Window Replacement Cost

How much does it cost to replace windows?

According to author Katherine Kally, the average price range for vinyl replacement windows is from $189 to $700, and this is only if the pre-existing opening is structurally sound and not in need of any enhancement or repair. The price also includes the costs associated with removal of the old window as well. She goes on to explain that a skilled DIY homeowner might save from $35 to $100 per window by tackling the job themselves, but most home experts indicate that this is something not normally done.

This means that it is standard procedure to hire a contractor for the replacement of one or more windows. For the purpose of this discussion we will take a look at the costs and requirements for performing a full replacement of all of the vinyl windows in the average modern home.

The modern home tends to have an average of ten windows and most measure roughly 40"x55" in size. This means that the average cost for such a project should fall into the $2000 to $7000 price range.

Cost breakout

Typical costs to replace all these windows include:

  • Removal - the contractor should properly remove all existing windows, and this requires work on the interior and exterior of the home. Naturally it is unwise to work with someone who wants to remove all of the windows at a single time, and who doesn't discuss the need to repair, upgrade, or replace moldings after the new window is in place. The contractor should also indicate, in advance, any costs associated with disposal of the windows and building materials too;
  • Repair - it is usually possible for the experienced installer to detect problems with leaks, mildew, or other structural issues before they begin their work. This is something that the homeowner will need to strongly discuss with the contractor before signing the contract and beginning the work. For example, what is the fixed price for replacing rotted framing or boards? How much will the homeowner be charged if an entire frame needs to be rebuilt? What are the fees for any interior "finish" work? Settling such issues in advance of beginning is important because ten rebuilt windows could bump up the $2000 to $7000 project well into the $5000 to $12000 price range instead ; and
  • Casings and efficiency - any new windows are usually going to improve the building's energy efficiency, but it is important to consider the costs of improving the efficiency of the window casings too. The professional installer should be able to seal or insulate the area surrounding the window to also decrease any air leaks or drafts that also increase household energy consumption.

Enhancement and improvement costs

  • Rebates - a good contractor will work with the owner to select the most appropriate windows for the budget. For example, they might encourage the homeowner to spend more on windows that are considered Energy Star rated in order to allow the owner to enjoy the federal, state, and even utility company rebates and incentives for the work.
