How Installing Energy-Efficient Windows in Carpentersville 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 include the following:

• Protect your valuables from fading: When you switch to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will fade less because of their ability to filter out damaging UV rays.
• Reduce your carbon footprint: In Carpentersville, you can reduce your indirect greenhouse gas emissions by about 449 pounds per year once you install energy-efficient windows.
• 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 Older homes usually have windows that are outdated, drafty or maybe even damaged in some way. Upgrading your windows could help increase the value of your property if you decide to sell.
• Save money on power bills: The Department of Energy estimates that heat gained or lost via windows accounts for about 25-30% of household energy use. Switching to energy-efficient windows can help lower that number, which helps you save $297 a year on your bills.

Estimated Cost of Window Replacement in Carpentersville

Windows come in varying shapes, styles and purposes, so costs and services will differ greatly depending on several factors. Below, we describe the typical cost and services that you’ll find from window replacement companies.

How Much Do New Windows Cost?

According to our market research, the national average cost of replacing a single window is about $600. However, window replacement costs can range from $200 to $1,200 per window. This is because window installations depend on several factors specific to your home, such as the size, material and number of windows you need to replace, as well as where your property is located.

Bear in mind that energy-efficient windows may have a higher price, but Energy Star estimates the upgrade will save you between $101 and $583 per year when installing single-pane windows and between $27 and $197 per year when replacing double-pane, clear glass windows. Your savings will vary depending on your local climate, energy rates and individual home characteristics.

We recommend requesting free quotes from multiple window installers to find the right windows and the company that works best for you.

What Services do Window Installers Offer?

The first step when planning a window replacement is to figure out whether you need a full-frame or pocket installation.

A full-frame installation replaces the full window, including the windowsill, frame, trim and the window panes. Because this type of installation requires more time, it will cost more than a pocket installation. Pocket installations (also known as retrofits) are when you replace a window without replacing the frame. Pocket installations are simpler and won’t carry as large a bill, but you can’t do this kind of installment if you have any pre-existing rot or water damage.

If you’re not sure which window installation service you should get, your installer should be able to advise you. Typically, the choice is based on factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Carpentersville

EcoWatch reviews are different from other reviews, as we’re examining these companies through a sustainability lens. We have evaluated the best window installers in Carpentersville mostly based on their energy efficient offerings, as it’s what’s best for the environment and for you as a homeowner. Energy-efficient windows have been shown to 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 pretty self-explanatory, but we’ve chosen to highlight window installation companies that serve the Carpentersville area so you can find the right window installation company near you.

Work Quality

When selecting new windows, the quality and variety of services often plays just as important of a role in overall efficiency and performance as the type of window you opt for. We do give window installers more points if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

Customer feedback is another super important review factor. If most customers don’t have positive feedback about their service from a certain company, it won’t be featured on EcoWatch.

Cost

This one is a give-and-take: similar to most services, cheap window installers may not provide the highest quality service. On the other hand, we want to make sure we’re highlighting companies that provide a variety 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 be certain that investment is well protected. Window installation companies that have 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 been in the industry for quite some time. Window installers that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
