Why you can trust EcoWatch

Our panel of energy experts work tirelessly to create unbiased reviews and informative content to help homeowners make educated decisions. No other windows site has covered energy efficiency and sustainability as long as EcoWatch, which means we're going to help you find windows replacements that will save on your energy bill and put more money back in your wallet.

Although renewable energy sources like wind and solar are important when it comes to reducing your carbon footprint, improving your house’s energy efficiency can also have a big impact on home energy conservation. If your windows are outdated or damaged, you could be losing 25-30% of your house’s heat or cool air out of them.

That’s also bad for the environment, as the additional energy required by drafty windows increases your carbon footprint.

Efficient windows are particularly important in Great Falls, where winters are long and cold. According to Energy Star, switching to energy-efficient windows can save the average homeowner up to $390 a year.

How Installing Energy-Efficient Windows in Great Falls Saves You Money

There are quite a few perks of upgrading to energy-efficient windows. Some reasons you may want to consider making the switch are the following:

  • Decrease your carbon footprint: Because energy-efficient windows improve the insulation in your home, you can cut your indirect greenhouse gas emissions by about 12%, according to Energy Star.
  • Save money on power bills: Since energy-efficient windows reduce how much energy you need to heat or cool your home, the switch can help you save about $390 annually on your energy bills in Great Falls.
  • Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Updating your windows can improve the insulation in your home and also help increase the value of your house if you decide to sell.
  • Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.

Estimated Cost of Window Replacement in Great Falls

Let’s take a look at the cost of installing new windows and the types of services you may need for your home.

How Much Do New Windows Cost?

Typically, homeowners in Great Falls can anticipate that most replacement window installations will range from $250 to $1,200, with the most common installations sitting at around $600. But costs vary considerably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also offer door replacements, which will make your project cost more.

With windows, efficiency is the most important factor for most homeowners. High efficiency windows may cost more off the bat, but by increasing the efficiency of your home — particularly during the winter — they can give you many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save Great Falls homeowners $390+ per year after replacing single-pane windows.

Costs will also vary depending on the material of your frame. Aluminum frames cost the least. They’re sturdy, light and maintenance-free, but provide poor insulation. Vinyl frames are somewhat expensive and provide good insulation. Composite frames made from wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They’re also aesthetically pleasing and provide decent insulation for your home.

What Services do Window Installers Offer?

The first thing to ask yourself when considering a window replacement is: Do you need a full-frame installation or a pocket installation?

Full-frame installations are usually recommended when you want a new style or your window has a lot of rot or deterioration. With this service, your installers will replace the full window, including the sill, trim and frame. A pocket installation means replacing a window within the existing frame, which tends to be cheaper than a full-frame installation.

If you’re still debating which kind of installation to get, you can talk to your installer and get their advice. The decision mostly depends on how old the frames are and if there’s any damage.

How We Choose the Best Window Installers in Great Falls

In our search to find the most reliable, eco-friendly window installers in Great Falls, the EcoWatch team chose the above companies as the best window installation companies in the city. Along with energy efficiency, we reviewed several window installers in Great Falls and assigned rankings based on the following methodology:

Service Area

This one is self-explanatory, but we’ve chosen to highlight window installers that serve the Great Falls area so you can find a quality window installation company near you.

Work Quality

When it comes to new windows, the quality and range of services can often play just as important of a role in insulation and performance as the brand you opt for. We do give window installers higher marks if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

We analyzed patterns in recent online reviews to find the companies with the most customer satisfaction. Customer satisfaction might be the factor we place the most value on, as it reflects the quality of services across most other categories, including professionalism, quality of installation, quality of parts, warranty, cost and more.

Cost

This one is a give-and-take: similar to most services, cheap window companies may not provide the most quality service. Still, we want to make sure we’re highlighting companies that provide a wide range of price and financing options so they’re accessible to most homeowners.

Warranty

Protecting your investment in new windows is important to many homeowners. That’s why window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Because of Great Falls’s climate, homeowners need to be wary of water damage, low efficiency and rot. We factored in local experience to reflect the ability of Great Falls window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.

Great Falls, MT Window Replacement FAQs

How much should window installation cost?

The average cost of installing one window can range from $450 to $650. There are many factors that influence how much it costs, such as how energy-efficient the windows are, local labor costs, the materials used in designing the windows, your property’s location, the number of windows and styles and sizes of windows.

What type of window is the best for energy efficiency?

Generally, double-pane windows will be more efficient than single-pane windows and windows that don’t open are more efficient than windows that do. To be sure you’ll have the most energy-efficient windows, look for models that have the blue Energy Star certification — that means they’re certified energy-efficient by the U.S. Department of Energy.

Do you really need to use a window installation company?

You should hire a window installation company whenever you need to replace your windows. Installing windows is a involved process that can be difficult to do on your own, so it’s best handled by the professionals.

Should I replace my windows all at once?

If your windows are greater than 20 years old, it’s most likely time to replace all of them. By that point, they are often less efficient, leakier and/or more damaged than new windows. Doing your windows all at the same time will involve less paperwork and less stress.
