How Installing Energy-Efficient Windows in Newtown Saves You Money

Switching to energy-efficient windows can help improve the comfort of your home and help you save on power bills. Here are more ways switching out your windows could benefit you:

• Protect your investment: If you have an older home, your windows are most likely outdated. Updating your windows can make your home more comfortable and also help raise the value of your house if you decide to sell.
• Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.
• Decrease your carbon footprint: In Newtown, you can lower your indirect greenhouse gas emissions by about 147 pounds per year once you install energy-efficient windows.
• Save on power bills: Once you upgrade to energy-efficient windows, you can expect a reduction in your bills by about 12% since you’ll require less energy to heat or cool your home.

Estimated Cost of Window Replacement in Newtown

When researching window installation, each company provides varying services and prices. Let’s go over some average costs and services.

How Much Do New Windows Cost?

Generally, homeowners in Newtown can anticipate that most window installations will range from $250 to $1,200, with the average cost at about $600. These amounts vary depending on the specifics of your installation, including type, material, the location of your home, size, number of windows and more.

With windows, efficiency is the most important factor for most homeowners. High efficiency windows may cost more initially, 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 Newtown homeowners $441+ a year after replacing single-pane windows.

We advise requesting free quotes from multiple window companies to find the one that works best for you.

What Services do Window Installers Offer?

In general, there are two types of window replacement services you can get: full-frame and pocket installations.

A full-frame installation replaces the entire window, including the windowsill, frame, trim and the window panes. Because this kind of installation requires more time, it will be more expensive than a pocket installation. A pocket installation means replacing a window within the existing frame, which is generally less expensive than a full-frame installation.

If you’re still debating which kind of installation to get, you can ask your installer and get their advice. The choice mostly depends on the age of your window frames and if there’s any damage.
