What Does Window Replacement Cost?

Windows are often one of the most overlooked design features of a house. But old and dated-looking windows can quickly hurt your property value and damaged or deteriorating windows can hurt your energy efficiency and result in issues like condensation and mold growth.

As a result, homeowners may replace their windows for a number of different reasons. These can include:

  • Replacement or repair after damage
  • Updating the look of your home
  • Improving energy efficiency and reducing utility costs

While there are potential cost savings, or an opportunity to make more money through increased property value, undertaking a window replacement can be expensive, particularly if you’re dealing with a whole room or a whole house.

How much window replacement costs will depend on a number of factors, such as:

  • Are you replacing the glass, sash, frame or the whole unit?
  • What materials will you use?
  • How old are your windows and are replacement parts available?

Depending on the age of your windows and how long you’ve been in your home, it’s possible that you may not have all of this information available. Because well-manufactured and properly installed windows can last for decades, they may have been in your home longer than you’ve owned it, making it hard to identify important details like the window make and model.

As a result, it’s often easy for many contractors to tell you that the full window needs to be replaced, and that replacement parts aren’t available for older windows, particularly wood ones. Or else they might say the cost of wood window replacement is too high.

It’s true that, on paper anyway, the starting cost of a new wood window may be more expensive than a vinyl one. But wood window repair may be a more available option that you’d initially think, and there’s more to window replacement cost than what the frame is made of.

Here are some factors to consider when calculating the cost of replacement:

  • Replacement glass: If you’re replacing your windows for energy efficiency purposes, not because they’re damaged, then you may need to only replace the glass. A single pane window could cost as little as $47, but isn’t very energy efficient. A low-E or triple pane window will cost $110 to $128 dollars, while a double pane window is about $96.
  • Window style: A big bay window may be a great feature, but bay window replacement costs can be as high as $3,500. By comparison, a classic wood sash window can be as little as $300.
  • Materials: Yes, wood is more expensive than vinyl, but it’s still generally less expensive than steel or fiberglass. And replacement wood window sashes can come in a variety of colors and can be painted or stained to match existing fixtures, shelves or cabinets in your home, giving you greater design flexibility.
  • Labor: Labor rates vary across the United States and can add $100 to $200 or more per window. When you’re speaking with contractors, ask them about which suppliers they use for window replacement, what experience they have with wood window repair and how they source parts to repair and replace older wood windows.

So which window manufacturer should you choose when looking for wood replacement windows?

Pella and Andersen are the leading manufacturers of replacement windows in the United States. When talking to contractors about window replacements and costs, many will recommend either Pella or Andersen products.  

Both companies offer four different lines of wood windows. Prices for Pella range from $170 for a 450 Series/ProLine wood window to $1,800 for the Architect Series Reserve line.

For Andersen, the base price for a 200 Series wood window is $265 and can extend to $1,650 for their Architectural Collection A-Series windows.

By comparison, Fenster’s wood window repair and replacement sashes are priced affordably and are compatible with a number of older window manufacturers including:

  • BiltBest
  • Caradco
  • Craftline
  • Hurd
  • Kolbe
  • MW
  • Malta
  • Norandex
  • Norco
  • Pozzi
  • Rockwell
  • Sealrite
  • Semco
  • SNE
  • Weathervane

If you’re not sure what type of window you have, tips for identifying individual models can be found here.

Fenster’s Quiksash Clad/Wood Casement Sashes are guaranteed to work and perform at a much higher level than the original window by deleting engineering flaws like boot glazing and exterior glazing stops. And with a starting price of $345, these sashes are priced comparably to the leading brands. Similarly, our Double Hung Sash Kits start at $399, making them competitively priced.

And since all Fenster sashes come standard with low-E glass and weatherstripping, your home will benefit from added energy savings.

To order replacement sashes, you’ll need a few measurements:

  1. From outside the window, measure the width of the sash from outside edge to outside edge, and the height of the sash from the top edge to the bottom edge.
  2. Do not measure the glass opening or weatherstripping.
  3. Some wood sashes may bow over time. You should measure in different places and use the most common measurement you get.
  4. On cladded sashes, it is okay to measure from edge to edge of the cladding. We will size the wood frame to accept the cladding.
  5. To measure double hung sashes, it is sometimes easier to tilt the sash toward you inside the house to get a better measurement of the exterior side.
  6. Enter your width and height in the corresponding size ranges on the sash quote section to get your quote. These exact measurements will be required at the order stage.

You’ll also need to know what kind of window you have:

  • Stationary windows are the simplest. A single fixed pane of glass in a sash.
  • Single hung windows feature two panes of glass in separate sashes, where one pane is fixed and other is on a track so it can be slid up and down.
  • A double hung window is similar to a single hung, but both panes are able to slide.
  • Casement and tilt windows don’t slide like hung windows but open on a hinge or with a crank.
  • Awning windows hinge horizontally, usually from the top, to let in air.
  • Picture windows are fixed, but typically larger than a standard stationary window, to let in more light.
  • Sliding windows, like sliding doors, slide on a horizontal track, rather than hung windows which slide vertically.

Once you’ve collected this information, reach out to Fenster to discuss a quote for you quality replacement windows at a competitive cost.

    I have MW windows in my sunroom and 2 windows show cloudy window panes. Can I buy the double paned glass and replace this myself. Do you have the double panes in stock or instruct me where to purchase these?

      Hi Paul, Sure! Just about any residential glass company can either get you the glass, or do the whole project for you. We don’t sell just the glass, basically because its too expensive and dangerous to ship. I’d look a couple glass shops there in your area and see if they can help you.
