How Installing Energy-Efficient Windows in Hazelwood Saves You Money

There are several benefits of upgrading to energy-efficient windows. A few reasons you may want to consider making the switch include the following:

• 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.
• Save on electricity bills: The Department of Energy estimates that heat gained or lost via windows accounts for around 25-30% of residential energy use. Upgrading to energy-efficient windows can help decrease that number, which helps you save more on your bills.
• Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% when you install Energy Star certified windows. In Hazelwood, that’s about 763 pounds per year on average.
• Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, reducing fading of your furniture, carpet and other valuables.

Estimated Cost of Window Replacement in Hazelwood

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

How Much Do New Windows Cost?

The typical cost to replace one window is about $600 but can range from $200 to $1,200. These numbers vary based on specific characteristics of your installation, including the location of your home, material, type, size, number of windows and more.

Bear in mind that energy-efficient windows may cost more, but Energy Star predicts the upgrade will save you between $101 and $583 a year when replacing single-pane windows and between $27 and $197 a year when you install double-pane, clear glass windows. These savings vary based on your local climate, energy rates and individual home characteristics.

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

What Services do Window Installers Offer?

In regard to window installations, in general there are two types that your provider will have: full-frame and pocket installations.

A full-frame installation is a total window replacement. This service involves removing the old window, the windowsill, and the exterior and interior trim. It also involves other materials, such as insulation and drip edges, which raise the total cost of the project. Also worth noting: you may have to touch up the paint around the window after a full-frame installation. A pocket installation entails installing a new window without replacing the frame. This means instead of taking out the whole unit and rebuilding it, the window installer will just put the replacement window (also called a retrofit or insert window) into the frame.

If you’re not sure which window installation service you should get, your installer can advise you. Generally, the decision 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 Hazelwood

In our hunt to make your home improvements easier and more eco-friendly in Hazelwood, the EcoWatch Reviews team examined many companies before landing on these. We’ve evaluated the top window replacement companies in Hazelwood mostly based on their energy efficient offerings, 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

Since this is a guide for Hazelwood, we only included companies that cover the city. There are certainly other reputable providers that didn’t make the cut because of the low odds that they would serve the average homeowner in Hazelwood.

Work Quality

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

Customer Reviews

We analyzed trends in recent online reviews to determine the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction may be the factor we place the most value on, as it reflects the quality of services across most other categories, including quality of installation, warranty, quality of parts, cost, professionalism and more.

Cost

This one is a give-and-take: as with other services, cheap window companies may not provide the most quality service. On the other hand, we want to make sure we’re highlighting companies that provide a range of price and financing options so they’re accessible to most homeowners.

Warranty

As discussed, windows are a serious investment, so you’ll want to make sure that investment is well protected. Window installation companies that provide 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 a proven track record in the industry. Window installers that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
