How Much Do Storm Windows Cost?

If your windows are leaking air or are exposed to bad weather on a regular basis, exterior storm windows may seem like the most cost-effective option compared to fully replacing every window in your home. And while they are certainly cheaper and easier to install, there may be some unforeseen costs that creep up unexpectedly.

The cost does not stop at the initial purchase price. It is important to factor in installation, repairs, maintenance, and additional features you may want for added protection. We’ve calculated the anticipated costs of exterior storm windows and have broken it down for you so you can make the right decision when it comes to sealing and protecting your windows.

Exterior Storm Windows: A Brief Overview

Storm windows come with a host of benefits, especially for those concerned about energy costs and bad weather conditions. There are many types and styles to choose from, but their purpose is largely the same across the board.

Here are some of the pros and cons to take into consideration when looking to invest in exterior storm windows.

Pros

The biggest benefit of exterior storm windows is that they are a much cheaper option compared to replacing the entire window. So, if your windows are old, expelling air, or at risk of environmental damage, exterior storm windows are a great way to add some extra protection while saving money upfront.

Exterior storm windows are also preferred because they can sometimes blend into the home to maintain curb appeal. Some storm windows are designed to be difficult to see or distinguish from the existing window frame. Some can stand out and add an extra pop of color, so you can get a design upgrade at the same time.

They are known to provide protection from storms, but some storm windows also provide protection from UV rays. Storm windows can provide some noise reduction, but because of their weep holes, they aren’t recommended if this is your primary issue.

Properly installed exterior storm windows also prevent air leakage and aid in heat retention which helps cut costs on energy bills and creates a greener home.

Cons

While the benefits of exterior storm windows seem appealing, there are a few considerations that may have you continuing your search for replacement window alternatives.

Exterior storm windows can be tricky to install because of their bulky and heavy characteristics. They usually require a professional to ensure they are put in properly, especially when trying to install them in hard-to-reach places. If you’re trying to install these windows yourself, using a ladder to reach higher stories is dangerous and can put you at risk for serious injuries. Plus, if these windows are installed wrong, they won’t serve their purpose.

They also can be difficult to remove which may need to be done seasonally if you want to be able to open your windows during the warmer months. That means you may have to remove and reinstall the storm windows every year, taking up a lot of time and money. They also generally require more maintenance than your normal windows.

While they do help with heat and cold protection, there are better options available if that is the main goal. Condensation buildup between the regular window and the storm window is also possible if not properly installed.

And depending on where you live and the type of home you have—especially if you live in a historic home— exterior storm windows may not pass approval.

Exterior Storm Windows Cost

Storm windows may save you money on replacement windows and are more cost-effective upfront than some other alternatives, but maintenance and upkeep can cause some unforeseen costs. These unexpected expenses may help you decide whether or not they are worth the investment.

Here are some extra costs you should anticipate when choosing to install exterior storm windows.

Repair & Replacement

Exterior storm windows act as a layer of protection for your actual windows. But being on the frontlines of defense against storms and the elements, the storm windows will likely get damaged at some point. While the cost to repair or replace the storm windows is cheaper than replacing the existing windows, it can still take a chunk of money out of your wallet.

On average, repairing a storm window costs between $25 and $200 a window. You may be able to repair it on your own, but the materials and labor to do so normally cost more than hiring a professional.

However, sometimes a storm window is damaged beyond repair and needs replacement. Depending on the materials and the shape of the windows, this can cost from $100-400 per window, depending on the material. That is a costly investment to upkeep.

Maintenance

Storm windows do require quite a bit of maintenance to keep them working properly and effectively. They need to be cleaned, and the tracks need to be lubricated regularly every season. They may also need new caulking to prevent air leakage.

These things aren’t too expensive or time-consuming to do, but the costs can accumulate over the years. Also, it may be hard to clean, lubricate, and caulk exterior storm windows located on higher floors. Maintaining the storm windows in multi-level buildings can prove to be challenging and may not be worth the safety risk and time investment.

Installation

When calculating the upfront cost of exterior storm windows, it is important to factor in the installation costs to get an accurate estimate. Depending on the size and how easy it is to install, installation is expected to cost from $65 upwards per window.

This quickly adds up when looking to cover every single window in the home, and the cost increases with difficult installations, like multi-story houses. In addition, you can expect expenses to elevate during labor or material shortages.

With this being said, it is still better to leave the installation up to the professionals to ensure the storm windows are working properly and effectively serving the purpose you purchased them for.

Removal of the Old Storm Window

Obviously, installation is going to cost money, but so does removing the windows. Removal may have to take place if you want to replace the storm window with a new one or with another alternative.

