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 McNair Saves You Money

By upgrading to energy-efficient windows, you and your family can enjoy several benefits, such as:

  • Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes tend to have windows that are outdated, drafty or maybe even damaged in some way. Upgrading your windows could help raise the value of your property if you decide to sell.
  • 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.
  • Save on power bills: Since energy-efficient windows lower how much energy you need to heat or cool your home, they can help you save about $359 annually on your energy bills in McNair.
  • Decrease your carbon footprint: You can reduce your carbon footprint by about 12% after you install Energy Star certified windows. In McNair, that’s about 376 pounds per year on average.

Estimated Cost of Window Replacement in McNair

Let’s go over the cost of window replacement and the kinds of services offered by installers.

How Much Do New Windows Cost?

On average, homeowners in McNair can expect that most window installations will range from $250 to $1,200, with the most common installations sitting at about $600. How much it will cost depends on several factors, like size, the location of your home, type, number of windows, material and more.

It’s also worth keeping in mind that energy-efficient windows will cost more initially, but Energy Star predicts that upgrading the windows on your McNair home translates to an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. How much you’ll save by switching to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.

How much your window installation costs will also vary based on the kind of window material you choose for the frames. Wood windows are typically the most expensive, though it depends on whether they are 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are more efficient.

What Services do Window Installers Offer?

The first step when planning a replacement is to think about whether you should get a full-frame or pocket installation.

A full-frame installation is a replacement of the total window. This service involves removing the old window, the sill, and the exterior and interior trim. It also involves additional materials, such as insulation and drip edges, which raise the overall cost of the project. Also worth noting: you may have to touch up the paint surrounding the window after a full-frame installation. A pocket installation entails replacing a window without removing the entire frame, which is usually less expensive than a full-frame installation.

If you’re hiring a reputable window installation company, your company will be able to recommend the best type for your project. In McNair, the decision will mostly depend on the efficiency of your home and the age of your existing frames.

How We Choose the Best Window Installers in McNair

EcoWatch differs from most reviewers because we evaluate these companies through a sustainability lens. We have decided to review the top window installation companies in McNair primarily based on their energy efficient offerings, as it’s the most sustainable option and the best one for homeowners. Energy Star certified windows can lower electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

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

Work Quality

When installing new windows, the quality and variety of services often plays 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

Customer feedback is another very important review factor. If most customers don’t have nice feedback about their experience with a certain company, you won’t see it featured on EcoWatch.

Cost

This one is a give-and-take: as with other services, cheap window companies won’t always provide the highest quality service. Still, we want to ensure 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. For that reason, window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

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

McNair, VA Window Replacement FAQs

What is the typical cost to replace windows in a home?

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

What type of window is the best for energy efficiency?

A window’s energy efficiency is influenced by a number of factors, including the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are often the most energy-efficient since they are certified by the U.S. Department of Energy.

When do I have to use a window installation company?

Unless you’re handy and have all the necessary tools 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 save money by doing it yourself, hiring a company is a faster, more efficient and safer alternative.

Should I replace all my windows at once?

If you’re upgrading your windows because of energy-efficiency, replacing all the windows together is the only way to see a noticeable difference. On the other hand, if you have only a few windows that are damaged or leaky, you can replace just those.
