Window Inspection Checklist Before Buying a Potomac Home

Read The Exterior Before You Open A Single Sash

Before you ever ask about age or warranties, the exterior window condition gives away clues about water intrusion, energy performance, and whether the home has been patched together over time.

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.

Pay attention to paint lines, trim condition, and caulk joints around the frame.

Fogging or moisture between panes Wood damage, bubbling paint, or distorted frame edges Sashes that no longer sit square in the frame Failing caulk, visible gaps, or sloppy weatherproofing Mixed window styles that do not match the rest of the home
