How Installing Energy-Efficient Windows in Belleville Saves You Money
By upgrading to energy-efficient windows, you and your family can benefit in several ways, including:
- Decrease your carbon footprint: You can reduce your carbon footprint by about 12% after you install Energy Star certified windows. In Belleville, that’s about 642 pounds per year on average.
- Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.
- Save on electricity bills: According to the Department of Energy, heat gained or lost through windows accounts for about 25-30% of residential energy use. Replacing your windows with energy-efficient models can help lower that amount, therefore saving you about 12% more on your bills.
- Protect your investment: Upgrading your windows is an important part of maintaining your property and its value, particularly if your home is on the older side.
Estimated Cost of Window Replacement in Belleville
When looking into window installation, each company offers different services and prices. Let’s take a look at some typical costs and services.
How Much Do New Windows Cost?
Although the national average cost to replace one window is around $600, it can range from $200 to $1,200. This is because the cost of window installations depend on a variety of factors specific to your home, including the size, material and number of windows you need to replace, as well as the location of your property.
It’s also worth keeping in mind that energy-efficient windows will typically cost more upfront, but Energy Star estimates that switching out the windows on your Belleville home can mean an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. How much you’ll save by installing energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
Requesting free quotes from several installers is the best way to find out which one will work best for your budget.
What Services do Window Installers Offer?
Generally, there are two types of window installation services companies offer: full-frame and pocket installations.
Full-frame installations are usually recommended when you want to change the style of your windows or your window has a lot of rot. With this service, your professionals will replace the whole window, including the sill, trim and frame. Pocket installations (or retrofits) involve replacing a window within the existing frame, which makes pocket installations take less time and therefore cost less. But, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.
If you’re hiring a reputable window installation company, your company will be able to advise you on the best type for your project. In Belleville, the choice will mostly be based on the efficiency of your home and the condition of your existing frames.

How We Choose the Best Window Installers in Belleville
In our search to make your home improvements easier and more eco-friendly in Belleville, EcoWatch chose the above companies as the best window installation companies in the city. We have evaluated the best window installers in Belleville primarily based on their energy efficient offerings, as it’s what’s best for the environment and for you as a homeowner. Energy Star certified windows have been shown to lower 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 Belleville, we gave more points to companies that provide services to the city. There are certainly reputable providers that didn’t make our list because they wouldn’t be able to serve homeowners in Belleville.
Work Quality
When it comes to new windows, the quality and range of services often plays just as important of a role in insulation and performance as the brand of window you choose. We do give window installers higher marks if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
We analyzed patterns in recent customer feedback to determine the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across most other categories, including quality of parts, cost, quality of installation, professionalism, warranty and more.
Cost
Cheaper windows don’t necessarily mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing providers’ prices, we awarded higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
Protecting your investment in new windows is important. That’s why window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have a proven track record in the industry. 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.
Belleville, IL Window Replacement FAQs
How much should a window install cost?
The national average cost to replace a window is about $600 but can range between $200 and $1,200, depending on a variety of factors. The price is often dependent on the type and material of the window, the size of the window and the location of your property. Also, remember 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 most common types of replacement windows?
The most common types of windows for homes include: bay windows, awning windows, slider windows, transom windows, picture windows, casement windows and double-hung and single-hung windows.
When do I need to use a window installation company?
Unless you have home repair skills and have the time to replace your own windows, we recommend hiring a professional installer. The process of installing windows is quite involved and can take anywhere from four to six hours for a single window. Although it’s tempting to try to save some money by doing it yourself, hiring a professional is a faster, more efficient and safer alternative.
Should I replace my windows all at once?
If you’re upgrading your windows to save on your energy bills, replacing all the windows at once 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 leaky, you can replace just those.
How long does it take to install windows?
Because a window takes about 30 minutes to install, around 16 windows can be installed in an 8-hour work day.
