While these prices may seem high up front, storm windows can save you money in the long run when it comes to energy efficiency.

In this guide, we’ll explain everything you need to know about the cost of storm windows and how they can be a great addition to your home. 

Key takeaways

• Unlike hurricane windows, which are used as standard windows, track storm windows are flat glass panels installed over your current windows and fit in your home's window frame.   
• Storm windows enhance insulation by sealing windows to prevent air infiltration from their impressive casement. 
• Typically installed in the winter, low-e storm windows prevent you from being able to open your windows and will need to be removed during the warmer seasons unless your home has AC. 
• Storm windows may increase your home’s value for a higher ROI if you were to sell. 
• For extra durability, it’s highly suggested to go with an aluminum frame.

Storm window costs

There is no one-size-fits-all cost estimate for storm window inserts. The exact cost fluctuates depending on the type of window you choose, its size, frame material, whether it’s double-hung, and location.

In addition to materials, installation is another factor to consider for cost. Labor installation usually costs an average of $67 to $123 per window, though if your contractor charges hourly, you can spend anywhere from $58 to $106 per hour. If your contractor is also adding weatherstripping to the windows, this is an extra $5 to $9 per window charge.

There are also other materials associated with installation, like stabilizer bars and window screens you can add to your project, but will come with an extra charge. The stabilizer bars that are used to reinforce the frame can cost between $20 to $40 per bar, while new window screens cost $35 to $69 each. If you’re replacing or repairing existing screens, the cost increases to $41 to $75 though you may have to spend more depending on extra work that needs to be done. 

Storm windows: the bottom line

For homeowners who live in regions that experience high winds on a regular basis or experience issues with insulation, storm windows can be the perfect solution for your home. But, because of their extra protection and energy efficiency, they usually come with a hefty cost.

If you think storm windows would be a helpful addition to your home, search for local window contractors in your area to consult with and plan your storm window project.

FAQ

What is the purpose of storm windows?

Storm windows give your home an extra layer of protection against high winds from storms while keeping the temperature inside regulated. They’re also constructed with reinforced frames to withstand the strength of hurricanes and flying debris, though they should not be considered as the only storm protection preventative. 

Are storm windows impact-resistant?

Storm windows can protect your home from flying debris, but the glass is not impact-resistant, meaning breakage and other damage are still possible.

What’s the difference between storm windows and hurricane windows?

Storm windows are often interchanged with hurricane windows (also known as impact windows), but it’s important to note that these are not the same types of windows, even though they have a few similarities. First, storm windows are installed over old windows, while hurricane windows replace standard windows.

The most notable difference between these two windows is that, unlike storm windows, hurricane windows are made with impact-resistant glass. Hurricane windows are slightly more durable than storm windows since they’re made to withstand hurricane winds and damage from flying objects or shards of glass. 

How much do storm windows cost?

On average, a set of new 8 storm windows costs $2,090. Low-end storm windows average $812, while high-end storm windows average $8,032. The only way to discover an exact figure for your home’s new storm windows is to consult with a dealer nearby, as several factors, such as size, type, and location, determine the overall cost.

Can you leave storm windows up year-round?

Yes, you can leave storm windows up year-round, but this does mean there is no window opening, which can become a problem if you rely on shade or a breeze to cool and air out your home. The only way to be able to open your windows is to remove your storm windows and then reinstall them in the winter.

Another drawback to leaving your storm windows up year round is that it becomes difficult to clean. Dust, dirt, and cobwebs can build up within the space between your storm and existing windows, so you will once again have to remove them to clean all sides and remove any build-up.
