Coastal Climate Considerations

This includes moisture-resistant formulations that won't deteriorate in our subtropical climate. Vinyl may fade and become brittle, but fiber cement maintains its integrity for decades.
Hardie® Siding FAQs
How many HardiePlank planks do I need per 100 square feet?
For standard HardiePlank® lap siding with 7.5" exposure, you need approximately 13-15 planks per 100 square feet (1 square). Each 12-foot plank covers about 7.5 square feet. Our calculator automatically factors in 10% waste for cutting.
Is Hardie siding worth the extra cost vs vinyl?
Yes, for most homeowners. While Hardie costs 2-3x more than vinyl ($7-12/sq ft installed vs $4-7), it offers superior durability (50+ years vs 20-30), fire resistance, better resale value, and authentic wood appearance. In coastal areas, it resists salt air damage better than vinyl.
What is the difference between primed and ColorPlus Hardie?
Primed Hardie comes with a primer coating and requires on-site painting ($1-3/sq ft additional). ColorPlus® is factory-finished with baked-on paint that resists fading for 15 years. ColorPlus costs $4-5 more per plank but eliminates painting labor and provides superior finish quality.
How long does Hardie siding installation take?
A typical 2,000 sq ft home takes 5-10 days for experienced crews. HardiePlank® is heavier than vinyl (about 2.3 lbs/sq ft) and requires specific fastening patterns, so installation takes longer but ensures decades of performance.
Does Hardie siding need maintenance?
Minimal maintenance. ColorPlus® products need occasional cleaning with mild soap and water. Primed and painted Hardie may need repainting every 15-20 years. Unlike wood, it never needs scraping, doesn't rot, and resists insect damage. Caulk joints should be inspected annually.
Can Hardie siding be installed over existing siding?
While possible in some cases, James Hardie recommends removing old siding for best results. This allows inspection for hidden damage, proper water barrier installation, and ensures a flat surface for fiber cement. Removing old siding adds $1-2/sq ft but is worth it for long-term performance.
