Concrete patio cost in Portland, ME

Extras that change the Portland total

Add-ons start from national price ranges and are scaled by 1.02 for Portland, which is the average of the area's wage index (1.06) and goods price index (0.97). The estimator above can add them to your total.

Who does the work: Portland trade wages

The labor line is built from BLS wage data, one trade at a time. This job draws on 4 trades. We compare each trade's local median with the US median, weight the ratios by how much of the job each trade does, and apply the blend to the national labor cost. For Portland the blend is 1.06.

Cement masons and concrete finishers (47-2051), 50% of the weighting: a median of $30.01 an hour, 9% above the US median of $27.41. The middle half of them earn between $24.70 and $31.25 an hour. About 330 work in the metro. That is 11.4 per 10,000 jobs, compared with 13.3 nationally, so the supply of crews looks typical.

For construction laborers (47-2061, weighted 30%) the local median is $23.31 an hour, which is in line with the national $22.66. The middle half of them earn between $21.50 and $27.46 an hour. BLS counts 1,470 of them working in the area, 51.0 for every 10,000 jobs (US: 70.5), so the local bench is thinner than average.

Carpenters (47-2031), 10% of the weighting: a median of $30.91 an hour, 6% above the US median of $29.12. The middle half of them earn between $28.45 and $35.95 an hour. About 2,230 work in the metro. That is 77.3 per 10,000 jobs, compared with 43.1 nationally, which suggests plenty of local crews to bid.

Operating engineers and other construction equipment operators (47-2073), 10% of the weighting: a median of $28.62 an hour, in line with the US median of $28.78. The middle half of them earn between $25.00 and $30.84 an hour. About 880 work in the metro. That is 30.5 per 10,000 jobs, compared with 30.7 nationally, so the supply of crews looks typical.

A quick sensitivity check: moving the lead trade (cement masons and concrete finishers) from the median to the 75th percentile wage adds about $30 to the midpoint estimate; the 25th percentile takes off about $130. That is a swing of roughly 4.9% to 1.1% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.

Portland-South Portland has 288,480 jobs in total (BLS, May 2025), ranking 89th by size among the 300 metros on this site.

Specs and site conditions that change a Portland bid

• Site prep

  Excavation, forms and a gravel base are the unglamorous part of the bill and vary most with soil and slope.

• Size

  Small patios carry fixed costs for forms and mobilization, so the per-square-foot price drops as the patio gets bigger.

• Permit

  Permits run $50-$400 where required. Many cities don't require one for a small at-grade patio.

The best months for concrete patio in Portland

Climate numbers on this page come from NOAA's 1991-2020 U.S. Climate Normals at the nearest suitable station, Portland Intl Jetport (5 miles from the city center). They are 30-year averages, so any one year can run hotter, colder or wetter.

For pouring concrete, the comfortable months in Portland are May through October: 6 of 12. Outside them, January, February, March, April, November and December have an average overnight low of 40°F or below.

The 40°F line is a deliberately cautious stand-in. The American Concrete Institute's cold-weather guide (ACI 306R-16) defines cold-weather concreting around an average daily air temperature below 40°F, which is colder than our test of an average overnight low at or below 40°F, so we flag a few extra shoulder months. In cold weather crews may need heated enclosures, insulating blankets or accelerated mixes, and those measures can raise a quote.

Portland gets about 48 inches of precipitation in a normal year, including roughly 69 inches of snow. The wettest months are April, October and December (5.3 inches in October). Inside the workable window, July and August are the driest, at 3.4 and 3.6 inches. The station averages about 5 days a year at 90°F or above.

We do not adjust the estimate by month, because we have no reliable published data on seasonal pricing. It is still worth asking contractors whether an off-peak start date changes their bid.
