Why Your Denver Home Has Drywall Cracks (and How to Fix Them Right)

Drywall cracks are one of the most common calls we get from Denver homeowners. The good news: most aren't structural. The bad news: if you patch them with spackle and paint, they'll be back in 6 months. Here's how to do it right.

Why Denver homes crack

• Expansive clay soil. The front range sits on bentonite clay that swells when wet and shrinks when dry, moving foundations seasonally.
• Extreme dry air. Indoor humidity often drops below 15% in winter, shrinking wood framing and joint compound.
• Settling. Newer construction (post-2015) is especially prone in the first 5 years.
• Truss uplift. Common in Colorado attics — ceilings pull up from interior walls in winter.

The permanent fix (for hairline cracks)

1. Open the crack slightly with a utility knife in a V-shape.
2. Embed paper or fiberglass mesh tape over the crack with setting-type joint compound (not pre-mixed).
3. Apply 2–3 wider coats, feathering each one out further than the last.
4. Sand smooth, prime, and paint.

The key step everyone skips is the tape. Spackle alone always fails on Denver homes because the wall keeps moving — tape is what bridges the movement.

When to worry (and call a structural engineer)

• Cracks wider than 1/4 inch.
• Stair-step cracks in basement walls or brick exteriors.
• Doors and windows that suddenly stick.
• Floors that have noticeably tilted.
