How Storm Damage Affects Windows and Doors
Windows and doors are among the most vulnerable points of a home during severe storms. In the DMV region, airborne debris driven by thunderstorm winds regularly shatters glass, cracks frames, and compromises weatherseals. Even storms that don’t break glass can force water through aging seals and gaps in flashing, causing hidden water damage inside wall cavities.
DC’s historic row houses and Maryland’s colonial-style homes are particularly vulnerable because many retain original or early-replacement wood-frame windows with single-pane glass. These windows offer minimal resistance to wind-driven debris and provide poor weather sealing during heavy rain events. Northern Virginia’s newer construction fares better, but even modern vinyl and aluminum-clad windows can fail when impacted by large hail or flying branches.
Large hail — anything over 1.5 inches in diameter, which occurs several times per year in the DMV’s storm corridor — can crack double-pane insulated glass units, destroying the thermal seal and causing fogging between panes. This damage may not be immediately obvious but reduces the window’s energy efficiency and should be documented on storm damage claims.
What to Expect
Emergency and Permanent Repair
After a storm breaks windows or damages doors, the immediate priority is board-up to secure the opening against further weather and intrusion. Permanent repair follows once the scope is assessed and materials sourced.
Insurance and Claims
Window and door damage from storms is covered under dwelling coverage for covered perils. Claims should document each damaged unit individually with photos showing the damage cause.
