How Installing Energy-Efficient Windows in Rock Island Saves You Money

By switching to energy-efficient windows, you can take advantage of several benefits, such as:

• Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes tend to have windows that are outdated, leaky or maybe even damaged in some way. Updating your windows could help raise the value of your home if you decide to sell.
• Save money on energy bills: Because energy-efficient windows reduce the amount of energy used to heat or cool your home, the switch can help you save around $323 annually on your energy bills in Rock Island.
• Reduce your carbon footprint: Because energy-efficient windows improve the insulation in your house, you can lower your carbon footprint by about 12%, according to Energy Star.
• Protect your valuables from fading: When you switch to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will be protected from fading because of their ability to filter out harmful UV rays.

Estimated Cost of Window Replacement in Rock Island

Each window installer provides varying services and has different costs depending on a few factors.

How Much Do New Windows Cost?

The national average cost to replace a single window is about $600 but can range from $200 to $1,200. This is because window installations depend on a variety of factors specific to your home, including the size, material and number of windows you need to replace, as well as where your property is located.

It’s important to remember that windows with higher efficiency may cost more upfront but can save you hundreds of dollars via returns on your energy bills. Investing in certified energy-efficient windows can save Rock Island homeowners $323+ a year when replacing single-pane windows.

The cost of your window installation will also vary depending on the type of window material you choose for the frames. Wood windows are generally the most expensive, but it depends on whether they are solid wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are more efficient.

What Services do Window Installers Offer?

There are generally two types of window installation services: full-frame and pocket installations.

Full-frame installations require replacing the entire window — the sill, frame, trim and all. These are most common when you want to change the style of your window or when it has significant deterioration. Full-frame installations are more comprehensive and will increase overall costs. A pocket installation entails replacing a window within the existing frame, which is generally cheaper than a full-frame installation.

If you’re not sure which window installation service you should get, your installer can help you out. Typically, the decision is based on factors such as the age and condition of the home, the type of building material, budget and time restrictions.
