How Installing Energy-Efficient Windows in Du Page Saves You Money

There are quite a few perks of switching to energy-efficient windows. A few reasons you may want to consider making the switch are the following:

• Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes usually have windows that are outdated, leaky or maybe even damaged in some way. Upgrading your windows could help increase the value of your property if you decide to sell.
• Decrease your carbon footprint: Decreasing how much energy you use also lowers your carbon emissions. You could reduce it by about 449 pounds.
• Save money on power bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of residential energy use. Installing energy-efficient models can help decrease how much energy is used in your home, therefore saving you about 12% more on your bills.
• Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.

Estimated Cost of Window Replacement in Du Page

How Much Do New Windows Cost?

The national average cost to replace a single window is about $600 but can range anywhere from $200 to $1,200. These estimates vary based on specific characteristics of your installation, like material, size, number of windows, type, the location of your home and more.

It’s also worth bearing in mind that energy-efficient windows will usually cost more upfront, but Energy Star predicts that upgrading the windows on your Du Page home can mean an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 per year for double-pane windows.

Asking for free quotes from multiple installers is the best way to find out which one is right for you.

What Services do Window Installers Offer?

The first thing to ask yourself when planning a window installation is: Do you want a full-frame installation or a pocket installation?

Full-frame installations involve replacing the full window, including the frame, sill and trim. Full-frame installations are necessary when you want to change the style of your windows or your window has noticeable damage or rot. These installations are more involved and will raise the overall cost. A pocket installation involves replacing a window within the existing frame, which is generally less expensive than a full-frame installation.

Your window installation company will be able to help you choose what’s best for your needs. In Du Page, the decision will mostly depend on the age of your home and if there’s any moisture damage. Wood can decay if it’s not maintained properly over the years, so it’s a good idea to have a professional evaluate your frames and window sills.

How We Choose the Best Window Installers in Du Page

In our hunt to find the most reliable, eco-friendly window installers in Du Page, the EcoWatch team chose the above companies as the best window installation companies in the city. We’ve assessed the best window installation companies in Du Page primarily based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows can lower electricity 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 Du Page so you can find a quality window installation company near you.

Work Quality

When installing new windows, the quality and breadth of services can often play just as important of a role in overall efficiency and performance as the brand you choose. We do give window installers higher marks if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

We analyzed trends in recent customer feedback to determine the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it reflects the quality of services across most other categories, including professionalism, cost, quality of parts, quality of installation, warranty and more.

Cost

This one is a give-and-take: as with other services, cheap window installers won’t always provide the highest quality service. Still, we want to make sure we’re highlighting companies that provide 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 have lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Because of Du Page’s climate, homeowners will want to mitigate low efficiency, rot and water damage. We factored in local experience to reflect the ability of Du Page window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
