How Installing Energy-Efficient Windows in Sterling Saves You Money
By switching to energy-efficient windows, you can enjoy several benefits, such as:
- Protect your investment: If you have a relatively old home, your windows are most likely in need of replacement. Updating your windows can make your home more comfortable and also help increase the value of your property if you decide to sell.
- Decrease your carbon footprint: By using less energy once upgrading to energy-efficient windows, you’ll also be decreasing your carbon dioxide emissions by about 12%, according to Energy Star.
- Save money on power bills: Switching to energy-efficient windows lowers your energy bills by about 12% because you need less energy.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only insulate your home better, but also filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
Estimated Cost of Window Replacement in Sterling
Windows come in varying shapes and sizes, so costs and services will differ remarkably. Here are the typical costs and the primary services that you can find from window installers.
How Much Do New Windows Cost?
Even though the typical cost of installing a single window is about $600, it can range from $200 to $1,200. But prices 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 companies also offer door replacements, which will add extra costs to your project.
With windows, efficiency is the most important factor for most homeowners. Windows with higher efficiency may cost more initially, but by increasing the efficiency of your home — especially during the summer and winter — they can provide decades of energy savings. According to Energy Star, buying certified energy-efficient windows can save Sterling homeowners $320+ per year after replacing single-pane windows.
Requesting free quotes from multiple installers is the best way to figure out which one will work best for your budget.
What Services do Window Installers Offer?
Generally, there are two types of window replacement services companies provide: full-frame and pocket installations.
Full-frame installations are usually done when you want a new style or your window has a lot of deterioration. With this service, your installers will replace the complete window, including the sill, frame and trim. Pocket installations are on the simpler end and won’t cost as much because they involve simply replacing the window within its existing frame. But if the frame has any damage or deterioration, you may need a full-frame installation instead.
If you’re still debating which type of installation you should get, you can talk to your provider and get their advice. 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 differ from most reviews since we look at these companies through a sustainability lens. We have evaluated the best window replacement companies in Sterling 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 can reduce your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
This one is self-explanatory, but we’ve chosen to highlight window installers that serve Sterling so you can find a quality window installation company near you.
Work Quality
We’re certain that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each installer featured in our guide to make sure its contractors are well-qualified and that the company has received lots of positive customer feedback to vouch for its service.
Customer Reviews
Another self-explanatory yet super important review factor is customer feedback. If most customers don’t have positive feedback about their experience with a certain company, you won’t see it featured on EcoWatch.
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 gave higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
Protecting your investment in new windows is important to many homeowners. That’s why window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have been in the industry for quite some time. Window installers that have more experience 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?
The national average cost of replacing a single window is about $600 but can range from $200 to $1,200, depending on a variety of factors. The price is often influenced by the type and material of the window, the size of the window and the location of your property. Also, bear in mind that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.
What are the most common types of replacement windows?
There are various kinds of windows you can get for your home, such as transom windows, picture windows, casement windows, slider windows, bay windows, double-hung and single-hung windows and awning windows.
Can you install your own windows?
If you’re handy and know how to replace a window, you may be able to install your own windows. But if you don’t have the time or know-how, we don’t recommend it.
When is the best time of year to replace windows?
Even though you can install windows any time of year, warmer weather is typically better for installing replacement windows. In addition, the weather should be dry, since rain can make the installation more difficult.
How often should you replace your windows?
Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, then 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.
