Inspecting Windows and Doors Heritage Building (Canada)

The openings into a building — the doors and windows — are often subject to harder use than other parts of a building, so they require more frequent and careful examination. Doors and windows that do not close correctly can cause air leaks, leading to inefficiency in heating and cooling - this can be mitigated with the installation of a weather strip, or caulking. Windows in historic buildings typically have wooden window frames and window sills, which may crack, warp, or expand/contract creating gaps. Similarly, most doors on historic buildings are of wooden construction, and are subject to shrinkage, warping, swelling, cracking and decay. Due to the likelihood of wooden construction, regular inspection is important. A qualified inspector is able to identify gaps, air leaks, water intrusion, and other damage, and can make suggestions for ways to improve energy efficiency, including repairs or replacement windows and doors.
