Siding replacement costs range from $5,000 for vinyl on a small house to $30,000+ for fiber cement or engineered wood on a large home. Material, house size, story count, and existing siding condition drive the final number. This calculator builds your estimate covering material with waste, tear-off, installation labor, trim, and margin.
Vinyl siding: $1.50–$4/sq ft materials. Fiber cement (James Hardie): $5–$10/sq ft. Engineered wood (LP SmartSide): $4–$8/sq ft. Cedar or redwood: $7–$15/sq ft. Stone veneer: $15–$30/sq ft. Add 10–15% waste factor for standard installs; more for homes with complex gables, dormers, or corner work. Measure by square (100 sq ft) for consistency with material ordering.
Tear-off of old vinyl or aluminum: $1–$2/sq ft. Tear-off of old stucco or wood: $2–$4/sq ft and requires more dumpster volume. New housewrap (Tyvek or equivalent): $0.40–$0.80/sq ft installed. Flashing at windows, doors, and roof lines: $1.50–$3/linear ft. These layers protect against moisture intrusion — cutting corners here creates expensive warranty callbacks.
Vinyl siding: $2–$4/sq ft labor. Fiber cement: $4–$7/sq ft (heavier, requires two-man lifts and specialized cutting tools). Engineered wood: $3.50–$6/sq ft. Cedar lap siding: $5–$9/sq ft including priming and painting. Multi-story work: add $0.50–$1/sq ft per story for scaffolding or lift rental. Trim work (J-channel, fascia, corner posts, window wrap) is priced by linear foot.
Window replacement bundled with siding: $400–$1,200 per window installed depending on type. Wrapping existing window and door frames: $25–$75 per opening. Soffit and fascia replacement alongside siding: $4–$10/linear ft for aluminum soffit; $5–$12/linear ft for fiber cement fascia. Bundle these as a package to increase average job size and reduce mobilization cost per project.
