How Installing Energy-Efficient Windows in Byron Saves You Money
Switching to energy-efficient windows can improve the comfort of your home and help you save on energy bills. Here are more ways switching out your windows could help you:
- Save on energy bills: Switching to energy-efficient windows lowers your energy bills by about 12% since you use less energy.
- Protect your investment: Upgrading your windows is an important part of maintaining your property and its value, especially if you have an older home.
- Decrease your carbon footprint: Decreasing the amount of energy you use also lowers your carbon emissions. You could reduce it by about 449 pounds.
- Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
Estimated Cost of Window Replacement in Byron
Windows come in various shapes, purposes and styles, so costs and services will vary greatly depending on several factors. Below, we detail the typical cost and services that you can get from window installation companies.
How Much Do New Windows Cost?
Typically, Byron homeowners can anticipate their window replacements to range from $250 to $1,200. The average cost sits at about $600. These numbers vary depending on specific characteristics of your installation, including material, type, number of windows, the location of your home, size and more.
It's also worth bearing in mind that energy-efficient windows will cost more initially, but Energy Star predicts that switching out the windows on your Byron home can mean an average energy savings of $236 to $319 a 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 switching to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
We advise requesting free quotes from several window companies to find the right windows and the company that works best for you.
What Services do Window Installers Offer?
The first step when planning an installation is to decide whether you should get a full-frame or pocket installation.
Full-frame installations are usually recommended when you want a new style or your window has significant rot. With this service, your professionals will replace the whole window, including the frame, trim and sill. A pocket installation entails replacing a window within the old frame. So, instead of removing the whole window and reinstalling it, the window installer will just put the replacement window (also called a retrofit or insert window) into the frame.
If you're not sure which window installation service you need, your installer should be able to advise you. In general, the choice is based on factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Byron
In our search to make your home improvements easier and more eco-friendly in Byron, the EcoWatch team chose the above companies as the top window installation companies in the city. We've evaluated the top window installation companies in Byron mostly based on their energy efficient offerings, as it's what's best for the environment and for you as a homeowner. Energy Star certified windows have been shown to reduce your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
Since this is a guide for Byron, we gave more points to companies that provide services to the city. There are other reputable providers that didn't make our list because of the low odds that they would serve the average homeowner in Byron.
Work Quality
When selecting new windows, the quality and variety of services often plays just as important of a role in insulation and performance as the type of window you opt for. We do give window installers higher marks if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
Another self-explanatory yet super important review factor is customer feedback. If the majority of customers don't have good feedback about their experience with a certain company, it won't be featured on EcoWatch.
Cost
This one is a give-and-take: similar to other services, cheap window installers won't always provide the most quality service. Still, we want to ensure we're highlighting companies that offer a spectrum of price and financing options so they're accessible to most homeowners.
Warranty
As discussed previously, windows are a serious investment, so you'll want to make sure that investment is protected. Window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of Byron's climate, homeowners will want to mitigate water damage, low efficiency and rot. We factored in local experience to reflect the ability of Byron window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Byron, IL Window Replacement FAQs
How much does window installation cost?
The typical cost to replace a single window ranges from $450 to $650. There are a variety of factors that affect the cost, including local labor costs, how energy-efficient the windows are, your property's location, styles and sizes of windows, the number of windows and the materials used in designing the windows.
What are the most common kinds of replacement windows?
There are various types of windows you can get for your home, such as bay windows, casement windows, double-hung and single-hung windows, transom windows, slider windows, awning windows and picture windows.
Do you really need to use a window installation company?
Unless you have home repair skills and have all of the necessary tools to replace your own windows, we recommend hiring a professional. The window installation process is complicated and can take anywhere from four to six hours for a single window. Although it's tempting to try to do it yourself to save money, hiring a professional is a faster, more efficient and safer alternative.
When is the best time of year to replace windows?
Though you can install windows any time of year, warmer weather is usually better for installing replacement windows. Additionally, it shouldn't be raining, because rain can make the installation more difficult.
Should I replace my windows all at once?
If your windows are more than 20 years old, it's probably time to replace all of them. By that point, they are often less efficient, draftier and/or more damaged than new windows. Doing your windows all at the same time will involve less paperwork and less stress.
