Calculate how much you can expect to pay for window installation and replacement in South Fulton, GA using our customized window cost calculator.

How Installing Energy-Efficient Windows in South Fulton Saves You Money
By upgrading to energy-efficient windows, you can enjoy several benefits, including:
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out damaging UV rays, reducing fading of your furniture, carpet and other valuables.
- Decrease your carbon footprint: By using less energy after switching to energy-efficient windows, you’ll also be decreasing your carbon dioxide emissions by about 12%, according to Energy Star.
- Save money on energy bills: Because energy-efficient windows lower the amount of energy used to heat or cool your home, the switch can help you save around $362 annually on your energy bills in South Fulton.
- Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes tend to have windows that are outdated, drafty or potentially even damaged in some way. Updating your windows could help raise the value of your property if you decide to sell.
Estimated Cost of Window Replacement in South Fulton
Let’s take a look at the cost of window replacement and the kinds of services offered by installers.
How Much Do New Windows Cost?
According to our research, the national average cost of replacing a single window is about $600. However, window replacement costs can range from $200 to $1,200 for each window. How much it will cost depends on several factors, such as size, number of windows, the location of your home, material, type and more.
With windows, efficiency is the most important factor for many homeowners. Efficient windows may cost more off the bat, but by increasing the efficiency of your home — especially if you live in a hot climate — they can provide decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save South Fulton homeowners $362+ a year after replacing single-pane windows.
Asking for free quotes from several companies is the best way to find out which one is right for you.
What Services do Window Installers Offer?
The first thing to ask yourself when planning a window installation is: Do you need a full-frame installation or a pocket installation?
Full-frame installations require replacing the whole window — the sill, frame, trim and all. These are most common when you want to change the style of your window or when it has a great amount of deterioration. Full-frame installations are more time-consuming and will increase overall costs. A pocket installation involves replacing a window within the frame that’s already there. So, instead of taking out the whole window and rebuilding it, the window installer will just slide the replacement window (also called a retrofit or insert window) into the frame.
Your window installation company can recommend the best type for your project. In South Fulton, the decision will mostly be influenced by how much damage there is currently and how old your existing frames are.

How We Choose the Best Window Installers in South Fulton
In our search to make your home improvements easier and more eco-friendly in South Fulton, the EcoWatch Reviews team assessed many companies before settling on these. We’ve assessed the top window installation companies in South Fulton primarily based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows have been shown to lower electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
Because this is a guide for South Fulton, we gave more points to companies that serve the city. There are certainly other reputable providers that didn’t make the cut because they wouldn’t be able to serve homeowners in South Fulton.
Work Quality
When selecting new windows, the quality and breadth of services often plays 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
We analyzed trends in recent online reviews to find the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across nearly every category, including professionalism, quality of parts, warranty, quality of installation, cost and more.
Cost
Cheaper windows certainly don’t mean better windows, but we know many of our readers would like 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
As discussed previously, windows are a hefty investment, so you’ll want to be certain that investment is well protected. Window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to South Fulton’s climate, homeowners will want to mitigate water damage, low efficiency and rot. We factored in local experience to reflect the ability of South Fulton window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
South Fulton, GA Window Replacement FAQs
How much should a window install cost?
The average cost to install one window ranges between $450 and $650. There are many factors that affect how much it costs, such as your property’s location, how energy-efficient the windows are, the number of windows, styles and sizes of windows, the materials used in designing the windows and local labor costs.
What are the most common types of replacement windows?
There are several different kinds of windows you can get for your house, including casement windows, bay windows, picture windows, transom windows, slider windows, double-hung and single-hung windows and awning windows.
What services do window installation companies offer?
Window installation companies will do the entire process — from replacing your old windows with new ones to cleaning up after the installation. In addition, some companies offer window manufacturing, customization and repairs.
When is the best time of year to replace windows?
Replacement windows can be installed at any time, but autumn might be the best season. No matter when you install them, the contractors will take steps to ensure that too much hot or cold air doesn’t get into your home, so the temperature outside doesn’t necessarily matter that much. Most importantly, the weather should be dry.
When is it time to replace your windows?
Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, then they probably need to be replaced. Other than that, if your windows have damage anywhere on them, or they have become difficult to operate, they may be in need of replacement.
