It depends on the size of the piece of siding, the type of siding, and the materials and labor involved. Generally speaking, you can expect to pay around $10-$15 per square foot for professional installation. So a piece measuring 4'x8' would cost around $320-$480 to replace.

It can cost anywhere from $3 to $15 per square foot to replace siding, depending on the type of materials used. So if you have a 10x10 piece of siding that needs to be replaced, it would cost between $30 and $150.
