Why Hartford differs from the national price
Hartford is in Hartford County, which the Bureau of Labor Statistics counts in the Hartford-West Hartford-East Hartford, CT metropolitan area. The median wage there for carpenters is $31.14 an hour against $29.12 nationally, so the labor part of a national price is scaled by 1.069 (+6.9%).
On this job the labor portion is $3,500 to $7,050 at national rates and $3,750 to $7,550 at Hartford rates, so the midpoint rises $370 above the national figure. Against the Connecticut statewide wage it is $60 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.
Hartford at a glance
The Census Bureau estimates 121,981 people lived in Hartford on July 1, 2025, up 0.8% from the 121,054 counted in the 2020 census. On 17.38 square miles of land that is 6,966 people per square mile in 2020, among the densest places on this site (2 of 24); dense Connecticut city blocks mean small lots, shared walls and street parking that crews price into access and staging.
25.7% of Hartford's occupied homes are lived in by their owners, fewer than the 66.5% across Connecticut, and the median owner-occupied home is valued at $228,600 (Connecticut: $366,900). The midpoint estimate for this deck works out to 5.4% of that median value.
Before asking for quotes
- The Hartford 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 $8,250 or above $16,500 is not wrong in itself, but it is worth asking what it includes or leaves out.
