How Installing Energy-Efficient Windows in Mendota Saves You Money
There are several benefits of switching to energy-efficient windows. A few reasons you may want to consider making the switch are the following:
- Save money on energy bills: After you switch to energy-efficient windows, you can expect a reduction in your bills by about 12% since you'll require less energy to heat or cool your house.
- Decrease your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% when you install Energy Star certified windows. In Mendota, that's about 642 pounds per year on average.
- Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent damage from the sun's UV rays to your floors, carpets and furniture.
- Protect your investment: Upgrading your windows is an important part of maintaining your property and its value, especially if you have an older home.
Estimated Cost of Window Replacement in Mendota
Each window replacement company provides various services and has varying prices based on a few factors.
How Much Do New Windows Cost?
The national average cost to replace a single window is about $600 but can range anywhere from $200 to $1,200. This is because the cost of window installations are based on a variety of factors specific to your home, such as the size, material and number of windows you need to replace, as well as the location of your property.
It's also worth bearing in mind that energy-efficient windows will cost more initially, but Energy Star estimates that switching out the windows on your Mendota 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. The amount of money you'll save by switching to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
Another factor that affects the total cost is the material of the frame you select. Aluminum frames are typically the least pricey and are sturdy and light, but they offer poor insulation. On the other hand, wood frames cost the most, as 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?
There are typically two types of window replacement services: full-frame and pocket installations.
Full-frame installations are necessary when you want to change the style of your windows or your window has a lot of rot or deterioration. With this service, your professionals will replace the complete window, including the frame, sill and trim. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are on the simpler end and won't carry as large a bill, but you can't do this type of installment if you have any pre-existing rot or water damage.
Your window installation company can advise you on the best type for your project. In Mendota, the decision will mostly be influenced by how much damage there is currently and the age and condition of your existing frames.

How We Choose the Best Window Installers in Mendota
EcoWatch reviews are different from other reviews since we examine these companies through a sustainability lens. We have assessed the top window replacement companies in Mendota mainly based on energy efficiency, as it's the most sustainable option and the best one for homeowners. Energy Star certified windows have been shown to reduce your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
Because this is a guide for Mendota, we paid more attention to companies that cover the city. There are certainly other reputable providers that didn't make the cut because they wouldn't be able to serve homeowners in Mendota.
Work Quality
When installing new windows, the quality and range of services often plays just as important of a role in insulation and performance as the type of window you opt for. 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 patterns in recent customer feedback to determine the companies with the most customer satisfaction. Customer satisfaction may be the most important factor, as it indicates the quality of services across nearly every category, including quality of parts, cost, warranty, quality of installation, professionalism and more.
Cost
This one is a give-and-take: as with other services, cheap window installers may not provide the highest quality service. On the other hand, we want to ensure 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. That's why window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to Mendota's climate, homeowners need to be wary of water damage, low efficiency and rot. We factored in local experience to reflect the ability of Mendota window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Mendota, IL Window Replacement FAQs
How much should window installation cost?
The national average cost of replacing one window is around $600 but can range between $200 and $1,200, based on a variety of factors. The price is generally influenced by the type and material of the window, the location of your property and the size of the window. Also, keep in mind that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.
What are the types of windows?
There are several different kinds of windows you can get for your house, such as casement windows, bay windows, double-hung and single-hung windows, awning windows, slider windows, picture windows and transom windows.
Can I install my own windows?
While it is possible to install your own windows, doing so is time-consuming and requires a lot of experience with home improvement projects. Hiring a professional can help guarantee that the installation is done properly and that you won't have to spend the time and effort to do it yourself.
When is the best time of year to replace windows?
Even though you can install windows any time of year, warmer weather is typically better for replacing windows. In addition, it shouldn't be raining, as rain can make the installation more difficult.
How often do you need to replace windows?
Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, they should probably be replaced. Other than that, if your windows have damage anywhere on them, or they have become difficult to open or close, they may need to be replaced.
