Why you can trust EcoWatch
Whether you're doing renovations or have windows that need repairs, windows play a vital role in conserving electricity in your home. If you have outdated, drafty windows, your AC or heating system could be working extra hard to heat or cool your home. This means spending more on electric bills.
That’s also bad for the environment, as the additional energy required by drafty windows increases your carbon footprint.
Efficient windows are especially important in Godfrey, where the temperature varies throughout the year. According to Energy Star, switching to energy-efficient windows can save the average homeowner up to $313 each year.

How Installing Energy-Efficient Windows in Godfrey Saves You Money
By upgrading to energy-efficient windows, you and your family can benefit in several ways, including:
- Reduce your carbon footprint: In Godfrey, you can lower your indirect greenhouse gas emissions by about 642 pounds per year once you install energy-efficient windows.
- Protect your investment: If your home is on the older side, your windows are most likely outdated.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 property if you decide to sell.
- Save money on energy bills: Since energy-efficient windows decrease how much energy you need to heat or cool your home, they can help you save about $313 annually on your energy bills in Godfrey.
- 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.
Estimated Cost of Window Replacement in Godfrey
Windows come in different shapes, purposes and styles, so costs and services will vary greatly based on your project. Below, we describe the average cost and services that you’ll find from window installation companies.
How Much Do New Windows Cost?
Typically, Godfrey homeowners can expect their window replacements to range from $250 to $1,200. The most common installations sit at approximately $600. These amounts vary depending on specific characteristics of your installation, like material, number of windows, type, size, the location of your home and more.
Whether or not you opt for energy-efficient windows is another factor that will determine the cost. These will usually cost more than other windows, but on the other hand, you can save about $313 a year on your energy bills in Godfrey.
Another factor that affects the total cost is the material of the frame you select. Aluminum frames are usually 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 and cost somewhere between the other two.
What Services do Window Installers Offer?
The first thing to ask yourself when planning a window installation is: Should you get a full-frame installation or a pocket installation?
Full-frame installations are necessary when you want a new style or your window has a lot of rot or deterioration. With this service, your installers will replace the total window, including the sill, trim and frame. Pocket installations (also known as retrofits) are when you replace a window while leaving the old frame. Pocket installations are on the simpler end and won’t carry as large a bill, but you can’t do this kind of installment if you have any pre-existing rot or water damage.
Your window installation company can help you figure out which type of installation you need.
