Every chimney has the same two jobs, venting smoke and gases outside and keeping the heat of the fire away from the house itself. Creosote buildup, a cracked flue liner, a blocked flue or water damage can quietly stop it from doing either one. A yearly visit from a Northbrook chimney sweep, before the first fire, catches most problems while they are still small.
In Northbrook, plenty of chimneys are original to the house, with clay flue tiles and mortar joints that have seen many winters, and newer homes are more likely to have prefabricated fireplaces with metal flues and chase covers on top. Each type wears out in its own way: brick chimneys crack, spall and leak, and prefab units rust, warp and lose their caps. A chimney sweep who works in Northbrook regularly sees both and knows what to look for.
Chimney work around Northbrook runs from routine cleaning to real repairs, from a smoky fire or a bad smell to a leak, a cracked crown or animals in the flue. Whether you need chimney cleaning in Northbrook or a repair after a storm, you do not need to know the cause. Tell the sweep what is going on and when it started.
