In 2025-2026 US markets, a siding contractor charges $2 to $7 per square foot for labor, which works out to $200 to $700 per square. A square is 100 square feet of finished wall area. Most single-family homes on a simple one-story lot fall between $3 and $5 per square foot when the existing substrate is sound and the crew can work from ladders.

That number is labor only. It covers the crew: handling panels, cutting, nailing, flashing standard window and door openings, caulking joints, and cleaning up. It does not cover the siding material, removing old cladding, replacing rotted sheathing, scaffolding for tall or steep walls, or permit fees. If a bid includes material and labor together, expect the combined figure to run from $6 to $14 per square foot depending on the product.

Per square foot vs per square: how the quote is built

Siding contractors measure in squares, not square feet. A square is a 10-foot by 10-foot wall face: 100 square feet. When an estimator says a house has 18 squares of wall, that is 1,800 square feet of finished surface. Using squares keeps the math short on site and matches how siding is sold.

A written quote usually shows a per-square labor rate. If the labor line reads $450 per square, that is $4.50 per square foot. Do not work from a verbal per-square-foot number alone. Ask for the wall area in squares and the labor rate per square. That is the number you compare across bids.

What the per-square-foot rate actually covers

A standard labor rate assumes a straight wall with sound sheathing, existing house wrap or felt in usable condition, and normal 8-foot wall heights. The crew installs the siding, fasteners, basic corner boards, and standard drip cap over windows and doors unless the quote says otherwise. They caulk the final joints and remove job-site scrap.

The rate does not include removing existing siding, repairing rotted wood, replacing house wrap, reframing windows, permitting, or hauling a large dumpster. Those items should appear as separate line items. If they do not appear, the estimate is low by design, not by accident.

Labor rates by siding material

Material drives labor productivity more than any other variable. The table below shows labor-only ranges for a standard one-story, 1,800-square-foot home with square corners and normal access.

Siding material	Labor per sq ft	Labor per square	What the crew deals with
Vinyl lap siding	$1.75–$3.50	$175–$350	Light panels, fast to cut; speed depends on straight walls.
Insulated vinyl	$2.00–$4.00	$200–$400	Heavier backing slows handling and corner work.
Fiber cement plank	$3.00–$6.50	$300–$650	Heavy boards, silica dust, special blades, more layout.
Engineered wood	$2.50–$5.00	$250–$500	Cuts like wood, faster than fiber cement, needs touch-up.
Cedar or natural wood	$3.50–$7.00	$350–$700	Face-nailing, joint alignment, finishing decisions.
Aluminum or steel	$2.50–$5.50	$250–$550	Coil cutting, metal trim bending, oil-canning risk.

Production rates: how many square a crew installs per day

Production rate is why labor cost moves. A three-person vinyl crew on a square single-story home can hang 6 to 8 squares per day including basic trim. Fiber cement drops to 3 to 5 squares per day. Cedar and engineered wood usually sit between 4 and 6 squares. If the crew bills $1,800 per day, that labor rate shifts from roughly $225 per square on a fast vinyl day to $600 per square on a hard fiber cement job.

Those daily numbers assume flat, accessible walls and a truck that can park close. Every extra trip, ladder movement, and window cut pulls the daily square count down and pushes the per-square labor number up.

Site factors that change your labor number

A two-story wall adds ladder setup, moving material to height, and slower nailing. Many windows and corners mean more cuts, more flashing, and more caulk. A house with unusual shapes, gables, or deep roof overhangs takes longer to lay out than a simple rectangle.

Old siding changes the job even more. Tearing off cedar shakes, asphalt siding, or stucco is a separate labor task. The crew may also find rotted sheathing behind the old cladding. That repair time should be added as a line item, not hidden inside the per-square rate.

Scope changes that move the quote

When you compare bids, the differences are usually in the add-ons, not the base rate. These line items show up on most replacement jobs outside a clean new-construction install.

