According to the CSIA, problems in your chimney’s flue can present serious risks to your home and family, because it’s no longer able to perform its primary function: to safely contain and vent the products of combustion to the outside of your home. If your current liner was installed improperly or is deteriorating, it is highly recommended that you either have a new one installed by a licensed professional or have your current liner repaired (if possible). There are several different relining options, depending on both the type of flue liner you currently have and the overall condition of your flue.
Stainless Steel Liners
The vast majority of newer homes have chimneys with stainless steel chimney liners already installed. These liners come in two different forms: rigid and flexible. The type your technician will choose ultimately depends on the shape of your chimney. A rigid liner will be ideal only for chimneys that are straight with no offsets or bends, whereas a flexible liner is ideal for chimneys that are less than straight. Rigid liners are available in diameters ranging from 3-10 inches, while flexible liners run from 2-10 inches in diameter. A huge selling point for stainless steel liners, in general, is that they come with a lifetime warranty.
Because they resist rust and easily hold and move heat and smoke up through the house and out into the atmosphere, you can expect many years of problem-free use out of stainless liners. Stainless liners are an affordable alternative to most traditional chimney liners. Replacing your existing liner with a new stainless steel liner is a wise choice.
HeatShield is a chimney liner repair system that eliminates the hazards and draft problems caused by gaps, cracks, and spalling in otherwise sound masonry chimneys. It is a specially formulated “cerfractory” coating, which combines the strength of a high-fired ceramic with the heat resistance of high temperature refractory cement to restore the integrity of your chimney’s flue. This restored integrity allows your flue to properly vent hazardous flue gases up and out of your home. Developed in Europe over 20 years ago, HeatShield has been independently tested and has been found to exceed all American Society for Testing and Materials (ASTM) and Underwriters Laboratories (UL) Outlines of Investigation for chimney repair and resurfacing products.
HeatShield provides several options to address varying degrees of chimney liner deterioration:
- Joint Repair System—recommended for the repair of defective mortar joints
- Resurfacing System—recommended for cracked or spalling chimney liners
- CeCure Sleeve Relining System—recommended for chimneys with more serious defects or those that are unlined
Your certified chimney professional will be able to let you know which option is best for your particular job depending on the severity of the identified defects. Each of the available options will help restore your chimney to its original peak level of safety and efficiency in a very timely and cost-effective manner.
