Repairing Home Windows Yourself: What Does It Cost?

Discussing the Cost of Replacement Windows

Replacing windows is a lot easier and cheaper than adding a new window. All you have to do is install the windows from the inside, so you don’t have to remove any stucco or trim on the exterior. New installation requires alterations to the trim and parts of the wall and removal of the outside trim.

Costs to hire a pro

In addition to the cost for the window and any accessories, you will have to pay an hourly rate for installation. A professional will determine the rate based on the sum of the length and width of each window, so a 50 x 65 inch window would be 115 united inches. The rate will also be based on:

  • Removal of existing windows
  • Installation of new windows
  • Dispose of the old windows
  • Cleanup
  • Washing the new windows

If dry rot or other damage exists, repairs will have to be made before the new window can be installed. This will increase installation and labor costs.   

If your existing window frame is rotted or damaged, it will have to be replaced with a new frame. New construction windows can cost 50 to 100 percent more than replacement windows.

Costs to Do It Yourself

Installing replacement windows yourself will take several hours, but it won’t cost as much as hiring a professional. Once the installation costs have been eliminated, your costs to install the windows on your own will include:

  • The window. Depending on the style, material, and size, the cost for a replacement window can range from $200 to $1,000 or more. For example, wood and steel are more expensive than aluminum and vinyl, and Andersen and Pella windows are more expensive than PGT or Feldco. Small windows require less material, so they are less expensive than large windows.
  • Tools. To install the windows you will need a caulking gun, a chisel or ice pick, drop cloths, a hammer and nails, a level, pry bar, reciprocating saw, utility knife, and a tape measure.
  • Cleaning supplies. Although the cost for cleaning supplies is the smallest expense, it’s still a good idea to include it in your budget. You’ll need a vacuum cleaner, sweeper or dust buster, soap and water, cloths for clearing excess caulking and other materials, a mop or wet-jet if installing around hardwood floors, glass cleaner, and paper towels.
