We will immediately alert you if we discover any deficiency or problem with your liner or tile. We will take several photos to include in the inspection report for documentation. We will recommend what kind of repair is best and give an honest, fair estimate to repair. Our Chimney Professionals can install an insulated, stainless steel liner or, in most cases, repair the existing liner or tiles with the Heatshield method. 

HeatShield® LINERS

HeatShield® is a Cerfractory® sealant that our technicians use to repair damaged flue liners saving homeowners the cost of chimney relining. Our Chimney Professionals use this resurfacing system to restore chimney liners with cracks and small gaps. We recommend installing a Stainless Steel Chimney Liner for severely damaged liners or unlined chimneys.

Cracks in the flue can be a serious problem. It can allow the combustibles to escape the venting system, exposing your home to the risk of fire or the inhabitants to carbon monoxide poisoning.

Most of the time, flue liner damages go unnoticed until it is discovered during a chimney inspection or a dangerous problem occurs, like a chimney fire or fumes leaking into the living space. Normal wear and tear, improper installation, excessive heat, and gases from combustion can damage the flue liner.

Historically, the only way to fix damaged flue liners was to either break out the clay times and install a new stainless steel liner — an expensive process, however, a revolutionary product is making costly chimney liner repairs and costly replacements a thing of the past.


It's called the HeatShield® Chimney Liner Repair System, and it's approved for all fuel types. HeatShield® is a Cerfractory® flue sealant that repairs missing tiles, gaps, and cracks to restore an existing flue liner to its original safety and efficiency. It's the easiest, fastest, and most affordable method for chimney liner repairs.

Chimney Liner Repair

When a chimney is traditionally constructed, it is built using Vitreous Fire Clay flue liner (many incorrectly refer to this as terra cotta) Vitreous fire or clay tile is the most common chimney liner . These flue liners typically require frequent repair since they are prone to cracking. In addition, excessive creosote in the chimney can cause a fire that severely damages the clay tiles. You may have noticed pieces of clay in the firebox, improper draft, smoke, or fumes in the house. Your home inspector, chimney company, HVAC, or plumbing company may have mentioned a potential problem. These are all signs your chimney may need relining.

Why Your Chimney Needs a Liner

While most folks rarely notice the chimney liner, it is vital to your chimney and venting system. When you're relaxing by the warm glow of a fireplace or stove, the liner contains the heat inside the flue so that it doesn't spread and ignite nearby combustible building materials. It also helps improve heating efficiency to keep your home warm and cozy while making it easier for the smoke and harmful contaminants to vent out the chimney.

The sole purpose of your chimney liner is to contain the products of combustion and expel them out of the top of your chimney.


The flue liner deteriorates due to age, normal wear and tear, and heat. Moisture, excessive creosote, and corrosive gas residue can also accelerate its deterioration. Also, a small chimney fire can cause clay tiles to burst. Deficiencies in the liner can present a profound safety concern that may go undetected until a chimney fire occurs. 

Signs Your Chimney Needs Relining

Chimney flues are often compromised due to improper original construction or wear over time. When a chimney's flue lining is cracked, your home may be prone to gas leaks or chimney fires.

If you see the following signs, your chimney may need to be relined:

  • Pieces of clay material in the fireplace

  • Smoky fireplace

  • Drafting/combustion problems

  • Moisture/condensation buildup

  • Incomplete wood burning

  • Your fireplace/stove has a burning smell


Level 2 Chimney Inspection

The only way to know whether your chimney needs to be relined is to have it inspected. Our chimney technician uses a specially equipped video camera to scan the entire interior of the flue. We'll be able to see any cracking, imperfections, or other damages to the flue liner as we observe on a video screen in real-time.


Stainless Steel Liner

Stainless steel liners will improve heating efficiency, reduce energy costs, and are low maintenance.

Stainless steel chimney liners, either rigid or flexible, are used to repair or replace an existing chimney flue that has been compromised. It is commonly used inside a masonry chimney when the clay tiles have cracked or mortar joints have deteriorated. Stainless steel liners are also used in masonry chimneys that were built without flue tiles. Stainless Steel is the best material for the application so most liners have a lifetime warranty.
