How Installing Energy-Efficient Windows in Sterling Saves You Money
By switching to energy-efficient windows, you can take advantage of several benefits, including:
- Protect your investment: Upgrading your windows is an important part of maintaining your property and its real estate value, particularly if you have an older home.
- Decrease your carbon footprint: Reducing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by 449 pounds per year on average.
- Save on electricity bills: Since energy-efficient windows reduce the amount of energy used to heat or cool your home, the switch can help you save around $320 annually on your energy bills in Sterling.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out damaging UV rays, reducing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in Sterling
Windows come in various purposes, styles and shapes, 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 market research, the typical cost to install a single window is around $600. However, window installation costs can range from $200 to $1,200 per window. But costs differ considerably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also offer door installations, which will add extra costs to your project.
Whether or not you pick energy-efficient windows is another factor that will determine the cost. These will typically cost more than other windows, but on the other hand, you can save about $320 a year on your energy bills in Sterling.
How much your window installation costs will also vary based on the kind of window material you choose for the frames. Wood windows are usually the most expensive, but it depends on whether they are 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are more efficient.
What Services do Window Installers Offer?
The first thing to ask yourself when planning a window installation is: Do you need a full-frame installation or a pocket installation?
Full-frame installations are usually recommended when you want a new style or your window has significant rot or deterioration. With this service, your installers will replace the whole window, including the frame, sill and trim. Pocket installations (or retrofits) entail replacing a window within its existing frame, which makes pocket installations take less time and therefore cost less. But, if the frame has any damage or rot, you will likely need a full-frame installation instead.
If you’re still debating which kind of installation you should get, you can consult with your installer and get their recommendation. The choice mostly depends on how old the frames are and if there’s any damage present.

How We Choose the Best Window Installers in Sterling
EcoWatch reviews are different from other reviews because we evaluate these companies through a sustainability lens. We have decided to review the best window installers in Sterling mainly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows can reduce your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
This one is pretty self-explanatory, but we’ve chosen to highlight window installation companies that serve a wide variety of states and cities so you can find the best window installation company near you.
Work Quality
We’re certain that you’re looking for professionals who do a great job installing windows. We’ve vetted each installer on this list to make sure its technicians are well-qualified and that the company has received plenty of positive customer feedback to vouch for its service.
Customer Reviews
Customer feedback is another super important review factor. If most customers don’t have nice feedback about their service from a certain installer, it won’t be featured on EcoWatch.
Cost
Cheaper windows don’t necessarily mean better windows, but we know many of our readers want to keep costs as low as possible. When analyzing the prices of providers, 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. For that reason, window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have been in the industry for a while. Window installers that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Sterling, IL Window Replacement FAQs
What is the typical cost to install windows in a home?
The typical cost of installing a window can range between $450 and $650. There are many factors that affect how much it costs, such as the materials used in designing the windows, your property’s location, local labor costs, how energy-efficient the windows are, the number of windows and styles and sizes of windows.

The most common types of windows for homes are transom windows, bay windows, double-hung and single-hung windows, slider windows, casement windows, awning windows and picture windows.
Can I install my own windows?
Although it is possible to install your own windows, doing so is time-consuming and requires a lot of handiness. Using a window replacement company can help ensure that the installation is done properly and that you can avoid spending the time and effort of doing it yourself.
How do you know it’s time to replace your windows?
Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, they probably need to be replaced. Apart from that, if your windows have any damage on them, or they have become difficult to open or close, they may be in need of replacement.
