Exterior paint fading or chalking — Los Angeles, California

Exterior paint that has noticeably faded, chalked, or lost its original vibrancy is more than a cosmetic issue — it signals that the protective film on your siding, trim, or stucco is breaking down and leaving the substrate exposed to moisture, UV radiation, and temperature swings. Chalking is the white, powdery residue you can rub off with a finger, caused by the paint binder degrading under sunlight. South- and west-facing walls fade fastest because they receive the most direct sun. Low-quality paint, insufficient surface preparation, or applying paint too thin during the original job accelerates the problem. Left unaddressed, the exposed wood, fiber cement, or stucco absorbs water, leading to rot, efflorescence, or cracking that costs significantly more to repair. A professional exterior repaint typically runs $3,000–$8,000 for an average-sized home depending on siding material, number of stories, and prep work required. Proper prep — power washing, scraping loose paint, priming bare spots — accounts for most of the labor and determines how long the new coat lasts (7–15 years for quality acrylic latex).
