Frequently asked questions
How is siding measured?
Siding is sold by the square (100 sq ft). Divide your net wall area by 100 and add waste. This calculator does it and prices it.
How much does siding installation cost?
Installation is often quoted per square; set your crew rate and time per square in the estimate to match your market.