Line item	Typical labor add	Why it changes the number
Tear-off and dumpster	$1.00–$2.50 per sq ft	Removal can take as long as installation on older homes.
OSB or plywood repair	$1.50–$3.00 per sq ft	Rotted corners and window sills get cut out and replaced.
New house wrap or rigid foam	$0.25–$0.80 per sq ft	Requires overlapping, taping, and staging before siding.
Scaffold or lift for 3-story walls	$1.00–$3.00 per sq ft	Setup time and slower work at height.
Trim and corner boards	$2–$6 per linear ft	Each piece is measured, cut, caulked, and painted where exposed.
Permit and office fees	$150–$500 flat	Plan review, inspection scheduling, and admin time.

Reading a siding quote line by line

A serious quote separates the job into pieces you can check. When the quote only gives one lump sum, you cannot see which assumptions are missing. Ask for the wall area in squares, the labor rate per square, and a separate line for every removal, repair, or access item.

Line item	What it should say	Red flag
Wall area	“22 squares measured by wall face”	“Siding as needed” with no square count.
Siding material	Brand, profile, thickness, color	“Siding package” with no product name.
Labor	Rate per square, trim included or separate	“Labor included” with no quantity.
Tear-off	Per-square removal and disposal	Bundled into labor without a quantity.
Scaffold or lift	Flat fee or per-day rate	“Access as needed” with no price.
Flashings	Metal type and locations	“Standard flashing” with no specs.

Verdict: the number to hold contractors to

For a straight one-story replacement without tear-off, hold labor to roughly $300 to $450 per square for vinyl, which is $3.00 to $4.50 per square foot. For fiber cement, expect $400 to $600 per square. If the home is two stories, has old siding coming off, or needs sheathing repair, add those items separately instead of accepting one blended rate.

A realistic labor budget for an 1,800-square-foot home with one layer of vinyl over sound plywood is usually $5,400 to $8,100 before material and waste. That range assumes normal access, standard trim, and no hidden decking rot.

How we estimated these figures

The ranges in this guide come from standard job-cost methods: crew day rates, production rates per material, and estimated hours for tear-off, trim, and flashing. We assume a 3- or 4-person crew, a combined labor burden of $1,200 to $2,200 per day, and a 1,800-square-foot single-family home with average access.

Regional wage differences, local competition, and city permit requirements move these numbers. They are planning ranges, not a bid. A written quote for your address should always replace a general range.

What this guide does not cover

This guide does not price the siding material itself, insulation, gutters, soffits, interior repairs, mold remediation, or structural framing. It does not cover painting and staining of natural wood, manufacturer warranty requirements, engineered fastener schedules, or HOA design approvals. It also does not address commercial, multifamily, or historic restoration work, where access and code requirements are different.

FAQ

Does the per-square-foot labor rate include materials?

No. The rates in this article are labor only unless a contractor states “installed” or “with material.” Many homeowners compare a labor-only quote against a material-and-labor quote and misread the difference. Ask for material and labor as separate line items, then compare both.

Why does fiber cement cost more per square foot than vinyl?

Fiber cement is slower to install. Boards are heavier, produce silica dust, require special cutting tools, and need caulk and paint at exposed cuts. A crew that hangs 8 squares of vinyl in a day might hang 4 squares of fiber cement, so the labor cost per square nearly doubles.

How many squares should a siding crew install per day?

For vinyl on a single-story, accessible home, expect 6 to 8 squares. Fiber cement runs 3 to 5 squares. Engineered wood usually 4 to 6 squares, and cedar 3 to 5. These are full-day estimates for a 3-person crew. Tall walls, many windows, or tear-off cut daily production by a third or more.

Should I compare bids by price per square foot?

You can compare per-square-foot rates only after scope is equal. One contractor may include tear-off, dumpster, and trim replacement while another does not. A $5 per square foot bid is not better than a $6 bid if the $6 bid includes teardown and re-sheathing. Compare square counts and line items.

Can I reduce labor cost by installing siding myself?

You can cut labor cost, but you take on layout mistakes, flashing errors, and manufacturer warranty risk. Siding fails at junctions, not in the field. If you do your own install, focus on flashing windows, doors, and corners. Hire an installer for the trim package if you are unsure.
