How Installing Energy-Efficient Windows in Middletown Saves You Money

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

• Reduce your carbon footprint: You can reduce your carbon footprint by about 12% after you install Energy Star certified windows. In Middletown, that’s about 299 pounds per year on average.
• Protect your investment: The older your home is, the more likely it is that switching to energy-efficient 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 Older homes usually have windows that are outdated, leaky or potentially even damaged in some way.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.
• Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
• Save money on power bills: Upgrading to energy-efficient windows lowers your energy bills by about 12% because you need less energy.

Estimated Cost of Window Replacement in Middletown

Let’s take a look at the cost of window installation and the kinds of services offered by installers.

How Much Do New Windows Cost?

The typical cost to replace one window is about $600 but can range anywhere from $200 to $1,200. These amounts vary depending on the specifics of your installation, such as the location of your home, material, size, type, number of windows and more.

It’s important to remember that windows with the best efficiency may cost more initially but can save you hundreds of dollars by lowering your energy bills. Investing in Energy Star certified windows can save Middletown homeowners $301+ a year when replacing single-pane windows.

Asking for free quotes from several installers is the best way to figure out which one will work best for your budget.

What Services do Window Installers Offer?

The first question to ask yourself when considering a window replacement is: Do you need a full-frame installation or a pocket installation?

Full-frame installations involve replacing the full 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 rot or deterioration. Full-frame installations involve more time and labor and will increase overall costs. Pocket installations (or retrofits) involve replacing a window within its existing frame, which makes pocket installations take less time and therefore cost less. But, if the frame has any damage or rot, you should opt for a full-frame installation instead.

If you’re unsure which kind of window installation service you need, your installer should be able to assist you. Generally, the choice is based on factors such as the age and condition of the home, the type of building material, budget and time restrictions.
