How Installing Energy-Efficient Windows in St Charles Saves You Money

There are several benefits of switching to energy-efficient windows. Some reasons you may want to consider making the change are the following:

• Protect your valuables from fading: When you switch to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will be protected from fading due to their ability to filter out harmful UV rays.
• Save money on energy bills: Once you upgrade to energy-efficient windows, you can expect a reduction in your bills by about 12% because you'll need less energy to heat or cool your home.
• Reduce your carbon footprint: Since energy-efficient windows improve the insulation in your house, you can lower your indirect greenhouse gas emissions by about 12%, according to Energy Star.
• Protect your investment: If your home is on the older side, your windows are most likely outdated. Upgrading your windows can improve the insulation in your home and also help increase the value of your house if you decide to sell.

Estimated Cost of Window Replacement in St Charles

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

How Much Do New Windows Cost?

Typically, homeowners in St Charles can anticipate that most window installations will range from $250 to $1,200, with the average cost at about $600. How much it will cost you varies based on several factors, like material, size, the location of your home, type, number of windows and more.

It's important to remember that windows with the best efficiency may cost more upfront but can save you hundreds of dollars by lowering your energy bills. Investing in Energy Star certified windows can save St Charles homeowners $382+ a year when replacing single-pane windows.

The cost of your window installation will also vary based on the kind of material you choose for the frames. Wood windows are usually the most expensive, though it depends if they are 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are shown to be more efficient.

What Services do Window Installers Offer?

When considering window installations, there are generally two types that your installer will have: full-frame and pocket installations.

Full-frame installations involve replacing the full window, including the frame, trim and sill. You most likely need a full-frame installation when you want to change the style of your windows or your window has considerable rot. Full-frame installations are more involved and will raise the total cost. A pocket installation entails replacing a window within the existing frame, which tends to be cheaper than a full-frame installation.

Your window replacement company will be able to help you decide what's best for your needs. In St Charles, the decision will mostly be based on the age of your windows and if there's any damage. Wood can decay if not maintained properly over the years, so it's good to have a professional check your frames and window sills.
