How Installing Energy-Efficient Windows in Alexandria Saves You Money

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

  • Better temperature control in your home: Living in a hot place like Alexandria can often mean relying on your AC to keep your home cool. Energy-efficient windows can lower how hard your AC needs to work to cool your home.
  • Reduce your carbon footprint: By using less energy once switching to energy-efficient windows, you'll also be cutting your carbon dioxide emissions by about 12%, according to Energy Star.
  • Protect your investment: If you have an older home, your windows are most likely outdated. Updating your windows can make your home more comfortable and also help raise the value of your home if you decide to sell.
  • Better temperature control in your home: When you reside in a place like Alexandria where the winters can be very cold, you usually have to depend on your heater to keep your house warm. Energy-efficient windows can cut back on how hard your heater needs to work to heat your home.

Estimated Cost of Window Replacement in Alexandria

Windows come in varying shapes and sizes, so costs and services will differ tremendously. Here are the typical costs and the primary services that you can find from window installers.

How Much Do New Windows Cost?

The national average cost to install a single window is about $600 but can range from $200 to $1,200. This is because window installations depend on a variety of factors specific to your home, including the size, material and number of windows you need to replace, as well as where your property is located.

It's also worth noting that energy-efficient windows will cost more upfront, but Energy Star predicts that switching out the windows on your Alexandria home translates to an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. How much you'll save by switching to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.

We recommend getting free quotes from several window installers to find the one that works best for you.

What Services do Window Installers Offer?

There are generally two kinds of window replacement services: full-frame and pocket installations.

A full-frame installation replaces the total window, such as the sill, frame, trim and the window panes. As this kind of installation requires more time and labor, it will cost more than a pocket installation. Pocket installations (or retrofits) involve replacing a window within the existing frame, which makes pocket installations take less time and therefore cost less. But, if the frame has any damage or rot, you should opt for a full-frame installation instead.

Your window installation company will be able to recommend the best type for your project. In Alexandria, the choice will mostly be based on how much damage there is currently and how old your existing frames are.

How We Choose the Best Window Installers in Alexandria

The EcoWatch Reviews team is different from other reviewers, as we evaluate these companies through a sustainability lens. We've assessed the best window installation companies in Alexandria primarily based on energy efficiency, as it's what's best for the environment and for you as a homeowner. Energy-efficient windows can cut your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

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 picking new windows, the quality and breadth of services often plays just as important of a role in overall efficiency and performance as the type of window you opt for. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

We analyzed trends in recent customer feedback to determine the companies with the most consistent customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it indicates the quality of services across most other categories, including quality of installation, quality of parts, cost, 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 as low as possible. When analyzing providers' prices, 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

Lastly, we like to see companies that have been in the industry for quite some time. Window installation companies that have more years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.

Alexandria, VA Window Replacement FAQs

What is the average cost to install windows?

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

Which type of window is the best?

A window's energy efficiency is affected by several 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 and are certified 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 time needed to replace your own windows, we recommend hiring the pros. The process of installing windows is quite involved and can take anywhere from four to six hours for a single window. Although it's tempting to try to save some money by doing it yourself, hiring a professional is a faster, more efficient and safer alternative.

When is the best time of year to replace windows?

Even though you can install windows any time of year, warmer weather is usually better for replacing windows. In addition, the weather should be dry, since rain can make the installation more difficult.
