HeatShield® Gives You Options when Relining a Chimney
Your chimney may look perfect on the outside, but just like you can’t judge a book by its cover, you can’t judge the condition of a chimney based on how it looks from your driveway. It’s what’s inside that counts. To determine the true condition of your chimney, you should have a chimney professional look inside and inspect it for hidden damage such as cracks and gaps in the liner. The best way to accomplish that is with a level 2 fireplace and chimney inspection which includes a 360 degree look at the inner chimney flue wall from firebox to the top of the flue.
If your chimney liner is damaged, HeatShield® chimney liner repair is an option to restore the liner without having to go to the considerable expense of rebuilding the flue or relining it with a stainless steel liner.
The HeatShield® system can be used to repair missing mortar joints. It is extremely dangerous to burn a fire in a chimney that has missing mortar joints. Once your chimney is inspected, your technician will be able to diagnose whether or not your chimney is missing these important joints.
HeatShield® can also be used to resurface the entire flue system of your chimney. If your chimney inspection reveals widespread cracks, missing mortar joints and spalling flue tiles, a complete resurfacing may be recommended.
How it works
HeatShield® uses a specially-formulated Cerfactory® sealant material that restores your chimney flue. The HeatShield® material is applied by attaching a custom-sized foam applicator to the bottom of the chimney. The applicator is pulled from the bottom to the top of the chimney. The first pass applies the “tie coat.” This cleans any dust and debris from the chimney. Next, the special Cerfactory® sealant is applied. The foam insert “squeegies” the sealant up the flue, filling the cracks and holes. Once the sealant has dried, the repair must be inspected.
While HeatShield® is an excellent option for some chimney repairs, it is not the right choice for all chimneys. Every chimney is unique and each repair project will have its own set of issues and challenges. Your Chimney Sweeps technician will do a thorough evaluation of your chimney and determine the product or service that is right for your home.
Regular service and maintenance to your fireplace and dryer vent systems will help keep it off our “worst chimneys ever” list.
