The price of exterior lap-siding installation can range between $3 and $7 per square foot of coverage. The cost of the siding depends heavily on the materials used to create the siding panels.
There are several common lap-siding materials, including wood, aluminum, vinyl or fiber cement. Vinyl siding is the least expensive, with costs ranging between $3 and $4 per square foot. On the high end, fiber-cement and cedar-wood siding can cost anywhere from $4 to $7 per square foot. Other factors that affect cost include the quality of the material itself along with the finishing applied to the siding.
