How Installing Energy-Efficient Windows in Oak Park Saves You Money
When you switch to energy-efficient windows, you may see several benefits, including:
- 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.
- Reduce your carbon footprint: In Oak Park, you can cut your indirect greenhouse gas emissions by about 117 pounds per year when you install energy-efficient windows.
- Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Updating your windows can make your home more comfortable and also help raise the value of your property if you decide to sell.
- Save money on power bills: Switching to energy-efficient windows lowers your energy bills by about 12% because you need less energy.
Estimated Cost of Window Replacement in Oak Park
Windows come in all shapes and sizes, so costs and services will vary tremendously. Here are the average costs and services that you'll find from window installers.
How Much Do New Windows Cost?
According to our research, the national average cost to install a single window is about $600. However, window replacement costs can range from $200 to $1,200 per window. But prices vary remarkably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also provide door installations, which will make your project cost more.
Whether or not you pick energy-efficient windows is another factor that will affect the cost. These will typically cost more than other windows, but on the other hand, you can save about $572 a year on your energy bills in Oak Park.
Costs will also vary based on the material you want for your window frames. Aluminum frames are the least expensive. They're sturdy, light and maintenance-free, but offer poor insulation. Vinyl frames are somewhat expensive and offer good insulation. Composite frames made using wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They're also aesthetically pleasing and offer decent insulation for your home.
What Services do Window Installers Offer?
The first thing to ask yourself when planning on installing new windows is: Should you get a full-frame installation or a pocket installation?
A full-frame installation replaces the full window, including the windowsill, frame, trim and the window panes. As this type of installation is more involved, it will be more expensive than a pocket installation. A pocket installation entails replacing a window without taking out the whole frame, which tends to be less expensive than a full-frame installation.
If you're still trying to decide which kind of installation you should get, you can ask 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 Oak Park
EcoWatch reviews differ from other reviews, as we look at these companies through a sustainability lens. We've decided to assess the best window installers in Oak Park mostly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows have been shown to lower energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
Because this is a guide for Oak Park, we gave more points to companies that provide services to the city. There are other reputable providers that didn't make the list because they wouldn't be able to serve homeowners in Oak Park.
Work Quality
When picking new windows, the quality and variety of services can often play just as important of a role in overall efficiency 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 very important review factor is customer feedback. If the majority of customers don't have positive things to say about their experience with a certain window installation 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 points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed, windows are a serious investment, so you'll want to be certain that investment is well protected. Window installation companies that provide 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 a good track record in the industry. Window installers that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Oak Park, CA Window Replacement FAQs
What is the typical cost to install windows in a home?
The national average cost of installing a window is about $600 but can range from $200 to $1,200, depending on a variety of factors. The price is often dependent on the location of your property, the size of the window and the type and material of the window. Also, remember that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.
Which type of window is the best?
A window's energy efficiency is affected by a variety of factors, including the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are typically the most energy-efficient since they are certified by the U.S. Department of Energy.
Do I really have to use a window installation company?
Unless you have experience with home improvement projects and have the time needed to replace your own windows, we recommend hiring a professional. The process of installing windows 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 company is a faster, more efficient and much safer option.
How often do you need to replace your windows?
Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, they should probably be replaced. Apart from that, if your windows have any damage on them, or they have become difficult to open or close, they may need to be replaced.
