How Installing Energy-Efficient Windows in Mundelein Saves You Money
By upgrading to energy-efficient windows, you can take advantage of several benefits, such as:
- Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.
- Reduce your carbon footprint: By using less energy once switching to energy-efficient windows, you’ll also be reducing your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Save money on electricity bills: According to the Department of Energy, heat gained or lost through windows accounts for around 25-30% of residential energy use. Upgrading to energy-efficient models can help reduce how much you have to pay, therefore saving you about 12% more on your bills.
- Protect your investment: If your home is on the older side, your windows are most likely outdated. Upgrading your windows can make your home more comfortable and also help raise the value of your property if you decide to sell.
Estimated Cost of Window Replacement in Mundelein
When looking into window installation, each company offers varying services and costs. Let’s go over some average costs and services.
How Much Do New Windows Cost?
The average cost to replace a single window is about $600 but can range from $200 to $1,200. How much it will cost varies depending on several factors, including size, material, the location of your home, type, number of windows and more.
It’s important to keep in mind that windows with higher efficiency may cost more upfront but can save you hundreds of dollars by decreasing your energy bills. Investing in certified energy-efficient windows can save Mundelein homeowners $298+ a year when replacing single-pane windows.
Another factor that influences the overall cost is the material of the frame you select. Aluminum frames are typically the least expensive and are sturdy and light, but they offer poor insulation. On the other hand, wood frames are the most expensive because they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.
What Services do Window Installers Offer?
There are typically two kinds of window installation services: full-frame and pocket installations.
A full-frame installation is a replacement of the full window. It involves taking out the old window, the sill, and the exterior and interior trim. It can also involve other 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 (or retrofits) involve replacing a window within its existing frame, which makes pocket installations less labor-intensive and costly. But, if the frame has any damage or rot, you will likely need a full-frame installation instead.
Your window installation company will be able to advise you on the best type for your project. In Mundelein, the decision will mostly be based on the efficiency of your home and how old your existing frames are.

How We Choose the Best Window Installers in Mundelein
In our search to find the most reliable, eco-friendly window installers in Mundelein, EcoWatch chose the above companies as the top window installation companies in the city. Along with energy efficiency, we evaluated window companies all across the state and assigned rankings using the following methodology:
Service Area
This one is pretty self-explanatory, but we’ve chosen to highlight window installation companies that serve Mundelein so you can find a quality window installation company near you.
Work Quality
When choosing new windows, the quality and variety of services can often play just as important of a role in overall efficiency and performance as the brand you opt for. 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
Another self-explanatory yet super important review factor is customer feedback. If the majority of customers don’t have positive feedback about their service from a certain installer, it won’t be featured on EcoWatch.
Cost
This one is a give-and-take: similar to other services, cheap window installers may not 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
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 installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to Mundelein’s climate, homeowners will want to mitigate rot, water damage and low efficiency. We factored in local experience to reflect the ability of Mundelein window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
