How Installing Energy-Efficient Windows in Clark Saves You Money

By switching to energy-efficient windows, you and your family can enjoy several benefits, such as:

• Decrease your carbon footprint: Reducing how much energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by 206 pounds per year on average.
• Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes usually have windows that are outdated, leaky or potentially even damaged in some way. Upgrading your windows could help increase the value of your home if you decide to sell.
• Save money on energy bills: The Department of Energy estimates that heat gained or lost through windows makes up about 25-30% of energy use in your home. Upgrading to energy-efficient windows can help lower that number, which helps you save more on your bills.
• Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out damaging UV rays, reducing fading of your furniture, carpet and other valuables.

Estimated Cost of Window Replacement in Clark

Each window installation company offers various services and has varying prices based on a few factors.

How Much Do New Windows Cost?

On average, Clark homeowners can anticipate their replacement window installations to range from $250 to $1,200. The most common installations sit at approximately $600. These estimates vary depending on specific characteristics of your installation, including type, material, size, number of windows, the location of your home and more.

With windows, efficiency is one of the most important factors for many homeowners. Windows with higher efficiency may cost more off the bat, but by increasing the efficiency of your home — especially during the summer and winter — they can provide many years of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Clark homeowners $290+ a year after replacing single-pane windows.

What Services do Window Installers Offer?

The first thing to ask yourself when planning a window installation is: Should you get a full-frame installation or a pocket installation?

A full-frame installation replaces the total window, including the sill, frame, trim and the window panes. Because this kind of installation is more involved, it will cost more than a pocket installation. A pocket installation involves replacing a window within the old frame. This means instead of taking out the whole window and rebuilding it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.

If you’re still trying to decide which type of installation you need, you can ask your provider and get their recommendation. The decision mostly is influenced by the age of your window frames and if there’s any damage present.
