How Installing Energy-Efficient Windows in New Castle Saves You Money

Energy-efficient windows can benefit you in several ways. Here are some reasons you may want to take the plunge and make the switch:

• Reduce your carbon footprint: Decreasing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 286 pounds.
• Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
• Save money on power bills: The Department of Energy estimates that heat gained or lost through windows makes up about 25-30% of energy use in your home. Switching to energy-efficient windows can help decrease that amount, which helps you save $313 a year on your bills.
• Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes tend to have windows that are outdated, leaky or maybe even damaged in some way. Updating your windows could help increase the value of your home if you decide to sell.

Estimated Cost of Window Replacement in New Castle

Windows come in all shapes and sizes, so costs and services will vary tremendously. Here are the average costs and services that you can find from window installers.

How Much Do New Windows Cost?

Generally, New Castle homeowners can anticipate their window installations to range from $250 to $1,200. The average cost sits at about $600. This is because window installations depend on several factors specific to your home, like the size, material and number of windows you need to install, as well as the location of your property.

It’s also worth bearing in mind that energy-efficient windows will typically cost more upfront, but Energy Star estimates that switching out the windows on your New Castle home translates to an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. The amount of money you’ll save by upgrading to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.

Another factor that influences the total cost is the material you choose for your frame. Aluminum frames are typically the least pricey and are sturdy and relatively maintenance-free, 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?

There are typically two kinds of window replacement services: full-frame and pocket installations.

Full-frame installations involve replacing the total window, including the sill, frame and trim. Full-frame installations are necessary when you want to change the style of your windows or your window has noticeable rot. These installations are more involved and will increase the total cost. 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 type of installation you should get, you can ask your provider and get their recommendation. The decision mostly depends on the age of your window frames and if there’s any damage present.
