Why Fitzwilliam differs from the national price
Fitzwilliam is in Cheshire County, which the Bureau of Labor Statistics counts in the Southwestern New Hampshire nonmetropolitan area nonmetropolitan area. The median wage there for carpenters is $28.82 an hour against $29.12 nationally, so the labor part of a national price is scaled by 0.990 (−1.0%).
On this job the labor portion is $3,500 to $7,050 at national rates and $3,500 to $6,950 at Fitzwilliam rates, so the midpoint falls $50 below the national figure. Against the New Hampshire statewide wage it is $110 lower. Materials are priced at the national figure: shingle, lumber and equipment prices are set by distributors, not by a town.
A second published benchmark points the same way for the region: Remodeling's 2025 Cost vs Value report prices its “Deck Addition, Wood” job at $18,250 nationally and $20,600 in New England, and its “Deck Addition, Composite” job at $25,100 nationally and $25,800 in New England. Those are fixed specification jobs, not per-square-foot prices, so they are shown for comparison only.

Before asking for quotes
- The Fitzwilliam building department can say for free whether this job needs a permit and what it will cost; the schedule linked above is its own published document.
- Written quotes that list the same scope (area, material line, removal, disposal, permit) can be compared line by line; the quote comparison guide walks through it with these numbers.
- A quote far below $7,950 or above $15,950 is not wrong in itself, but it is worth asking what it includes or leaves out.
