How Installing Energy-Efficient Windows in Eldorado Saves You Money
By upgrading to energy-efficient windows, you can benefit in several ways, including:
- Save money on energy bills: After you upgrade to energy-efficient windows, you can expect a reduction in your bills by about 12% because you'll use less energy to heat or cool your home.
- Decrease your carbon footprint: Because energy-efficient windows improve the insulation in your house, you can lower your indirect greenhouse gas 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.
- Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes tend to have windows that are outdated, drafty or potentially even damaged in some way. Upgrading your windows could help increase the value of your property if you decide to sell.
Estimated Cost of Window Replacement in Eldorado
When considering window installation, each company offers varying services and prices. Let's take a look at some average costs and services.
How Much Do New Windows Cost?
Typically, Eldorado homeowners can expect their replacement window installations to range from $250 to $1,200. The average cost sits at around $600. These estimates are based on the specifics of your installation, including the location of your home, size, material, type, number of windows and more.
Bear in mind that energy-efficient windows may cost more upfront, but Energy Star estimates the upgrade will save you between $101 and $583 a year when replacing single-pane windows and between $27 and $197 a year when replacing double-pane, clear glass windows. These savings vary depending on your local climate, energy rates and individual home characteristics.
The cost of your window installation will also vary depending on the type of window material you choose for the frames. Wood windows are generally the most expensive, although it depends if they are 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are shown to be more efficient.
What Services do Window Installers Offer?
In general, there are two types of window replacement services companies offer: full-frame and pocket installations.
Full-frame installations entail replacing the full window, including the trim, frame and sill. Full-frame installations are necessary when you want a new style or your window has significant deterioration. Full-frame installations are more involved and will raise overall costs. Pocket installations (also known as retrofits) are when you replace a window while leaving the existing frame. Pocket installations are simpler and will be less expensive, but you can't do this kind of installment if you have any pre-existing rot or water damage.
Your window installer should be able to help you figure out which type of installation you need.

How We Choose the Best Window Installers in Eldorado
The EcoWatch Reviews team is different from other reviewers since we evaluate these companies through a sustainability lens. Along with energy efficiency, we reviewed several window installers in Eldorado and ranked them using the following methodology:
Service Area
Since this is a guide for Eldorado, we gave more points to companies that cover the city. There are certainly reputable providers that didn't make our list because of the low odds that they would serve the average homeowner in Eldorado.
Work Quality
We're willing to bet that you're looking for professionals who do a great job installing windows. We've vetted each company featured in our guide to make sure its contractors are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed patterns in recent customer feedback to find the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction may be the factor we place the most value on, as it indicates the quality of services across nearly every category, including professionalism, warranty, quality of parts, quality of installation, cost and more.
Cost
This one is a give-and-take: similar to other services, cheap window companies are not going to provide the highest quality service. On the other hand, we want to ensure we're highlighting companies that offer a wide 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 labor rank higher with EcoWatch.
Years of Experience
Due to Eldorado's climate, homeowners will want to mitigate rot, water damage and low efficiency. We factored in local experience to reflect the ability of Eldorado window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Eldorado, IL Window Replacement FAQs
What is the average cost to install new windows?
The typical cost of replacing a window can range between $450 and $650. There are many factors that affect the cost, which include your property's location, local labor costs, styles and sizes of windows, the number of windows, the materials used in designing the windows and how energy-efficient the windows are.
Which type of window should I get?
Generally, double-pane windows will be more efficient than single-pane windows and windows that do not open are more efficient than windows that do. If you want to be sure you'll have the most energy-efficient windows, look for models that have the blue Energy Star certification — this means they're certified energy-efficient by the U.S. Department of Energy.
Can I install my own windows?
If you're handy and have the time and patience to do the job right, you may be able to install your own windows. But if you don't have the time or know-how, we recommend getting a professional to do it for you.
How long does it typically take to install windows?
Each window takes about 30 minutes to install based on the kind of window. However, the window installation can be a two-day job — or more — if you have a lot of windows that need to be installed.
