How Installing Energy-Efficient Windows in Reston Saves You Money

By upgrading to energy-efficient windows, you and your family can benefit in several ways, including:

• Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its value, particularly if you have an older home.
• Reduce your carbon footprint: Because 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 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.
• Save on energy bills: According to the Department of Energy, heat gained or lost through windows makes up around 25-30% of residential energy use. Switching to energy-efficient models can help lower how much energy is used in your home, therefore saving you about 12% more on your bills.

Estimated Cost of Window Replacement in Reston

Windows come in varying shapes and sizes, so costs and services will vary greatly. Here are the typical costs and the primary services that you’ll find from window installers.

How Much Do New Windows Cost?

Though the national average cost of replacing one window is around $600, it can range from $200 to $1,200. But costs will vary considerably based on the current condition of your home, your location, the quality of your products and the number of windows you need. A lot of window companies also offer door installations and other add-ons like coating, baths, shutters and more. These extra services will increase your overall project costs.

With windows, efficiency is the most important factor for many homeowners. Efficient windows may cost more initially, but by increasing the efficiency of your home — especially during the summer and winter — they can provide decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Reston homeowners $359+ a year after replacing single-pane windows.

Costs will also vary depending on the material of your frame. Aluminum frames cost the least. They’re sturdy, light and maintenance-free, but offer poor insulation. Vinyl frames are somewhat expensive and offer good insulation. Composite frames made with wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They’re also aesthetically pleasing and provide decent insulation for your home.

What Services do Window Installers Offer?

In general, there are two kinds of window replacement services companies provide: full-frame and pocket installations.

A full-frame installation is a total window replacement. It involves taking out the old window, the sill, and the exterior and interior trim. It can also involve extra materials, like insulation and drip edges, which increase the overall 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. Pocket installations are on the simpler end and won’t carry as large a bill, as they involve merely replacing the window within its existing frame. But if the frame has any damage or rot, you may have to get a full-frame installation instead.

If you’re still debating which type of installation you should get, you can talk to your provider and get their advice. The choice mostly is influenced by the age of your window frames and if there’s any damage.
