Chimney liners serve a hugely valuable role in your chimney's ability to function at its best. They buffer nearby materials from heat, minimizing the possibility of fire, and protect the chimney's masonry from the brunt of combustion's effects, including gases that could, over time, damage mortar joints.
Imagine your home's walls without insulation -- there might be something between you and the elements, but it wouldn’t be very effective at keeping what you don’t want out, and what you do want in. That's how ineffective your chimney can be without a proper and functioning liner.
And your chimney liner isn’t just a barrier - it’s protecting your home and its inhabitants from toxic gases and combustible byproducts.
There are a number of reasons why your chimney may need relining. Some historic homes have chimneys that were built without a liner -- a dangerous circumstance that should be corrected as soon as possible. Clay tile liners, while cost-efficient and common in older homes and chimneys, are prone to cracks and splitting, which could lead to the need for a new lining. Adding a new appliance may also bring a need for a resized flue to reach maximum efficiency, and a new lining can provide that.
A CSIA-certified A-1 Chimney Specialist technician can help you figure out whether chimney relining is right for your home, and if so, what material and approach is the best option for your needs and circumstances.
Quality chimney liners are generally made of clay tile, stainless steel or cast-in-place masonry. Each can be effective, and each has its strengths.
Clay tile tends to be the most cost-effective liner material, so you'll see it in many chimneys, including lots of older homes. When annually swept and inspected, clay tile can be a good and effective product. But clay tile does need to be properly maintained, or the tiles can split and crack, inhibiting the lining's ability to do its job. Newer gas appliances aren't as compatible with clay tile liners either. These aren't right for every chimney, and damaged clay tiles lead to one of the more common relining circumstances.
Pre-fabricated stainless steel liners are great options for relining chimneys with damaged clay liners or chimneys that need resizing due to the needs of new appliances. They are durable, safe and effective with many fuels, including wood, gas and oil, and they won't rust. When installed by a certified chimney company like A-1 Chimney Specialist, stainless steel liners also carry a lifetime warranty.
Cast-in-place masonry liners are another option for relining that can thoroughly seal existing cracks, gaps and other damage and strengthen your chimney. These are viewed by many as the most “permanent” relining option.
FireGuard is a relining and resurfacing system that can be used to repair and restore damaged or deteriorating clay tile liners. This can be a great option for liners that have a few cracks and gaps here and there or liners that need to be completely resurfaced.
