How Installing Energy-Efficient Windows in Dunwoody Saves You Money
There are several benefits of upgrading to energy-efficient windows. Some reasons you may want to consider making the switch are the following:
- Protect your investment: If you have an older home, your windows are most likely in need of replacement. Upgrading your windows can improve the insulation in your home and also help raise the value of your property if you decide to sell.
- Reduce your carbon footprint: You can reduce your carbon footprint by about 12% after you install Energy Star certified windows. In Dunwoody, that's about 476 pounds per year on average.
- Protect your valuables from fading: When you switch to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will be protected from fading due to their ability to filter out harmful UV rays.
- Save on power bills: After you install energy-efficient windows, you can see a reduction in your bills by about 12% since you'll use less energy to heat or cool your home.
Estimated Cost of Window Replacement in Dunwoody
Windows come in varying styles, shapes and purposes, so costs and services will differ remarkably depending on several factors. Below, we detail the average cost and services that you'll find from window installation companies.
How Much Do New Windows Cost?
On average, Dunwoody homeowners can anticipate their window replacements to range from $250 to $1,200. The most common installations sit at approximately $600. This is because window installations depend on a variety of factors specific to your home, including the size, material and number of windows you need to install, as well as the location of your property.
With windows, efficiency is one of the most important factors for many homeowners. High efficiency windows may cost more initially, but by increasing the efficiency of your home — particularly if you live in a hot climate — they can provide decades of energy savings. According to Energy Star, buying certified energy-efficient windows can save Dunwoody homeowners $389+ per year after replacing single-pane windows.
Another factor that influences the total cost is the material of the frame you pick. Aluminum frames are typically the least pricey and are sturdy and light, but they provide poor insulation. On the other hand, wood frames cost the most, as 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?
In regard to window replacements, in general there are two types that your provider will have: full-frame and pocket installations.
Full-frame installations involve replacing the whole 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 a great amount of rot or deterioration. Full-frame installations are more involved and will increase overall costs. Pocket installations are on the simpler end and won't carry as large a bill because they involve simply replacing the window within its existing frame. But if the frame has any damage, you may need a full-frame installation instead.
If you're not sure which kind of window installation service you should get, your installer should be able to help you out. Generally, the choice is influenced by factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Dunwoody
EcoWatch differs from other reviewers, as we assess these companies through a sustainability lens. Along with energy efficiency, we evaluated window companies all across the state and ranked them based on the following methodology:
Service Area
Because this is a guide for Dunwoody, we gave more points to companies that serve the city. There are certainly reputable providers that didn't make the list because of the low odds that they would serve the average homeowner 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 insulation and performance as the brand you opt for. 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 most consistent customer satisfaction. Customer satisfaction might be the factor we place the most value on, as it reflects the quality of services across nearly every category, including quality of parts, quality of installation, cost, professionalism, warranty and more.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers would like to keep costs low when possible. When analyzing providers' prices, we awarded higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
Protecting your investment in new windows is important to many homeowners. That's why window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of Dunwoody's climate, homeowners need to be wary of low efficiency, rot and water damage. 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.
Dunwoody, GA Window Replacement FAQs
How much should window installation cost?
The typical cost to replace one window ranges from $450 to $650. There are a variety of factors that affect how much it costs, including your property's location, local labor costs, the number of windows, the materials used in designing the windows, styles and sizes of windows and how energy-efficient the windows are.
What kind of window is the most energy-efficient?
Generally, double-pane windows will be more efficient than single-pane windows and windows that don't open will be more efficient than windows that do. To be sure you'll get the most energy-efficient windows, look for models that have the blue Energy Star certification — they're certified energy-efficient by the U.S. Department of Energy.
Can I install my own windows?
If you're handy and have experience with installing a replacement window, you may be able to install your own windows. However, if you don't have the time or know-how, we recommend hiring a professional.
How long does it generally take to install windows?
Each window takes about 30 minutes to install depending on the kind of window. However, the window installation can be a two-day job — or more — if you have a lot of windows that need to be installed.
What time of year is a good time to replace my windows?
Even though you can install windows any time of year, warmer weather is typically better for installing replacement windows. In addition, the weather should be dry, since rain can make the installation more difficult.
