Best value: Vinyl at $1,440.00Vinyl siding is the most affordable but fiber cement (HardiePlank) offers superior durability, fire resistance, and curb appeal. Engineered wood provides a natural look at a mid-range price. Wood lap is the premium choice with traditional aesthetics but requires more maintenance. All prices include starter strip, J-channel, and corner accessories.
Vinyl siding longevityVinyl is the most budget-friendly option and typically lasts 20-40 years with minimal maintenance. Consider upgrading to insulated vinyl panels for better energy efficiency and impact resistance.
This is a material estimate for standard rectangular walls. Complex facades with gables, dormers, or mixed materials will require additional siding and trim. Always verify measurements on-site and consult your supplier for exact coverage per square.
