How Installing Energy-Efficient Windows in Dunwoody Saves You Money
There are quite a few benefits of upgrading to energy-efficient windows. Some reasons you may want to consider making the switch include the following:
- Protect your investment: When you have an older home, your windows could also be outdated or drafty. Upgrading and repairing your windows is an important part of maintaining your property and its value.
- Save on electricity bills: According to the Department of Energy, heat gained or lost through windows accounts for around 25-30% of household energy use. Upgrading to energy-efficient models can help decrease that amount, therefore saving you about 12% more on your bills.
- Protect your valuables: The low-emissivity coatings on many energy-efficient windows help reduce damage from the sun's UV rays to your floors, carpets and furniture.
- Decrease your carbon footprint: By using less energy after upgrading to Energy Star certified windows, you'll also be decreasing your indirect greenhouse gas emissions by about 12%, according to Energy Star.
Estimated Cost of Window Replacement in Dunwoody
When researching window installation, each company provides varying services and prices. Let's look at some typical costs and services.
How Much Do New Windows Cost?
Generally, Dunwoody homeowners can anticipate their replacement window installations to range from $250 to $1,200. The most common installations sit at approximately $600. How much it will cost is based on several factors, such as material, size, type, the location of your home, number of windows and more.
Keep in mind that energy-efficient windows may cost more upfront, but Energy Star predicts the upgrade will save you between $101 and $583 a year when replacing single-pane windows and between $27 and $197 a year when replacing double-pane, clear glass windows. Your savings will vary depending on your local climate, energy rates and individual home characteristics.
Another factor that affects the total cost is the material of the frame you select. Aluminum frames are generally the least pricey and are sturdy and light, but they offer poor insulation. On the other hand, wood frames cost the most because they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.
What Services do Window Installers Offer?
There are typically two types of window replacement services: full-frame and pocket installations.
Full-frame installations involve replacing the entire window — the sill, frame, trim and all. These are typically done when you want to change the style of your window or when it has significant damage. Full-frame installations involve more time and labor and will increase overall costs. A pocket installation entails replacing a window within the existing frame, which is usually cheaper than a full-frame installation.
Your window installer should be able to help you choose which type of installation you need.

How We Choose the Best Window Installers in Dunwoody
In our search to find the most reliable, eco-friendly window installers in Dunwoody, the EcoWatch team assessed many companies before deciding on these. Along with energy efficiency, we assessed each installer and ranked them based on the following methodology:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve the Dunwoody area so you can find a quality window installation company near you.
Work Quality
When it comes to new windows, the quality and variety of services can often play just as important of a role in insulation and performance as the brand of window you choose. We do give window installers higher marks if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
We analyzed patterns in recent online reviews to determine the companies with the highest rates of customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it reflects the quality of services across most other categories, including warranty, cost, quality of parts, professionalism, quality of installation and more.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers try to keep costs as low as possible. When analyzing providers' prices, we gave higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed, windows are a serious investment, so you'll want to be certain that investment is well protected. Window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of Dunwoody's climate, homeowners will want to mitigate low efficiency, water damage and rot. We factored in local experience to reflect the ability of Dunwoody window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Dunwoody, GA Window Replacement FAQs
How much does window installation cost?
The national average cost of replacing one window is around $600 but can range from $200 to $1,200, based on a few different factors. The price is often dependent on the location of your property, the type and material of the window and the size of the window. Also, keep in mind that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.
What are the most common kinds of replacement windows?
