What’s in these numbers

Each total is a typical job, priced the way a contractor’s estimate is priced:

  • Vinyl siding, standard lap profile, over the wall area.
  • Tearing off the old siding first.
  • House wrap under it. The residential code calls for a water-resistive barrier behind siding (IRC R703.2).
  • Overhead and profit: 20%, the standard markup on a contractor’s estimate.
  • Sales tax on the materials, at the state’s average rate.

The sizes are square feet of wall, not of floor. A one-story house 50 by 30 feet with 8 foot walls has 2 × (50 + 30) × 8 = 1,280 square feet of wall, plus about 225 in its two gables at a 6/12 pitch.

Not in them: corner posts, J-channel and trim around windows and doors, soffit and fascia, insulated backer, rotten sheathing, and a dumpster.

What moves the price

  • Trim and openings. Every window and door is trimmed with J-channel, and every corner gets a post. A house with many windows costs more per square foot of wall.
  • The siding. Thicker panels, insulated vinyl, shakes and board-and-batten profiles cost more than standard lap. The siding replacement cost guide puts vinyl beside fiber cement and cedar.
  • Stories. Second-story walls and tall gables need ladders, staging or lifts.
  • What’s under the old siding. Rotten sheathing gets replaced before the new siding goes on.
  • Where you live. Pick your state in the box above.

Measuring the wall area

  1. Measure each wall’s length and height and multiply. For a gable, the triangle is the width times its height, divided by 2.
  2. Add the walls up. Small openings are usually left in, since the siding is cut around them anyway. The guide to installing vinyl siding covers the job itself.
  3. Type the total into the box above for the range at that size. The siding calculator works out the wall area, squares and trim for a whole house.

Common questions

How much does it cost to side a 1,500 square foot house?

It depends on the wall area, not the floor. With about 1,500 square feet of wall, the price per square foot above puts it at about $9,700 to $14,700, before trim and corners.

How much does vinyl siding cost on a 2,000 square foot house?

A mid-size house with 2,000 square feet of wall comes to about $13,200 to $19,400, typically $15,900.

What does vinyl siding cost per square foot installed?

$6.50 to $9.75 a sq ft of wall of wall, with the tear-off, house wrap, overhead, profit and sales tax included.

How much does a box of vinyl siding cover?

Many boxes cover two squares, 200 square feet; the label on the box says.

Does insurance pay for siding?

When a covered event such as hail or wind damages it, a homeowner’s policy usually pays to repair or replace the damaged siding, subject to the deductible and the policy’s terms. The adjuster’s estimate itemizes the work.
