Combat Deterioration, Erosion & Other Risks

A Safe & Sound Investment

There are three main types of chimney liners. These include clay tile liners, cast-in-place liners, and metal liners. All three types provide adequate protection, however, the liner that is appropriate for your home should be determined by a professional.

With fire prevention and home safety a top priority, there are a few reasons why you may need a new liner: If your chimney has no liner, if it was installed improperly, or if it’s deteriorating or defective. Also, homes built prior to the 1940’s were typically built without a chimney liner, which led to more chimney and house fires for homes from this era.

Combustible creosote or soot can also escape through these openings and build up outside the chimney flue liner. If creosote were to catch fire in this area of your chimney, it can cause serious damage. This type fire can no longer be contained within the flue.

Blockage in a furnace flue is extremely hazardous because it can cause carbon monoxide fumes to enter your home. One of the most common problems that can occur with chimneys is blockage, regardless of what type of furnace fuel is used.

Your certified chimney specialist will be able to show you pictures and explain in detail the reasons you need a fireplace liner. Understanding the reasons, a liner is recommended is going to help you make the best investment decision for your home and your peace of mind.

Advanced technology such as the “Chim Scan” has become a standard in our industry and the pictures are now clearer and more defining than ever. Chimney fires can destroy the integrity of the fireplace flue. Deterioration is commonly caused by age, moisture and poor maintenance. Other sources of damage can be animals, lightning and strong storms that cause damage you may not notice without a professional inspection.


In order to take proper care of your chimney, a furnace flue inspection should be scheduled:

  • At least once per year
  • Before moving into a new home
  • Before the installation of a new furnace

Furnaces, boilers, and hot water tanks exhaust large quantities of water vapor during the normal combustion process of natural gas. Oil and gas furnaces produce by-products which can erode the flue lining. Any type of furnace liner that is breached can cause a fire, since heat can reach combustible parts of the home.

Clay liners that have gaps or cracks, allow this moisture into the interior structure which eventually deteriorates the masonry structure from the inside out. Additionally, gases vented from gas burning appliances can escape the lining and migrate into the home.

When we install a fireplace flue liner, we use only the best stainless-steel flexible fireplace liner available on the market today. The liner is kept in place with “Thermix” insulation, which is an industry standard and tested insulator. The insulation is mixed with water on site and poured into the void between your new liner and the surrounding chimney.

The next step is removing the obsolete throat damper so we can “parge” the smoke chamber and install a new energy efficient Top Damper. This process guarantees that your fireplace flue is in optimum condition for burning wood. The fireplace liner has a lifetime warranty with regular inspections.


Chimney PargingParging simply means applying a coat of Refractory Mortar to the brick surfaces of the chimney’s smoke chamber to make the surface smooth. The smooth surface allows the smoke to draft up the chimney more efficiently.

Refractory cement fills in any cracks or holes that may have existed in the smoke chamber, ensuring your chimney meets the standard for clearance to combustibles. This is the heat protection you need for the hottest section of your fireplace.

Now that the chamber is sealed and the fireplace liner is in place, smoke can flow smoothly up the chimney. There are no cracks or holes to endanger your home from heat, sparks or flue gasses.
