How Installing Energy-Efficient Windows in Geneseo Saves You Money
Upgrading to energy-efficient windows can help improve the comfort of your home and help you save on power bills. Here are more ways switching out your windows could benefit you:
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
- Save money on energy bills: Since energy-efficient windows reduce the amount of energy used to heat or cool your home, the switch can help you save about $322 annually on your energy bills in Geneseo.
- Better temperature control in your home: When you reside in a city like Geneseo where the winters can get very cold, you usually need to rely on your heater to keep your house warm. Energy-efficient windows can lower how much heat is lost through your windows when heating your home.
- Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes tend to have windows that are outdated, drafty or potentially even damaged in some way.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 Geneseo
Each window installation company offers various services and has varying price points depending on a few factors.
How Much Do New Windows Cost?
Though the national average to replace a single window is around $600, it can range from $200 to $1,200. How much it will cost depends on several factors, such as size, the location of your home, type, number of windows, material and more.
It's also worth bearing in mind that energy-efficient windows will usually cost more initially, but Energy Star estimates that switching out the windows on your Geneseo home translates to 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. The amount of money you'll save by upgrading to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
Costs will also vary based on the material of your frame. Aluminum frames cost the least. They're sturdy, light and easy to maintain, but offer poor insulation. Vinyl frames are a bit more expensive and offer good insulation. Composite frames made using wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They're also aesthetically pleasing and offer decent insulation for your home.
What Services do Window Installers Offer?
There are generally two kinds of window replacement services: full-frame and pocket installations.
Full-frame installations involve replacing the whole window — the sill, frame, trim and all. These are most common when you want a different style for your windows or when it has a great amount of rot or deterioration. Full-frame installations are more comprehensive and will increase overall costs. A pocket installation involves installing a new window within the existing frame. This means instead of tearing out the whole window and rebuilding it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.
Your window installer can help you decide which type of installation you should get.

How We Choose the Best Window Installers in Geneseo
EcoWatch differs from most reviewers since we examine these companies through a sustainability lens. We've assessed the best window replacement companies in Geneseo primarily based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows can cut your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
Because this is a guide for Geneseo, we paid more attention to companies that cover the city. There are certainly other reputable providers that didn't make our list because they wouldn't be able to serve homeowners in Geneseo.
Work Quality
When picking new windows, the quality and variety of services can often play just as important of a role in insulation and performance as the type of window you choose. We do rate window installers higher if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
We analyzed trends in recent customer feedback to determine the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it indicates the quality of services across most other categories, including quality of parts, quality of installation, professionalism, cost, warranty and more.
Cost
This one is a give-and-take: similar to most services, cheap window installation companies may not provide the most quality service. On the other hand, we want to make sure we're highlighting companies that offer a spectrum of price and financing options so they're accessible to most homeowners.
Warranty
Protecting your investment in new windows is important. For that reason, window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have been in the industry for quite some time. Window installers that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Geneseo, IL Window Replacement FAQs
How much does window installation cost?
The average cost of replacing one window can range between $450 and $650. There are many factors that influence how much it costs, which include your property's location, the number of windows, styles and sizes of windows, local labor costs, how energy-efficient the windows are and the materials used in designing the windows.
What type of window is the best for energy efficiency?
A window's energy efficiency is affected by a variety of factors, such as the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are usually the most energy-efficient since they are certified by the U.S. Department of Energy.
When should I use a window installation company?
Unless you're handy and have the time needed to replace your own windows, we recommend hiring a professional installer. The window installation process is quite involved and can take anywhere from four to six hours for a single window. Although it's tempting to try to do it yourself to save money, hiring a company is a faster, more efficient and much safer alternative.
How do you know it's time to replace your windows?
Windows typically last 20 to 30 years, but anytime you notice damage on your windows, it's a good time to have an expert take a look at them to determine if they are in need of a repair or replacement.
