How Installing Energy-Efficient Windows in Prospect Heights Saves You Money

Energy-efficient windows can benefit you in several ways. Here are some reasons you may want to take the plunge and make the switch:

  • 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. Installing energy-efficient windows can help decrease that number, which helps you save some money on your bills.
  • Protect your investment: When you have an older home, your windows could also be outdated or damaged. Upgrading your windows is an important part of maintaining your property and its value.
  • Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
  • More efficient energy use in your home: In Prospect Heights where the winters can get very cold, energy-efficient windows reduce the amount of heat that is lost through your windows, making it easier to keep your house warm.

Estimated Cost of Window Replacement in Prospect Heights

Windows come in various shapes and sizes, so costs and services will vary remarkably. Here are the average costs and the primary services that you'll find from window installers.

How Much Do New Windows Cost?

The average cost to replace one window is about $600 but can range anywhere from $200 to $1,200. How much it will cost you depends on several factors, including type, material, size, the location of your home, number of windows and more.

It's important to remember that windows with the best efficiency may cost more initially but can save you hundreds of dollars via returns on your energy bills. Investing in certified energy-efficient windows can save Prospect Heights homeowners $295+ a year when replacing single-pane windows.

How much your window installation costs will also vary based on the type of window material you choose for the frames. Wood windows are typically the most expensive, though it depends if they are completely wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are more efficient.

What Services do Window Installers Offer?

There are generally two types of window replacement services: full-frame and pocket installations.

A full-frame installation is a total window replacement. It involves taking out the old window, the sill, and the exterior and interior trim. It also involves extra materials, including insulation and drip edges, which raise the overall cost of the project. It's also worth noting that you may have to touch up the paint around the window after a full-frame installation. A pocket installation means replacing a window within the existing frame, which is usually less expensive than a full-frame installation.

Your window installation company will be able to help you understand what's best for your needs. In Prospect Heights, the decision will mostly depend on the age of your windows and if there's any damage. Wood can decay if not maintained properly over the years, so it's good to have a professional check your frames and window sills.

How We Choose the Best Window Installers in Prospect Heights

EcoWatch is different from other reviewers, as we're examining these companies through a sustainability lens. We have assessed the best window installation companies in Prospect Heights mainly based on energy efficiency, as it's the most sustainable option and the best one for homeowners. Energy-efficient windows can lower energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

Because this is a guide for Prospect Heights, we gave more points to companies that serve the city. There are certainly other reputable providers that didn't make our list because they wouldn't be able to serve homeowners in Prospect Heights.

Work Quality

When selecting new windows, the quality and breadth of services can often play just as important of a role in insulation and performance as the brand of window you opt for. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

We analyzed patterns in recent online reviews to determine the companies with the most consistent customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it indicates the quality of services across most other categories, including cost, warranty, quality of installation, quality of parts, professionalism and more.

Cost

Cheaper windows don't necessarily mean better windows, but we know many of our readers try to keep costs as low as possible. When analyzing the prices of providers, we gave higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

Protecting your investment in new windows is important. That's why window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Lastly, we like to see companies that have been in the industry for a while. Window installers that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.

Prospect Heights, IL Window Replacement FAQs

How much does a window install cost?

The national average cost to install a single window is around $600 but can range between $200 and $1,200, depending on a few different factors. The price is often influenced by the type and material of the window, the location of your property and the size of the window. Also, remember that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.

What type of window is the most energy-efficient?

Generally, double-pane windows are more efficient than single-pane windows and windows that do not open will be more efficient than windows that do. If you want to be sure you'll have the most energy-efficient windows, look for models with the blue Energy Star certification — this means they're certified energy-efficient by the U.S. Department of Energy.

What do window installers do?

Window installers cover the entire process — from replacing old windows with new ones to cleaning up after the installation. In addition, a lot of companies offer window manufacturing, customization and repairs.

How often do you need to replace windows?

Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, then they should probably be replaced. Apart from that, if your windows have damage anywhere on them, or they have become difficult to open or close, they may be in need of replacement.
