Window Inspection Checklist Before Buying a Potomac Home

Start With The Windows You Can See From The Street

The goal is not to judge cosmetics alone. It is to spot signs that the windows have been repaired, neglected, or replaced in a way that may matter later.

Walk the perimeter and compare each elevation. In Potomac, it is common to see a mix of original windows, partial replacements, and newer units added one section at a time.

If the trim is soft, swollen, or peeling in a repeated pattern, moisture may have been getting in for a while.

When you are ready to move from inspection to action, a few practical questions help you stay grounded:

Are the issues isolated to a few windows, or are they spread throughout the house? Is the problem in the glass, the sash, the frame, or the surrounding trim? Will the job require permits, HOA review, or historic approval? Do the windows affect comfort, safety, or energy use enough to justify immediate replacement? Can the seller document prior work, warranties, or licensed installation?
