How Installing Energy-Efficient Windows in Dunwoody Saves You Money

By upgrading to energy-efficient windows, you can enjoy several benefits, including:

• Reduce your carbon footprint: In Dunwoody, you can reduce your indirect greenhouse gas emissions by about 476 pounds per year after you upgrade to energy-efficient windows.
• Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.
• Save money on energy bills: Because energy-efficient windows reduce how much energy you need to heat or cool your home, the switch can help you save around $362 annually on your energy bills in Dunwoody.
• Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes tend to have windows that are outdated, leaky or potentially even damaged in some way. Updating your windows could help raise the value of your property if you decide to sell.

Estimated Cost of Window Replacement in Dunwoody

Let’s go over the cost of window installation and the kinds of services offered by installers.

How Much Do New Windows Cost?

According to our research, the typical cost of replacing a single window is around $600. However, window replacement costs can range from $200 to $1,200 for each window. Costs will vary significantly depending on the quality of your products, the current condition of your home, your location and the number of windows you need. A lot of window companies also offer replacement door installations and other add-ons like baths, shutters, coating and more. Additional services will increase overall project costs.

Bear in mind that energy-efficient windows may cost more, but Energy Star estimates the upgrade will save you between $101 and $583 per year when you install single-pane windows and between $27 and $197 per year when you install double-pane, clear glass windows. Your savings will vary based on your local climate, energy rates and individual home characteristics.

Another factor that influences the overall cost is the material you choose for your frame. Aluminum frames are generally the least pricey and are sturdy and light, but they provide poor insulation. On the other hand, wood frames are the most expensive because they are aesthetically pleasing and provide 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 generally two types of window installation services: full-frame and pocket installations.

Full-frame installations require replacing the full window — the sill, frame, trim and all. These are typically done when you want a new style for your windows or when it has a great amount of rot or deterioration. Full-frame installations require more time and labor and will increase overall costs. A pocket installation involves installing a new window without replacing the frame. So, instead of taking out the whole window and rebuilding it, the window installer will just slide the replacement window (also called a retrofit or insert window) into the frame.

Your window replacement company will be able to help you understand what’s best for your needs. In Dunwoody, the decision will mostly be based on the age of your windows and if there’s any damage. Wood can decay if it’s not properly maintained over the years, so it’s good to have a professional evaluate your frames and window sills.

How We Choose the Best Window Installers in Dunwoody

In our search to make your home improvements easier and more eco-friendly in Dunwoody, EcoWatch assessed many companies before deciding on these. Along with energy efficiency, we assessed each installer and ranked them using the following methodology:

Service Area

Because this is a guide for Dunwoody, we only included companies that cover the city. There are certainly reputable providers that didn’t make the list because they wouldn’t be able to serve homeowners in Dunwoody.

Work Quality

When it comes to new windows, the quality and breadth of services can often play just as important of a role in overall efficiency and performance as the type of window you get. We do give window installers more points 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 find the companies with the highest rates of customer satisfaction. Customer satisfaction might be the factor we place the most value on, as it reflects the quality of services across most other categories, including warranty, cost, professionalism, quality of parts, quality of installation and more.

Cost

This one is a give-and-take: as with other services, cheap window installation companies may not provide the highest quality service. On the other hand, we want to ensure we’re highlighting companies that provide a spectrum of price and financing options so they’re accessible to most homeowners.

Warranty

As discussed, windows are a sizable investment, so you’ll want to be certain that investment is protected. Window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Due to Dunwoody’s climate, homeowners will want to mitigate water damage, low efficiency and rot. We factored in local experience to reflect the ability of Dunwoody window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
