How Installing Energy-Efficient Windows in Williston Saves You Money
When you switch to energy-efficient windows, you may see several benefits, including:
- Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent damage from the sun's UV rays to your floors, carpets and furniture.
- Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes usually have windows that are outdated, drafty or potentially even damaged in some way. Updating your windows could help raise the value of your home if you decide to sell.
- Save on energy bills: The Department of Energy estimates that heat gained or lost via windows makes up around 25-30% of energy use in your home. Upgrading to energy-efficient windows can help reduce that amount, which helps you save more on your bills.
- Decrease your carbon footprint: In Williston, you can lower your indirect greenhouse gas emissions by about 162 pounds per year after you switch to energy-efficient windows.
Estimated Cost of Window Replacement in Williston
Each window installer offers varying services and has different prices based on a few factors.
How Much Do New Windows Cost?
The national average cost to install one window is about $600 but can range anywhere from $200 to $1,200. Costs will differ significantly depending on the number of windows you need, the current condition of your home, the quality of your products and your location. A lot of window companies also offer door installations and other add-ons like baths, shutters, coating and more. These extra services will increase your overall project costs.
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 — particularly during the winter — they can give you many years of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Williston homeowners $651+ a year after replacing single-pane windows.
The cost of your window installation will also vary based on the type of material you choose for the frames. Wood windows are usually the most expensive, though it depends on whether they are 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are more efficient.
What Services do Window Installers Offer?
There are typically two kinds of window replacement services: full-frame and pocket installations.
Full-frame installations are necessary when you want to change the style of your windows or your window has significant deterioration. With this service, your professionals will replace the entire window, including the sill, frame and trim. A pocket installation entails replacing a window within the existing frame, which tends to be cheaper than a full-frame installation.
If you’re unsure which window installation service you need, your installer can assist you. Generally, the choice is based on factors like the age and condition of the home, the type of building material, budget and time restrictions.

Williston, VT Window Replacement FAQs
What is the average cost to install windows in a home?
The national average cost to replace one window is around $600 but can range from $200 to $1,200, based on a few different factors. The price is usually influenced by the location of your property, the type and material of the window and the size of the window. Also, remember that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.
Which type of window is the best?
A window’s energy efficiency depends on several factors, including the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are typically the most energy-efficient since they are certified by the U.S. Department of Energy.
Can I replace my own windows?
If you’re handy and have experience with installing a replacement window, you may be able to install your own windows. However, if you don’t have the time or skills, we recommend hiring a professional.
How often should you replace your windows?
Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, then they should probably be replaced. Other than that, if your windows have any damage on them, or they have become difficult to operate, they may be in need of replacement.
