Calculate how much you can expect to pay for window installation and replacement in Buffalo Grove, IL using our customized window cost calculator.

How Installing Energy-Efficient Windows in Buffalo Grove Saves You Money
There are several benefits of upgrading to energy-efficient windows. A few reasons you may want to consider making the change include the following:
- Protect your investment: If your home is on the older side, your windows are most likely outdated. Upgrading your windows can improve the insulation in your home and also help raise the value of your home if you decide to sell.
- Better temperature control in your home: Living in a very cold city like Buffalo Grove can often mean depending on your heater to keep your home cool. Energy-efficient windows can lower how hard your heating system needs to work to heat your home.
- Save on power bills: Switching to energy-efficient windows reduces your energy bills by about 12% because you need less energy.
- Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
Estimated Cost of Window Replacement in Buffalo Grove
Each window installer offers varying services and has varying costs based on a few factors.
How Much Do New Windows Cost?
The typical cost to replace one window is about $600 but can range from $200 to $1,200. These figures vary depending on the specifics of your installation, like number of windows, material, the location of your home, type, size and more.
With windows, efficiency is the most important factor for most homeowners. High efficiency windows may cost more initially, but by increasing the efficiency of your home — particularly during the summer and winter — they can give you many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save Buffalo Grove homeowners $294+ per year after replacing single-pane windows.
Getting free quotes from several installers is the best way to find out which one is right for you.
What Services do Window Installers Offer?
In general, there are two kinds of window installation services companies offer: full-frame and pocket installations.
A full-frame installation replaces the full window, including the sill, frame, trim and the window panes. Because this type of installation is more involved, it will be more expensive than a pocket installation. A pocket installation involves installing a new window within the existing frame. So, instead of removing the whole unit and rebuilding it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.
Your window installation company can recommend the best type for your project. In Buffalo Grove, the choice will mostly depend on how much damage there is currently and how old your existing frames are.

How We Choose the Best Window Installers in Buffalo Grove
EcoWatch differs from most reviewers, as we look at these companies through a sustainability lens. Along with energy efficiency, we reviewed window companies all across the state and ranked them using the following methodology:
Service Area
Because this is a guide for Buffalo Grove, we paid more attention to companies that cover the city. There are other reputable providers that didn't make our list because they wouldn't be able to serve homeowners in Buffalo Grove.
Work Quality
When installing new windows, the quality and range of services can often play just as important of a role in insulation and performance as the type of window you get. We do give window installers more points if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
Another self-explanatory yet super important review factor is customer feedback. If most customers don't have nice feedback about their service from a certain company, it won't be featured on EcoWatch.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing the prices of providers, we awarded higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed, windows are a sizable investment, so you'll want to be certain that investment is well protected. Window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Lastly, 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.
Buffalo Grove, IL Window Replacement FAQs
How much should window installation cost?
The average cost to install a single window ranges between $450 and $650. There are many factors that influence how much it costs, including your property's location, local labor costs, the number of windows, the materials used in designing the windows, how energy-efficient the windows are and styles and sizes of windows.
Which type of window should I get?
Generally, double-pane windows will be more efficient than single-pane windows and windows that don't open are more efficient than windows that do. If you want to be sure you'll have the most energy-efficient windows, look for models that have the blue Energy Star certification attached to them — this means they're certified energy-efficient by the U.S. Department of Energy.
Can you install your own windows?
If you're handy and have the time and patience to do the job right, it's possible to install your own windows. But if you don't have the time or experience, we recommend getting a professional to do it for you.
How long does window installation generally take?
Because a window takes about 30 minutes to install, around 16 windows can be installed during an 8-hour work day.
