How Installing Energy-Efficient Windows in Duluth Saves You Money
When you switch to energy-efficient windows, you may see several perks, including:
- Protect your investment: When your home is on the older side, your windows could also be outdated or damaged. Keeping your windows up to date is an important part of maintaining your property and its value.
- Save on power bills: Because energy-efficient windows decrease how much energy you need to heat or cool your home, the switch can help you save around $607 annually on your energy bills in Duluth.
- Decrease your carbon footprint: Because energy-efficient windows improve the insulation in your house, you can cut your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out damaging UV rays, reducing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in Duluth
Each window installation company offers various services and has varying costs depending on a few factors.
How Much Do New Windows Cost?
Though the average cost to replace a single window is about $600, it can range from $200 to $1,200. These numbers vary depending on the specifics of your installation, such as size, the location of your home, type, material, number of windows and more.
Whether or not you opt for energy-efficient windows is another factor that will determine the cost. These will usually cost more than other windows, but on the other hand, you can save about $607 a year on your energy bills in Duluth.
We advise requesting free quotes from multiple window installation companies to find the right windows and the company that works best for your budget.
What Services do Window Installers Offer?
In regard to window installations, in general there are two kinds that your provider will offer: full-frame and pocket installations.
Full-frame installations are usually done when you want to change the style of your windows or your window has a lot of rot or deterioration. With this service, your installers will replace the whole window, including the frame, trim and sill. A pocket installation entails replacing a window within the existing frame. This means instead of removing the whole window and reinstalling it, the window installer will just put the replacement window (also called a retrofit or insert window) into the frame.
Your window installer can help you choose which type of installation you should get.

How We Choose the Best Window Installers in Duluth
In our search to find the most reliable, eco-friendly window installers in Duluth, the EcoWatch team examined many companies before landing on these. Along with energy efficiency, we reviewed window companies all across the state and ranked them based on the following methodology:
Service Area
Because this is a guide for Duluth, we only included companies that provide services to the city. There are other reputable providers that didn’t make the list because of the low odds that they would serve the average homeowner in Duluth.
Work Quality
When installing new windows, the quality and breadth of services can often play just as important of a role in overall efficiency and performance as the brand 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 find the companies with the most consistent customer satisfaction. Customer satisfaction might be the most important factor, as it indicates the quality of services across nearly every category, including professionalism, quality of installation, cost, quality of parts, warranty and more.
Cost
Cheaper windows certainly don’t mean better windows, but we know many of our readers want to keep costs as low as possible. When analyzing the prices of providers, we gave 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. For that reason, window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have been in the industry for quite some time. Window installation companies that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
Duluth, MN Window Replacement FAQs
What is the average cost to replace windows in a home?
The national average cost of installing one window is around $600 but can range from $200 to $1,200, based on several factors. The price is usually dependent on the size of the window, the location of your property and the type and material of the window. Also, remember that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.
Which kind of window should I get?
A window’s energy efficiency is influenced by a number of factors, such as the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are typically the most energy-efficient and are certified by the U.S. Department of Energy.
What services do window replacement companies offer?
Window installation professionals go to your home to remove your old windows and replace them with new ones. Some companies install products manufactured by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation is complete.
How do you know it’s time to replace your windows?
Windows generally last 20 to 30 years, but anytime you notice damage on your windows, it’s a good time to have them checked by an expert to see if they need any repairs or replacements.
