Exterior painting projects start at a higher rate than interior work, and aluminum siding jobs in particular reflect both Colorado’s climate demands and the extensive prep required to get paint to stick properly to a metal substrate. Surface condition, square footage, accessibility, and how much oxidation and loose paint need to be cleared before priming all factor into final pricing.For the coating itself, we use UV-resistant, climate-rated paints from Sherwin-Williams and Benjamin Moore, both formulated specifically to prevent fading, cracking, and peeling on metal surfaces at high elevation. These aren’t general-purpose exterior paints; they’re selected because they bond to aluminum and hold up through Centennial’s intense sun and temperature swings.
