Why you can trust EcoWatch
A review of the best window installation companies in Dupo may not seem like the most captivating article on the EcoWatch site, but trust us, windows impact your life more than you might realize. If your house has traditional, outdated windows, your HVAC system could be working extra hard to heat or cool your home. This means spending more on power bills.
That's also bad news for the environment, as the additional energy used by outdated windows increases your carbon footprint.
Unlike other sites, EcoWatch ranks window installation companies based on energy efficiency while also balancing cost, customer satisfaction and service area.

How Installing Energy-Efficient Windows in Dupo Saves You Money
Energy-efficient windows can benefit you in several ways. Here are some reasons you may want to think about making the switch:
- Protect your investment: When your home is on the older side, your windows could also be outdated or damaged. Upgrading your windows is an important part of maintaining your property and its real estate value.
- Protect your valuables from fading: When you upgrade to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less because of their ability to filter out damaging UV rays.
- Save money on electricity bills: Upgrading to energy-efficient windows lowers your energy bills by about 12% since you use less energy.
- Decrease your carbon footprint: Because energy-efficient windows improve the insulation in your home, you can lower your carbon footprint by about 12%, according to Energy Star.
Estimated Cost of Window Replacement in Dupo
Windows come in different shapes and sizes, so costs and services will vary considerably. Here are the average costs and services that you can find from window installation companies.
How Much Do New Windows Cost?
Generally, Dupo homeowners can anticipate their window installations to range from $250 to $1,200. The average cost sits at about $600. Costs will vary significantly depending on your location, the quality of your products, the number of windows you need and the current condition of your home. A lot of 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 keeping in mind that energy-efficient windows will almost always cost more initially, but Energy Star estimates that upgrading the windows on your Dupo home can mean an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. How much you'll save by upgrading to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
Something else that affects the overall cost is the material of the frame you pick. Aluminum frames are generally the least expensive and are sturdy and relatively maintenance-free, 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 and cost somewhere between the other two.
What Services do Window Installers Offer?
The first question to ask yourself when planning on installing new windows is: Do you need a full-frame installation or a pocket installation?
A full-frame installation replaces the complete window, such as the windowsill, frame, trim and the window panes. As this type of installation requires more time and labor, it will be more expensive than a pocket installation. Pocket installations are simpler and won't carry as large a bill, as they involve simply replacing the window within its existing frame. But if the frame has any damage or deterioration, you may have to get a full-frame installation instead.
If you're unsure which type of window installation service you should get, your installer can assist you. In general, the choice is influenced by factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Dupo
In our search to find the most reliable, eco-friendly window installers in Dupo, EcoWatch landed on the above companies as the top window installation companies in the city. We've decided to assess the top window replacement companies in Dupo primarily based on their energy efficient offerings, as it's the most sustainable option and the best one for homeowners. Energy Star certified windows can lower energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installers that serve Dupo so you can find a quality window installation company near you.
Work Quality
When it comes to new windows, the quality and range of services can often play just as important of a role in overall efficiency and performance as the brand you opt for. 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
Customer feedback is another very important review factor. If the majority of customers don't have good feedback about their experience with a certain company, you won't see it featured on EcoWatch.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers try to keep costs as low as possible. When analyzing the prices of providers, we awarded higher scores 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 Dupo's climate, homeowners will want to mitigate rot, low efficiency and water damage. We factored in local experience to reflect the ability of Dupo window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Dupo, IL Window Replacement FAQs
What is the average cost to install new windows?
The typical cost to install one window ranges between $450 and $650. There are many factors that affect how much it costs, such as your property's location, local labor costs, the materials used in designing the windows, how energy-efficient the windows are, the number of windows and styles and sizes of windows.
Which kind of window is the best?
Generally, double-pane windows are more efficient than single-pane windows and windows that do not open are more efficient than windows that do. If you want to be sure you're getting 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.
When should I use a window installation company?
Unless you have experience with home improvement projects and have the time to replace your own windows, we recommend hiring a professional installer. The process of installing windows is complicated and can take anywhere from four to six hours for one window. Although it's tempting to try to do it yourself to save money, hiring a professional is a faster, more efficient and safer alternative.
When is the best time of year to replace windows?
While you can install windows any time of year, warmer weather is generally better for installing replacement windows. Additionally, the weather should be dry, since rain can make the installation harder.
When is it time to replace your windows?
Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, they probably need to be replaced. Other than that, if your windows have any damage on them, or they have become difficult to operate, they may be in need of replacement.
