Chimney Liner Repair

The Key to Chimney Performance: The Liner

Your chimney needs a liner in order for the system to run safely and efficiently. The liner has a few different jobs that are important to keep the chimney working for you.

  1. The chimney liner protects the home from heat transfer from the chimney. Heat transfers to materials that support the home. This heat can weaken these materials and cause a fire hazard over a period of time.
  2. The chimney liner protects the masonry from corrosive byproducts that can damage the masonry if left uncleaned. Soot and creosote becomes especially detrimental to the chimney’s masonry if allowed to mingle with moisture. Moisture can result due to a chimney leak or humid weather.
  3. The chimney liner keeps hazardous gases and chemicals from leaving the chimney and entering the home. Hazardous gases affect the air quality and health of the family. The chimney’s masonry is porous in order to allow gas to escape and assist with the efficiency of the chimney. The liner prevents the gases from escaping into the house.

Should You Repair or Replace Your Liner?

It might be that you don’t need a completely new liner, but just a repair. Many old homes may still have a damaged clay tile liner. The stainless steel liner is rated for use with all fuel types, and built to last. The industry now has a repair option that offers the same result as a stainless steel liner and Magic Sweep specializes in this type of liner repair.

Introducing HeatShield®

Industry professionals have formulated a special “Cerfractory®” sealant that combines ceramic and refractory materials. This is used to completely restore a damaged or outdated clay liner. This system eliminates the dangers caused by gaps, cracks, and spalling in your chimney. HeatShield’s® Cerfractory® technology is proven to withstand moisture, corrosive, flue gases, and temperatures over 2900°F. It surpasses both National Fire Prevention Association (NFPA) and International Residential Code (IRC) which require only a “Medium-Duty” refractory mortar for use in fireplaces and chimneys.

Hiring a HeatShield® Expert to Repair Your Liner

Independent HeatShield® Installers are factory trained, and experienced with materials and specially designed tools. The technician will first apply the sealant. Then the technician uses special video cameras to verify repairs were completed properly and that the chimney will be able to return to full function.

In addition to all the benefits that HeatShield® offers, it is an “eco friendly” product. Because it is made from recycled and naturally occurring materials, so it saves on resources as well as time and money. If that is not enough to convince you to choose HeatShield® for your liner repair, then remember the 20-year material warranty.
