Chimney Inspection
Do I Really Need a Chimney Inspection?
Many homeowners assume that if the fireplace lights and smoke goes up, everything must be fine. But some of the most serious chimney issues stay hidden deep inside the flue or behind the masonry.
During an inspection in Fair Haven, a homeowner mentioned light smoke drifting into the room on colder nights. The chimney looked solid from the outside. Inside, however, the liner had partially collapsed, and an animal nest was restricting airflow. Without an inspection, the issue would have continued quietly—raising the risk of carbon monoxide exposure and interior damage.
A proper chimney inspection looks beyond the surface. It helps identify creosote buildup, liner damage, moisture intrusion, and airflow issues early—when they’re easier and safer to address.
Chimney Repair
Are Small Cracks in My Chimney Dangerous?
Cracks in chimney masonry often seem harmless at first. In reality, even small openings allow moisture to enter. Once winter temperatures drop, that moisture freezes, expands, and slowly breaks the structure apart from the inside.
In East Rock, we inspected a chimney with barely noticeable liner cracks. Over time, moisture had worked its way behind the brick, threatening the interior walls. Repointing the mortar, rebuilding the crown, and installing a cap stopped the damage before it spread further.
Early repairs don’t just protect the chimney—they protect the home around it.
Chimney Cleaning
Why Chimney Cleaning Is About More Than Soot?
Chimney cleaning isn’t cosmetic maintenance. It’s a safety measure.
Creosote builds up gradually with regular fireplace use. When it thickens, airflow becomes restricted, smoke struggles to exit properly, and the risk of chimney fire increases.
In Westville, we cleaned a chimney that hadn’t been serviced in years. Heavy creosote lined the flue, causing poor draft and smoke issues. Once cleaned, the fireplace burned more efficiently, smoke problems disappeared, and the homeowners felt confident using their fireplace again.
Regular cleaning keeps the system breathing the way it should.
Chimney Maintenance
How Routine Maintenance Prevents Costly Repairs?
Chimney maintenance focuses on the parts homeowners rarely think about—crowns, flashing, caps, liners, and mortar joints. These components quietly protect the home from water, heat loss, and structural damage.
Near Amity Road, early signs of flashing deterioration were caught during a routine visit. A simple repair prevented water from reaching insulation and ceilings, avoiding a much larger repair down the line.
Consistent maintenance keeps small issues from turning into expensive surprises.
Level 2 Chimney Inspection
When a Level 2 Inspection Is the Right Call?
Some situations call for a deeper look. Home sales, appliance changes, and storm damage often require a Level 2 chimney inspection, which includes internal camera scanning and detailed documentation.
In West River, a homeowner preparing to sell requested a Level 2 inspection. Video footage revealed a hidden flue obstruction caused by nesting birds. Once addressed and documented, the sale moved forward without delays or safety concerns.
Level 2 inspections bring clarity when decisions depend on chimney condition.
Chimney Crack Repair
How Do Chimney Crack Repairs Work?
Cracks in masonry or liners affect both safety and performance. Repairs may involve repointing mortar, restoring crowns, or addressing liner damage—each tailored to the chimney’s condition.
Near Quinnipiac Meadows, multiple hairline cracks were compromising proper draft. Targeted repairs and a new cap restored safe airflow and protected the structure from further weather exposure.
Timely repairs help extend the life of the chimney and keep it working as intended.
Chimney Leak Repair
What Causes Chimney Leaks and How Are They Fixed?
Chimney leaks usually start at the crown, flashing, or porous masonry. Left untreated, even small leaks can lead to staining, mold, and interior damage.
In Wooster Square, ceiling stains appeared after heavy rain. Repairing the crown, replacing flashing, and waterproofing the masonry stopped the leaks completely before winter arrived.
Fixing the source matters more than treating the symptoms.
Chimney Cap Installation
Why Chimney Caps Matter More Than Most Realize?
Chimney caps protect against rain, animals, debris, and downdrafts. Without one, chimneys are vulnerable year-round.
In East Shore, a missing cap allowed wildlife to nest inside the flue. After installing a stainless-steel cap with a spark guard, the chimney was fully protected and drafting properly again.
A simple cap often prevents some of the most common chimney problems.

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!
