How Installing Energy-Efficient Windows in East Hampton Saves You Money

When you switch to energy-efficient windows, you may see some benefits, including:

• Decrease your carbon footprint: In East Hampton, you can lower your indirect greenhouse gas emissions by about 147 pounds per year when you switch to energy-efficient windows.
• Protect your investment: If you have a relatively old home, your windows are most likely in need of replacement. Updating your windows can make your home more comfortable and also help increase the value of your house if you decide to sell.
• Save money on electricity bills: After you switch to energy-efficient windows, you can see a reduction in your bills by about 12% since you’ll require less energy to heat or cool your home.
• 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 East Hampton

Each window replacement company provides various services and has varying prices based on a few factors.

How Much Do New Windows Cost?

Even though the typical cost of replacing a single window is around $600, it can range anywhere from $200 to $1,200. 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 installers also provide door replacements, which will make your project cost more.

With windows, efficiency is the most important factor for many homeowners. Efficient 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 East Hampton homeowners $403+ per year after replacing single-pane windows.

What Services do Window Installers Offer?

The first step when considering a window installation is to think about whether you want a full-frame or pocket installation.

A full-frame installation replaces the complete window, including the windowsill, frame, trim and the window panes. As this type of installation requires more time and labor, it will cost more than a pocket installation. Pocket installations (or retrofits) involve replacing a window within its existing frame, which makes pocket installations less labor-intensive and costly. However, if the frame has any damage or rot, you will likely need a full-frame installation instead.

Your window installation company can help you figure out which type of installation you need.
