Sticking Doors and Windows — Is It a Foundation Problem in Chattanooga?

Sticking doors and windows are one of the most common early signs of foundation movement in Chattanooga homes — and one of the most commonly dismissed. Homeowners often attribute sticking to humidity swelling the wood, and in some cases they're right. But in Hamilton County's clay soil, sticking doors and windows are frequently the first visible symptom of foundation settling.

Here's how to tell the difference: humidity-related sticking is typically seasonal (worse in summer, better in winter) and affects multiple doors throughout the house. Foundation-related sticking tends to be localized (specific doors or windows, often in the same part of the house), worsens over months or years rather than improving seasonally, and is accompanied by other signs like diagonal cracks at door corners or slightly unlevel floors near the affected openings.

If you're seeing sticking on multiple interior doors on the same side of the house, combined with any cracking at opening corners, that's worth a professional evaluation. Our free inspection takes about an hour and includes floor level measurements across the affected area — measurements that often tell us more than the visible cracks do.
