What is behind the Clarksville number
Labor is 63% of the midpoint bill here, against 67% nationally. The mix of trades behind this job is carpenters (50%), cement masons and concrete finishers (10%), electricians (10%), plumbers, pipefitters and steamfitters (10%), drywall and ceiling tile installers (10%), roofers (10%). We weight each trade's local median wage by that share and compare it with the national median. In Clarksville the blended ratio comes out at 0.82.
On the materials line, the BEA goods price index for the Clarksville metro is 96.2 (US = 100). The midpoint materials bill for 300 sq ft comes to $17,300, compared with $18,000 at national prices. Permit and inspection fees are scaled by the broader index (90.9) and land at $450 to $1,800.
Data note: 10% of the labor weighting for this project uses a statewide median because BLS has no published metro figure for that trade in Clarksville. The wage table below marks each row.
Clarksville labor market for home addition
Wages are the part of this estimate that changes most from town to town. 6 trades carry the job here, and each is compared with its US median. The weighted result for Clarksville is 0.82 times the national level.
For carpenters (47-2031, weighted 50%) the local median is $23.60 an hour, which is 19% below the national $29.12. The middle half of them earn between $21.48 and $28.68 an hour. BLS counts 290 of them working in the area, 28.1 for every 10,000 jobs (US: 43.1), so the local bench is thinner than average.
For cement masons and concrete finishers (47-2051, weighted 10%) the local median is $23.05 an hour, which is 16% below the national $27.41. The middle half of them earn between $19.92 and $23.05 an hour. BLS counts 130 of them working in the area, 12.6 for every 10,000 jobs (US: 13.3), so the local bench is about average.
Electricians (47-2111), 10% of the weighting: a median of $28.21 an hour, 7% below the US median of $30.38. The middle half of them earn between $22.27 and $37.37 an hour. About 500 work in the metro. That is 48.4 per 10,000 jobs, compared with 48.7 nationally, so the supply of crews looks typical.
For plumbers, pipefitters and steamfitters (47-2152, weighted 10%) the local median is $28.33 an hour, which is 8% below the national $30.67. The middle half of them earn between $21.59 and $37.55 an hour. BLS counts 280 of them working in the area, 27.1 for every 10,000 jobs (US: 30.0), so the local bench is about average.
Drywall and ceiling tile installers (47-2081), 10% of the weighting: a median of $18.98 an hour, 33% below the US median of $28.33. The middle half of them earn between $17.92 and $22.11 an hour. About 40 work in the metro. That is 3.9 per 10,000 jobs, compared with 5.3 nationally, so expect fewer local crews to bid.
Roofers (47-2181) carry 10% of the labor weighting. BLS does not publish this trade for the Clarksville metro, so we used the Tennessee statewide median: $21.97 an hour against $26.65 for the US. The middle half of them earn between $18.33 and $23.53 an hour.
Quotes come from real crews, not medians. If the carpenters on your job are paid at the 75th percentile ($28.68 an hour) instead of the median, the labor line grows by about $3,350. At the 25th percentile ($21.48) it shrinks by about $1,400. The total moves by 6.7% or 2.8%, so wages alone rarely explain a quote that is far outside our range.
For context on the local economy, BLS counts 103,220 jobs in the Clarksville area. That makes it the 200th largest of the 300 metros we cover, with 0.07% of US employment.

Climate in Clarksville: timing your home addition job
We use NOAA's 1991-2020 climate normals for Clarksville Wwtp (in the city). These are 30-year monthly averages, not forecasts.
March through June and September through November are the stretches where digging, grading and setting material in the ground runs into the fewest weather problems in Clarksville (7 of 12 months). January, February and December have an average overnight low at or below freezing (32°F); July and August have an average daytime high of 90°F or more.
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 79 days a year with a low at or below 32°F at this station.
Clarksville gets about 54 inches of precipitation in a normal year. The wettest months are April, May and December (5.6 inches in May). Inside the workable window, September and November are the driest, at 3.4 and 4.1 inches. The station averages about 57 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.
