How Installing Energy-Efficient Windows in East Flat Rock Saves You Money
By upgrading to energy-efficient windows, you can enjoy several benefits, such as:
- Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes tend to have windows that are outdated, leaky or maybe even damaged in some way. Upgrading your windows could help increase the value of your property if you decide to sell.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
- Save money on energy bills: Since energy-efficient windows reduce the amount of energy used to heat or cool your home, they can help you save about $312 annually on your energy bills in East Flat Rock.
- Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% after you install Energy Star certified windows. In East Flat Rock, that's about 345 pounds per year on average.
Estimated Cost of Window Replacement in East Flat Rock
Windows come in various shapes and sizes, so costs and services will vary remarkably. Here are the average costs and services that you can find from window installation companies.
How Much Do New Windows Cost?
Generally, homeowners in East Flat Rock can expect that most replacement window installations will range from $250 to $1,200, with the average cost at about $600. How much it will cost is based on several factors, such as type, number of windows, the location of your home, size, material and more.
Whether or not you want energy-efficient windows is another factor that will affect the cost. These will typically cost more than other windows, but on the other hand, you can save about $312 a year on your energy bills in East Flat Rock.
Costs will also vary depending on the material of your frame. Aluminum frames are the least expensive. They're sturdy, light and maintenance-free, but offer poor insulation. Vinyl frames are a bit more expensive and offer good insulation. Composite frames made from wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They're also aesthetically pleasing and offer decent insulation for your home.
What Services do Window Installers Offer?
There are generally two kinds of window installation 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 also involves other materials, like insulation and drip edges, which raise the overall cost of the project. Also worth noting: you may have to touch up the paint around the window after a full-frame installation. Pocket installations (or retrofits) involve installing a new window within its existing frame, which makes pocket installations more simple and affordable. But, if the frame has any damage or rot, you should opt for a full-frame installation instead.
Your window installer can help you choose which type of installation you should get.

How We Choose the Best Window Installers in East Flat Rock
The EcoWatch Reviews team differs from most reviewers because we assess these companies through a sustainability lens. Along with energy efficiency, we reviewed window companies all across the state and ranked them based on the following methodology:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installers that serve East Flat Rock so you can find the right window installation company near you.
Work Quality
When choosing new windows, the quality and range of services can often play just as important of a role in overall efficiency and performance as the type of window you opt for. We do rate window installers higher if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
Customer feedback is another super important review factor. If the majority of customers don't have nice feedback 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 want to keep costs low when possible. When analyzing providers' prices, we awarded higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed, windows are a substantial investment, so you'll want to make sure that investment is well protected. Window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have been in the industry for quite some time. Window installation companies that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.
East Flat Rock, NC Window Replacement FAQs
How much should a window install cost?
The average cost to install a single window can range from $450 to $650. There are several factors that influence the price, which include local labor costs, the number of windows, the materials used in designing the windows, your property's location, styles and sizes of windows and how energy-efficient the windows are.
Which type of window should I get?
Generally, double-pane windows will be more efficient than single-pane windows and windows that do not 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 — this means they're certified energy-efficient by the U.S. Department of Energy.
Can I install my own windows?
If you're handy and have experience with similar home improvement projects, it's possible to install your own windows. But if you don't have the time or know-how, we recommend getting a professional to do it for you.
How often do you need to replace your windows?
Windows usually last about 20 to 30 years, but anytime you see damage on your windows, it's a good time to have an expert take a look at them to determine if they need any repairs or replacements.
Should I replace all my windows at the same time?
If your windows are more than 20 years old, it's most likely time to replace all of them. At that point, they are usually less efficient, draftier and/or more damaged than new windows. Replacing your windows all at the same time will involve less paperwork and less time.
