Connecticut Chimney Installation by Licensed & Experienced Experts

Done Right, The First Time

At GMT Home Services, we know a chimney is more than a decorative feature — it’s the backbone of a safe, efficient, and comfortable home. Whether you’re building from scratch, replacing an existing chimney, or upgrading to meet modern safety standards, our Connecticut-based team delivers expert chimney installation with precision and care.

With decades of combined experience and deep knowledge of New England building codes, we ensure your new chimney not only looks great but also performs flawlessly for decades to come.

Prefab or Masonry Chimney Installation?

We help Connecticut homeowners choose the right system:

Prefab (factory-built) fireplaces: Cost-effective, quick to install, ideal for adding warmth and ambiance in days.

Masonry fireplaces: Longer to build but offer timeless charm and unmatched durability.

Breathe New Life into Your Space: Whether you’re switching to gas or refreshing the facade, a fireplace remodel instantly transforms the look and feel of your room.

Safety Meets Convenience: A gas upgrade means less maintenance, no firewood hassle, and cleaner, safer operation.

More Heat, Less Waste: Modernized fireplaces retain more heat, boosting comfort and energy efficiency — small changes with big benefits

Chimney Liner Installation – Your First Line of Defense

We provide professional chimney liner installation across Connecticut, improving draft efficiency, and protecting against heat and corrosion — all built to withstand New England’s harsh winters.

Purpose & Safety: Directs smoke, gases, and combustion byproducts safely out of your chimney flue and home, while protecting masonry from extreme heat, combustible materials, corrosive creosote, and moisture damage.

Efficiency Gains: Improves heat retention during a hot fire, enhances draft performance, and helps lower fuel costs.

Material Options: Stainless steel for durability, stainless steel liner clay flue tiles for traditional masonry builds, and modern insulated liners for cold climates.

Proper Sizing: Prevents smoke backup from undersized liners and avoids weak drafts from oversized liners.

Installation Standards: Seamless joints, secure fittings with screws, and insulation where required to meet Connecticut building codes.

Ongoing Care: Annual inspections recommended to detect wear, creosote buildup, or structural issues early.

Chimney Cap Installation – Small Part, Big Protection

A precision-fit chimney cap protects your home year-round. We custom-measure and install chimney caps made of durable materials that can stand up to New England winters.

Weather Protection: Deflects rain, snow, and wind-driven debris, preventing rust, moisture damage, and masonry decay.

Animal Guard: Keeps birds, squirrels, raccoons, and other wildlife from nesting in your flue or stovepipe.

Design & Material Options: Single-flue or multi-flue caps in stainless steel or copper for maximum strength and style.

Mesh Standards: ¾-inch mesh — tight enough to trap embers, open enough for good airflow.

Winter Ready: Rain guards and wind-resistant styles to keep your draft steady during Connecticut’s cold months.

Long-Term Savings: Prevents costly repairs, protects liners, and extends chimney life.

Chimney Maintenance Secrets Every Connecticut Homeowner Should Know

Schedule annual chimney inspections to catch cracks, loose mortar, or liner damage early.

Repair or replace your liner promptly to protect your home from heat and corrosive gases.

Install a stainless steel or copper chimney cap to block water, debris, wildlife, and embers.

Trim chimney liner flush with the top plate collar for a code-compliant fit.

Check caps and flashing after storms to maintain weatherproofing.

Frequently Asked Questions (FAQs)

1. What tools do I need for a proper chimney installation?

Chimney installation requires precision and safety. You’ll need a razor knife, screwdriver, caulk gun, gloves, safety glasses, and — if installing a chimney liner — a power drill. To trim the liner clean, you’ll use a grinder or Sawzall to cut the excess material flush with the top plate collar.

2. Why is the right chimney liner so important for safety and efficiency?

A properly installed chimney liner channels smoke and combustion gases out of your home and away from combustible materials. It also boosts draft efficiency and saves you money on heating. Fixing smoked or damaged liners now can prevent bigger problems later.

3. How do chimney caps protect my home?

Chimney caps—usually made of steel or copper mesh—keep out rain, snow and wildlife, while ensuring the liner is protected . They’re installed directly over the flue opening and have a ¾-inch mesh, enough to stop embers but still allow airflow.

4. What clearances do I need with a chimney installation?

Compliance with clearances is key:

1. 36 inches from stoves to combustibles.

2. 18 inches from pipes to combustibles.

3. 1-inch air gap when using asbestos millboard.

4. Chimney height follows the 3-2-10 rule (3 ft above roof, 2 ft higher than nearby 10 ft structures).

5. How much floor protection do I need under a wood stove?

According to UL 1482, you need to extend non-combustible floor protection 16 inches in front and 8 inches to each side of the stove. Adding a 2-inch layer of sand or ash in the stove base can also help prevent overheating.

6. How often should I schedule chimney cleaning and inspections?

Both cleaning and inspections are recommended annually to prevent creosote buildup—a major cause of chimney fires—and catch damage early . If you burn a lot of wood or think you have excessive residue, you may need to clean twice a year

7. How can I reduce creosote buildup in my chimney?

Use well-seasoned hardwood to burn cleaner and hotter, which reduces tar-like creosote deposits. Cleaning regularly and keeping fires hotter (especially at ignition) helps prevent buildup and fire risk

8. What are the signs my chimney needs maintenance or repair?

Look for:

1. Smoke backing into the room

2. Animals nesting inside

3. Heat or odors escaping from masonry These signs mean creosote buildup, cracks or blockages—get inspected and repaired to keep your home safe

We had a great experience with Joe and team. Very responsive and thorough - he provided a detailed estimate on all the work needed to be done (we needed a complete rebuild from roofline). The team did a great job and are clearly very good at what they do. They were in and out in two days and their quote was beyond reasonable. Highly recommend.

I had a great experience with GMT Chimney Services. They were extremely responsive and able to come out quickly when I needed help after a bird got stuck in my chimney (thankfully it was fine!). They cleaned my gas fireplace, removed bird nesting and debris from the chimney pipe, and installed a new cover to prevent future issues. The team was professional, neat, and made sure everything was cleaned up before they left. Overall, they were easy to work with and did a thorough job. I would definitely recommend them to anyone needing chimney or fireplace services.

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.

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. GMT estimated and fixed my whole situation before the snow touched the ground. I had an emergency situation with a roof replacement I previously had with another company gone bad. 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. Highly recommend.
