How Installing Energy-Efficient Windows in Athens Saves You Money
There are several benefits of switching to energy-efficient windows. A few reasons you may want to consider making the change are the following:
- Reduce your carbon footprint: By using less energy after upgrading to energy-efficient windows, you’ll also be lowering your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Save money on power bills: Installing energy-efficient windows reduces your energy bills by about 12% since you need less energy.
- Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
- 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 Older homes tend to have windows that are outdated, leaky or maybe even damaged in some way.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 Athens
Windows come in different shapes and sizes, so costs and services will differ remarkably. Here are the typical costs and the primary services that you can find from the average window installation company.
How Much Do New Windows Cost?
Generally, Athens homeowners can expect their replacement window installations to range from $250 to $1,200. The average cost sits at around $600. This is because of the fact that the cost of window installations are based on a variety of factors specific to your home, including the size, material and number of windows you need to install, as well as the location of your property.
It’s important to remember that windows with higher efficiency may cost more initially but can save you hundreds of dollars via returns on your energy bills. Investing in Energy Star certified windows can save Athens homeowners $305+ a year when replacing single-pane windows.
Costs will also vary depending on the material you want for your window frames. Aluminum frames cost the least. They’re sturdy, light and maintenance-free, but offer poor insulation. Vinyl frames are a bit more expensive and offer good insulation. Composite frames made using 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 offer decent insulation for your home.
What Services do Window Installers Offer?
The first step when considering a replacement is to clarify whether you should get a full-frame or pocket installation.
Full-frame installations are necessary when you want a new style or your window has significant rot. With this service, your installers will replace the total window, including the frame, sill and trim. A pocket installation means replacing a window within the existing frame, which is generally less expensive than a full-frame installation.
If you’re still debating which type of installation you need, you can talk to your provider and get their advice. The decision mostly depends on the age of your window frames and if there’s any damage.

How We Choose the Best Window Installers in Athens
In our hunt to find the most reliable, eco-friendly window installers in Athens, the EcoWatch Reviews team chose the above companies as the best window installation companies in the city. Along with energy efficiency, we reviewed each installer and assigned rankings based on the following methodology:
Service Area
Since this is a guide for Athens, we only included companies that provide services to the city. There are other reputable providers that didn’t make the list because they wouldn’t be able to serve homeowners in Athens.
Work Quality
We’re certain that you’re looking for a company to do a great job installing windows. We’ve vetted each company featured in our guide to ensure its technicians are well-qualified and that the company has gotten a lot of positive customer feedback to vouch for its service.
Customer Reviews
Customer feedback is another super important review factor. If the majority of customers don’t have good feedback about their service from a certain installer, you won’t see it featured on EcoWatch.
Cost
This one is a give-and-take: similar to most services, cheap window companies may not provide the highest quality service. On the other hand, we want to ensure we’re highlighting companies that provide a variety of price and financing options so they’re accessible to most homeowners.
Warranty
Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of Athens’s climate, homeowners will want to mitigate low efficiency, rot and water damage. We factored in local experience to reflect the ability of Athens window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Athens, TN Window Replacement FAQs
How much should a window install cost?
The average cost to replace one window can range between $450 and $650. There are many factors that affect the price, such as the number of windows, local labor costs, how energy-efficient the windows are, the materials used in designing the windows, styles and sizes of windows and your property’s location.
What type of window is the most energy-efficient?
A window’s energy efficiency depends on several factors, such as the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are typically the most energy-efficient since they are certified by the U.S. Department of Energy.
Do you really have to 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. The window installation process is complex and can take anywhere from four to six hours for a single window. Although it’s tempting to try to save money by doing it yourself, hiring a professional is a faster, more efficient and much safer option.
Should I replace all my windows at the same time?
If your windows are greater than 20 years old, it’s most likely time to replace all of them. At that point, they are typically less efficient, leakier and/or more damaged than new windows. Doing your windows all at once will involve less paperwork and less stress.
How long does it usually take to install windows?
Each window takes about 30 minutes to install depending on the type of window. However, the window installation can take two days or more if you need to have a lot of windows installed.
