How Installing Energy-Efficient Windows in Duluth Saves You Money
There are quite a few benefits of upgrading to energy-efficient windows. A few reasons you may want to consider making the change are the following:
- Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its real estate value, particularly if your home is on the older side.
- Protect your valuables from fading: When you upgrade to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will be protected from fading because of their ability to filter out damaging UV rays.
- Save on power bills: The Department of Energy estimates that heat gained or lost through windows accounts for about 25-30% of residential energy use. Switching to energy-efficient windows can help reduce that amount, which helps you save some money on your bills.
- Decrease your carbon footprint: Reducing the amount of energy you use also lowers your carbon emissions. You could reduce it by 476 pounds per year on average.
Estimated Cost of Window Replacement in Duluth
Let’s go over the cost of window installation and the kinds of services offered by installers.
How Much Do New Windows Cost?
The national average cost to replace a single window is about $600 but can range from $200 to $1,200. Costs will vary significantly based on your location, the quality of your products, the number of windows you need and the current condition of your home. Many window companies also offer replacement door installations and other add-ons like shutters, baths, coating and more. Additional services will increase overall project costs.
It’s also worth noting that energy-efficient windows will almost always cost more upfront, but Energy Star predicts that upgrading the windows on your Duluth home can mean an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. How much you’ll save by installing energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
Requesting free quotes from several providers is the best way to figure out which one is right for you.
What Services do Window Installers Offer?
There are typically two kinds of window installation services: full-frame and pocket installations.
Full-frame installations are usually recommended when you want to change the style of your windows or your window has significant deterioration. With this service, your installers will replace the whole window, including the sill, trim and frame. Pocket installations (or retrofits) involve replacing a window within its existing frame, which makes pocket installations less labor-intensive and costly. However, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.
Your window installation company can help you decide which type of installation you should get.

How We Choose the Best Window Installers in Duluth
EcoWatch reviews differ from other reviews, as we examine these companies through a sustainability lens. We’ve decided to evaluate the best window installers in Duluth mainly based on energy efficiency, as it’s what’s best for the environment and for you as a homeowner. Energy Star certified windows have been shown to lower electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
This one is self-explanatory, but we’ve chosen to highlight window installers that serve Duluth so you can find the right window installation company near you.
Work Quality
We’re willing to bet that you’re looking for professionals who do a great job installing windows. We’ve vetted each installer on this list to make sure its contractors are well-qualified and that the company has received tons of positive customer feedback to vouch for its service.
Customer Reviews
Customer feedback is another super important review factor. If most customers don’t have positive feedback about their service from a certain window installation company, it won’t be featured on EcoWatch.
Cost
This one is a give-and-take: as with most services, cheap window installers won’t always provide the highest quality service. Still, we want to ensure we’re highlighting companies that provide a variety of price and financing options so they’re accessible to most homeowners.
Warranty
As discussed previously, windows are a considerable investment, so you’ll want to make sure that investment is protected. Window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have been in the industry for a while. Window installation companies that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.
Duluth, GA Window Replacement FAQs
How much does window installation cost?
The average cost to install one window can range between $450 and $650.

Windows typically last 20 to 30 years, but anytime you see damage on your windows, it’s a good idea to have them checked by an expert to see if they need any repairs or replacements.

Each window takes about 30 minutes to install based on the kind of window. However, the window installation can take two days or more if you have a lot of windows that need to be installed.
