How Installing Energy-Efficient Windows in Bonus Saves You Money
There are quite a few perks of upgrading to energy-efficient windows. Some reasons you may want to consider making the change are the following:
- Save money on power bills: Installing energy-efficient windows lowers your energy bills by about 12% because you need less energy.
- Better temperature control in your home: Energy-efficient windows can lower the amount of heat lost through your windows when heating your home.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only insulate your home better, but also filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
- Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Upgrading your windows can make your home more comfortable and also help increase the value of your property if you decide to sell.
Estimated Cost of Window Replacement in Bonus
Windows come in varying purposes, shapes and styles, so costs and services will differ remarkably depending on your project. Below, we detail the average cost and services that you can get from window installers.
How Much Do New Windows Cost?
Even though the typical to replace a single window is around $600, it can range anywhere from $200 to $1,200. This is due to the fact that the cost of window installations are based on a variety of factors specific to your home, such as the size, material and number of windows you need to replace, as well as where your property is located.
With windows, efficiency is one of the most important factors for many homeowners. High efficiency windows may cost more initially, but by increasing the efficiency of your home — especially during the summer and winter — they can give you many years of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Bonus homeowners $318+ a year after replacing single-pane windows.
Another factor that affects the overall cost is the material you select for your frame. Aluminum frames are generally the least expensive and are sturdy and relatively maintenance-free, but they offer poor insulation. On the other hand, wood frames cost the most 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 step when planning a replacement is to clarify whether you need a full-frame or pocket installation.
Full-frame installations are necessary when you want to change the style of your windows or your window has significant rot or deterioration. With this service, your installers will replace the complete window, including the frame, sill and trim. A pocket installation involves replacing a window within the existing frame, which tends to be less expensive than a full-frame installation.
If you're not sure which kind of window installation service you should get, your installer can assist you. In general, the choice is influenced by factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Bonus
The EcoWatch Reviews team is different from most reviewers, as we evaluate these companies through a sustainability lens. Along with energy efficiency, we evaluated window companies all across the state and ranked them based on the following methodology:
Service Area
Since this is a guide for Bonus, we gave more points to companies that serve the city. There are certainly other reputable providers that didn't make our list because of the low odds that they would serve the average homeowner in Bonus.
Work Quality
We're willing to bet that you're looking for a company to do a great job installing windows. We've vetted each company in our guide to make sure its technicians are well-qualified and that the company has gotten plenty of positive customer feedback to vouch for its service.
Customer Reviews
Customer feedback is another very important review factor. If most customers don't have good feedback about their service from a certain installer, you won't see it featured on EcoWatch.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing the prices of providers, we gave higher scores 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 provide 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 earn higher rankings by our standards. We like to see at least ten years of experience.
Bonus, IL Window Replacement FAQs
What is the typical cost to install new windows?
The national average cost to install a window is about $600 but can range between $200 and $1,200, based on several factors. The price is often influenced by the location of your property, the size of the window and the type and material of the window. Also, keep in mind that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.
What are the different types of windows?
There are various kinds of windows you can get for your home, including picture windows, bay windows, awning windows, casement windows, double-hung and single-hung windows, transom windows and slider windows.
When do I need to 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 quite involved and can take anywhere from four to six hours for a single window. Although it's tempting to try to save some money by doing it yourself, hiring a professional is a faster, more efficient and safer option.
Should I replace all my windows at the same time?
If your windows are more than 20 years old, you most likely need to replace all of them. By that point, they are typically less efficient, draftier and/or more damaged than new windows. Replacing your windows all at once will involve less paperwork and less time.
