Why you can trust EcoWatch
Whether you're updating for aesthetics or have damaged windows, windows play a crucial role in conserving electricity in your home. If your house has old or damaged windows, your AC or heating system could be working overtime to heat or cool your home. This means higher electric bills.
That's also bad for the environment, as the additional energy used by drafty windows increases your carbon footprint.
Efficient windows are of particular importance in Oswego, where the temperature varies throughout the year. According to Energy Star, making the switch to energy-efficient windows can save the average homeowner up to $268 a year.

How Installing Energy-Efficient Windows in Oswego Saves You Money
Switching to energy-efficient windows can help improve the comfort of your home and help you save on energy bills. Here are more details about how upgrading your windows could help you:
- Protect your investment: If you have an older home, your windows are most likely in need of replacement. Upgrading your windows can make your home more comfortable and also help increase the value of your house if you decide to sell.
- Save money on power bills: Once you upgrade to energy-efficient windows, you can see a reduction in your bills by about 12% since you'll need less energy to heat or cool your home.
- Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% once you install Energy Star certified windows. In Oswego, that's about 449 pounds per year on average.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in Oswego
Each window replacement company provides various services and has different price points depending on a few factors.
How Much Do New Windows Cost?
Although the average of replacing a single window is around $600, it can range anywhere from $200 to $1,200. Costs will vary considerably depending on your location, the quality of your products, the number of windows you need and the current condition of your home. A lot of window companies also offer door installations and other add-ons like coating, shutters, baths and more. Additional services will increase overall project costs.
It's important to bear in mind that windows with the best efficiency may cost more upfront but can save you hundreds of dollars via returns on your energy bills. Investing in certified energy-efficient windows can save Oswego homeowners $268+ a year when replacing single-pane windows.
The cost of your window installation will also vary depending on the type of material you choose for the frames. Wood windows are generally the most expensive, but it depends if they are completely wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are shown to be more efficient.
What Services do Window Installers Offer?
The first question to ask yourself when planning on installing new windows is: Should you get a full-frame installation or a pocket installation?
Full-frame installations entail replacing the total window, including the sill, frame and trim. You most likely need a full-frame installation when you want a new style or your window has significant damage. Full-frame installations are more involved and will raise the total cost. Pocket installations are simpler and won't carry as large a bill because they entail merely replacing the window within its existing frame. But if the frame has any damage or rot, you may need a full-frame installation instead.
Your window installation company can recommend the best type for your project. In Oswego, the decision will mostly be based on the efficiency of your home and how old your existing frames are.

How We Choose the Best Window Installers in Oswego
EcoWatch differs from other reviewers, as we assess these companies through a sustainability lens. Along with energy efficiency, we reviewed each installer and ranked them using the following methodology:
Service Area
Because this is a guide for Oswego, we only included companies that provide services to the city. There are other reputable providers that didn't make our list because of the low odds that they would serve the average homeowner in Oswego.
Work Quality
We're certain that you're not looking for a company to do a shoddy job installing windows. We've vetted each company featured in our guide to make sure its technicians 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 the majority of customers don't have positive feedback about their service from a certain company, you won't see it featured on EcoWatch.
Cost
This one is a give-and-take: similar to most services, cheap window companies may not provide the highest quality service. Still, we want to ensure we're highlighting companies that provide a wide range of price and financing options so they're accessible to most homeowners.
Warranty
As discussed, windows are a considerable investment, so you'll want to make sure that investment is protected. Window installation companies with lengthy warranties for products, parts and labor 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.
Oswego, IL Window Replacement FAQs
How much does a window install cost?
The average cost to install a single window can range between $450 and $650. There are several factors that influence how much it costs, including how energy-efficient the windows are, styles and sizes of windows, the number of windows, your property's location, local labor costs and the materials used in designing the windows.
What are the kinds of windows?
There are several different types of windows you can get for your house, such as picture windows, transom windows, double-hung and single-hung windows, slider windows, casement windows, awning windows and bay windows.
Do I really have to use a window installation company?
You should hire a window installation professional whenever you want to upgrade your windows. Installing windows is a involved process that can be difficult and time-consuming, so it's best handled by the professionals.
When is the best time of year to replace windows?
Though you can install windows any time of year, warmer weather is generally better for installing replacement windows. In addition, it shouldn't be raining, as rain can make the installation more difficult.
Should I replace all my windows at the same time?
If you want to get more efficient windows and save money on energy costs, replacing all the windows at once is the only way to see a noticeable difference. However, if you have only one or two windows that are broken or drafty, you can replace just those.
