resolved staining that roof repairs hadn’t addressed.
Finding the right source stops leaks from returning.
Chimney Cap Installation
“What changes once a chimney cap is installed?”
Caps reduce moisture entry, block animals and debris, and help stabilize airflow during windy conditions.
A home near Shippan Avenue dealt with repeated bird nesting issues. Installing a stainless-steel cap solved the problem and improved draft consistency.
A small addition at the top protects everything below it.

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.

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!
