James Hardie siding asks very little of you. A gentle rinse once or twice a year keeps it looking sharp.
Simple Upkeep That Saves You Money
- Rinse, Don’t Repaint: A garden-hose rinse every 6 to 12 months clears pollen and grime, and ColorPlus siding never needs the repainting wood siding demands.
- Skip the Paint Bills: Repainting a house exterior can run up to $12,000, an expense ColorPlus Technology helps homeowners sidestep for years.
- No Rot, No Pests: Fiber cement won’t rot, warp, or feed carpenter ants and termites, so upkeep stays light through every season.
- Inspect the Caulk: Check caulk and trim joints once a year, and a quick James Hardie siding repair keeps small gaps from growing.
- Color That Lasts: The ColorPlus finish resists fading for 15 years, holding its tone against lakeside sun and reflected glare off the water.
- Gentle Cleaning Only: Use a soft brush and mild soap rather than a pressure washer, which protects the factory finish and keeps the warranty intact.
- Long Service Life: With this light care, James Hardie siding protects your home for decades, one reason its resale return reaches 144.9%.
