How Installing Energy-Efficient Windows in Dardenne Prairie Saves You Money

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

• Save on energy bills: The Department of Energy estimates that heat gained or lost through windows makes up about 25-30% of household energy use. Upgrading to energy-efficient windows can help lower that number, which helps you save more on your bills.
• Protect your valuables from fading: When you upgrade 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.
• Protect your investment: Upgrading your windows is an important part of maintaining your property and its real estate value, especially if you have an older home.
• Decrease your carbon footprint: By using less energy once you upgrade to energy-efficient windows, you’ll also be cutting your indirect greenhouse gas emissions by about 12%, according to Energy Star.

Estimated Cost of Window Replacement in Dardenne Prairie

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

How Much Do New Windows Cost?

The national average cost to replace a single window is about $600 but can range from $200 to $1,200. These amounts vary depending on the specifics of your installation, such as the location of your home, size, type, material, number of windows and more.

With windows, efficiency is the most important factor for many homeowners. Efficient windows may cost more upfront, but by increasing the efficiency of your home — especially during the summer and winter — they can give you decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Dardenne Prairie homeowners $382+ per year after replacing single-pane windows.

We advise 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?

In general, there are two kinds of window installation services companies offer: full-frame and pocket installations.

Full-frame installations involve replacing the entire window — the sill, frame, trim and all. These are most common when you want a new style for your windows or when it has significant damage. Full-frame installations involve more time and labor and will increase overall costs. A pocket installation means replacing a window without taking out the entire frame, which is generally less expensive than a full-frame installation.

Your window installation company will be able to advise you on the best type for your project. In Dardenne Prairie, the decision will mostly be based on how much damage there is currently and the age of your existing frames.

How We Choose the Best Window Installers in Dardenne Prairie

EcoWatch reviews differ from most reviews because we’re examining these companies through a sustainability lens. We’ve assessed the best window replacement companies in Dardenne Prairie primarily based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows can lower 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 Dardenne Prairie, we only included companies that cover the city. There are certainly other reputable providers that didn’t make the cut because they wouldn’t be able to serve homeowners in Dardenne Prairie.

Work Quality

When selecting new windows, the quality and breadth of services often plays just as important of a role in insulation and performance as the brand of window you get. We do give window installers more points if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

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

Cost

Cheaper windows certainly don’t mean better windows, but we know many of our readers would like 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

As discussed previously, windows are a hefty investment, so you’ll want to be certain that investment is well protected. Window installation companies that offer 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 a while. Window installation companies that have more experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
