Wood deck cost in Connecticut

Connecticut against its neighbors

Connecticut ranks 13 of 51 (the 50 states plus DC) for wood deck, where 1 is the most expensive. The costliest is Hawaii at $14,300 and the cheapest Oklahoma at $9,900, both for 300 sq ft at the midpoint. Connecticut sits at $11,600. The five states closest by workforce center are listed below.

Connecticut labor market for wood deck

Connecticut's labor line is priced from 2 trades, each compared with its US median wage. After weighting by each trade's share of the work, the state comes out at 1.09 times the national level.

Carpenters (47-2031), 80% of the weighting: a median of $30.80 an hour, 6% above the US median of $29.12. The middle half of them earn between $27.66 and $38.86 an hour. About 5,160 work in the state. That is 30.4 per 10,000 jobs, compared with 43.1 nationally, so expect fewer local crews to bid.

For construction laborers (47-2061, weighted 20%) the local median is $28.03 an hour, which is 24% above the national $22.66. The middle half of them earn between $22.92 and $34.98 an hour. BLS counts 7,360 of them working in the state, 43.4 for every 10,000 jobs (US: 70.5), so the local bench is thinner than average.

A crew paid at the 75th percentile for carpenters ($38.86 an hour) would add about $1,100 to the statewide midpoint; one at the 25th percentile ($27.66) would take off about $430. Use that as a rough guide to how far a bid can sit from our midpoint on wages alone.

BLS counts 1,696,170 jobs across Connecticut (May 2025), which is 1.1% of US employment.

Why two Connecticut quotes can differ

• Wood species

  Pressure-treated pine is the cheapest at $25-$50 per sq ft installed. Ipe runs $50-$70 and bamboo $27-$52 (HomeGuide).

• Height and stairs

  A second-story deck needs more structure. New stairs run $1,400-$2,600 installed.

• Railing

  A wood or vinyl railing adds $20-$60 per linear foot.

• Replacement versus new

  Deck replacement costs $30-$55 per sq ft because of demolition and haul-away.

• Permit

  Deck permits average $50-$150. Many cities skip the permit for small, low, freestanding decks.

Extras that change the Connecticut total

Add-ons start from national price ranges and are scaled by 1.03 for Connecticut, which is the average of the area's wage index (1.09) and goods price index (0.97). The estimator above can add them to your total.

Basic, standard or premium: Connecticut prices

Bands overlap on purpose, since a good standard job can cost as much as a light premium one. Below are the three bands for the default size, then a grid from 10x12 (120 sq ft) to 20x20 (400 sq ft).

Other Connecticut jobs that often go with wood deck

Each project weights the trades differently, so Connecticut's wage level does not push every price by the same amount. Compared with the US midpoint, paver patio is +10% and detached garage +4%.

When Connecticut weather lets you build

Weather decides when exterior installation can happen, and Connecticut is not uniform. The table uses NOAA's 1991-2020 climate normals from the weather station nearest each metro we cover, and counts the months that are neither cold nor hot enough to complicate the job.

Every Connecticut metro on the list has 9 comfortable months, though rainfall ranges from 42 inches a year in New Haven to 52 in Norwich.

We do not adjust prices by month, because we have no reliable published data on seasonal pricing. Timing is still worth raising when you collect bids.

Wood deck cost by metro in Connecticut

1 of the 5 metros sit above the statewide midpoint of $11,600, and the top-to-bottom gap is 3%. Each row prices the default size with that metro's own BLS wages and BEA price levels, so the gap between rows is real local variation rather than a flat markup.
