Why you can trust EcoWatch
Although renewable energy sources like wind and solar are important when it comes to decreasing your carbon footprint, improving your house’s energy efficiency can also have a considerable impact on home energy conservation. When it’s the middle of summer, your outdated and drafty windows could be making your home more difficult to cool and costing you more in power bills.
That’s also bad news for the environment, as the extra energy used by old windows increases your carbon footprint.
Efficient windows are of particular importance in Decatur, where summers are long and hot. According to Energy Star, making the switch to energy-efficient windows can save the average homeowner up to $390 each year.

How Installing Energy-Efficient Windows in Decatur Saves You Money
There are quite a few perks of upgrading to energy-efficient windows. Some reasons you may want to consider making the switch include the following:
- Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its real estate value, especially if you have an older home.
- Decrease your carbon footprint: By using less energy after switching to Energy Star certified windows, you’ll also be decreasing your carbon dioxide emissions by about 12%, according to Energy Star.
- Save money on energy bills: Installing energy-efficient windows lowers your energy bills by about 12% because you use less energy.
- Protect your valuables: Many Energy Star certified 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
When considering window installation, each company provides different services and prices. Let’s take a look at some average costs and services.
How Much Do New Windows Cost?
According to our market research, the typical cost of installing a single window is about $600. However, window replacement costs can range from $200 to $1,200 per window. These figures vary depending on the specifics of your installation, like number of windows, material, size, type, the location of your home and more.
Whether or not you want to install energy-efficient windows is another factor that will affect the cost. These will almost always cost more than other windows, but on the other hand, you can save about $390 a year on your energy bills in Decatur.
Costs will also vary depending on the material of your frame. Aluminum frames have the lowest price. 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 using wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They’re also aesthetically pleasing and provide decent insulation for your home.
What Services do Window Installers Offer?
The first question to ask yourself when planning on installing new windows is: Should you get a full-frame installation or a pocket installation?
Full-frame installations are usually recommended when you want a new style or your window has significant rot or deterioration. With this service, your professionals will replace the complete window, including the sill, trim and frame. Pocket installations are simpler and won’t cost as much, as they involve merely replacing the window within its existing frame. But if the frame has any damage or rot, you should opt for a full-frame installation instead.
If you’re hiring a reputable window installation company, your company will be able to advise you on the best type for your project. In Decatur, the choice will mostly depend on the efficiency of your home and how old your existing frames are.

How We Choose the Best Window Installers in Decatur
In our search to make your home improvements easier and more eco-friendly in Decatur, the EcoWatch Reviews team examined many companies before settling on these. We have evaluated the top window installation companies in Decatur primarily based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows have been shown to reduce your energy 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 Decatur, we paid more attention to companies that cover the city. There are certainly reputable providers that didn’t make the cut because of the low odds that they would serve the average homeowner in Decatur.
Work Quality
When picking new windows, the quality and variety of services can often play just as important of a role in overall efficiency and performance as the brand of window you choose. We do give window installers more points if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
We analyzed trends 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 nearly every category, including professionalism, warranty, cost, quality of installation, quality of parts and more.
Cost
Cheaper windows don’t necessarily mean better windows, but we know many of our readers want to keep costs low when possible. When analyzing the prices of providers, we gave higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of Decatur’s climate, homeowners need to be wary of water damage, low efficiency and rot. We factored in local experience to reflect the ability of Decatur window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Decatur, AL Window Replacement FAQs
What is the average cost to install windows in a home?
The average cost to install a single window ranges from $450 to $650. There are a variety of factors that influence the cost, such as the number of windows, the materials used in designing the windows, styles and sizes of windows, your property’s location, how energy-efficient the windows are and local labor costs.
What type of window is the most energy-efficient?
Generally, double-pane windows will be more efficient than single-pane windows and windows that do not open are more efficient than windows that do. If you want to be sure you’ll get the most energy-efficient windows, look for models that have the blue Energy Star certification attached to them — this means they’re certified energy-efficient by the U.S. Department of Energy.
Can you replace your own windows?
If you’re handy and know how to replace a window, you may be able to install your own windows. However, if you don’t have the time or know-how, we don’t recommend trying it.
Should I replace all my windows at the same time?
If you’re upgrading your windows because of energy-efficiency, replacing all the windows at the same time is the only way to see a noticeable difference. However, if you have only one or two windows that are broken or leaky, you can replace just those.
