How we build these numbers

We start from a US national baseline of $260 per square of siding material and multiply it by each state's relative construction cost index, where 1.00 is the national average. Those indices are directional — they capture broad differences in trade wages, material freight, and permitting overhead, not street-level pricing.

The ±12% band on every figure is deliberate. It reflects the range we would expect between a competitive bid and a premium one for the same scope in the same market. If a quote lands far outside that band in either direction, the scope is probably different from what you think it is — that is worth a conversation before it is worth a signature.

Siding cost by state: FAQ

How much does new siding cost on average in the US?

The national baseline we use is $260 per square of siding material. Applied to a typical average home project of 20 squares, that works out to roughly $4,576–$5,824 in materials at the unit shown. Labor, delivery, tax, and site prep sit on top unless the unit label says "installed."

Which states are most and least expensive for new siding?

The five priciest markets in our index are Hawaii, California, Alaska, New York, District of Columbia — Hawaii runs about $351 per square of siding material. The five cheapest are Mississippi, Arkansas, Oklahoma, Alabama, South Carolina, with Mississippi near $218. Top to bottom that is a spread of roughly 61%, which is why a national average alone is a poor budgeting tool.

Why does the same project cost so much more in some states?

Four things move the number: prevailing wage rates for the trades, freight distance from the nearest supplier or plant, permitting and inspection overhead, and local demand. Labor is usually the biggest lever — in high-wage metros it can be well over half the installed price. Freight matters most for heavy, low-value materials like concrete, gravel, and block, where hauling costs rival the material itself.

Are these numbers quotes?

No. They are directional planning figures built from a national baseline and a relative state cost index, and they are deliberately shown as ranges. Use them to sanity-check a bid or set a budget, not to negotiate a contract. Two contractors in the same ZIP code can legitimately differ by 20–30% based on crew size, backlog, and scope assumptions.

How do I get a number for my specific project?

Run the Siding Calculator with your own dimensions and your local unit price. The calculator does the quantity math exactly; this page just tells you what unit price is realistic where you live. Together they give you a defensible budget before you call anyone.
