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 environmentally friendly energy sources like wind and solar are important when it comes to lowering your carbon footprint, improving your house’s energy efficiency can also have a considerable impact on home energy conservation. Drafty windows can cost you in energy bills. As a matter of fact, the Department of Energy estimates that about 30% of your house’s heat or cool air could be lost through your windows.

Luckily, helping you save energy with more efficient windows also aligns with our goals of conserving energy and the resources it takes to make it.

Because windows have such a big impact on your home, choosing the right company for you is a big decision to make. That’s why the EcoWatch team has created this list of the best window installation companies, so you can more easily make an informed decision.

Alexandria Window Cost Calculator

Calculate how much you can expect to pay for window installation and replacement in Alexandria, 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 Alexandria Saves You Money

Energy-efficient windows can offer benefits in several ways. Here are a few reasons you may want to consider making the switch:

  • Save money on electricity bills: Because energy-efficient windows decrease how much energy you need to heat or cool your home, they can help you save around $347 annually on your energy bills in Alexandria.
  • Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% when you install Energy Star certified windows. In Alexandria, that’s about 376 pounds per year on average.
  • Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
  • Protect your investment: If you have an older home, 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.

Estimated Cost of Window Replacement in Alexandria

Each window installation company offers various services and has varying price points depending on several factors.

How Much Do New Windows Cost?

Generally, homeowners in Alexandria can expect that most replacement window installations will cost between $250 and $1,200, with the most common installations sitting at about $600. But costs will vary significantly depending on the quality of your products, the number of windows you need, the current condition of your home and your location. Many window companies also offer replacement door installations and other add-ons like shutters, coating, baths and more. These extra services will increase overall project costs.

Keep in mind that energy-efficient windows may have a higher price, but Energy Star estimates the upgrade will save you between $101 and $583 per year when replacing single-pane windows and between $27 and $197 per year when replacing double-pane, clear glass windows. Your exact savings will vary depending on your local climate, energy rates and individual home characteristics.

Something else that affects the total cost is the material of the frame you choose. Aluminum frames are typically the least pricey and are sturdy and light, but they offer poor insulation. On the other hand, wood frames cost the most, as they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.

What Services do Window Installers Offer?

Generally, there are two types of window replacement services companies offer: full-frame and pocket installations.

Full-frame installations are usually recommended when you want to change the style of your windows or your window has a lot of deterioration. With this service, your installers will replace the total window, including the sill, trim and frame. A pocket installation means replacing a window without taking out the whole frame, which tends to be less expensive than a full-frame installation.

If you’re still debating which kind of installation you need, you can ask your installer and get their recommendation. The choice mostly is influenced by how old the frames are and if there’s any damage.

How We Choose the Best Window Installers in Alexandria

EcoWatch reviews differ from other reviews, as we assess these companies through a sustainability lens. Along with energy efficiency, we evaluated window companies all across the state and assigned rankings using the following methodology:

Service Area

Because this is a guide for Alexandria, we paid more attention to companies that cover the city. There are certainly reputable providers that didn’t make the cut because of the low odds that they would serve the average homeowner in Alexandria.

Work Quality

We’re willing to bet that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each installer on this list to ensure its contractors are well-qualified and that the company has gotten plenty of positive customer feedback to vouch for its service.

Customer Reviews

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

Cost

Cheaper windows don’t necessarily mean better windows, but we know many of our readers would like to keep costs low when possible. When analyzing the prices of providers, we gave higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

As discussed, windows are a substantial investment, so you’ll want to make sure that investment is protected. Window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Last but not least, we like to see companies that have been in the industry for a while. Window installation companies that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.

Alexandria, VA Window Replacement FAQs

How much should a window install cost?

The typical cost of replacing one window can range from $450 to $650. There are a variety of factors that influence the price, which include styles and sizes of windows, the number of windows, your property’s location, how energy-efficient the windows are, local labor costs and the materials used in designing the windows.

What kind 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. If you want to be sure you’ll have the most energy-efficient windows, look for models that have the blue Energy Star certification attached to them — this means they’re certified energy-efficient by the U.S. Department of Energy.

What services do window installation companies offer?

Window installation professionals cover the entire process — from replacing old windows with new ones to cleaning up afterward. Additionally, some companies offer window manufacturing, customization and repairs.

What time of year should I replace my windows?

Replacement windows can be installed during any season, but autumn might be best. No matter when you install them, the contractors will take steps to make sure that too much hot or cold air doesn’t get into the home, so the temperature outside isn’t necessarily a big factor. What’s more important than the temperature is that the weather should be dry.
