A Chimney Liner Can Save You Thousands

Autumn has arrived in full force this year. Colorful leaves decorate the ground, and the crisp winds have everyone digging up a cozy jacket. In addition, the chilly weather has homeowners thinking about heating their homes during the upcoming winter. For households that utilize fireplaces or stoves to provide heat, regular chimney maintenance is likely happening around this time of the year. Along with an annual chimney sweep, your fireplace and chimney should undergo a professional inspection. If your chimney has a damaged or missing liner, your mason should be concerned for the safety of your home – and with good reason.


An unlined chimney comes with a host of problems, and most of them are dangerous. One of the main purposes of a flue liner in your chimney is to protect the nearby structures from the extreme heat. A study done by the National Bureau of Standards determined that when a fire was burned in a fireplace with an unlined chimney, the adjacent woodwork took only 3 ½ hours to light on fire. This terrifying statistic means that using your fireplace for just one evening could result in an unintentional house fire. Instead of running this risk, you can have your mason install a high quality flue liner. At this relatively low cost, you can protect your home and your family for many winters to come.

On the other end of the spectrum, a liner inside the chimney also protects your home and chimney from water damage. With a masonry chimney, the materials like brick, mortar, and concrete are all porous and likely to absorb water. A good mason will have sealed the outside of your masonry chimney to prevent this absorption from the outside, but the inside usually goes unprotected. There are a number of ways to keep water out of your chimney, and one smart measure to take is having a flue liner. Without a flue liner, the brick and mortar readily absorb any water that happens to enter your chimney. While this seems innocuous enough, water in the masonry that undergoes a freeze and thaw cycle in freezing temperatures causes damage to the structure. This damage may turn into partial or total collapse. In addition to damaging the masonry, water in an unlined chimney is free to seep into the home. You can see this water damage very clearly in the plaster or dry wall of your ceilings and walls.

To save yourself thousands of dollars in potential repairs due to fire and water damage as a result of an unlined chimney, talk to your mason about taking the preventative measure of installing a chimney liner.
