How Installing Energy-Efficient Windows in Glenview Saves You Money

When you switch to energy-efficient windows, you may see a few benefits, such as:

• Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out harmful UV rays, reducing fading of your furniture, carpet and other valuables.
• Save on energy bills: The Department of Energy estimates that heat gained or lost through windows makes up about 25-30% of residential energy use. Switching to energy-efficient windows can help reduce that number, which helps you save $295 a year on your bills.
• Decrease your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% when you install Energy Star certified windows. In Glenview, that’s about 449 pounds per year on average.
• Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes tend to have windows that are outdated, drafty or maybe even damaged in some way. Updating your windows could help increase the value of your property if you decide to sell.

Estimated Cost of Window Replacement in Glenview

Windows come in different styles, purposes and shapes, so costs and services will differ tremendously based on several factors. Below, we go over the typical cost and services that you’ll find from window installation companies.

How Much Do New Windows Cost?

Typically, Glenview homeowners can anticipate their replacement window installations to range from $250 to $1,200. The average cost sits at approximately $600. These figures are based on specific characteristics of your installation, such as number of windows, material, type, the location of your home, size and more.

Whether or not you want energy-efficient windows is another factor that will affect the cost. These will typically cost more than other windows, but on the other hand, you can save about $295 a year on your energy bills in Glenview.

We advise requesting free quotes from several window installation companies to find the right windows and the company that works best for you.

What Services do Window Installers Offer?

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

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 the existing frame, which makes pocket installations take less time and therefore cost less. However, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.

Your window installation company will be able to help you decide what’s best for your needs. In Glenview, the decision will mostly depend on how old your home is and if there’s any damage. Wood can decay if not properly maintained over the years, so it’s good to have a professional check on your frames and window sills.

How We Choose the Best Window Installers in Glenview

In our hunt to find the most reliable, eco-friendly window installers in Glenview, the EcoWatch team examined many companies before settling on these. We’ve decided to evaluate the best window installation companies in Glenview mostly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows have been shown to cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

Because this is a guide for Glenview, we paid more attention to companies that serve the city. There are certainly reputable providers that didn’t make the list because they wouldn’t be able to serve homeowners in Glenview.

Work Quality

When choosing new windows, the quality and range of services can often play just as important of a role in insulation and performance as the brand of window you get. We do rate window installers higher 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 things to say about their service from a certain company, you won’t see it featured on EcoWatch.

Cost

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

Warranty

As discussed previously, windows are a serious investment, so you’ll want to make sure that investment is well protected. Window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

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