Chimneys


Did you know chimney rebuilding is a common repair for the homeowner. Most masonry chimneys do not have issues unless they are located above the roof line. Below the roof line the chimney is protected by the roof itself. Above the roof line, the chimney is susceptible to many environmental exposures. Rain, snow, wind and sudden changes of temperatures to the top of the chimney flue liner are factors.


The hottest part of a fire is the top of the flame which is at the flue liner above the roof line. When you combine a cold evening with the starting of a fireplace, the extreme change in temperature affects the top section of the flue liner, causing it to break away from the crown.  This leads to water damage that will continue to destroy the chimney from both the inside and outside. We rebuild or repair your chimney to fire code standards including the installation of a fire rated caulking.
