Why Portland prices look the way they do

Labor is 43% of the midpoint bill here, against 46% nationally. The mix of trades behind this job is brickmasons and blockmasons (50%), construction laborers (30%), operating engineers and other construction equipment operators (20%). We weight each trade's local median wage by that share and compare it with the national median. In Portland the blended ratio comes out at 0.85. BLS does not publish this trade for the metro, so we used the Maine statewide median.

On the materials line, the BEA goods price index for the Portland metro is 97.2 (US = 100). The midpoint materials bill for 200 sq ft of wall face comes to $5,150, compared with $5,300 at national prices. Permit and inspection fees are scaled by the broader index (101.9) and land at $50 to $460.

Data note: 50% of the labor weighting for this project uses a statewide median because BLS has no published metro figure for that trade in Portland. The wage table below marks each row.

What nearby projects cost in Portland

When to schedule retaining wall in Portland

We use NOAA's 1991-2020 climate normals for Portland Intl Jetport (5 miles from the city center). These are 30-year monthly averages, not forecasts.

April through October is the stretch where digging, grading and setting material in the ground runs into the fewest weather problems in Portland (7 of 12 months). January, February, March, November and December have an average overnight low at or below freezing (32°F).

In January, February, March, November and December the average low is at or below freezing, which means frozen ground and slower digging, compaction and sod or stone placement. NOAA counts about 144 days a year with a low at or below 32°F at this station.

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.

Does the season change the price? Probably, but we do not have a sourced seasonal price curve, so the estimator shows a year-round figure and does not adjust by month. When you collect quotes, ask whether scheduling in a slower month gets a better rate.

Specs and site conditions that change a Portland bid

  • Rebuilding

    Replacing an old wall adds $15-$30 per linear foot for demolition plus disposal.

  • Permit

    Permits cost $50-$450 depending on location and wall size.

  • Height

    Walls over 4 feet need engineering, deeper excavation and more skilled labor; many cities require permits over 3-4 feet (HomeGuide).

Local wages behind the labor line

Wages are the part of this estimate that changes most from town to town. 3 trades carry the job here, and each is compared with its US median. The weighted result for Portland is 0.85 times the national level.

Brickmasons and blockmasons (47-2021) carry 50% of the labor weighting. BLS does not publish this trade for the Portland metro, so we used the Maine statewide median: $20.54 an hour against $29.87 for the US. The middle half of them earn between $19.31 and $28.53 an hour.

Construction laborers (47-2061), 30% of the weighting: a median of $23.31 an hour, in line with the US median of $22.66. The middle half of them earn between $21.50 and $27.46 an hour. About 1,470 work in the metro. That is 51.0 per 10,000 jobs, compared with 70.5 nationally, so expect fewer local crews to bid.

For operating engineers and other construction equipment operators (47-2073, weighted 20%) the local median is $28.62 an hour, which is in line with the national $28.78. The middle half of them earn between $25.00 and $30.84 an hour. BLS counts 880 of them working in the area, 30.5 for every 10,000 jobs (US: 30.7), so the local bench is about average.

Quotes come from real crews, not medians. If the brickmasons and blockmasons on your job are paid at the 75th percentile ($28.53 an hour) instead of the median, the labor line grows by about $630. At the 25th percentile ($19.31) it shrinks by about $95. The total moves by 6.7% or 1.0%, so wages alone rarely explain a quote that is far outside our range.

For context on the local economy, BLS counts 288,480 jobs in the Portland-South Portland area. That makes it the 89th largest of the 300 metros we cover, with 0.19% of US employment.

Where these numbers come from

Base prices are national ranges from the sources below. We scale labor by local BLS wages, materials by BEA goods prices and permits by the BEA all-items price level. Full method on the methodology page.

Note on derived figures: Materials = 40% of the low installed price and 60% of the high one, since HomeGuide says labor is 40-60% of the total project cost.
