At GMT Home Services, we specialize in chimney flue installation and chimney liner replacement that keeps your home safe, efficient, and protected from fire hazards. Whether you’re dealing with an existing chimney that needs a new liner installed or want to add a chimney flue cap for extra protection, our certified technicians have the right tools, materials, and expertise to get the job done right.
A chimney flue isn’t just another part of your fireplace—it’s the pathway that directs smoke, combustion byproducts, and dangerous gases safely out of your house. Without proper installation, your chimney walls are exposed to high temperatures, corrosive byproducts, and creosote buildup, all of which can weaken the structure and increase the risk of chimney fires.
With a chimney liner installed inside your existing flue, you:

Every home and fireplace is different, so choosing the right flue liner matters. At GMT Home Services, we install:
Stainless steel liners – durable, resistant to corrosive byproducts, and perfect for both wood and gas-burning systems.
Clay flue liners – traditional liners often found in existing chimneys, ideal for withstanding high temperatures.
Aluminum liners – lightweight and cost-effective for certain appliances.
Our team ensures the liner is securely attached with clamps, screws, and a top plate, creating a sealed system that resists leaks and drafts.
When we install a chimney flue liner, we follow a proven step-by-step installation process using the right tools to ensure long-term safety and performance.
Inspection: Check the flue for cracks, obstructions, or damage to ensure safety.
Preparation: Use a power drill and the correct drill bit to fasten supports with masonry screws or bolts.
Liner Installation: Lower a stainless steel or clay liner into the chimney and measure it for a tight, secure fit.
Stove Pipe Connection: Attach the stove pipe or fireplace outlet to the liner, ensuring a proper seal at the damper.
Top Plate & Cap: Install a chimney cap and top plate to block rain, animals, and debris while improving draft.
Sealing & Testing: Seal the system fully, then test for smoke flow, ventilation, and resistance to leaks.
Our trained installers use clamps, screws, covers, and pipe fittings to make sure everything is tightened, secure, and built to last.

Most homeowners never see the inside of their chimney, so it’s easy to miss warning signs until a problem becomes serious. Here are a few red flags our CSIA-certified technicians often find during inspections:
Cracked or missing liner tiles – These allow heat and gases to escape into the masonry, a leading cause of chimney fires.
Smoke in your living space – If you notice smoke backing up into the room, your flue may not be venting safely.
Lingering odors after a fire – A damaged liner can trap creosote and gases, leaving a sharp, smoky smell indoors.
White staining (efflorescence) on chimney bricks – This often means corrosive byproducts are leaking through the liner.
Past chimney fire damage – Even a “small” chimney fire can destroy the protective liner.
Heavy soot despite cleaning – If buildup keeps returning quickly, it may be a draft or liner failure.
The cost to install a chimney liner depends on the materials used, the height of your chimney, and the complexity of the installation process. For example, a stainless steel liner is more durable but slightly higher in cost compared to a clay flue liner.

The cost to install a chimney flue in Connecticut typically ranges from \$1,500 to \$4,000, depending on the chimney’s height, size, and the type of liner used (stainless steel, clay, or cast-in-place). Older homes with damaged masonry may require extra work, which can raise the price.
While it’s possible for skilled DIYers, chimney flue installation is not recommended as a DIY project. Proper flue installation requires specialized tools, safety equipment, and knowledge of building codes. A poorly installed flue can cause carbon monoxide leaks or chimney fires, so it’s always safer to hire a certified professional.
The 3-2-10 rule is a chimney safety guideline: the chimney must extend at least 3 feet above the roof where it exits, and it must be at least 2 feet higher than any part of the roof within 10 feet horizontally. This ensures proper draft and prevents smoke or gases from re-entering your home.
On average, installing a flue liner costs between \$1,800 and \$3,500. Stainless steel liners tend to cost more but last longer and offer better protection. The final price depends on chimney size, roof accessibility, and whether repairs are needed before installation.
Putting a flue in an existing chimney usually costs \$2,000 to \$4,000 in Connecticut. This includes materials, labor, and any necessary preparation work. If your chimney is tall, older, or requires relining, costs may increase.
Yes, a new flue liner can be installed in most chimneys. Stainless steel liners are the most common option for modern homes because they fit inside existing chimneys, are durable, and provide excellent protection against heat and gases.
Technically, yes—but it’s strongly discouraged. Installing a flue liner requires working on the roof, handling heavy materials, and ensuring a perfect fit inside your chimney. A mistake can lead to leaks, poor draft, or fire hazards. Hiring a certified installer ensures your chimney is safe and up to code.
The cost to install a chimney liner in Connecticut generally ranges from \$2,000 to \$3,500, depending on the material. Stainless steel liners are the most popular choice because they balance durability, safety, and long-term value.
