Where the Trenton price comes from
The wage side of the estimate leans on brickmasons and blockmasons, who do 50% of the hours on a typical job. Their local median is $37.03 an hour. Add the other trades involved and the blended wage index for Trenton is 1.31 (US = 1.00), which puts labor at 53% of the total. BLS does not publish this trade for the metro, so we used the New Jersey statewide median.
On the materials line, the BEA goods price index for the Trenton metro is 99.8 (US = 100). The midpoint materials bill for 200 sq ft of wall face comes to $5,300, compared with $5,300 at national prices. Permit and inspection fees are scaled by the broader index (103.2) 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 Trenton. The wage table below marks each row.

Trenton labor market for retaining wall
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 Trenton is 1.31 times the national level.
Brickmasons and blockmasons (47-2021) carry 50% of the labor weighting. BLS does not publish this trade for the Trenton metro, so we used the New Jersey statewide median: $37.03 an hour against $29.87 for the US. The middle half of them earn between $29.59 and $49.85 an hour.
Construction laborers (47-2061), 30% of the weighting: a median of $34.58 an hour, 53% above the US median of $22.66. The middle half of them earn between $23.43 and $51.14 an hour. About 960 work in the metro. That is 40.0 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 $33.56 an hour, which is 17% above the national $28.78. The middle half of them earn between $29.88 and $57.38 an hour. BLS counts 270 of them working in the area, 11.2 for every 10,000 jobs (US: 30.7), so the local bench is thinner than average.
Quotes come from real crews, not medians. If the brickmasons and blockmasons on your job are paid at the 75th percentile ($49.85 an hour) instead of the median, the labor line grows by about $1,000. At the 25th percentile ($29.59) it shrinks by about $590. The total moves by 8.6% or 5.0%, so wages alone rarely explain a quote that is far outside our range.
For context on the local economy, BLS counts 240,190 jobs in the Trenton-Princeton area. That makes it the 105th largest of the 300 metros we cover, with 0.15% of US employment.
| Trade | Weight | 25th pct | Median | 75th pct | US median | Ratio | Level used |
|---|---|---|---|---|---|---|---|
| Brickmasons and blockmasons (47-2021) | 50% | $29.59 | $37.03 | $49.85 | $29.87 | 1.24 | state |

Climate in Trenton: timing your retaining wall job
We use NOAA's 1991-2020 climate normals for Trenton Mercer Co Ap (5 miles from the city center). These are 30-year monthly averages, not forecasts.
March through November is the stretch where digging, grading and setting material in the ground runs into the fewest weather problems in Trenton (9 of 12 months). January, February and December have an average overnight low at or below freezing (32°F).
In January, February 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 97 days a year with a low at or below 32°F at this station.
Trenton gets about 46 inches of precipitation in a normal year, including roughly 27 inches of snow. The wettest months are June, July and August (4.4 inches in July). Inside the workable window, April and November are the driest, at 3.6 and 3.2 inches. The station averages about 22 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.
