How Installing Energy-Efficient Windows in Decatur Saves You Money
Upgrading to energy-efficient windows can improve the comfort of your home and help you save on electricity bills. Here's more information on how upgrading your windows could help you:
- Save money on energy bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of household energy use. Replacing your windows with energy-efficient models can help decrease that number, therefore saving you about 12% more on your bills.
- Reduce your carbon footprint: In Decatur, you can lower your indirect greenhouse gas emissions by about 476 pounds per year once you install energy-efficient windows.
- Protect your investment: When you have an older home, your windows could also be outdated or drafty. Keeping your windows up to date is an important part of maintaining your property and its real estate value.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in Decatur
Each window installation company provides various services and has different price points depending on a few factors.
How Much Do New Windows Cost?
On average, homeowners in Decatur can anticipate that most replacement window installations will range from $250 to $1,200, with the most common installations sitting at around $600. Costs will differ significantly based on the number of windows you need, the current condition of your home, the quality of your products and your location. A lot of window companies also offer door installations and other add-ons like coating, shutters, baths and more. These extra services will increase overall project costs.
Whether or not you choose energy-efficient windows is another factor that will determine the cost. These will usually cost more than other windows, but on the other hand, you can save about $400 a year on your energy bills in Decatur.
Costs will also vary depending on the material you pick for your window frames. Aluminum frames cost the least. They're sturdy, light and easy to maintain, but provide poor insulation. Vinyl frames are a bit more expensive and provide good insulation. Composite frames made with 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 provide decent insulation for your home.
What Services do Window Installers Offer?
In general, there are two types of window replacement services you can get: full-frame and pocket installations.
A full-frame installation replaces the total window, such as the sill, frame, trim and the window panes. Because this kind of installation requires more time and labor, it will be more expensive than a pocket installation. Pocket installations (or retrofits) involve installing a new window within its existing frame, which makes pocket installations less labor-intensive and costly. But, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.
Your window installation company will be able to help you figure out what's best for your needs. In Decatur, the decision will mostly depend on the age of your windows and if there's any damage. Wood can decay if it's not maintained properly over the years, so it's a good idea to have a professional evaluate your frames and window sills.

How We Choose the Best Window Installers in Decatur
In our search to find the most reliable, eco-friendly window installers in Decatur, the EcoWatch Reviews team evaluated many companies before landing on these. Along with energy efficiency, we assessed several window installers in Decatur and assigned rankings using the following methodology:
Service Area
Because this is a guide for Decatur, we gave more points to companies that serve the city. There are certainly other reputable providers that didn't make our list because they wouldn't be able to serve homeowners in Decatur.
Work Quality
We're willing to bet that you're not looking for a company to do a shoddy job installing windows. We've vetted each installer featured in our guide to make sure its technicians are well-qualified and that the company has gotten plenty 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 nice feedback about their service from a certain window installation company, you won't see it featured on EcoWatch.
Cost
This one is a give-and-take: as with other services, cheap window companies won't always provide the most quality service. On the other hand, we want to make sure we're highlighting companies that offer a spectrum of price and financing options so they're accessible to most homeowners.
Warranty
Protecting your investment in new windows is important. That's why window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of Decatur's climate, homeowners will want to mitigate water damage, rot and low efficiency. We factored in local experience to reflect the ability of Decatur window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Decatur, GA Window Replacement FAQs
What is the typical cost to replace windows in a home?
The national average cost of installing one window is around $600 but can range from $200 to $1,200, based on several factors. The price is generally influenced by the location of your property, the type and material of the window and the size of the window. Also, remember that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.
What are the different kinds of windows?
The most common kinds of windows for homes include: picture windows, double-hung and single-hung windows, casement windows, bay windows, awning windows, transom windows and slider windows.
What do window installation companies do?
Window installers travel to your home to remove your old windows and replace them with new ones. Some companies install products made by other companies, whereas others install their own windows. The installer will also clean up after the installation is done.
Should I replace my windows all at once?
If your windows are greater than 20 years old, it's probably time to replace all of them. By that point, they are often less efficient, draftier and/or more damaged than new windows. Doing your windows all at the same time will involve less paperwork and less time.
