How Installing Energy-Efficient Windows in Byron Saves You Money
Energy-efficient windows can offer benefits in more than one way. Here are a few reasons you may want to think about making the switch:
- Protect your valuables from fading: When you switch to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will fade less because of their ability to filter out harmful UV rays.
- Save on power bills: The Department of Energy estimates that heat gained or lost through windows makes up about 25-30% of energy use in your home. Switching to energy-efficient windows can help reduce that amount, which helps you save $309 a year on your bills.
- Protect your investment: When you have an older home, your windows could also be outdated or leaky. Upgrading your windows is an important part of maintaining your property and its real estate value.
- Better temperature control in your home: When you reside in a city like Byron where the winters can get very cold, you often have to depend on your heater to keep your home warm. Energy-efficient windows can reduce how hard your heater needs to work to heat your home.
Estimated Cost of Window Replacement in Byron
Windows come in various purposes, shapes and styles, so costs and services will vary considerably depending on several factors. Below, we go over the typical cost and services that you can get from window installers.
How Much Do New Windows Cost?
Typically, Byron homeowners can expect their replacement window installations to range from $250 to $1,200. The most common installations sit at about $600. This is because of the fact that window installations depend on several 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.
Whether or not you want to install energy-efficient windows is another factor that will influence the cost. These will almost always cost more than other windows, but on the other hand, you can save about $309 a year on your energy bills in Byron.
Another factor that influences the overall cost is the material of the frame you pick. Aluminum frames are usually the least expensive and are sturdy and relatively maintenance-free, but they offer poor insulation. On the other hand, wood frames are the most expensive because they are aesthetically pleasing and offer 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 a window installation is: Do you need a full-frame installation or a pocket installation?
A full-frame installation replaces the total window, such as the sill, frame, trim and the window panes. As this type of installation requires more time, it will cost more than a pocket installation. A pocket installation involves installing a new window within the frame that's already there. This means instead of removing the whole unit and rebuilding it, the installer will just put the replacement window (also called a retrofit or insert window) into the frame.
If you're still debating which type of installation to get, you can talk to your installer and get their recommendation. The decision mostly depends on the age of your window frames and if there's any damage.

How We Choose the Best Window Installers in Byron
In our search to find the most reliable, eco-friendly window installers in Byron, the EcoWatch team assessed many companies before deciding on these. Along with energy efficiency, we analyzed several window installers in Byron and assigned rankings using the following methodology:
Service Area
Because this is a guide for Byron, we gave more points to companies that cover the city. There are other reputable providers that didn't make the list because they wouldn't be able to serve homeowners in Byron.
Work Quality
When choosing new windows, the quality and range of services often plays just as important of a role in overall efficiency and performance as the brand of window you choose. We do give window installers higher marks if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
We analyzed patterns in recent online reviews to find the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it reflects the quality of services across most other categories, including cost, quality of parts, quality of installation, professionalism, warranty and more.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers want to keep costs low when possible. When analyzing providers' prices, we gave higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
Protecting your investment in new windows is important to many homeowners. That's why window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of Byron's climate, homeowners will want to mitigate rot, low efficiency and water damage. 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
What is the average cost to install windows?
The national average cost to install a single window is around $600 but can range from $200 to $1,200, depending on several factors. The price is generally dependent on the location of your property, the size of the window and the type and material of the window. Also, bear in mind that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.
What kind of window is the most energy-efficient?
A window's energy efficiency depends on a variety of factors, including the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are usually the most energy-efficient since they are certified by the U.S. Department of Energy.
Do I really have to use a window installation company?
Unless you're handy and have the time needed to replace your own windows, we recommend hiring a professional. The process of installing windows is quite involved and can take anywhere from four to six hours for one window. Although it's tempting to try to save money by doing it yourself, hiring a professional is a faster, more efficient and safer alternative.
How often should you replace windows?
Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, they probably need to be replaced. Apart from that, if your windows have any damage on them, or they have become difficult to open or close, they may need to be replaced.
