How Installing Energy-Efficient Windows in Clemmons Saves You Money
When you switch to energy-efficient windows, you may see several benefits, such as:
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out damaging UV rays, reducing fading of your furniture, carpet and other valuables.
- Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Upgrading your windows can make your home more comfortable and also help raise the value of your property if you decide to sell.
- Save on power bills: Upgrading to energy-efficient windows lowers your energy bills by about 12% since you use less energy.
- Reduce your carbon footprint: In Clemmons, you can lower your indirect greenhouse gas emissions by about 345 pounds per year after you switch to energy-efficient windows.
Estimated Cost of Window Replacement in Clemmons
Let’s take a look at the cost of replacing your windows and the kinds of services you may need for your home.
How Much Do New Windows Cost?
The average cost to install one window is about $600 but can range from $200 to $1,200. This is because the cost of window installations are based on a variety of factors specific to your home, like the size, material and number of windows you need to install, as well as where your property is located.
Keep in mind that energy-efficient windows may cost more, but Energy Star estimates the upgrade will save you between $101 and $583 a year when you install single-pane windows and between $27 and $197 a year when replacing double-pane, clear glass windows. These savings vary based on your local climate, energy rates and individual home characteristics.
How much your window installation costs will also vary depending on the kind of window material you choose for the frames. Wood windows are usually the most expensive, though it depends on whether they are completely 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?
In regard to window replacements, in general there are two kinds that your provider will offer: full-frame and pocket installations.
A full-frame installation is a replacement of the total window. It involves taking out the old window, the windowsill, and the exterior and interior trim. It also involves other materials, like insulation and drip edges, which increase the total cost of the project. Also worth noting: you may have to touch up the paint surrounding the window after a full-frame installation. A pocket installation entails replacing a window within the existing frame, which tends to be less expensive than a full-frame installation.
If you’re still debating which type of installation you should get, you can talk to your installer and get their advice. The choice mostly depends on how old the frames are and if there’s any damage present.

How We Choose the Best Window Installers in Clemmons
EcoWatch is different from most reviewers since we assess these companies through a sustainability lens. We have evaluated the top window installation companies in Clemmons mostly based on their energy efficient offerings, as it’s the most sustainable option and the best one for homeowners. Energy-efficient windows can cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
This one is pretty self-explanatory, but we’ve chosen to highlight window installers that serve Clemmons so you can find a quality window installation company near you.
Work Quality
When selecting new windows, the quality and variety of services often plays just as important of a role in overall efficiency and performance as the brand of window you get. We do give window installers more points if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
Another self-explanatory yet very important review factor is customer feedback. If most customers don’t have nice feedback about their service from a certain installer, it won’t be featured on EcoWatch.
Cost
This one is a give-and-take: similar to most services, cheap window installers are not going to provide the highest quality service. On the other hand, we want to ensure we’re highlighting companies that provide a variety of price and financing options so they’re accessible to most homeowners.
Warranty
Protecting your investment in new windows is important. For that reason, window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of Clemmons’s climate, homeowners will want to mitigate water damage, rot and low efficiency. We factored in local experience to reflect the ability of Clemmons window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
