How Installing Energy-Efficient Windows in Loves Park Saves You Money
When you upgrade to energy-efficient windows, you may see several perks, such as:
- Decrease your carbon footprint: By using less energy after you switch to energy-efficient windows, you'll also be cutting your carbon dioxide emissions by about 12%, according to Energy Star.
- Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.
- Save money on electricity bills: Because energy-efficient windows lower the amount of energy used to heat or cool your home, the switch can help you save around $318 annually on your energy bills in Loves Park.
- Protect your investment: If your home is on the older side, your windows are most likely outdated. Updating your windows can make your home more comfortable and also help increase the value of your house if you decide to sell.
Estimated Cost of Window Replacement in Loves Park
When researching window installation, each company provides varying services and prices. Let's take a look at some average costs and services.
How Much Do New Windows Cost?
The typical cost to replace one window is about $600 but can range from $200 to $1,200. But prices differ remarkably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also provide door replacements, which carry a higher price tag.
It's also worth noting that energy-efficient windows will almost always cost more upfront, but Energy Star predicts that switching out the windows on your Loves Park home can mean an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. How much you'll save by upgrading to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
The cost of your window installation will also vary depending on the kind of window material you choose for the frames. Wood windows are typically the most expensive, although it depends if they are completely 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?
The first question to ask yourself when planning to replace your windows is: Do you want a full-frame installation or a pocket installation?
A full-frame installation is a replacement of the total window. This service involves taking out the old window, the windowsill, and the exterior and interior trim. It also involves extra materials, including insulation and drip edges, which increase the total cost of the project. It's also worth noting that you may have to touch up the paint surrounding the window after a full-frame installation. Pocket installations are simpler and won't carry as large a bill because they entail merely replacing the window within its existing frame. But if the frame has any damage or deterioration, you may need a full-frame installation instead.
If you're still trying to decide which kind of installation you should get, you can ask your provider and get their advice. The choice mostly depends on how old the frames are and if there's any damage.

How We Choose the Best Window Installers in Loves Park
In our search to find the most reliable, eco-friendly window installers in Loves Park, the EcoWatch team examined many companies before landing on these. Along with energy efficiency, we analyzed window companies all across the state and assigned rankings based on the following methodology:
Service Area
Because this is a guide for Loves Park, we only included companies that serve the city. There are certainly other reputable providers that didn't make the cut because of the low odds that they would serve the average homeowner in Loves Park.
Work Quality
We're certain that you're not looking for a company to do a shoddy job installing windows. We've vetted each installer on this list to make sure its contractors are well-qualified and that the company has received plenty of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent customer feedback to determine the companies with the most customer satisfaction. Customer satisfaction may be the most important factor, as it indicates the quality of services across nearly every category, including warranty, cost, quality of parts, quality of installation, professionalism and more.
Cost
This one is a give-and-take: as with other services, cheap window companies won't always provide the most quality service. Still, we want to ensure we're highlighting companies that offer a range of price and financing options so they're accessible to most homeowners.
Warranty
Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have a good track record in the industry. Window installation companies that have more experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
Loves Park, IL Window Replacement FAQs
How much does window installation cost?
The national average cost of replacing a single window is around $600 but can range from $200 to $1,200, depending on several factors. The price is often dependent on the type and material of the window, the size of the window and the location of your property. Also, keep in mind that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.
What are the most common kinds of replacement windows?
There are various types of windows you can get for your house, including transom windows, bay windows, awning windows, slider windows, double-hung and single-hung windows, casement windows and picture windows.
When should I use a window installation company?
Unless you have experience with home improvement projects and have the time needed to replace your own windows, we recommend hiring a professional installer. The process of installing windows is complex 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.
What time of year is a good time to replace my windows?
Although you can install windows any time of year, warmer weather is typically better for installing replacement windows. In addition, the weather should be dry, because rain can make the installation more difficult.
Should I replace my windows all at once?
If you're upgrading your windows to save on your energy bills, replacing all of the windows at once is the only way to see a noticeable difference. On the other hand, if you have only one or two windows that are broken or drafty, you can replace just those.
