Chimney & Fireplace Services in New London, CT — Steady, Skilled Care for Safety
Chimney Inspection
“How do I know if my chimney actually needs a checkup?”
Homeowners often wonder this when everything seems fine. The truth is, many chimney problems hide where you can’t see them—like minor creosote buildup, small liner gaps, or moisture starting to seep into the crown.
During an inspection, we check the flue, liner, smoke chamber, crown, masonry joints, flashing, and damper operation. This full approach ensures nothing is overlooked.
Earlier this year, a chimney looked perfect from the living room, but inside, the liner had begun separating. Catching it early meant a simple repair instead of a major rebuild.
Upshot: Understanding what’s happening inside your chimney is the most reliable way to prevent hidden issues.
Chimney Repair
Are Tiny Cracks Really Something to Worry About?
Small cracks often look harmless at first. But even narrow openings can allow heat, smoke, and moisture to travel where they shouldn’t. Over time, seasonal temperature swings and repeated exposure to water can widen those cracks, slowly weakening the chimney’s structure from the inside out.
In the Montville Street area, we addressed minor liner cracks and repointed aging mortar before moisture had a chance to spread. Installing a new crown and cap sealed the system and helped protect it from future exposure.
Upshot: Catching cracks early keeps routine repairs from turning into structural concerns.
Chimney Cleaning
If I Barely Use My Fireplace, Is Cleaning Still Necessary?
Even light fireplace use creates creosote. Add moisture, debris, or nesting material, and airflow can become restricted without any obvious warning. That’s often when homeowners start noticing odors, smoke backing into the room, or uneven burns.
Near Hempstead Street, we cleaned a chimney in a historic home that hadn’t been serviced in years. Thick creosote buildup inside the flue was limiting draft. After cleaning, airflow improved, the fireplace burned cleaner, and the homeowner felt comfortable using it again.
Upshot: Regular cleaning keeps your chimney operating safely, even if it’s only used occasionally.
Chimney Maintenance
What Does Regular Chimney Maintenance Actually Do?
Maintenance is about prevention. It focuses on identifying small issues—worn seals, early crown damage, loose caps, or minor moisture entry—before they turn into repairs.
During a routine visit near City Hall, we noticed early flashing deterioration. Replacing the flashing and sealing small gaps prevented water intrusion during the next heavy storm.
Upshot: Consistent maintenance helps keep chimney issues predictable and repair costs manageable.
Level 2 Chimney Inspection
When Is a Level 2 Chimney Inspection Necessary?
Level 2 inspections are recommended after severe weather, appliance changes, or during real estate transactions. Using camera equipment, we inspect liner joints, offsets, and flue surfaces that aren’t visible during a standard inspection.
Near Fort Trumbull, a homeowner requested a Level 2 inspection before selling their home. We discovered a hidden obstruction caused by bird nesting, corrected the issue, and documented the repair—allowing the sale to move forward without delays.
Upshot: A deeper inspection provides clarity when conditions change or decisions depend on chimney safety.
Chimney Crack Repair
How Does Chimney Crack Repair Actually Work?
Chimney cracks don’t all mean the same thing. Some affect surface masonry, while others run deeper into the liner or smoke chamber. The key is understanding where the crack is, why it formed, and whether it’s allowing heat, smoke, or moisture to move into areas it shouldn’t.
In a home near Montville Street, what looked like simple exterior cracking turned out to be early liner separation caused by freeze–thaw pressure. We stabilized the liner, repointed the surrounding mortar, and sealed the crown to stop water from feeding the problem. Addressing the cause—not just the visible damage—helped restore safe draft and prevented further deterioration.
Takeaway: Effective crack repair isn’t about patching what you see—it’s about correcting the conditions that caused the crack in the first place.
Chimney Leak Repair
How Can I Tell If My Chimney Is Leaking?
Chimney leaks aren’t always obvious right away. Musty smells, rusted components, or ceiling stains are often the first signs. In coastal areas, leaks commonly originate from damaged crowns, failing flashing, or missing caps.
Near Burritt Street, a homeowner dealt with recurring ceiling stains despite previous roof repairs. Once the chimney crown was sealed and the flashing corrected, the issue stopped completely.
Upshot: Identifying the true source of a leak early prevents water damage from spreading.
Chimney Cap Installation
Do I Really Need a Chimney Cap?
Chimney caps help keep rain, animals, and debris out of the flue while also improving draft and reducing downdrafts.
At a waterfront home on Arch Street, repeated bird nesting had become a recurring issue. Installing a stainless-steel cap solved the problem immediately and noticeably improved airflow.
Upshot: A properly fitted cap offers simple, year-round protection for your chimney.

After searching for a chimney sweep company that were available to diagnose and repair before the inclement weather arrived, was extremely difficult. But GMT were able to arrive that same night.

CO leaking in and unable to stay in my home. GMT secured the work done the very next day. My family and I were able to come back home after one night out. They were professional and fast in freezing temperatures. Town inspection passed. Service you can count on. Definitely reliable and compassionate.
