How Installing Energy-Efficient Windows in Snellville Saves You Money
By switching to energy-efficient windows, you and your family can take advantage of several benefits, including:
- Save money on electricity bills: Once you switch to energy-efficient windows, you can expect a reduction in your bills by about 12% because you’ll use less energy to heat or cool your home.
- Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
- Decrease your carbon footprint: By using less energy once upgrading to Energy Star certified windows, you’ll also be decreasing your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes usually have windows that are outdated, drafty or potentially even damaged in some way. Upgrading your windows could help raise the value of your property if you decide to sell.
Estimated Cost of Window Replacement in Snellville
When looking into window installation, each company offers different services and prices. Let’s look at some average costs and services.
How Much Do New Windows Cost?
The typical cost to install a single window is about $600 but can range from $200 to $1,200. But costs differ remarkably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also provide door installations and replacements, which carry a higher price tag.
Whether or not you opt for energy-efficient windows is another factor that will influence the cost. These will usually cost more than other windows, but on the other hand, you can save about $343 a year on your energy bills in Snellville.
Another factor that affects the total cost is the material of the frame you choose. Aluminum frames are usually the least expensive and are sturdy and relatively maintenance-free, but they provide poor insulation. On the other hand, wood frames cost the most, as they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.
What Services do Window Installers Offer?
There are generally two kinds of window installation services: full-frame and pocket installations.
A full-frame installation replaces the entire window, such as the sill, frame, trim and the window panes. As this type of installation is more involved, it will cost more than a pocket installation. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are on the simpler end and won’t carry as large a bill, but you can’t do this type of installment if you have any pre-existing rot or water damage.
If you’re still debating which type of installation you need, you can ask your installer and get their recommendation. The decision mostly is influenced by the age of your window frames and if there’s any damage.

How We Choose the Best Window Installers in Snellville
In our search to find the most reliable, eco-friendly window installers in Snellville, the EcoWatch team examined many companies before deciding on these. We have reviewed the top window replacement companies in Snellville primarily based on energy efficiency, as it’s the most sustainable option and the best one for homeowners. Energy-efficient windows can reduce your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
This one is pretty self-explanatory, but we’ve chosen to highlight window installers that serve a wide variety of states and cities so you can find the best window installation company near you.
Work Quality
When picking new windows, the quality and range of services often plays just as important of a role in insulation and performance as the brand of window you opt for. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
We analyzed patterns in recent online reviews to find the companies with the most consistent customer satisfaction. Customer satisfaction might be the most important factor, as it reflects the quality of services across nearly every category, including warranty, quality of installation, cost, quality of parts, professionalism and more.
Cost
This one is a give-and-take: as with other services, cheap window installation companies may not provide the highest quality service. Still, we want to ensure we’re highlighting companies that offer a wide range of price and financing options so they’re accessible to most homeowners.
Warranty
Protecting your investment in new windows is important. For that reason, window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have been in the industry for a while. Window installation companies that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Snellville, GA Window Replacement FAQs
What is the average cost to install new windows in a home?
The typical cost of installing one window ranges from $450 to $650. There are several factors that influence the cost, including your property’s location, the number of windows, local labor costs, how energy-efficient the windows are, the materials used in designing the windows and styles and sizes of windows.
Which kind of window is the best?
Generally, double-pane windows will be more efficient than single-pane windows and windows that don’t open are more efficient than windows that do. To be sure you’ll have the most energy-efficient windows, look for models with the blue Energy Star certification — this means they’re certified energy-efficient by the U.S. Department of Energy.
When should I use a window installation company?
Unless you have experience with home improvement projects and have the time to replace your own windows, we recommend hiring a professional installer. The window installation process is complicated and can take anywhere from four to six hours for one window. Although it’s tempting to try to save money by doing it yourself, hiring a professional is a faster, more efficient and safer option.
What time of year is the best time to replace my windows?
While you can install windows any time of year, warmer weather is generally better for replacing windows. In addition, it shouldn’t be raining, since rain can make the installation more difficult.
Should I replace my windows all at once?
If you’re upgrading your windows because of energy-efficiency, replacing all of the windows at once is the only way to gain that benefit. On the other hand, if you have only a few windows that are damaged or drafty, you can replace just those.
