How Installing Energy-Efficient Windows in Willowbrook Saves You Money

Energy-efficient windows can benefit you in several ways. Here are some reasons you may want to consider making the switch:

  • Protect your valuables from fading: When you switch to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will be protected from fading due to their ability to filter out harmful UV rays.
  • Reduce your carbon footprint: You can reduce your carbon footprint by about 12% once you install Energy Star certified windows. In Willowbrook, that’s about 117 pounds per year on average.
  • Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes usually have windows that are outdated, drafty or maybe even damaged in some way.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 home if you decide to sell.
  • Save on power bills: Since energy-efficient windows reduce how much energy you need to heat or cool your home, the switch can help you save around $509 annually on your energy bills in Willowbrook.

Estimated Cost of Window Replacement in Willowbrook

Each window replacement company offers varying services and has different price points depending on a few factors.

How Much Do New Windows Cost?

Even though the national average cost to install a single window is about $600, it can range anywhere from $200 to $1,200. How much it will cost depends on several factors, like the location of your home, size, type, number of windows, material and more.

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

Requesting free quotes from multiple installers is the best way to figure out which one will work best for your budget.

What Services do Window Installers Offer?

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

Full-frame installations entail replacing the total window, including the trim, frame and sill. You most likely need a full-frame installation when you want a new style or your window has considerable damage. Because these installations are more involved, they will increase overall costs. Pocket installations (or retrofits) involve installing a new window within the existing frame, which makes pocket installations less labor-intensive and costly. But, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.

If you’re unsure which kind of window installation service you should get, your installer can help you out. In general, the decision depends 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 Willowbrook

EcoWatch reviews differ from most reviews since we assess these companies through a sustainability lens. We have decided to assess the top window replacement companies in Willowbrook primarily based on energy efficiency, as it’s what’s best for the environment and for you as a homeowner. Energy Star certified windows have been shown to reduce your 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 Willowbrook, we gave more points to companies that provide services to the city. There are certainly reputable providers that didn’t make our list because they wouldn’t be able to serve homeowners in Willowbrook.

Work Quality

We’re willing to bet that you’re looking for a company to do a great job installing windows. We’ve vetted each company featured in our guide to ensure its contractors are well-qualified and that the company has gotten plenty of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed patterns in recent online reviews to determine the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction might be the most important factor, as it indicates the quality of services across most other categories, including quality of installation, professionalism, quality of parts, warranty, cost and more.

Cost

Cheaper windows don’t necessarily mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing the prices of providers, we awarded higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

As discussed, windows are a significant investment, so you’ll want to make sure that investment is protected. Window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

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