How Installing Energy-Efficient Windows in Zion Saves You Money

By upgrading to energy-efficient windows, you and your family can benefit in several ways, including:

• Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
• 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 Older homes tend to have windows that are outdated, drafty or maybe even damaged in some way.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 raise the value of your property if you decide to sell.
• Save money on power bills: The Department of Energy estimates that heat gained or lost through windows makes up around 25-30% of household energy use. Switching to energy-efficient windows can help reduce that amount, which helps you save $298 a year on your bills.
• Decrease your carbon footprint: Because energy-efficient windows improve the insulation in your home, you can cut your indirect greenhouse gas emissions by about 12%, according to Energy Star.

Estimated Cost of Window Replacement in Zion

When looking into window installation, each company offers different services and prices. Let’s go over some average costs and services.

How Much Do New Windows Cost?

Although the typical cost of installing one window is around $600, it can range anywhere from $200 to $1,200. This is because of the fact that the cost of window installations are based on several factors specific to your home, such as the size, material and number of windows you need to replace, as well as where your property is located.

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

How much your window installation costs will also vary based on the kind of material you choose for the frames. Wood windows are usually the most expensive, but it depends on whether they are 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are shown to be more efficient.

What Services do Window Installers Offer?

The first step when planning an installation is to decide whether you need a full-frame or pocket installation.

Full-frame installations require replacing the whole window — the sill, frame, trim and all. These are typically done when you want a new style for your windows or when it has significant damage. Full-frame installations require more time and labor and will increase overall costs. A pocket installation involves installing a new window within the frame that’s already there. This means instead of tearing out the whole unit and rebuilding it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.

Your window installer can help you decide which type of installation you need.
