Gas fired heating appliances produce low temperature, high moisture content flue gas which collects as acidic condensation on the inside of oversized, cold masonry chimneys. This is the primary cause of masonry chimney deterioration which creates a serious health hazard as well as costly home repairs.
What type of material should be used for gas liners?
Liner for Wood Burning Fireplace
Aluminum, with a half century usage history, has proven to be an economical, effective material for venting gas fired equipment.
Stainless steel is highly recommended due to corrosion resistance and life span, however this is substantially more expensive.
Approval Listing?
Liners installed by Strictly Liners whether they are aluminum or stainless steel are of the highest quality available in the industry.
Listings by approved testing agencies indicate that the gas liner has undergone rigorous testing to ensure that it is suitable for its intended use.
Wood burning and oiled fired liners are of the highest quality stainless steel.
Who should install / maintain a gas liner?
WARNING: A qualified licensed gas fitter registered with TSSA is legally required to do the installation.
A qualified heating or chimney contractor with a gas license is the best person to install this type of product. There are several technical details which must be addressed before a liner is installed.
A gas liner should be checked at least once a year by a qualified technician to ensure that the system is venting properly without condensation occurring.

Chimney deterioration / Liner deterioration!
Installing a lightweight, properly sized, metal chimney liner will help create effective venting. Insulating the liner is recommended and will further enhance operation of the venting system.
Why does my Chimney need to be Rebuilt or Repaired?
This is one example of how chimneys can be deadly!
The freeze/thaw cycle causes chimneys to deteriorate which in turn leaves a very deadly situation to anyone passing below.
i.e. Bricks / Capping falling off onto the persons head below!
i.e. Water damage to the inside of the home!
What are your repair options?
A cost efficient way is to rebuild above the flashing level and cap off with a factory chimney extending to meet Code Standards.
Remove the chimney and rebuild it with a matching brick to the existing height.
Many things can cause a blockage in a chimney: Animals, Nests, Deterioration Falling down to the breach and blocking the venting.
Collapse flue tiles
Vermiculite will deteriorate liners, which results in a blockage of the vent. (Vermiculite in the past was used to insulate liners - this is a health concern now - If your home is over 10years old please call for an evaluation if you are concerned.)
Cement Blocks / Block foundations in the past were used to insulate chimney liners - These blocks will need to be removed as this is now a safety risk.

How Strictly Liners completes a Removal?
Our certified staff will use our boom in many cases for safety reasons.
Dormant chimneys should be removed above the roof line, we will then seal up the hole and match the current roof and bricks.

Deterioration On the Exterior
Factory built chimneys are a VERY cost effective method too replace dilapidated masonry chimneys.
The chimneys will vent wood, gas and oil fired appliances.
An extended life span and warranty.
This is a superior chimney compared to masonry.
WHY you ask? Because the freeze/thaw cycle does not decay metal chimneys the same way as it does to masonry. (When properly installed)
