How Installing Energy-Efficient Windows in Round Lake Saves You Money
Energy-efficient windows can benefit you in more than one way. Here are a few reasons you may want to think about making the switch:
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
- Save on power bills: According to the Department of Energy, heat gained or lost through windows accounts for around 25-30% of household energy use. Installing energy-efficient models can help decrease that number, therefore saving you about 12% more on your bills.
- Better temperature control in your home: Energy-efficient windows can cut back on how much heat is lost through your windows when heating your home.
- Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its value, particularly if you have an older home.
Estimated Cost of Window Replacement in Round Lake
Let's take a look at the cost of replacing your windows and the kinds of services offered by installers.
How Much Do New Windows Cost?
The typical cost to replace a single window is about $600 but can range anywhere from $200 to $1,200. These estimates vary depending on specific characteristics of your installation, like type, size, number of windows, the location of your home, material and more.
With windows, efficiency is the most important factor for most homeowners. Windows with higher efficiency may cost more initially, but by increasing the efficiency of your home — especially during the summer and winter — they can give you decades of energy savings. According to Energy Star, buying certified energy-efficient windows can save Round Lake homeowners $298+ each year after replacing single-pane windows.
We recommend requesting free quotes from multiple window installation companies to find the right windows and the company that works best for you.
What Services do Window Installers Offer?
Generally, there are two kinds of window replacement services companies provide: full-frame and pocket installations.
Full-frame installations require replacing the full window — the sill, frame, trim and all. These are most common when you want to change the style of your window or when it has a great amount of deterioration. Full-frame installations require more time and labor and will increase overall costs. Pocket installations (or retrofits) entail replacing a window within the existing frame, which makes pocket installations more simple and affordable. But, if the frame has any damage or rot, you will likely need a full-frame installation instead.
Your window installer can help you decide which type of installation you need.

How We Choose the Best Window Installers in Round Lake
In our hunt to make your home improvements easier and more eco-friendly in Round Lake, the EcoWatch team landed on the above companies as the top window installation companies in the city. We've reviewed the top window installers in Round Lake mainly based on energy efficiency, as it's the most sustainable option and the best one for homeowners. Energy Star certified windows can lower power bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
Since this is a guide for Round Lake, we only included companies that serve the city. There are certainly other reputable providers that didn't make the list because they wouldn't be able to serve homeowners in Round Lake.
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 in our guide to ensure its technicians are well-qualified and that the company has gotten tons of positive customer feedback to vouch for its service.
Customer Reviews
Customer feedback is another super important review factor. If most customers don't have nice things to say about their experience with a certain window installation company, you won't see it featured on EcoWatch.
Cost
This one is a give-and-take: as with most services, cheap window installers may not provide the most quality service. Still, we want to make sure we're highlighting companies that provide a range of price and financing options so they're accessible to most homeowners.
Warranty
Protecting your investment in new windows is important. For that reason, window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have a good track record in the industry. Window installers that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Round Lake, IL Window Replacement FAQs
What is the typical cost to install windows?
The national average cost of installing a window is around $600 but can range between $200 and $1,200, depending on a few different factors. The price is typically influenced by the location of your property, the type and material of the window and the size 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.
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 will be more efficient than windows that do. To be sure you'll get the most energy-efficient windows, look for models with the blue Energy Star certification — they're certified energy-efficient by the U.S. Department of Energy.
When should I use a window installation company?
You should hire a window installation professional whenever you need to upgrade your windows. Installing windows is a involved process that can be difficult and time-consuming, so it's best left to the professionals.
How long does it usually take to install windows?
Since the average installation time is 30 minutes per window, around 16 windows can be installed during an 8-hour work day.
