20 Best Window Companies in Alexandria, VA (2025 Reviews)

How Installing Energy-Efficient Windows in Alexandria Saves You Money

There are quite a few perks of upgrading to energy-efficient windows. A few reasons you may want to consider making the change include the following:

• Save on electricity bills: According to the Department of Energy, heat gained or lost through windows accounts for about 25-30% of household energy use. Switching to energy-efficient models can help decrease that amount, therefore saving you about 12% more on your bills.
• Reduce your carbon footprint: By using less energy once switching to Energy Star certified windows, you’ll also be lowering your indirect greenhouse gas emissions by about 12%, according to Energy Star.
• Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
• Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes usually have windows that are outdated, drafty or maybe even damaged in some way.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.

Estimated Cost of Window Replacement in Alexandria

Windows come in varying styles, purposes and shapes, so costs and services will differ remarkably based on your project. Below, we detail the average cost and services that you’ll find from window installers.

How Much Do New Windows Cost?

Typically, Alexandria homeowners can anticipate their window installations to range from $250 to $1,200. The most common installations sit at around $600. This is due to the fact that window installations are based on several factors specific to your home, including the size, material and number of windows you need to install, as well as the location of your property.

With windows, efficiency is the most important factor for most homeowners. High efficiency windows may cost more upfront, but by increasing the efficiency of your home — especially during the summer and winter — they can give you many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save Alexandria homeowners $347+ each year after replacing single-pane windows.

Another factor that influences the total cost is the material you select for your frame. Aluminum frames are usually 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?

In general, there are two types of window installation services companies offer: full-frame and pocket installations.

A full-frame installation is a total window replacement. This service involves taking out the old window, the sill, and the exterior and interior trim. It also involves extra materials, including insulation and drip edges, which raise the total cost of the project. It’s also worth noting that 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 whole frame, which is generally less expensive than a full-frame installation.

Your window installation company should be able to help you understand what’s best for your needs. In Alexandria, the decision will mostly be based on how old your windows are and if there’s any moisture damage. Wood can decay if not maintained properly over the years, so it’s good to have a professional examine your frames and window sills.

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 gave more points to companies that cover the city. There are certainly reputable providers that didn’t make our list because of the low odds that they would serve the average homeowner in Alexandria.

Work Quality

We’re certain that you’re looking for a company to do a great job installing windows. We’ve vetted each company on this list to ensure its technicians are well-qualified and that the company has gotten tons of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed patterns in recent customer feedback to find the companies with the most customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it indicates the quality of services across nearly every category, including quality of installation, quality of parts, warranty, cost, 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 providers’ prices, we gave higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

As discussed, windows are a hefty investment, so you’ll want to be certain that investment is well protected. Window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

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