Common Window and Door Conditions Home Inspectors Evaluate During Residential & Commercial Property Inspections

Windows and exterior doors are essential components of a home's or commercial building's exterior envelope, providing natural light, ventilation, security, emergency egress, and protection from the elements. Properly installed and maintained windows, doors, flashing, weatherstripping, and trim help prevent water intrusion, air leakage, energy loss, and premature deterioration of surrounding building materials. During every home inspection, commercial building inspection, Property Condition Assessment (PCA), and pre-listing inspection, Structure Check carefully evaluates the visible condition of windows, doors, and their related components for deficiencies that may affect safety, operation, weather resistance, energy efficiency, or long-term performance.

This educational gallery showcases many of the common window and door conditions, installation defects, maintenance concerns, and safety hazards discovered during residential and commercial property inspections throughout Southern and Central New Hampshire and Maine. Every building is different, with varying window styles, door assemblies, construction methods, and exposure to weather. These examples provide homeowners, buyers, sellers, investors, and commercial property owners with valuable insight into the types of conditions professional inspectors commonly evaluate during a window and door inspection.
