How Installing Energy-Efficient Windows in Cornelia Saves You Money
By upgrading to energy-efficient windows, you can benefit in several ways, including:
- Protect your valuables from fading: When you upgrade to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less due to their ability to filter out damaging UV rays.
- Save on electricity bills: Since energy-efficient windows decrease the amount of energy used to heat or cool your home, they can help you save around $335 annually on your energy bills in Cornelia.
- More efficient energy use in your household: Because the winters can get very cold in Cornelia, homeowners often rely on their heater during that time. Energy-efficient windows cut back on how much heat is lost through your windows, which makes it easier to keep your home warm.
- Protect your investment: When you have an older home, your windows could also be outdated or damaged. Keeping your windows up to date is an important part of maintaining your property and its value.
Estimated Cost of Window Replacement in Cornelia
Windows come in all 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 Cornelia can expect that most replacement window installations will cost between $250 and $1,200, with the most common installations sitting at around $600. But costs will vary significantly depending on your location, the quality of your products, the number of windows you need and the current condition of your home. Many window companies also offer door installations and other add-ons like shutters, coating, baths and more. Additional services will increase your overall project costs.
Whether or not you opt for energy-efficient windows is another factor that will influence the cost. These will almost always cost more than other windows, but on the other hand, you can save about $335 a year on your energy bills in Cornelia.
Costs will also vary depending on the material of your frame. Aluminum frames cost the least. They're sturdy, light and easy to maintain, 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?
The first question to ask yourself when considering a window replacement is: Should you get a full-frame installation or a pocket installation?
A full-frame installation replaces the full window, such as the windowsill, frame, trim and the window panes. As this kind of installation is more involved, it will cost more than a pocket installation. A pocket installation involves replacing a window without replacing the frame. This means instead of removing the whole unit and rebuilding it, the installer will just put the replacement window (also called a retrofit or insert window) into the frame.
Your window installation company can help you decide which type of installation you should get.

Cornelia, GA Window Replacement FAQs
What is the average cost to replace windows in a home?
The typical cost to install a window can range from $450 to $650. There are many factors that influence the cost, including how energy-efficient the windows are, the materials used in designing the windows, styles and sizes of windows, local labor costs, the number of windows and your property's location.
What are the different types of windows?
There are various types of windows you can get for your house, such as awning windows, slider windows, picture windows, double-hung and single-hung windows, casement windows, bay windows and transom windows.
Do I really have to use a window installation company?
You should use a window installation company whenever you want to replace your windows. Installing windows is a involved process that can be difficult and time-consuming, so it's best left to the professionals.
What time of year should I replace my windows?
Replacement windows can be installed at any time, but autumn might be the best season. Regardless of when you install them, the contractors will take steps to make sure that too much hot or cold air doesn't get into the house, so the temperature outside doesn't necessarily matter that much. What's most important is that the weather should be dry.
