Siding costs by wall area, material and region — vinyl through fibre cement, including the wrap and trim that decide how long it lasts.

  • National average pricing. Pick your region to adjust for local labour rates.
  • This is a planning range, not a quote. Get three itemised bids and compare the scope line by line — the cheapest bid is usually the one that left something out.

What the estimate includes

  • Removal and disposal of existing siding
  • House wrap and flashing
  • Siding, corners and trim at the chosen tier
  • Caulking and paint or factory finish
  • Soffit and fascia where included in the bid

What it does not include

  • Sheathing or framing repair from water damage
  • Insulation upgrades behind the siding
  • Windows, doors and gutters
  • Lead-paint abatement on pre-1978 homes

What actually moves the price

  • Material. Vinyl, engineered wood and fibre cement are roughly a 1× / 1.6× / 2× progression installed, and fibre cement carries the highest labour cost because it is heavy and cuts slowly.
  • What is underneath. Siding hides the water damage it caused; sheathing repair is the most common change order on this job.
  • Height and detail. Two and three storeys need staging, and every gable, dormer and window surround is another set of cuts and flashing details.

How these estimates are built

  • Base costs are typical 2025–2026 US pricing per square foot at each finish level, drawn from national remodelling cost surveys and contractor bid data.
  • Your region multiplies that base — coastal metros run 30–40% above the national average and rural markets 15–20% below, almost entirely on labour rates.
  • The contingency is added on top of the base range rather than taken out of it, because that is how the money actually behaves on a job site.
  • The materials, labour and permit split shows how the mid-point of the range typically divides. It is a way to read a bid, not a second estimate.
  • Resale recoup figures follow national cost-versus-value patterns. No renovation returns more than it costs — treat the figure as a partial rebate on something you are buying for yourself.

Frequently asked questions

How much does it cost to side a house?

$5–$10 per square foot for vinyl, $10–$18 for engineered wood or fibre cement, and $18–$35 for cedar, stone or premium products. A typical 1,800 sq ft of wall is therefore roughly $9,000–$18,000 in vinyl and $18,000–$32,000 in fibre cement.

Which siding gives the best return?

Fibre cement consistently returns the most at resale — around 75–88% in national cost-vs-value studies — because it looks like wood, lasts decades and reads as a permanent upgrade to buyers.

Should I insulate while the siding is off?

If the walls are uninsulated or the house is pre-1980, yes. Adding exterior rigid foam or blowing the cavities is dramatically cheaper while the sheathing is exposed than it will ever be again.

Before you commit the budget, see it finished

Upload a photo and generate photorealistic versions of the finished space in any style. It is far cheaper to change your mind here than after the cabinets arrive.
