How Installing Energy-Efficient Windows in Clemmons Saves You Money
Switching to energy-efficient windows can help improve the comfort of your home and help you save on energy bills. Here's more information on how switching out your windows could help you:
- Decrease your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% when you install Energy Star certified windows. In Clemmons, that's about 345 pounds per year on average.
- Better temperature control in your home: When you live in a city like Clemmons where the summers can get very hot, you usually need to rely on your air conditioner to keep your home cool. Energy-efficient windows can lower how hard your AC needs to work to cool your home.
- Better temperature control in your home: Energy-efficient windows can reduce how hard your heating system needs to work to heat your home.
- Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Updating your windows can make your home more comfortable and also help increase the value of your home if you decide to sell.
Estimated Cost of Window Replacement in Clemmons
Windows come in varying shapes and sizes, so costs and services will vary considerably. Here are the typical costs and the primary services that you can find from window installers.
How Much Do New Windows Cost?
According to our research, the typical cost to install a single window is around $600. However, window replacement costs can range from $200 to $1,200 for each window. These figures vary depending on specific characteristics of your installation, such as material, type, the location of your home, number of windows, size and more.
Keep in mind that energy-efficient windows may cost more upfront, but Energy Star predicts the upgrade will save you between $101 and $583 per year when you install single-pane windows and between $27 and $197 per year when you install double-pane, clear glass windows. Your savings will vary depending on your local climate, energy rates and individual home characteristics.
Requesting free quotes from multiple installers is the best way to find out which one will work best for your budget.
What Services do Window Installers Offer?
There are typically two types of window replacement services: 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 additional 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 (or retrofits) entail replacing a window within its existing frame, which makes pocket installations more simple and affordable. But, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.
Your window installation company can recommend the best type for your project. In Clemmons, the choice will mostly be based on how much damage there is currently and how old your existing frames are.

How We Choose the Best Window Installers in Clemmons
In our hunt to make your home improvements easier and more eco-friendly in Clemmons, the EcoWatch Reviews team evaluated dozens of companies before deciding on these. Along with energy efficiency, we analyzed several window installers in Clemmons and assigned rankings based on the following methodology:
Service Area
Since this is a guide for Clemmons, we paid more attention to companies that provide services to the city. There are certainly other reputable providers that didn't make the cut because of the low odds that they would serve the average homeowner in Clemmons.
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 make sure its contractors are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.
Customer Reviews
Customer feedback is another super important review factor. If the majority of customers don't have positive things to say about their experience with a certain window installation company, you won't see it featured on EcoWatch.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers try to keep costs as low as possible. When analyzing the prices of providers, we awarded higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
Protecting your investment in new windows is important to many homeowners. That's why window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to Clemmons' climate, homeowners will want to mitigate low efficiency, water damage and rot. We factored in local experience to reflect the ability of Clemmons window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Clemmons, NC Window Replacement FAQs
How much should a window install cost?
The national average cost of replacing a single window is around $600 but can range between $200 and $1,200, depending on a few different factors. The price is often dependent on 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 a decent amount of money a year in energy bills.
Which type of window is the best?
Generally, double-pane windows are more efficient than single-pane windows and windows that don't open will be more efficient than windows that do. To be sure you're getting the most energy-efficient windows, look for models with the blue Energy Star certification attached to them — that means they're certified energy-efficient by the U.S. Department of Energy.
What do window installers do?
Window installation professionals will do the entire process — from replacing your old windows with brand new ones to cleaning up after the installation. Additionally, a lot of companies offer window manufacturing, customization and repairs.
Should I replace all my windows at once?
If your windows are greater than 20 years old, it's probably time to replace all of them. By that point, they are typically less efficient, leakier and/or more damaged than new windows. Replacing your windows all at the same time will involve less paperwork and less time.
