How Installing Energy-Efficient Windows in Kennesaw Saves You Money
Upgrading to energy-efficient windows can help improve the comfort of your home and help you save on electricity bills. Here are more details about how upgrading your windows could benefit you:
- Save on energy bills: Because energy-efficient windows reduce the amount of energy needed to heat or cool your home, they can help you save about $383 annually on your energy bills in Kennesaw.
- Reduce your carbon footprint: In Kennesaw, you can cut your indirect greenhouse gas emissions by about 476 pounds per year after you upgrade to energy-efficient windows.
- 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 Older homes tend to have windows that are outdated, drafty or maybe even damaged in some way. Updating your windows could help increase the value of your home if you decide to sell.
- 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.
Estimated Cost of Window Replacement in Kennesaw
Windows come in varying purposes, styles and shapes, so costs and services will differ remarkably depending on several factors. Below, we go over the average cost and services that you can get from window installation companies.
How Much Do New Windows Cost?
The average cost to install a single window is about $600 but can range anywhere from $200 to $1,200. How much it will cost is based on several factors, like type, the location of your home, number of windows, size, material and more.
It's also worth keeping in mind that energy-efficient windows will typically cost more initially, but Energy Star predicts that upgrading the windows on your Kennesaw home translates to an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. The amount of money you'll save by installing energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
We advise requesting free quotes from several window installation companies to find the right windows and the company that works best for you.
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. Because this kind of installation is more involved, it will be more expensive than a pocket installation. A pocket installation involves replacing a window without removing the complete frame, which is generally cheaper than a full-frame installation.
If you're not sure which kind of window installation service you need, your installer can assist you. In general, the decision is based on factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Kennesaw
In our hunt to find the most reliable, eco-friendly window installers in Kennesaw, the EcoWatch Reviews team landed on the above companies as the top window installation companies in the city. We have decided to review the best window installers in Kennesaw primarily based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows have been shown to reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
Since this is a guide for Kennesaw, we only included companies that serve the city. There are certainly reputable providers that didn't make our list because of the low odds that they would serve the average homeowner in Kennesaw.
Work Quality
We're certain that you're looking for professionals who do a great job installing windows. We've vetted each company included in our guide to ensure its technicians are well-qualified and that the company has received lots of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed patterns in recent customer feedback to determine the companies with the most 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 most other categories, including quality of parts, warranty, quality of installation, cost, professionalism and more.
Cost
This one is a give-and-take: similar to most services, cheap window companies won't always provide the most quality service. Still, we want to ensure 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 to many homeowners. That's why window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to Kennesaw's climate, homeowners will want to mitigate low efficiency, water damage and rot. We factored in local experience to reflect the ability of Kennesaw window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Kennesaw, GA Window Replacement FAQs
How much does a window install cost?
The typical cost of replacing a single window ranges between $450 and $650. There are several factors that influence how much it costs, such as the number of windows, your property's location, styles and sizes of windows, the materials used in designing the windows, how energy-efficient the windows are and local labor costs.
What type of window is the best for energy efficiency?
Generally, double-pane windows are more efficient than single-pane windows and windows that don't open will be more efficient than windows that do. To be sure you'll have the most energy-efficient windows, look for models that have the blue Energy Star certification — they're certified energy-efficient by the U.S. Department of Energy.
Can I replace my own windows?
Although it is possible to install your own windows, doing so requires a lot of time and experience with home improvement projects. Hiring a professional can help guarantee that the job is done properly and that you can avoid spending the time and effort of doing it yourself.
What time of year is a good time to replace my windows?
Although you can install windows any time of year, warmer weather is generally better for replacing windows. In addition, the weather should be dry, because rain can make the installation more difficult.
How often do you need to replace windows?
Windows usually have a lifespan of around 20 to 30 years, but anytime you see damage on your windows, it's a good idea to have them looked at by an expert to determine if they are in need of a repair or replacement.
