Chimney & Fireplace Services in Greenwich, CT — Coastal Protection for Timeless Homes
Chimney Inspection
“Do I Really Need a Chimney Inspection If Everything Looks Fine?”
We hear this question often from Greenwich homeowners, especially when the fireplace hasn’t caused obvious trouble. The challenge is that most chimney problems start out of sight. Damage tends to develop inside the flue, behind the crown, or where flashing meets the roof—areas homeowners can’t safely evaluate themselves.
Chimney inspections focus on what isn’t visible from the ground. Creosote buildup, liner cracks, early moisture intrusion, drafting issues, and masonry deterioration all tend to progress quietly, especially in coastal conditions where salt and humidity accelerate wear.
Chimney Repair
“When Does a Chimney Actually Need Repair?”
Chimney repair becomes necessary when inspections reveal compromised structure, deteriorated liners, loose masonry, or unsafe venting. In Greenwich, repairs are often the result of gradual coastal exposure rather than sudden events.
Typical repairs include masonry restoration, liner repair or replacement, crown rebuilding, flashing correction, and stabilizing sections affected by moisture or wind.
One Cos Cob homeowner noticed only minor exterior cracking. Inspection showed moisture had already reached the liner. Addressing it early prevented a much larger rebuild before winter.
Repairs are most effective when they’re timely—not delayed.
Chimney Cleaning
“Why Does My Fireplace Smoke or Smell, Even When I Don’t Use It Often?”
In many Greenwich homes, this comes down to airflow restriction and buildup.
Chimney cleaning removes creosote, soot, debris, and nesting material that interfere with proper draft. Along the coast, moisture can harden creosote faster and trap odors inside the flue, even in fireplaces that see light use.
In homes closer to the Sound, we often find that humidity-driven residue compromises airflow long before homeowners expect it to.
Cleaning restores safe airflow and helps prevent fire and air-quality issues.
Chimney Maintenance
“Is Chimney Maintenance Really Necessary If Nothing Is Broken?”
Maintenance is what keeps “nothing is broken” from becoming an expensive surprise.
In Greenwich, maintenance focuses on the areas most affected by coastal exposure—chimney crowns, caps, flashing, mortar joints, and masonry surfaces. Salt air and moisture slowly weaken these components, allowing water entry long before visible damage appears.
Addressing small vulnerabilities early helps slow deterioration and extend the life of the entire chimney system.
Maintenance is preventive—it’s how chimneys hold up long term in coastal conditions.
Level 2 Chimney Inspection
When a routine chimney check isn’t enough, how can you be sure what’s really happening inside the flue?
When a home is being sold, renovated, has experienced a chimney fire, or shows unexplained smoke or odor issues, a Level 2 inspection provides clarity. Video scanning inside the flue reveals gaps, corrosion, blockages, and liner separation that standard visual checks can’t confirm.
Inspections aren’t about assuming something is wrong—they’re about understanding what’s happening before damage spreads.
Chimney Crack Repair
“Are Small Chimney Cracks and Leaks Actually a Big Deal?”
Near the coast, they usually are.
Hairline cracks in masonry, crowns, or mortar joints allow moisture inside. Once water enters, freeze–thaw cycles expand the damage, leading to spalling brick, interior leaks, rusted components, and liner failure. Many Greenwich homeowners don’t notice the issue until stains or odors appear inside the home—well after the damage began.
Crack repair and leak repair focus on stopping moisture at the source by restoring crowns, sealing masonry, correcting flashing failures, and addressing cap issues.
Stopping water early protects both the chimney and the home around it.
Chimney Cap Installation
“Does a Chimney Cap Really Make That Much Difference?”
In Greenwich, it does.
Chimney cap installation helps protect the flue from rain, snow, nesting animals, debris, and downdrafts caused by coastal winds. Caps reduce moisture entry, protect liners, and help stabilize airflow during storms and seasonal shifts.
In areas with shoreline exposure and mature trees, a missing or damaged cap is often the starting point for blockages and leaks.
A chimney cap is a simple layer of protection that supports the entire system.
Chimney Installation
“What If My Chimney Was Never Built for This Climate?”
Some chimneys—especially older or poorly constructed ones—weren’t designed to meet modern safety standards or withstand Greenwich’s coastal environment. In those cases, partial rebuilding or full chimney installation may be the safest long-term solution.
Proper chimney construction accounts for foundations, liners, flashing, crowns, and caps working together to manage heat, airflow, moisture, wind load, and freeze–thaw cycles common along the Sound.
A chimney should be built for where it lives, not just how it looks.

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.

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.
