Why you can trust EcoWatch
Whether you're doing home renovations or have windows that need repairs, windows play a vital role in conserving your home's electricity. The Department of Energy estimates that heat gained or lost through traditional or outdated windows could be responsible for about 30% of heating and cooling costs. In Bellefontaine Neighbors, where the electric bills are an average of $41 per month, that’s almost $$146 per year wasted.
That’s also bad for the environment because the extra energy required by leaky windows increases your carbon footprint.

How Installing Energy-Efficient Windows in Bellefontaine Neighbors Saves You Money
When you switch to energy-efficient windows, you may see several benefits, including:
- Save money on energy bills: The Department of Energy estimates that heat gained or lost through windows makes up around 25-30% of residential energy use. Installing energy-efficient windows can help reduce that number, which helps you save $376 a year on your bills.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, reducing fading of your furniture, carpet and other valuables.
- Protect your investment: When your home is on the older side, your windows could also be outdated or damaged. Keeping your windows up to date is an important part of maintaining your property and its real estate value.
- Decrease your carbon footprint: Since energy-efficient windows improve the insulation in your home, you can cut your indirect greenhouse gas emissions by about 12%, according to Energy Star.
Estimated Cost of Window Replacement in Bellefontaine Neighbors
When researching window installation, each company offers different services and costs. Let’s look at some average costs and services.
How Much Do New Windows Cost?
According to our research, the typical cost of replacing a single window is about $600. However, window installation costs can range from $200 to $1,200 per window. But prices differ considerably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also provide door installations and replacements, which will add extra costs to your project.
It’s important to keep in mind that windows with higher efficiency may cost more upfront but can save you hundreds of dollars via returns on your energy bills. Investing in Energy Star certified windows can save Bellefontaine Neighbors homeowners $376+ a year when replacing single-pane windows.
Another factor that affects the total cost is the material of the frame you pick. Aluminum frames are typically the least pricey and are sturdy and light, but they provide poor insulation. On the other hand, wood frames are the most expensive, as they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.
What Services do Window Installers Offer?
The first thing to ask yourself when planning on installing new windows is: Do you want a full-frame installation or a pocket installation?
Full-frame installations are usually done when you want to change the style of your windows or your window has a lot of rot or deterioration. With this service, your professionals will replace the entire window, including the frame, sill and trim. A pocket installation involves installing a new window within the frame that’s already there. So, instead of taking out the whole unit and rebuilding it, the window installer will just slide the replacement window (also called a retrofit or insert window) into the frame.
Your window installation company can help you figure out which type of installation you need.
