Chimney Lining – Seattle Chimney Liners
Prevent chimney damage by lining older or often used chimneys. Excel Chimney builds custom liners to fit your fireplace and protect your home.
A lined chimney is one that has a layer of protection (usually clay or metal) inside the single width of brick needed to create the chimney stack. For the last 50 years or more, Seattle chimneys have been constructed with clay flue liners. Prior to that, many chimneys were built with a single width of brick for each flue. Older chimneys with multiple fireplaces and/or furnace flues will have interior walls dividing the flues, but not a liner. Excel Chimney will protect your house with a replacement chimney liner.
Not just for wood burning fireplaces.
However, few homeowners who use their chimneys merely to vent gas or oil-fired furnaces and boilers are aware that maintenance and sound conditions apply to them, too. That’s a problem because the byproducts of burning gas and oil are just as insidious as those from solid fuels.
There are a variety of reasons to line a chimney flue, but it all boils down to safety! Chimneys—or more specifically, the flues within them—must be clean and sound to carry heat and gases safely up and away from the chimney top, but these combustion byproducts can also deteriorate a flue’s inner surface over time. The risk is crumbled or deteriorating bricks and masonry allowing embers or sparks to ignite the structure.
The Line on Seattle Chimney Liners
Among the best reasons for relining a masonry chimney is that it wasn’t built right in the first place—that is, without a flue liner, a material that provides a smooth, relatively seamless surface as well as insulation. Age and use can open cracks in tiles, and combustion gases combined with rain will erode parging and masonry joints between bricks or stones.
Seattle is hard on Chimney Flues – Liners can extend their lives
All masonry exposed to the weather slowly breaks down do to the effects of sun, wind, rain and cold. Chimneys that are not well capped or maintained can have this breakdown extend into the interior of the flue creating unsafe conditions. Additionally, the exhaust from furnaces and other appliances is very hard on the inside of chimney flues. The main reason for interior chimney breakdown is the acidic moisture that comes from condensed flue gases. Water vapor is present in the exhaust; it cools and condenses as it rises in the chimney forming vapor clouds that literally rain in your chimney. Countless drops of acidic moisture soak the flue, breaking it down.
Damaged chimney flues are unsafe in a couple of ways. Flue gases from appliances or wood burning can escape into the home potentially causing illness. Wood burning deposits creosote in the chimney. This creosote can catch fire. This chimney fire can, in some cases, result in a house fire.
