How Installing Energy-Efficient Windows in Franconia 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 switch include the following:
- Save money on energy bills: Installing energy-efficient windows lowers your energy bills by about 12% because you use less energy.
- 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 Older homes usually have windows that are outdated, leaky or potentially even damaged in some way. Updating your windows could help raise the value of your home if you decide to sell.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only insulate your home better, but also filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
- 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.
Estimated Cost of Window Replacement in Franconia
Windows come in various shapes, styles and purposes, so costs and services will differ greatly depending on your project. Below, we go over the average cost and services that you’ll find from window replacement companies.
How Much Do New Windows Cost?
According to our research, the average cost of installing a single window is around $600. However, window replacement costs can range from $200 to $1,200 a window. These figures vary depending on the specifics of your installation, including type, the location of your home, material, size, number of windows and more.
Whether or not you pick energy-efficient windows is another factor that will influence the cost. These will typically cost more than other windows, but on the other hand, you can save about $359 a year on your energy bills in Franconia.
How much your window installation costs will also vary depending on the type of material you choose for the frames. Wood windows are generally 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 shown to be more efficient.
What Services do Window Installers Offer?
The first question to ask yourself when considering a window replacement is: Do you need a full-frame installation or a pocket installation?
A full-frame installation replaces the total window, including the sill, frame, trim and the window panes. As this type of installation requires more time and labor, it will be more expensive than a pocket installation. Pocket installations (also known as retrofits) are when you replace a window while leaving the existing frame. Pocket installations are simpler and will be less expensive, but you can’t do this type of installment if you have any pre-existing rot or water damage.
Your window installation company can recommend the best type for your project. In Franconia, the choice will mostly be influenced by how much damage there is currently and how old your existing frames are.

How We Choose the Best Window Installers in Franconia
In our hunt to make your home improvements easier and more eco-friendly in Franconia, the EcoWatch Reviews team assessed many companies before settling on these. We’ve evaluated the best window installation companies in Franconia mainly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows have been shown to lower energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
Because this is a guide for Franconia, we gave more points to companies that cover the city. There are other reputable providers that didn’t make our list because of the low odds that they would serve the average homeowner in Franconia.
Work Quality
We’re willing to bet that you’re looking for a company to do a great job installing windows. We’ve vetted each company in our guide to ensure its technicians are well-qualified and that the company has received tons of positive customer feedback to vouch for its service.
Customer Reviews
Another self-explanatory yet super important review factor is customer feedback. If most customers don’t have good feedback about their experience with a certain company, it won’t be featured on EcoWatch.
Cost
This one is a give-and-take: similar to other services, cheap window companies are not going to provide the most quality service. Still, we want to make sure we’re highlighting companies that provide a variety of price and financing options so they’re accessible to most homeowners.
Warranty
As discussed, windows are a hefty investment, so you’ll want to be certain that investment is protected. Window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of Franconia’s climate, homeowners need to be wary of rot, water damage and low efficiency. We factored in local experience to reflect the ability of Franconia window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Franconia, VA Window Replacement FAQs
What is the average cost to replace windows?
The average cost to replace a single window can range from $450 to $650. There are a variety of factors that affect how much it costs, including styles and sizes of windows, your property’s location, how energy-efficient the windows are, the materials used in designing the windows, the number of windows and local labor costs.
What type of window is the best for energy efficiency?
Generally, double-pane windows are more efficient than single-pane windows and windows that do not open will be more efficient than windows that do. To be sure you’ll have the most energy-efficient windows, look for models with the blue Energy Star certification — this means they’re certified energy-efficient by the U.S. Department of Energy.
When should I 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 a professional installer. 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 do it yourself to save money, hiring a professional is a faster, more efficient and safer alternative.
What time of year should I replace my windows?
While you can install windows any time of year, warmer weather is generally better for installing replacement windows. In addition, it shouldn’t be raining, because rain can make the installation harder.
How long does window installation generally take?
Since the average installation time is 30 minutes per window, around 16 windows can be installed in an 8-hour work day.
