Great Falls Window Cost Calculator

Calculate how much you can expect to pay for window installation and replacement in Great Falls, VA using our customized window cost calculator.

Estimated Window Cost:
161 homeowners have requested a free estimate in the last 3 days.

Estimates will vary based on window dimensions and other unique factors to your home. Getting in touch with a local window installer is the best way to get an accurate cost estimate for your home.

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

When you switch to energy-efficient windows, you may see a few benefits, such as:

  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, reducing fading of your furniture, carpet and other valuables.
  • Reduce your carbon footprint: In Great Falls, you can lower your indirect greenhouse gas emissions by about 376 pounds per year when you install energy-efficient windows.
  • Protect your investment: When you have an older home, your windows could also be outdated or leaky. Upgrading your windows is an important part of maintaining your property and its value.
  • Save money on electricity bills: According to the Department of Energy, heat gained or lost through windows accounts for about 25-30% of household energy use. Upgrading to energy-efficient models can help decrease that amount, therefore saving you about 12% more on your bills.

Estimated Cost of Window Replacement in Great Falls

Each window installer offers various services and has varying prices depending on several factors.

How Much Do New Windows Cost?

On average, Great Falls homeowners can anticipate their window replacements to range from $250 to $1,200. The average cost sits at approximately $600. How much it will cost depends on several factors, including type, size, number of windows, material, the location of your home and more.

With windows, efficiency is one of the most important factors for many homeowners. High efficiency windows may cost more off the bat, but by increasing the efficiency of your home — particularly during the summer and winter — they can provide decades of energy savings. According to Energy Star, buying certified energy-efficient windows can save Great Falls homeowners $359+ each year after replacing single-pane windows.

Costs will also vary based on the material of your frame. Aluminum frames have the lowest price. They’re sturdy, light and easy to maintain, but offer poor insulation. Vinyl frames are a bit more expensive and offer good insulation. Composite frames made from wood fibers encased in plastic also provide 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?

There are typically two types of window replacement services: full-frame and pocket installations.

Full-frame installations involve replacing the full window, including the frame, trim and sill. You most likely need a full-frame installation when you want to change the style of your windows or your window has significant damage. Because these installations are more involved, they will increase overall costs. A pocket installation entails replacing a window without removing the entire frame, which tends to be cheaper than a full-frame installation.

If you’re still trying to decide which kind of installation to get, you can consult with 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

EcoWatch reviews are different from other reviews because we look at these companies through a sustainability lens. Along with energy efficiency, we analyzed each installer and ranked them using the following methodology:

Service Area

This one is pretty self-explanatory, but we’ve chosen to highlight window installers that serve a wide variety of states and cities so you can find a quality window installation company near you.

Work Quality

When installing new windows, the quality and variety of services can often play just as important of a role in overall efficiency and performance as the brand you get. We do give window installers more points if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

Customer feedback is another super important review factor. If the majority of customers don’t have good things to say about their service from a certain window installation company, it won’t be featured on EcoWatch.

Cost

This one is a give-and-take: similar to most services, cheap window companies are not going to provide the most quality service. On the other hand, we want to make sure we’re highlighting companies that provide a spectrum 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 that offer 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 these issues. If a company has less than 10 years of experience, it loses points in this category.

Great Falls, VA Window Replacement FAQs

How much should a window install cost?

The typical cost of replacing a single window can range from $450 to $650. There are many factors that affect the cost, such as the number of windows, local labor costs, styles and sizes of windows, how energy-efficient the windows are, your property’s location and the materials used in designing the windows.

Which type of window should I get?

Generally, double-pane windows are more efficient than single-pane windows and windows that don’t open will be 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 attached to them — they’re certified energy-efficient by the U.S. Department of Energy.

When do I have to use a window installation company?

Unless you have experience with home improvement projects and have the tools needed to replace your own windows, we recommend hiring a professional installer. The window installation process is complicated and can take anywhere from four to six hours for a single window. Although it’s tempting to try to save money by doing it yourself, hiring a professional is a faster, more efficient and much safer alternative.

Should I replace my windows all at once?

If your windows are more than 20 years old, it’s probably time to replace all of them. At that point, they are often less efficient, draftier and/or more damaged than new windows. Replacing your windows all at once will involve less paperwork and less stress.
