Siding cost per square foot in 2026: vinyl, fiber cement and wood, and how siding quotes work

What vinyl, engineered wood and fiber cement siding cost per square foot in 2026, why wall area is harder to measure than roof area, and what a siding quote must itemise.

Siding is priced by wall area, and wall area is harder to pin down than a roof: every window and door is a hole in it, and every corner and opening needs trim. That is where siding quotes quietly diverge.

Fiber cement$10-$20Repaint every 12-15 yrs

How siding is measured

Wall area is the perimeter of the house multiplied by wall height, plus gable triangles, minus windows and doors. The perimeter can be read from satellite imagery, and storey count from a street photo, which gives a solid first range. Openings are an estimate until someone measures them.

Where siding quotes differ

  • Trim, soffit and fascia. Often a third of the job. Leave them out and a quote looks cheap.
  • Tear-off. Removing old siding and dealing with what is underneath.
  • House wrap and sheathing repair. Rot found on opening up is common on older homes.
  • How openings are handled. Some deduct them, some do not, and some charge extra to trim them.
Ask every bidder the same three things: total square feet, whether trim and soffit are included, and what happens if they find rotten sheathing. Different answers mean different jobs, not different prices.

What a siding quote must include

  • Wall area in square feet, and the product line — not just “vinyl”
  • Trim, soffit and fascia scope
  • Tear-off, disposal and house wrap
  • An allowance or rate for sheathing repair
  • Warranty on material and labour
