How Installing Energy-Efficient Windows in Mahomet Saves You Money
By switching to energy-efficient windows, you and your family can enjoy several benefits, including:
- Protect your valuables from fading: When you upgrade to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will fade less due to their ability to filter out harmful UV rays.
- Save money on energy bills: Upgrading to energy-efficient windows lowers your energy bills by about 12% because you need less energy.
- Protect your investment: When your home is on the older side, your windows could also be outdated or drafty. Upgrading your windows is an important part of maintaining your property and its real estate value.
- Better temperature control in your home: Living in a very cold place like Mahomet can often mean depending on your heater to keep your house cool. Energy-efficient windows can reduce how hard your heating system needs to work to heat your home.
Estimated Cost of Window Replacement in Mahomet
Let's go over the cost of replacing your windows and the kinds of services offered by installers.
How Much Do New Windows Cost?
The typical cost to install one window is about $600 but can range from $200 to $1,200. But costs vary remarkably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also provide door replacements, which will make your project cost more.
Keep in mind that energy-efficient windows may cost more upfront, but Energy Star predicts the upgrade will save you between $101 and $583 per year when you replace single-pane windows and between $27 and $197 per year when you replace double-pane, clear glass windows. These savings vary based on your local climate, energy rates and individual home characteristics.
Something else that affects the total cost is the material you select for your frame. Aluminum frames are typically the least pricey and are sturdy and light, but they offer poor insulation. On the other hand, wood frames are the most expensive 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?
In regard to window installations, in general there are two kinds that your installer will have: full-frame and pocket installations.
A full-frame installation replaces the full window, such as the sill, frame, trim and the window panes. Because this kind of installation requires more time, it will be more expensive than a pocket installation. Pocket installations (or retrofits) involve installing a new window within its existing frame, which makes pocket installations more simple and affordable. But, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.
Your window installation company should be able to help you figure out what's best for your needs. In Mahomet, the decision will mostly be based on the age of your windows and if there's any damage. Wood can decay if not properly maintained over the years, so it's good to have a professional examine your frames and window sills.

How We Choose the Best Window Installers in Mahomet
In our hunt to make your home improvements easier and more eco-friendly in Mahomet, the EcoWatch Reviews team examined many companies before settling on these. Along with energy efficiency, we assessed several window installers in Mahomet and assigned rankings using the following methodology:
Service Area
This one is self-explanatory, but we've chosen to highlight window installation companies that serve the Mahomet area so you can find the best window installation company near you.
Work Quality
When installing new windows, the quality and range of services often plays just as important of a role in overall efficiency and performance as the type of window you get. 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
Customer feedback is another super important review factor. If most customers don't have positive feedback about their experience with a certain installer, it won't be featured on EcoWatch.
Cost
This one is a give-and-take: similar to other services, cheap window installation companies are not going to provide the most quality service. Still, we want to ensure we're highlighting companies that offer a range of price and financing options so they're accessible to most homeowners.
Warranty
Protecting your investment in new windows is important. That's why window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of Mahomet's climate, homeowners will want to mitigate low efficiency, rot and water damage. We factored in local experience to reflect the ability of Mahomet window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Mahomet, IL Window Replacement FAQs
What is the average cost to replace windows?
The average cost to replace a single window ranges between $450 and $650. There are many factors that affect the cost, such as how energy-efficient the windows are, the materials used in designing the windows, your property's location, styles and sizes of windows, local labor costs and the number of windows.
Which kind of window should I get?
A window's energy efficiency depends on several 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 installation companies offer?
Window installation companies cover the entire process — from replacing old windows with new ones to cleaning up afterward. In addition, a lot of companies offer window manufacturing, customization and repairs.
Should I replace all my windows at once?
If you want to get more efficient windows and save money on energy costs, replacing all your windows at the same time is the only way to see a noticeable difference. On the other hand, if you have just one or two windows that are damaged or drafty, you can replace just those.
