How Installing Energy-Efficient Windows in Millstadt Saves You Money

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

  • Reduce your carbon footprint: You can reduce your carbon footprint by about 12% when you install Energy Star certified windows. In Millstadt, that's about 642 pounds per year on average.
  • Save money on power bills: Because energy-efficient windows lower the amount of energy needed to heat or cool your home, they can help you save about $316 annually on your energy bills in Millstadt.
  • Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Upgrading your windows can improve the insulation in your home and also help increase the value of your home if you decide to sell.
  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.

Estimated Cost of Window Replacement in Millstadt

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

How Much Do New Windows Cost?

Typically, homeowners in Millstadt can expect that most replacement window installations will cost between $250 and $1,200, with the most common installations sitting at about $600. But costs differ considerably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also offer door installations, which carry a higher price tag.

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

Another factor that influences the overall cost is the material you choose for your frame. Aluminum frames are typically the least expensive and are sturdy and relatively maintenance-free, but they provide poor insulation. On the other hand, wood frames are the most expensive, as they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.

What Services do Window Installers Offer?

The first step when planning a replacement is to figure out whether you need a full-frame or pocket installation.

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 extra materials, like 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 surrounding the window after a full-frame installation. Pocket installations (also known as retrofits) are when you replace a window while leaving the existing frame. Pocket installations are on the simpler end and will be less expensive, but you can't do this type of installment if you have any pre-existing rot or water damage.

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

How We Choose the Best Window Installers in Millstadt

In our search to find the most reliable, eco-friendly window installers in Millstadt, the EcoWatch Reviews team examined dozens of companies before deciding on these. We've assessed the best window replacement companies in Millstadt mostly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows can cut your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

Since this is a guide for Millstadt, we paid more attention to companies that provide services to the city. There are other reputable providers that didn't make our list because of the low odds that they would serve the average homeowner in Millstadt.

Work Quality

We're certain that you're looking for a company to do a great job installing windows. We've vetted each installer included on this list to make sure its technicians are well-qualified and that the company has gotten lots of positive customer feedback to vouch for its service.

Customer Reviews

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

Cost

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

Warranty

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

Years of Experience

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

Millstadt, IL Window Replacement FAQs

What is the typical cost to replace windows in a home?

The average cost to install one window ranges between $450 and $650. There are several factors that influence the cost, which include the materials used in designing the windows, how energy-efficient the windows are, local labor costs, your property's location, the number of windows and styles and sizes of windows.

What type of window is the most energy-efficient?

A window's energy efficiency depends on a variety of factors, including the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are often the most energy-efficient and are certified by the U.S. Department of Energy.

What do window installation companies do?

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

How long does window installation generally take?

Each window takes around 30 minutes to install based on the kind of window. However, the window installation can take two days or more if you have a lot of windows that need to be installed.

When is the best time of year to replace windows?
