Why Conway differs from the national price
Conway is in Carroll County, which the Bureau of Labor Statistics counts in the Northern New Hampshire nonmetropolitan area nonmetropolitan area. The median wage there for carpenters is $29.48 an hour against $29.12 nationally, so the labor part of a national price is scaled by 1.012 (+1.2%).
On this job the labor portion is $3,500 to $7,050 at national rates and $3,550 to $7,150 at Conway rates, so the midpoint rises $70 above the national figure. Against the New Hampshire statewide wage it is $10 higher. 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 Conway 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 $8,050 or above $16,100 is not wrong in itself, but it is worth asking what it includes or leaves out.
