How Installing Energy-Efficient Windows in Oswego Saves You Money
By switching to energy-efficient windows, you can benefit in several ways, such as:
- Save on power bills: Because energy-efficient windows decrease the amount of energy used to heat or cool your home, they can help you save about $307 annually on your energy bills in Oswego.
- Decrease your carbon footprint: Since energy-efficient windows improve the insulation in your house, you can lower your carbon footprint by about 12%, according to Energy Star.
- Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent damage from the sun's UV rays to your floors, carpets and furniture.
- Protect your investment: When your home is on the older side, your windows could also be outdated or drafty. Upgrading and repairing your windows is an important part of maintaining your property and its value.
Estimated Cost of Window Replacement in Oswego
Windows come in varying shapes, styles and purposes, so costs and services will differ remarkably depending on your project. Below, we describe the typical cost and services that you’ll find from window installers.
How Much Do New Windows Cost?
Generally, Oswego homeowners can expect their replacement window installations to range from $250 to $1,200. The average cost sits at around $600. How much it will cost varies depending on several factors, such as number of windows, the location of your home, size, type, material and more.
It’s important to bear in mind that windows with the best efficiency may cost more upfront but can save you hundreds of dollars by lowering your energy bills. Investing in certified energy-efficient windows can save Oswego homeowners $307+ a year when 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?
When it comes to window replacements, there are typically two kinds that your provider will offer: full-frame and pocket installations.
Full-frame installations are usually done when you want a new style or your window has a lot of rot. With this service, your installers will replace the entire window, including the sill, trim and frame. Pocket installations (or retrofits) entail replacing a window within the existing frame, which makes pocket installations more simple and affordable. But, if the frame has any damage or rot, you should opt for a full-frame installation instead.
Your window installation company should be able to help you choose which type of installation you need.

How We Choose the Best Window Installers in Oswego
EcoWatch differs from most reviewers because we’re examining these companies through a sustainability lens. We have evaluated the best window installers in Oswego mostly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows can lower electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
Since this is a guide for Oswego, we gave more points to companies that provide services to the city. There are certainly other reputable providers that didn’t make the cut because of the low odds that they would serve the average homeowner in Oswego.
Work Quality
We’re certain that you’re looking for a company to do a great job installing windows. We’ve vetted each company in our guide to make sure its technicians are well-qualified and that the company has gotten tons of positive customer feedback to vouch for its service.
Customer Reviews
Another self-explanatory yet very important review factor is customer feedback. If most customers don’t have positive feedback about their service from a certain installer, it won’t be featured on EcoWatch.
Cost
Cheaper windows certainly don’t mean better windows, but we know many of our readers would like to keep costs low when possible. When analyzing the prices of providers, we gave higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
As discussed, windows are a substantial 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 a good track record in the industry. Window installers that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.
Oswego, IL Window Replacement FAQs
What is the typical cost to install windows?
The national average cost to replace one window is about $600 but can range between $200 and $1,200, based on a variety of factors. The price is often dependent on the location of your property, the type and material of the window and the size of the window. Also, bear in mind that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.
What are the different kinds of windows?
The most common kinds of windows for homes are transom windows, slider windows, double-hung and single-hung windows, bay windows, awning windows, casement windows and picture windows.
When do I need to use a window installation company?
Unless you have experience with home improvement projects and have the time to replace your own windows, we recommend hiring the pros. The window installation process is quite involved and can take anywhere from four to six hours for one window. Although it’s tempting to try to do it yourself to save money, hiring a professional is a faster, more efficient and much safer alternative.
When is the best time of year to replace windows?
Replacement windows can be installed during any season, but warmer weather is typically better. Regardless of when you install them, the contractors will take steps to ensure that too much hot or cold air doesn’t get into the home, so the temperature outside doesn’t necessarily matter that much. What’s most important is that the weather should be dry.
Should I replace my windows all at the same time?
If your windows are more than 20 years old, you most likely need to replace all of them. At that point, they are typically less efficient, leakier and/or more damaged than new windows. Doing your windows all at once will involve less paperwork and less time.
