Wilmington Chimney LinersChimney liners are an important part of any well-functioning chimney, as they are responsible for properly venting toxic gases and smoke. Without a liner, homes are susceptible to fires because the speed at which heat is allowed to move through the chimney heightens the ability of a fire to start. In addition, chimney liners help to prevent corrosive gases and particles from a burning fireplace to permeate the walls of the chimney, which can lessen the lifespan of the chimney by destroying the mortar joints that hold it together. Finally, a liner can ensure that the drafts needed to supply combustion air to the appliance are optimized and properly transferred. This can help prevent buildups of dangerous byproducts of your chimney.
Chimney liners can be made out of a variety of materials, including clay, aluminum, stainless steel, and cast masonry. However, at the end of the day, regardless of the material, all liners have the same goal: provide a non-combustible lining to safely expunge dangerous byproducts of your chimney fire. Any flaws, damage, or deterioration in your chimney lining (including cracks, breeches, and general wear and tear) can cause problems. If your chimney liner is damaged, gases or combustible materials may be able to escape into attics, walls, or ceilings adjacent to your chimney. This can starts fires and/or cause damage to affected portions of your home, which, in addition to being dangerous, can lead to repairs and their associated costs. As part of a chimney inspection or cleaning, our technicians will look at the state of your liner and recommend any necessary repairs or modifications. If your fireplace smells bad, it is an indication that creosote and/or soot are building up on your chimney liner and will need to be cleared away. Sulfur, when mixed with moisture, creates a reaction that is able to eat through metal liners. Clay liners, meanwhile, are susceptible to cracking and deterioration, which can allow water or other liquids to seep through and cause water damage, an expensive problem to fix. If you see pieces of your clay liner on the floor or your firebox, you should strongly consider having your chimney and chimney liner inspected for any problems. In addition, if you change your heating system, you should ensure that the chimney liner you have is compatible with the requirements of the new system. Faulty chimney liners are responsible for causing more chimney fires than any other issue. Many older homes do not even have chimney liners despite the risks associated with operating a chimney without one. The National Fire Protection Association now requires all masonry chimneys to have a liner. Make sure your chimney is as well-equipped as it can be to handle the potential issues it may face.
