Siding Replacement Cost

How much does it cost to replace siding?

When a building requires a complete replacement of the existing siding it will usually require the services of a professional contractor. Though some homeowners are able to tackle the installation of vinyl or even wood siding, generally it is not a standard DIY project.

The average home, according to the United States Census, is 2200 square feet and size, with a two-story design and footprint of 25'x45'. To determine the amount of siding needed for such a project requires a bit of simple math. The length of all four sides of the house are measured, and this figure is multiplied by the height of the walls. This means that the average home would require (25+25+45+45X20= 2800) 2800 of siding materials.

Cost breakout

For the purpose of this discussion we will take a look at the costs and requirements for replacing the vinyl siding on a home that requires 2800 square feet of materials.

According to CostOwl.com, the costs for a contractor to install mid-grade vinyl siding is between $250 and $300 per one hundred square feet. This means that the price range for the project we have describe here is $7000 to $8400. What would this include?

A good contractor will include:

  • Fascia, soffits, and window channels - some contractors tack on an additional fee of roughly $6 per linear foot when installing such components, but it is always best to select a contractor who will include this in the "per 100 square feet" pricing that they provide;
  • House wrap or insulation - there are some areas that demand the installation of a water and air vapor or insulating wrap be installed when siding is replaced. This just makes good sense, and according to InfoForBuilding.com, the cost for wrapping a 2000 square foot home is only $200 to $400; and
  • Trim, crown moldings and corner boards - these too are extra components, but most contractors do tack on extra costs for their installation. Be sure to establish the exact prices demanded before signing the contract - it should require no more than an additional $3 per linear foot.

Additional considerations and costs

  • Damage - Many homeowners are shocked at the amount of water damage, mold, or insect infestation that has occurred behind their older siding. This can add a tremendous amount of time and cost to the project. When working with a contractor on a siding replacement job it is important to discuss any such contingencies before the work begins. For example, most carpenters will require from $40 to $50 per hour for their services, and the contractor should assess the home and give the owners an estimate on the potential for repair work at such a rate or per hour cost; and
  • Disposal and removal - Most contractors will not place new siding over pre-existing siding and this means that the entire house will have to be stripped of the existing materials. This is a great deal of debris which tends to require fees for disposal as well. Generally, a contractor will bring a large dumpster to the site and charge the client a fee between $1000 and $3000 for this additional work.
