Notes

Where the number comes from. The national price for a siding replacement is $800 per square — installed siding pricing published for 2026, $4–$16 per ft² depending on material. Labor is about 55% of that. Carpenters in Missouri average $65,000 a year against a U.S. mean of $65,630 — a factor of 0.99 — so the labor half is scaled by that and the material half is not.
What is in the price: tear-off of one layer, house wrap, the siding, J-channel and corner posts, fasteners, disposal and labor.
What is not: sheathing replacement found once the old siding is off, insulation added behind the new siding, window and door trim replacement, and permits. These are the lines that turn a $17,507 quote into a $21,884 invoice, so ask about each one before signing.
Why state matters more than people expect. Materials ship at national prices; crews do not move. Missouri sits below the national mean by 1%, which lands on 55% of the job and moves the total by $93.
Use this as a bid check, not a quote. It prices an average job in an average condition. Difficult access, the state of what is being replaced, the season, and a crew booked out three months all move the real number, and none of them are in a per-unit average.
