What you need to know about Chimney Sweeping
How often should a chimney be inspected?
Chimneys should be inspected every year. New wood-burning installations such as fireplaces or wood-burning stoves should be checked midway through the first heating season to confirm everything is working properly.
How often should a chimney be cleaned?
Cleaning should be done as necessary — normally when there’s a minimum 1/8-inch of deposit in the chimney. An annual inspection will determine if any sweeping or repairs are needed.
In some cases, it’s necessary to sweep more than once a year, especially if the operator, the fuel or the venting system are not properly matched.
Why should you get your chimney inspected?
The combustion process deposits an acidic material that weakens masonry or metal chimneys, causing them to deteriorate prematurely.
Significant buildup of creosote, a flammable material resulting from incomplete combustion, may catch fire and spread to the attic and other areas of the home.
If a chimney is used infrequently, critters and birds can collect and nest there, blocking the chimney. Leaves, twigs, pine cones and branches can obstruct the chimney, too.
