How Often Should You Repaint Interior Walls?

By room

• High-traffic areas (hallways, kids' rooms, kitchens): every 3–5 years
• Living rooms and bedrooms: every 5–7 years
• Bathrooms: every 3–4 years (humidity accelerates wear and can promote mildew in paint film)
• Ceilings: every 10 years or so, unless there's visible staining or damage

Signs it's due regardless of the calendar

• Visible scuffs, marks, or stains that don't clean off
• Fading, especially on walls that get direct sunlight
• Hairline cracking or a chalky texture when you touch the surface
• Lingering odors that a fresh coat would help seal in and cover

Paint quality changes the math

Higher-quality paint (particularly higher-sheen finishes in high-traffic rooms) genuinely lasts longer and cleans better than economy-grade paint. If you're repainting more often than the ranges above, the paint quality or prep work (priming over stains, proper cleaning before painting) is worth reconsidering, not just the color.

Why this is more than cosmetic

Beyond appearance, paint is a protective layer — especially in bathrooms and kitchens, where it helps resist moisture and mildew. Letting it seriously degrade in those rooms can allow moisture to reach the drywall underneath.
