How Installing Energy-Efficient Windows in Cornelia Saves You Money
By upgrading to energy-efficient windows, you can benefit in several ways, such as:
- Save money on electricity bills: After you upgrade to energy-efficient windows, you can see a reduction in your bills by about 12% since you'll need less energy to heat or cool your home.
- 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 Older homes tend to have windows that are outdated, drafty or maybe even damaged in some way. Updating your windows could help raise the value of your home if you decide to sell.
- Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% after you install Energy Star certified windows. In Cornelia, that's about 476 pounds per year on average.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in Cornelia
When looking into window installation, each company offers different services and prices. Let's go over some typical costs and services.
How Much Do New Windows Cost?
Typically, homeowners in Cornelia can expect that most window installations will range from $250 to $1,200, with the most common installations sitting at around $600. This is because window installations depend on a variety of factors specific to your home, including the size, material and number of windows you need to replace, as well as the location of your property.
It's also worth noting that energy-efficient windows will cost more upfront, but Energy Star predicts that upgrading the windows on your Cornelia home translates to an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. The amount of money you'll save by upgrading to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
Costs will also vary based on the material of your frame. Aluminum frames are the least expensive. They're sturdy, light and maintenance-free, but provide poor insulation. Vinyl frames are somewhat expensive and provide good insulation. Composite frames made with wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They're also aesthetically pleasing and provide decent insulation for your home.
What Services do Window Installers Offer?
The first step when considering a window replacement is to clarify whether you should get a full-frame or pocket installation.
A full-frame installation replaces the complete window, such as the sill, frame, trim and the window panes. Because this kind of installation is more involved, it will be more expensive than a pocket installation. A pocket installation entails installing a new window within the existing frame. This means instead of removing the whole window and rebuilding it, the installer will just slide the replacement window (also called a retrofit or insert window) into the frame.
Your window replacement company should be able to help you choose what's best for your needs. In Cornelia, the decision will mostly be based on the age of your windows and if there's any moisture damage. Wood can decay if not properly maintained over the years, so it's a good idea to have a professional check on your frames and window sills.

How We Choose the Best Window Installers in Cornelia
In our search to find the most reliable, eco-friendly window installers in Cornelia, EcoWatch landed on the above companies as the best window installation companies in the city. Along with energy efficiency, we reviewed several window installers in Cornelia and assigned rankings using the following methodology:
Service Area
This one is self-explanatory, but we've chosen to highlight window installation companies that serve Cornelia so you can find a quality window installation company near you.
Work Quality
We're willing to bet that you're not looking for a company to do a shoddy job installing windows. We've vetted each installer included in our guide to make sure its contractors are well-qualified and that the company has gotten plenty of positive customer feedback to vouch for its service.
Customer Reviews
Another self-explanatory yet very important review factor is customer feedback. If the majority of customers don't have good things to say about their service from a certain installer, you won't see it featured on EcoWatch.
Cost
This one is a give-and-take: as with other services, cheap window installation companies may not provide the most quality service. Still, we want to make sure we're highlighting companies that provide a wide range of price and financing options so they're accessible to most homeowners.
Warranty
Protecting your investment in new windows is important. That's why window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to Cornelia's climate, homeowners need to be wary of low efficiency, water damage and rot. We factored in local experience to reflect the ability of Cornelia window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Cornelia, GA Window Replacement FAQs
How much does a window install cost?
The national average cost of installing a single window is about $600 but can range from $200 to $1,200, based on several factors. The price is generally dependent on the size of the window, the location of your property and the type and material of the window. Also, remember that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.
Which kind of window is the best?
Generally, double-pane windows are more efficient than single-pane windows and windows that do not open are more efficient than windows that do. If you want to be sure you'll have the most energy-efficient windows, look for models with the blue Energy Star certification attached to them — they're certified energy-efficient by the U.S. Department of Energy.
What do window installers do?
Window installers go to your house to remove your old windows and replace them with new ones. Some companies install products manufactured by other companies, whereas others install their own windows. The installer will also clean up after the installation is done.
How long does it take to install windows?
Since the average installation time is 30 minutes per window, around 16 windows can be installed in an 8-hour work day.
Should I replace my windows all at the same time?
If you're upgrading your windows because of energy-efficiency, replacing all of your windows at once is the only way to see a noticeable difference. On the other hand, if you have only one or two windows that are broken or drafty, you can replace just those.
