he windows and doors are important functional components of a house or building. The windows and doors are important functional components of a house or building.  Most windows and doors are functional in that they can be opened and closed, although sometimes this requires considerable effort.

In some home inspections, building, condo, and co-op, especially older buildings, poor operation of windows and doors is due to normal settlement or normal wear and tear.  Sometimes, improper window or doors operation is due to structural defects in the building.

The Licensed Engineer analyzes the window and door operation to determine if there are structural defects.  For any problems found, the expense analysis in the inspection report helps you plan for future expenses.


Window replacement is an expense many buyers choose to undertake.Window replacement is an expense many buyers choose to undertake. The Licensed Engineer Inspector's evaluation of windows determines whether they function properly.  This includes checking for evidence of excessive wind or water leakage, damage, etc.  Even if the Engineer finds that the windows function, you may choose to replace them for personal reasons.

Windows are also checked for other concerns such as the need for caulking, draftiness, ease of operation, and leakage.  Many older windows are drafty, leak when it rains, and are difficult to operate.  Even newer windows may have problems.

Old windows are not as energy efficient as modern windows.  Buildings constructed during the 1960s may have leaky aluminum windows, while older houses have leaky double-hung wooded windows.  Buildings constructed before World War II may have leaky metal casement windows.

Even with storm windows in place, the old windows are not as energy-efficient as modern windows.  Today, windows are typically double-glazed to help reduce heating and cooling costs.  New windows are better insulated and require less maintenance than older windows.


Just like with the operation of the windows, door operation can be a clue to structural problems in a building.Just like with the operation of the windows, door operation can be a clue to structural problems in a building.  A door that binds may just be swollen due to moisture, or the binding  may indicate an underlying structural defect.  A doorframe that is not level may be the result of normal settlement or may indicate a structural defect.  A gap around a door may be present due to an underlying structural defects.

Older doors are not as energy efficient as modern doors.  Even with storm doors in place, the old doors are not as energy-efficient as modern doors.  Often, old doors have significant air leakage.

Today, doors typically contain insulation to help reduce heating and cooling costs.  Doors also require less maintenance than older doors.

Trust a Licensed Engineer to assess the windows and doors.
