How Much Does Siding Cost?
Siding is sold in "squares" of 100 square feet, and that unit alone is a common source of estimating error. Get the wall area and the trim right and the bid holds.
Cost by material
Vinyl is the value option at $4–$8/sq ft installed. Fiber cement (James Hardie) runs $6–$12 and is heavier to install. Wood and engineered wood sit at $8–$14. These are installed ranges — labor and the number of openings and corners move them.
What gets missed: squares, trim and waste
Wall area is measured in squares (100 sq ft), so mixing up squares and square feet mis-orders the whole job. Trim, soffit, fascia, corner posts and J-channel are easy to forget, and gables and openings drive waste. The siding calculator handles squares and waste for you.
From squares to a client quote
The Trowla siding calculator converts your wall dimensions into squares with waste, then lets you add trim, labor and your prices for a full total and a branded quote. No sign-up.
