Labor Cost to Install Siding
Split labor out from material so a quote stops being a single opaque number. Price labor by the square foot or by the square — whichever unit your crew works in.
Labor on 1,336 sq ft at $3.00/sq ft is $4,008.00, or $4,050.00 at 15 squares × $270.00/square. Labor is often 40–60% of a siding job; enter YOUR crew’s rate per square foot or per square to split labor from material and sanity-check a quote.

Material is easy to price; labor is where quotes diverge. Splitting the two is the single most useful thing you can do to read a siding bid, because it tells you whether you are paying for the product or for the crew’s time. Labor on a siding job is commonly 40–60% of the total, so a small error in the labor rate moves the whole number.
Crews price labor two ways: by the square foot, or by the “square” (100 sq ft) the way roofers and siders quote. This tool computes both from the same job so you can match whichever unit your contractor uses. The two should land close when the rates are consistent — if they diverge, one of the rates is off.
Formula
labor (by area) = net_area_sqft × $/sqft(labor)
labor (by square) = squares × $/square(labor)Because 1 square = 100 sq ft, a rate of $3.00/sq ft is the same as $300/square in principle; the two lines let you enter whatever your crew actually quoted without converting by hand.
Worked example
1,336 sq ft at $3.00/sq ft of labor:
labor = 1,336 × $3.00 = $4,008.00Or 15 squares at $270/square:
labor = 15 × $270 = $4,050.00The two agree to within about 1% — the small gap is the rounding up to whole squares. Either way, labor is roughly $4,000 on this house.
What moves the labor number
- Material weight and detail. Fiber cement is heavier and slower to hang than vinyl; shakes and board & batten have more pieces and trim. Heavier, fussier siding means a higher labor rate.
- Height and access. Two- and three-story walls, steep grades and tight lots add scaffolding and time. The whole-house labor estimator applies story and access multipliers for this.
- Tear-off is separate labor. Stripping old siding is its own line — do not fold it into the install rate.
- By the foot or by the square, be consistent. Convert once (100 sq ft = 1 square) and compare on one unit.
