How Long Does Exterior Paint Last in San Diego?

Sun Exposure

South and west-facing walls receive the most intense UV exposure and typically fade 20-30% faster than north and east-facing walls. In inland San Diego areas like Alpine and Lakeside, where afternoon temperatures soar, this effect is even more pronounced.

Paint Quality

Premium paints from Sherwin-Williams, Benjamin Moore, and Dunn-Edwards contain more pigment, better binders, and UV-blocking additives. While they cost more upfront, they last 2-4 years longer than economy paints. The cost difference is typically recovered through extended paint life.

Surface Preparation

Preparation is arguably more important than the paint itself. Proper power washing, crack repair, priming, and caulking ensure paint adheres correctly and lasts its full potential. Skipping prep is the #1 reason for premature paint failure.

Color Choice

Darker colors absorb more heat and UV rays, causing them to fade faster and putting more stress on the paint film. Lighter colors, especially on sun-exposed walls, maintain their appearance longer. If you love dark colors, consider them for shaded areas or north-facing walls.

Climate Factors

While San Diego's mild climate is generally favorable for paint, inland areas face unique challenges: Santa Ana winds that carry abrasive dust, wide temperature swings between day and night, and lower humidity that can cause paint to dry too quickly if not applied properly.
