Exterior Painting Cost in Louisiana (2026)

Repainting a 1,500 sq ft home in Louisiana typically runs $2,800–$7,800, with wood lap or shake siding the dominant residential substrate driving prep scope. Louisiana's combination of 80%+ year-round humidity, persistent Gulf salt-spray on every coastal exposure from Cameron to Plaquemines, and the longest residential mildew-growing season in the continental U.S. drives the shortest mainland exterior repaint cycle outside Florida and Hawaii — New Orleans, Baton Rouge, and Lafayette wood-lap exteriors typically require recoat at 5-7 years versus 10-12 years in moderate climates, with mildewcide-additive 100% acrylic primer-and-topcoat now the dominant southern-Louisiana residential coatings spec.

Louisiana climate & coatings drivers

  • IECC climate zone: 2A-3A
  • Dominant residential substrate: Wood lap or shake — dominant pre-1990 substrate, drives full prep + caulk + prime + 2-coat
  • Annual humidity tier: Very high — 75%+ year-round drives mildew bloom + biocide-additive coatings
  • UV exposure: High — long sun seasons drive south-facing fade in 5-7 years on standard topcoats
  • Salt-air corrosion zone: High-corrosion coastal — marine-grade alkyd primer + stainless fastener replacement on every coastal repaint
  • Freeze-thaw cycling: Low — occasional freeze events
  • VOC architectural coatings rule: Federal default — 250 g/L flat exterior topcoat limit (EPA 40 CFR Part 59)
