How Installing Energy-Efficient Windows in Decatur Saves You Money

Energy-efficient windows can offer benefits in several ways. Here are a few reasons you may want to consider making the switch:

  • Save money on power bills: Because energy-efficient windows decrease how much energy you need to heat or cool your home, they can help you save around $362 annually on your energy bills in Decatur.
  • Reduce your carbon footprint: Because energy-efficient windows improve the insulation in your home, you can lower your indirect greenhouse gas emissions by about 12%, according to Energy Star.
  • Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
  • Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Updating your windows can improve the insulation in your home and also help increase the value of your house if you decide to sell.

Estimated Cost of Window Replacement in Decatur

Each window installer offers various services and has varying costs based on several factors.

How Much Do New Windows Cost?

On average, Decatur homeowners can anticipate their window replacements to range from $250 to $1,200. The most common installations sit at approximately $600. These numbers vary based on the specifics of your installation, such as size, material, the location of your home, number of windows, type and more.

With windows, efficiency is one of the most important factors for most homeowners. Efficient windows may cost more upfront, but by increasing the efficiency of your home — especially if you live in a hot climate — they can give you decades of energy savings. According to Energy Star, buying certified energy-efficient windows can save Decatur homeowners $362+ per year after replacing single-pane windows.

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 offer 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 offer decent insulation for your home.

What Services do Window Installers Offer?

The first thing to ask yourself when planning to replace your windows is: Should you get a full-frame installation or a pocket installation?

Full-frame installations involve replacing the full window — the sill, frame, trim and all. These are most common when you want to change the style of your window or when it has significant deterioration. Full-frame installations are more time-consuming and will increase overall costs. Pocket installations (or retrofits) entail installing a new window within its existing frame, which makes pocket installations more simple and affordable. However, if the frame has any damage or rot, you will most likely need a full-frame installation instead.

Your window installer should be able to help you choose which type of installation you should get.

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 team evaluated many companies before landing on these. We have evaluated the best window replacement companies in Decatur mainly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows have been shown to lower electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

This one is pretty self-explanatory, but we’ve chosen to highlight window installation companies 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 variety of services often plays just as important of a role in insulation and performance as the brand of window you get. 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 determine the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction may be the factor we place the most value on, as it indicates 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: similar to other services, cheap window companies may not provide the most quality service. On the other hand, we want to ensure we’re highlighting companies that provide a 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 offer lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Due to Decatur’s climate, homeowners need to be wary of rot, low efficiency and water damage. 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 average cost to install windows?

The national average cost of replacing a single window is about $600 but can range from $200 to $1,200, based on a few different factors. The price is generally dependent on the size of the window, the location of your property and the type and material of the window. Also, bear in mind that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.

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 — this means they’re certified energy-efficient by the U.S. Department of Energy.

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 sold by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation is complete.

Should I replace all my windows at the same time?

If your windows are more than 20 years old, you most likely need to replace all of them. At that point, they are typically less efficient, draftier and/or more damaged than new windows. Replacing your windows all at once will involve less paperwork and less stress.

How long does it usually take to install windows?

Since the average installation time is 30 minutes per window, about 16 windows can be installed in an 8-hour work day.