This can cost between $25 and $50 per window, including the labor to remove the windows and the cost of disposal. Again, it does not seem like a steep price for a single window but quickly becomes pricey when looking at multiple removals.

Screens

Not all exterior storm windows come with screens. This may not seem like an issue during the colder months, but if you want to open the windows for a cool breeze during the summer without bugs flying in, you will want the screens. This can mean an additional cost of $20-$50 per window to have them added.

Stabilizer Bars (Optional)

Stabilizer bars are optional and not always necessary, but they add more structural strength to the windows. This can increase the durability and add to the lifespan of the storm windows, which saves costs in replacements. The stabilizer bars cost between $20-$40 per bar.

Weatherstripping (Optional)

Weatherstripping increases the effectiveness of the storm windows by sealing the edges to make them more airtight. This helps with the home’s energy efficiency and is recommended for areas with extreme climates. The entire weatherstripping would cost around $200.

To make it easier on you, we made a chart that breaks down each expense and the average cost:

Expenses Cost Range
Repair Cost $25 - $200 per Window
Replacement Cost $100 - $400 per windows
Installation Cost $65+ per window
Removal Cost $25 - $50 per window
Screens Cost $25 - $50 per window
Stabilizer Bars (Optional) $20 - $40 per bar
Weatherstripping (Optional) Around $200

Indow inserts were easy to measure, order and install. They've provided great insulation for old single-pane and stained glass windows in an antique home. We can significantly feel how much better the home holds heat.

I ordered two Indow inserts for my home. They are doing a great job, entirely happy with them and the ordering process.

I can't say enough good things about this product and company. Our house is 101 years old and the sidelites next to our front door are single pane ancient wavy glass which means when it gets very cold (Chicago temps) we can have an inch of frost covering the INSIDE of our windows. I was desperately searching for a solution so our front vestibule was not so cold and a friend recommended Indow. The process could not have been simpler and the temperature difference it has made is off the charts.

I have several historic single pane gridwork mullion windows. They're beautiful but have almost no thermal protection. Indows proved to be the perfect solution to preserve these windows while getting the thermal comfort we need. They were easy to install and work perfectly!

Amazingly easy to install even the safety chain holders. I. Noticed an immediate sound level difference and the room atmosphere became more solid feeling and pleasant. They also gave an insulating feature to the window drafts are non existent! The house is 50ft off a State highway that is heavily traveled in warmer months I'm confident the indows will handle it. I'm very pleased!

We ordered the acoustic inserts to help with road noise, and we've been sleeping so much better with them!

We used the windows inserts in our skylight. They are great! They the horrible drafts and noise out and were cost efficient. My only comment would be to provide better measurement and installation instructions for skylights specifically. It took us a lot of guessing and research to measure and install because skylight directions were not provided and the windows install guide doesn't always apply to skylights. Other than that though great product and I would buy again!

Our home was built in the late 1800s and we have spent a lot of money over the last 20+years restoring it.We did not want to replace the windows with modern windows because of the cost and originality. But the single pane windows come with a price also. the main reason we purchased the Indow window inserts is because of the condensation on the inside of the windows.We would literally have a take a towel and wipe them down every morning in the winter. There would be a puddle on the sill,and wood and water dont get along to well. SO we looked into the best solution to our problem and found Indow. Was reluctant to spend that much money but am super glad we did!! They have been installed now for over two months and our condensation problem has been virtually eliminated.!!! AND our furnace does not run as much as it did before. Over all it was money well spent!! The process was a little scary at first but they have a simple formula. And our contact person,Reed was awesome. Answered any questions i had and was always available.

Used to block interior side of a garden window in the the kitchen. Without insert, cold air literally poured into the kitchen making a winter jacket almost mandatory when preparing meals or washing dishes

Highly recommend! The team (Brian) took time to help me figure out the best solution. They were made and delivered faster than expected. It was very rewarding to install them because I could feel the cold air get squeezed out as they went flush against the single pane of glass. Solid quality and great fit.

My inserts fit beautifully into my 125 year old windows - many of which were 5 feet tall. Easy to unwrap and install. Great product and even better service! I liked the process of measuring the windows with a laser measuring tool which was easy to use and precise. The product came in good condition after shipping across country and was well marked. The customer support was excellent.

Received our Indow Windows and can tell they are blocking a lot of the noise we could hear. Right now the weather is mild, but hoping to notice a big difference when the summer heats up. Our house is in a historic district and we cannot change our windows. They are very drafty and thin glass. We only ordered two, but we are in the process of ordering for four more. Love that we don’t need to drill holes or anything and they just pop right in.

Every thing arrived in perfect condition, thanks to the very secure packaging. Windows fit as expected, although quite tight. After installation we noticed that the cold drafts were gone and the room felt a lot warmer. We are very satisfied with the product and the result.
