How to Repair Drywall Cracks in Older Virginia Homes

Drywall cracks in older Richmond homes are extremely common — and frustratingly persistent if not repaired correctly. The city's clay-heavy soil and seasonal temperature swings cause ongoing foundation movement that translates directly to wall cracking. Here is how to repair cracks that stay fixed.

Hairline cracks — very thin surface cracks with no depth — can be filled with lightweight spackle or a thin coat of joint compound. Sand smooth after drying, prime, and repaint. These cracks often reappear seasonally if the underlying movement continues, requiring annual touch-up.

Larger cracks with visible depth — 1/16 inch or wider — require embedding mesh tape before applying joint compound. Tape bridges the crack and prevents it from simply reopening as the compound dries and shrinks. Apply three progressively wider coats of compound, feathering each coat out 4–6 inches beyond the previous one.

Diagonal cracks running at 45-degree angles from door or window corners indicate stress concentration points caused by structural movement. These cracks are more serious and may indicate significant foundation settlement. If you see multiple diagonal cracks in a Richmond home, consult a structural engineer before making cosmetic repairs.

Stair-step cracks following mortar lines in brick exterior walls or CMU block are foundation-related and should be evaluated by a structural professional. Interior drywall cracks above these areas are a symptom — not the problem. PA Painting repairs drywall cracks throughout Richmond and can advise on whether the underlying cause requires attention before painting.
