Reline Your Chimney For A Safer Fire
A chimney liner is the inner face of your chimney, and it is just as important as the chimney’s exterior for keeping your chimney functioning properly. Chimneys haven’t always been lined, but extensive safety tests over the past century have proven unlined chimneys to be very unsafe. For this reason, codes in most states and cities today mandate the lining of all masonry chimneys.
- Clay tile liners
- Ceramic liners
- Stainless steel liners
- Cast-in-place liners
What Does A Chimney Liner Do?
A liner serves many purposes:
1) First and foremost, the job of a chimney liner is to provide a safe and smooth passageway for the products of combustion—including toxic gases—to travel out of your home.
2) A liner protects your home from the transfer of heat. Woodwork adjacent to your chimney is far less likely to catch fire if you have an adequate liner in place.
3) A liner will protect your chimney masonry from deteriorating, which is what will happen if the acidic byproducts of combustion are allowed to eat away at your mortar joints.
4) A liner can create the perfect flue size so that your chimney will experience optimum efficiency and drafting. This is an added bonus, as many chimneys are constructed with improperly sized flues that cause many problems for homeowners down the road.
5) Finally, a chimney liner may prevent water intrusion into your chimney, should your masonry begin to take on water. Even if your brick and mortar begin to absorb water, as is the case when a chimney is not waterproofed, the inside of your chimney will remain largely impervious to water damage if properly lined.
What Kind Of Chimney Liner Do I Need?
The best chimney liner for you will depend on whether or not you already have a liner in place, what your budget is, and what type of chimney and heating appliance you have. We typically find that older masonry chimneys already have clay tile liners in them, though these liners tend to crack over time, no thanks to the expansion and contraction that occurs with a rapid temperature increase.
If you have a clay liner that’s damaged, it may not be necessary for your chimney to be completely relined. Depending on the extent of the damage to your flue, many times we are able to use a product called HeatShield®, which does an exceptional job at resurfacing and repairing a chimney’s interior.
Should we determine that a completely new liner is your best option, we will probably recommend a stainless steel liner for upgrading your chimney. These liners are very versatile, working well with most any type of appliance and fuel type, and they are also proven to be durable and safe.
