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

Upgrading to energy-efficient windows can improve the comfort of your home and help you save on power bills. Here's more information on how switching out your windows could help you:

• Save on power bills: Since energy-efficient windows lower how much energy you need to heat or cool your home, the switch can help you save around $287 annually on your energy bills in East Hanover.
• Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
• Decrease your carbon footprint: By using less energy after upgrading to Energy Star certified windows, you’ll also be cutting your indirect greenhouse gas emissions by about 12%, according to Energy Star.
• 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 Older homes usually have windows that are outdated, leaky or maybe even damaged in some way. Upgrading your windows could help increase the value of your property if you decide to sell.

Estimated Cost of Window Replacement in East Hanover

Windows come in various shapes and sizes, so costs and services will differ remarkably. Here are the typical costs and the primary services that you can find from window installation companies.

How Much Do New Windows Cost?

The typical cost to install one window is about $600 but can range anywhere from $200 to $1,200. This is because the cost of window installations depend on a variety of factors specific to your home, such as the size, material and number of windows you need to install, as well as the location of your property.

It’s important to note that windows with the best efficiency may cost more initially but can save you hundreds of dollars by decreasing your energy bills. Investing in Energy Star certified windows can save East Hanover homeowners $287+ a year when replacing single-pane windows.

Another factor that affects the total cost is the material you pick for your frame. Aluminum frames are generally the least expensive and are sturdy and light, but they offer poor insulation. On the other hand, wood frames are the most expensive because they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.

What Services do Window Installers Offer?

Generally, there are two kinds of window installation services companies provide: full-frame and pocket installations.

Full-frame installations involve replacing the complete window, including the sill, frame and trim. You most likely need a full-frame installation when you want to change the style of your windows or your window has significant rot. Because these installations are more involved, they will raise the overall cost. A pocket installation entails replacing a window within the existing frame, which is usually cheaper than a full-frame installation.

Your window installation company will be able to help you figure out what’s best for your needs. In East Hanover, the decision will mostly depend on how old your windows are and if there’s any damage. Wood can decay if not maintained properly over the years, so it’s a good idea to have a professional examine your frames and window sills.
