We inspect all chimneys for safety, integrity, function, and leaks
The chimney are critical to safe operation of fireplaces , woodstoves, and other combustion appliances.  If poorly designed or maintained a fire or carbon monoxide poisoning could result. Some of the items we look for include:
  • flashing
  • exterior
  • mortar/bricks crowns
  • lining
  • checking for creosote
  • damper function

 See our sample chimney report here.

We recommend regular chimney maintenance. Have a fireplace professionally examined and clean the flue to keep this critical system in check. Chimney spark arrestors, also called rain covers, are recommended to prevent water penetration and prevent sparks from landing on the roof or other nearby combustible material.

Chimney cap (or crown)

The chimney cap is the top element of a masonry chimney. This mortar will not withstand years of weather abuse without cracking, chipping or deteriorating, these situations allow water to penetrate the chimney.  See an example of a failed crown here.


Flashing is the seal between the roofing material and the chimney. Flashing prevents rain water from running down the chimney into living spaces. The most effective flashing is made up of two elements, the flashing and the counter flashing. This two element flashing allows both the roof and the chimney to expand or contract at their own rates without breaking the waterproof seal in either area. See an example of an improperly flashed chimney here.
