How Installing Energy-Efficient Windows in Buffalo Grove Saves You Money
By switching to energy-efficient windows, you can enjoy several benefits, such as:
- 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 on energy bills: Because energy-efficient windows lower the amount of energy used to heat or cool your home, the switch can help you save around $294 annually on your energy bills in Buffalo Grove.
- Protect your investment: If your home is on the older side, your windows are most likely outdated. Updating your windows can improve the insulation in your home and also help raise the value of your property if you decide to sell.
- Decrease your carbon footprint: By using less energy after upgrading to Energy Star certified windows, you’ll also be lowering your carbon dioxide emissions by about 12%, according to Energy Star.
Estimated Cost of Window Replacement in Buffalo Grove
Windows come in different styles, shapes and purposes, so costs and services will differ greatly based on several factors. Below, we detail the typical cost and services that you’ll find from window installation companies.
How Much Do New Windows Cost?
According to our research, the average cost of installing a single window is around $600. However, window replacement costs can range from $200 to $1,200 for each window. These amounts vary depending on the specifics of your installation, such as number of windows, type, the location of your home, size, material and more.
It’s also worth bearing in mind that energy-efficient windows will typically cost more initially, but Energy Star estimates that upgrading the windows on your Buffalo Grove home can mean an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 a 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.
Getting free quotes from multiple companies is the best way to find out which one is right for you.
What Services do Window Installers Offer?
The first step when considering a window replacement is to clarify whether you need a full-frame or pocket installation.
A full-frame installation replaces the complete window, such as the windowsill, frame, trim and the window panes. Because this kind of installation requires more time and labor, it will be more expensive than a pocket installation. Pocket installations are simpler and won’t cost as much because they involve merely replacing the window within its existing frame. But if the frame has any damage or deterioration, you should opt for a full-frame installation instead.
If you’re still trying to decide which type of installation you should get, you can ask your provider and get their advice. The decision mostly depends on the age of your window frames and if there’s any damage.

How We Choose the Best Window Installers in Buffalo Grove
In our search to make your home improvements easier and more eco-friendly in Buffalo Grove, the EcoWatch Reviews team chose the above companies as the best window installation companies in the city. Along with energy efficiency, we assessed several window installers in Buffalo Grove and assigned rankings using the following methodology:
Service Area
Since this is a guide for Buffalo Grove, we paid more attention to companies that provide services to the city. There are certainly other reputable providers that didn’t make our list because of the low odds that they would serve the average homeowner in Buffalo Grove.
Work Quality
When choosing new windows, the quality and range of services often plays just as important of a role in overall efficiency and performance as the brand of window you choose. We do give window installers more points if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
Customer feedback is another very important review factor. If the majority of customers don’t have positive things to say about their experience with a certain window installation company, you won’t see it featured on EcoWatch.
Cost
This one is a give-and-take: similar to most services, cheap window installation companies may not provide the highest quality service. Still, we want to ensure we’re highlighting companies that provide a variety of price and financing options so they’re accessible to most homeowners.
Warranty
As discussed previously, windows are a considerable investment, so you’ll want to be certain that investment is protected. Window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have been in the industry for quite some time. Window installation companies that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
Buffalo Grove, IL Window Replacement FAQs
What is the average cost to install windows?
The typical cost to install a window can range between $450 and $650. There are a variety of factors that influence the price, including the number of windows, the materials used in designing the windows, styles and sizes of windows, local labor costs, your property’s location and how energy-efficient the windows are.
What are the different kinds of windows?
The most common kinds of windows for homes include: transom windows, awning windows, casement windows, bay windows, picture windows, slider windows and double-hung and single-hung windows.
Do I really need to use a window installation company?
Unless you have home repair skills and have all the necessary tools to replace your own windows, we recommend hiring a professional installer. The process of installing windows is complex and can take anywhere from four to six hours for one window. Although it’s tempting to try to save some money by doing it yourself, hiring a company is a faster, more efficient and much safer option.
How long does window installation typically take?
Since the average installation time of a window is 30 minutes, around 16 windows can be installed in a typical 8-hour work day.
