Joe and Alex had my gas fireplace up and running in minutes, and they were so pleasant and professional. A smile and a handshake plus excellent service go a long way in customer satisfaction. I highly recommend GMT.

The staff at GMT are professional, well educated, dog friendly, flexible with scheduling and ensure priority to jobs that need it. They use USA made products sourcing from the local community, offering lifetime warranties on most of their products, while also still maintaining very reasonable pricing. Their customers safety and satisfaction are first and foremost and it shows throughout their whole team. Joe came out on a Sunday for my estimate and by Friday of the same week I had my chimney lining replaced, everything detailed cleaned, and a new cap installed.

Common Questions

GMT Chimney Services provides comprehensive chimney cleaning including traditional sweeps to remove soot and creosote buildup, flue cleaning with chemical methods for tough glazed creosote, and deep cleaning using professional chemical removal (PCR). They also specialize in smoke chamber cleaning to improve draft, pellet stove cleaning for efficient burning, and humane animal removal for birds, squirrels, or raccoons from chimneys. These services follow NCSG and NFPA standards to prevent fire hazards and ensure smooth airflow in Connecticut homes.
With over a decade of experience, GMT Chimney Services has repaired chimneys across Connecticut, handling freeze-thaw damage in northern areas like Torrington and coastal moisture issues in places like Bridgeport. Their licensed technicians perform structural repairs, crack pointing with fresh mortar, flashing resealing, and crown repairs to restore strength and prevent leaks. All work is insured and backed by guaranteed customer satisfaction to protect homes from harsh weather.
GMT Chimney Services serves a wide range of Connecticut areas including Hartford, New Haven, Middletown, New Britain, Norwich, Danbury, Torrington, Windsor Locks, Bridgeport, Stamford, Norwalk, and communities in Litchfield, Fairfield, and New Haven Counties. They offer Level 1 basic annual inspections for routine maintenance and Level 2 camera-assisted inspections recommended after damage or property sales. Certified inspectors identify hidden issues like creosote buildup or structural weaknesses to ensure year-round safety.
A Level 2 inspection by GMT involves camera-assisted examination of the entire chimney system, including the flue, smoke chamber, and liner, to detect hidden damage or hazards not visible in a basic sweep. It's ideal after events like storms, fires, or home sales, and currently offered free until March 31, 2026, when booking through their site. Technicians provide a detailed safety report with recommendations for repairs or maintenance to comply with NFPA standards.
For coastal areas like Stamford and Norwalk facing salt air and heavy rains, GMT applies pro-grade sealants for chimney waterproofing and repairs leaks by locating sources in flashing, crowns, or masonry. They reseal roofline flashing and restore chimney caps to block water entry, preventing interior damage from moisture. These solutions protect against years of exposure while meeting safety codes for long-term durability.
GMT Chimney Services installs stainless steel or clay chimney liners for efficient venting, along with flue systems, wood or pellet stoves, dampers, rain caps, and roof flashing to create tight seals. In historic New Haven County homes, they ensure installations meet code for safety and energy efficiency, including insulation to boost draft performance. Professional setups prevent issues like leaks or poor airflow from the start.
In Litchfield County's snowy winters, GMT provides fireplace cleaning, ash removal, wood stove inspections, draft testing, and efficiency tune-ups to reduce smoke and creosote buildup. They replace glass doors and gaskets while checking fireboxes and dampers for safe operation per NCSG guidelines. This proactive maintenance extends system life, minimizes fire risks, and keeps heating efficient for cozy cabins and homes.
