A guide on the best window replacement companies in Great Falls may not seem like the most interesting article on the EcoWatch site, but trust us, windows have a more direct impact on your life than you might realize. The Department of Energy estimates that heat gained or lost through outdated or drafty windows could make up close to 30% of heating and cooling costs. In Great Falls, where the energy bills are an average of $48 per month, that’s almost $$173 per year wasted.

Thankfully, saving you energy with upgraded windows also aligns with our goals of conserving energy and the resources it takes to make it.

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 upgrade to energy-efficient windows, you may see a few benefits, including:

  • Protect your valuables from fading: When you switch to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will fade less because of their ability to filter out damaging UV rays.
  • Reduce your carbon footprint: Since energy-efficient windows improve the insulation in your house, you can reduce your indirect greenhouse gas emissions by about 12%, according to Energy Star.
  • Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its value, particularly if your home is on the older side.
  • Save money on power bills: Since energy-efficient windows decrease the amount of energy used to heat or cool your home, the switch can help you save around $359 annually on your energy bills in Great Falls.

Estimated Cost of Window Replacement in Great Falls

Windows come in various styles, purposes and shapes, so costs and services will differ tremendously based on your project. Below, we go over the typical cost and services that you’ll find from window installation companies.

How Much Do New Windows Cost?

Generally, Great Falls homeowners can anticipate their window replacements to range from $250 to $1,200. The most common installations sit 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+ a year after replacing single-pane windows.

We advise getting free quotes from multiple window installation companies to find the right windows and the company that works best for you.

What Services do Window Installers Offer?

The first question to ask yourself when getting new windows is: Should you get a full-frame installation or a pocket installation?

Full-frame installations are usually done when you want a new style or your window has a lot of deterioration. With this service, your installers will replace the complete window, including the sill, trim and frame. A pocket installation involves replacing a window within the existing frame, which is generally cheaper than a full-frame installation.

If you’re still trying to decide which kind of installation to get, you can talk to your installer and get their recommendation. The decision mostly is influenced by the age of your window frames and if there’s any damage.

How We Choose the Best Window Installers in Great Falls

EcoWatch reviews differ from most reviews since we assess these companies through a sustainability lens. Along with energy efficiency, we evaluated each installer and assigned rankings using the following methodology:

Service Area

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

Work Quality

When picking new windows, the quality and variety of services can often play just as important of a role in overall efficiency and performance as the type of window you get. We do rate window installers higher if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

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

Cost

Cheaper windows certainly don’t mean better windows, but we know many of our readers try to keep costs as low as possible. When analyzing providers’ prices, we awarded higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

As discussed previously, windows are a significant investment, so you’ll want to make sure that investment is protected. Window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Lastly, we like to see companies that have a proven track record in the industry. Window installation companies that have more experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.

Great Falls, VA Window Replacement FAQs

How much should a window install cost?

The average cost of replacing a window can range between $450 and $650. There are a variety of factors that influence how much it costs, including the number of windows, local labor costs, how energy-efficient the windows are, styles and sizes of windows, the materials used in designing the windows and your property’s location.

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 do not open are more efficient than windows that do. If you want to be sure you’ll have the most energy-efficient windows, look for models with the blue Energy Star certification — they’re certified energy-efficient by the U.S. Department of Energy.

Do I really have to use a window installation company?

Unless you’re handy and have the time needed to replace your own windows, we recommend hiring the pros. The window installation process is complex and can take anywhere from four to six hours for a single window. Although it’s tempting to try to do it yourself to save money, hiring a company is a faster, more efficient and much safer alternative.

Should I replace my windows all at the same time?

If you’re upgrading your windows to get more efficient windows, replacing all your windows at once is the only way to see a noticeable difference. However, if you have only a few windows that are broken or leaky, you can replace just those.
