The chimney liner is the component that makes a chimney safe to use in Markham. It contains combustion gases within the flue and prevents them from migrating into the surrounding masonry and the home structure in Markham, IL. It protects the surrounding chimney masonry from the heat and corrosive byproducts of combustion in Markham. And it provides a correctly sized flue cross-section that produces the draft performance the connected appliance was designed to operate with in Markham, IL.
A liner in good condition performs all three functions with every use. A liner that is cracked, deteriorated, incorrectly sized, or absent does not in Markham. And the consequences are not performance issues. They are safety issues in Markham, IL. Affordable Chimney performs chimney relining throughout Markham — camera inspection before any recommendation, correct liner type, correct sizing, licensed installation, guaranteed in Markham, IL.

Chimney relining is the installation of a new liner system within an existing chimney when the original liner has failed, is incorrectly sized for the current appliance, or was never present in Markham. The new liner creates a correctly sized and correctly sealed flue path from the appliance connection at the firebox level to the chimney top in Markham, IL. It restores all three liner functions — combustion gas containment, masonry protection, and correct draft performance — that a failed or absent liner cannot provide in Markham. A chimney with perfectly maintained exterior masonry but a failed liner is not a safe chimney in Markham, IL.
Your chimney needs relining when the existing liner has cracked beyond what repair can address in Markham, IL. When a new appliance is being installed that requires a different liner specification than the existing one in Markham. When the chimney is being converted from wood-burning to gas operation in Markham, IL. When the chimney has no liner because it predates the standard requirement for liners in Markham. And after any chimney fire that has damaged the existing liner beyond what camera inspection confirms can be safely repaired in Markham, IL.
The chimney liner performs three functions that are all safety-critical in Markham, IL. It contains combustion gases including carbon monoxide, carbon dioxide, and other byproducts within the flue, preventing them from migrating into the surrounding masonry and from there into the home's living spaces in Markham. It protects the chimney masonry from the heat of combustion, which at 1,000 degrees Fahrenheit or above in an active fire is significantly higher than the surrounding masonry's design temperature in Markham, IL. And it provides a correctly sized flue cross-section that produces the upward draft needed to carry combustion gases out of the home rather than allowing them to back up into the firebox and living space in Markham. A compromised liner fails at one or more of these functions with every use in Markham, IL.
A chimney liner with cracks is not simply a deteriorated component in Markham. It is an active pathway for combustion gases to migrate from the flue into the surrounding chimney masonry and from there into the wall cavities and living spaces of the home in Markham, IL. Combustion gases from a wood-burning fireplace include carbon monoxide, carbon dioxide, water vapor, and various organic compounds in Markham. None of these belong in the home's living spaces in Markham, IL. A cracked liner allows all of them entry into the building assembly with every fire in Markham.
Carbon monoxide is the combustion gas that makes a damaged liner most immediately dangerous in Markham. It is colorless and odorless. It produces symptoms including headache, dizziness, nausea, and confusion that are frequently mistaken for other illnesses in Markham, IL. At sufficient concentrations it is fatal in Markham. A cracked liner on a gas appliance is particularly dangerous because gas combustion produces a higher proportion of carbon monoxide when draft is impaired by liner damage in Markham, IL. Every home with a fuel-burning appliance should have a working carbon monoxide detector in Markham. And a damaged liner warrants immediate assessment and repair before the appliance is used again in Markham, IL.
If camera inspection has confirmed liner damage, or if you have reason to believe the liner may be damaged from a recent chimney fire, do not use the fireplace until the liner has been assessed and repaired or replaced in Markham, IL. The risks from a damaged liner are not performance risks that can be tolerated until a convenient repair date in Markham. They are safety risks that accumulate with every fire lit through a compromised liner in Markham, IL. Call Affordable Chimney for fast assessment in Markham.
Any confirmed chimney fire warrants camera inspection of the complete liner before the fireplace is used again in Markham, IL. Chimney fires burn at temperatures exceeding 2,000 degrees Fahrenheit in Markham. Clay tile liners expand significantly at these temperatures and contract rapidly as the fire dies and the chimney cools. The rapid thermal cycling cracks tile sections and separates mortar joints between them in Markham, IL. The damage may be invisible from the firebox opening or from a partial visual inspection in Markham. Full camera inspection of the complete liner is the only reliable way to assess chimney fire damage in Markham, IL. If inspection reveals cracking or displacement of liner sections, relining is the correct response before the chimney is used again in Markham.
Different appliances have different liner requirements in Markham. A new appliance installed on an existing chimney may require a different liner size or liner type than what currently serves the chimney in Markham, IL. A gas insert installed on a chimney with an existing clay tile liner typically requires a correctly sized stainless steel liner because gas appliances need a smaller, insulated flue to maintain correct operating temperatures in Markham. Affordable Chimney assesses liner compatibility with every new appliance installation and recommends relining where the existing liner does not meet the new appliance's requirements in Markham, IL.
Converting a wood-burning fireplace to gas operation almost always requires relining in Markham, IL. The existing clay tile liner in a wood-burning chimney is typically significantly oversized for the smaller liner cross-section that gas appliances require in Markham. A gas insert on an oversized masonry flue without a correctly sized liner produces condensation in the flue from the water vapor in gas combustion gases that the cool, oversized flue cannot exhaust efficiently in Markham, IL. That condensation corrodes the flue and produces moisture problems in Markham. A correctly sized stainless steel liner installed within the existing masonry chimney provides the correctly sized flue the gas appliance requires in Markham, IL.
A clay tile liner with significant cracking confirmed through camera inspection warrants relining in Markham. The threshold between liner repair and liner replacement depends on the extent and distribution of the cracking in Markham, IL. Minor to moderate cracking that has not compromised the liner's overall structural continuity may be addressed through cast-in-place resurfacing in Markham. Severe cracking, displaced tile sections, or cracking distributed across a significant proportion of the liner length warrants full relining in Markham, IL.
Many older homes in Markham, IL were constructed with chimneys that have no liner in Markham. Pre-1900 construction in many areas predates the standard requirement for chimney liners in Markham, IL. An unlined chimney exposes the surrounding masonry directly to combustion gases, heat, and moisture in Markham. Current building codes require a liner for any fuel-burning appliance in Markham, IL. Affordable Chimney installs correctly specified liners in unlined chimneys across all configurations throughout Markham, bringing older chimney systems up to current safety and code standards in Markham, IL.

A liner cross-section smaller than correct for the specific firebox or appliance restricts draft and produces smoke intrusion during fireplace use in Markham, IL. The restricted flue cannot carry combustion gases away from the firebox fast enough, allowing some to spill into the room in Markham.
A liner cross-section larger than correct for the specific appliance dilutes the hot flue gases, reducing the temperature differential driving natural draft in Markham. The result is weak draft and, for gas appliances, excessive condensation from the water vapor in gas combustion gases that the cool, oversized flue cannot exhaust efficiently in Markham, IL. Condensation corrodes the liner and produces moisture problems in Markham.
Liner sizing based on the chimney's external appearance or the appliance type without specific measurement produces approximations that may not be correct in Markham.
