Why you can trust EcoWatch
Although green energy sources like wind and solar are important when it comes to reducing your carbon footprint, improving your home’s energy efficiency can also have a big impact on home energy conservation. If your house has old or damaged windows, your AC or heater could be working overtime to heat or cool your house. This means higher electricity bills.
That’s not great for your bank account or the environment, but one of the top window installation companies can help with that.
Efficient windows are especially important in Hanover, where the temperature varies throughout the year. According to Energy Star, making the switch to energy-efficient windows can save the average homeowner up to $295 a year.

How Installing Energy-Efficient Windows in Hanover Saves You Money
By switching to energy-efficient windows, you and your family can take advantage of several benefits, such as:
- 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.
- Protect your investment: If you have a relatively old home, your windows are most likely outdated. Upgrading your windows can make your home more comfortable and also help increase the value of your house if you decide to sell.
- Save money on electricity bills: Once you install energy-efficient windows, you can see a reduction in your bills by about 12% because you’ll need less energy to heat or cool your house.
- Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% after you install Energy Star certified windows. In Hanover, that’s about 449 pounds per year on average.
Estimated Cost of Window Replacement in Hanover
When researching window installation, each company provides different services and costs. Let’s go over some typical costs and services.
How Much Do New Windows Cost?
Typically, Hanover homeowners can expect their replacement window installations to range from $250 to $1,200. The most common installations sit at approximately $600. Costs will vary considerably based on the current condition of your home, the quality of your products, your location and the number of windows you need. A lot of window companies also offer replacement door installations and other add-ons like coating, shutters, baths and more. Additional services will increase overall project costs.
It’s important to remember that windows with higher efficiency may cost more upfront but can save you hundreds of dollars via returns on your energy bills. Investing in certified energy-efficient windows can save Hanover homeowners $295+ a year when replacing single-pane windows.
Getting free quotes from multiple installers is the best way to find out which one is right for you.
What Services do Window Installers Offer?
The first thing to ask yourself when considering a window replacement is: Should you get a full-frame installation or a pocket installation?
Full-frame installations involve replacing the entire window — the sill, frame, trim and all. These are most common when you want a new style for your windows or when it has a great amount of deterioration. Full-frame installations require more time and labor and will increase overall costs. Pocket installations (also known as retrofits) are when you replace a window while leaving the old frame. Pocket installations are simpler and won’t carry as large a bill, but you can’t do this kind of installment if you have any pre-existing rot or water damage.
Your window installation company can help you decide which type of installation you should get.

How We Choose the Best Window Installers in Hanover
In our hunt to make your home improvements easier and more eco-friendly in Hanover, the EcoWatch Reviews team assessed dozens of companies before settling on these. Along with energy efficiency, we analyzed window companies all across the state and assigned rankings using the following methodology:
Service Area
This one is pretty self-explanatory, but we’ve chosen to highlight window installers that serve a wide variety of states and cities so you can find the best window installation company near you.
Work Quality
We’re willing to bet that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each installer included in our guide to ensure its contractors are well-qualified and that the company has gotten tons of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed patterns in recent customer feedback to find the companies with the most consistent customer satisfaction. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across most other categories, including professionalism, cost, quality of installation, quality of parts, warranty and more.
Cost
Cheaper windows certainly don’t 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 gave higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
Protecting your investment in new windows is important. For that reason, window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of Hanover’s climate, homeowners need to be wary of low efficiency, rot and water damage. We factored in local experience to reflect the ability of Hanover window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Hanover, IL Window Replacement FAQs
What is the average cost to replace windows?
The typical cost to replace a window can range from $450 to $650. There are many factors that affect how much it costs, such as styles and sizes of windows, local labor costs, the number of windows, the materials used in designing the windows, how energy-efficient the windows are and your property’s location.
Which type of window should I get?
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.
Do you really need to use a window installation company?
You should use a window installation company whenever you need new windows. Installing windows is a complex process that can take a lot of time, so it’s best left to the professionals.
What time of year is a good time to replace my windows?
Replacement windows can be installed during any season, but warmer weather is typically better. No matter when you install them, the contractors will take steps to make sure that too much hot or cold air doesn’t get into the house, so the temperature outside isn’t necessarily a big factor. What’s most important is that the weather should be dry.
How often do you need to replace your windows?
Windows typically have a lifespan of 20 to 30 years, but anytime you see damage on your windows, it’s a good time to have them checked by an expert to see if they need any repairs or replacements.
