How Installing Energy-Efficient Windows in West Chicago Saves You Money

By switching to energy-efficient windows, you can benefit in several ways, such as:

• 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 fading of your furniture, carpet and other valuables.
• Save money on electricity bills: The Department of Energy estimates that heat gained or lost via windows makes up around 25-30% of energy use in your home. Switching to energy-efficient windows can help decrease that number, which helps you save some money on your bills.
• Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% after you install Energy Star certified windows. In West Chicago, that’s about 449 pounds per year on average.
• Protect your investment: If your home is on the older side, your windows are most likely outdated. Updating your windows can improve the insulation in your home and also help increase the value of your house if you decide to sell.

Estimated Cost of Window Replacement in West Chicago

Windows come in different shapes and sizes, so costs and services will vary remarkably. Here are the average costs and services that you’ll find from window installation companies.

How Much Do New Windows Cost?

According to our market research, the national average cost of replacing a single window is around $600. However, window replacement costs can range from $200 to $1,200 a window. These numbers are based on specific characteristics of your installation, including the location of your home, size, number of windows, 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 Energy Star certified windows can save West Chicago homeowners $300+ a year when replacing single-pane windows.

What Services do Window Installers Offer?

The first thing to ask yourself when planning on installing new windows is: Do you need a full-frame installation or a pocket installation?

Full-frame installations require replacing the whole window — the sill, frame, trim and all. These are most common when you want to change the style of your window or when it has significant deterioration. Full-frame installations require more time and labor and will increase overall costs. Pocket installations (or retrofits) entail installing a new window within its existing frame, which makes pocket installations less labor-intensive and costly. However, if the frame has any damage or rot, you should opt for a full-frame installation instead.

If you’re not sure which window installation service you need, your installer can advise you. In general, the decision is based on factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in West Chicago

The EcoWatch Reviews team differs from most reviewers because we look at these companies through a sustainability lens. Along with energy efficiency, we evaluated window companies all across the state and assigned rankings using the following methodology:

Service Area

Because this is a guide for West Chicago, we only included companies that cover the city. There are other reputable providers that didn’t make the list because they wouldn’t be able to serve homeowners in West Chicago.

Work Quality

We’re willing to bet that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each installer on this list to ensure its contractors are well-qualified and that the company has received lots of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed patterns in recent customer feedback to determine the companies with the most customer satisfaction. Customer satisfaction may be the most important factor, as it reflects the quality of services across most other categories, including professionalism, cost, warranty, quality of parts, quality of installation and more.

Cost

This one is a give-and-take: similar to other services, cheap window installation companies may not provide the highest quality service. On the other hand, we want to ensure we’re highlighting companies that offer a spectrum of price and financing options so they’re accessible to most homeowners.

Warranty

As discussed previously, windows are a hefty investment, so you’ll want to be certain that investment is well protected. Window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Last but not least, we like to see companies that have a proven 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.
