Vinyl siding, aluminum, and stucco are the cheapest siding options:
Vinyl siding costs $3 to $11 per square foot installed, and the cost to replace vinyl siding on a 2,000-square-foot home is $4,300 to $15,800.
Stucco costs $3 to $9 per square foot installed or $6,400 to $10,700 total for a 2,000-square-foot home.
Aluminum siding costs $5 to $9 per square foot installed or $4,000 to $16,000 total for an average 2,000-square-foot home. Some new aluminum siding can be installed on top of your existing siding, allowing you to save on the cost of old siding removal. Check with a professional siding contractor for details.
