Why you can trust EcoWatch
Although renewable energy sources like wind and solar are important when it comes to decreasing your carbon footprint, improving your house's energy efficiency can also have a large impact on home energy conservation. According to the Department of Energy, heat or cool air lost through outdated, drafty windows could represent 25-30% of heating and cooling use.
Installing energy-efficient windows on your house can help you save money every month on your energy bills — and you can help the environment, too.
Efficient windows are particularly important in Looking Glass, where the temperature varies throughout the year. According to Energy Star, making the switch to energy-efficient windows can save the average homeowner up to $313 each year.

How Installing Energy-Efficient Windows in Looking Glass Saves You Money
There are several benefits of upgrading to energy-efficient windows. A few reasons you may want to consider making the change are the following:
- Save money on energy bills: The Department of Energy estimates that heat gained or lost through windows makes up around 25-30% of energy use in your home. Upgrading to energy-efficient windows can help decrease that number, which helps you save some money on your bills.
- Protect your valuables: The low-emissivity coatings on many energy-efficient windows help reduce damage from the sun's UV rays to your floors, carpets and furniture.
- Decrease your carbon footprint: Decreasing the amount of energy you use also lowers your carbon emissions. You could reduce it by 642 pounds per year on average.
- Protect your investment: When you have an older home, your windows could also be outdated or drafty. Keeping your windows up to date is an important part of maintaining your property and its value.
Estimated Cost of Window Replacement in Looking Glass
Windows come in various purposes, styles and shapes, so costs and services will differ tremendously depending on several factors. Below, we go over the typical cost and services that you can get from window installers.
How Much Do New Windows Cost?
Typically, homeowners in Looking Glass can expect that most replacement window installations will cost between $250 and $1,200, with the most common installations sitting at around $600. This is due to the fact that window installations are based on several factors specific to your home, like the size, material and number of windows you need to replace, as well as the location of your property.
It's also worth noting that energy-efficient windows will almost always cost more initially, but Energy Star estimates that switching out the windows on your Looking Glass home translates to an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. How much you'll save by switching to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
The cost of your window installation will also vary based on the kind of material you choose for the frames. Wood windows are generally the most expensive, although it depends if they are solid 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 installation services companies provide: full-frame and pocket installations.
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 professionals will replace the whole window, including the trim, frame and sill. A pocket installation involves replacing a window without removing the whole frame, which is generally less expensive than a full-frame installation.
Your window installation company should be able to help you decide what's best for your needs. In Looking Glass, the decision will mostly depend on how old your home is and if there's any damage. Wood can decay if not properly maintained over the years, so it's a good idea to have a professional check your frames and window sills.

How We Choose the Best Window Installers in Looking Glass
EcoWatch reviews differ from other reviews because we're examining these companies through a sustainability lens. We have decided to evaluate the best window replacement companies in Looking Glass mainly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows have been shown to reduce your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
This one is self-explanatory, but we've chosen to highlight window installers that serve a wide variety of states and cities so you can find a quality window installation company near you.
Work Quality
We're certain that you're looking for a company to do a great job installing windows. We've vetted each installer featured in our guide to make sure its technicians are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.
Customer Reviews
Another self-explanatory yet very important review factor is customer feedback. If most customers don't have good things to say about their experience with a certain company, you won't see it featured on EcoWatch.
Cost
This one is a give-and-take: similar to other services, cheap window installers are not going to provide the highest quality service. On the other hand, 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. For that reason, window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to Looking Glass' climate, homeowners will want to mitigate water damage, rot and low efficiency. We factored in local experience to reflect the ability of Looking Glass window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Looking Glass, IL Window Replacement FAQs
How much does window installation cost?
The national average cost to replace a window is around $600 but can range from $200 to $1,200, based on a variety of factors. The price is typically influenced by the size of the window, the location of your property and the type and material of the window. Also, remember 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 most common types of replacement windows?
There are several different types of windows you can get for your home, such as awning windows, transom windows, bay windows, casement windows, double-hung and single-hung windows, picture windows and slider windows.
When should I use a window installation company?
You should hire a window installation company whenever you want to upgrade your windows. Installing windows is a involved process that can be difficult to do on your own, so it's best left to the professionals.
What time of year should I replace my windows?
Replacement windows can be installed at any time, but warmer weather is typically better. Regardless of when you install them, the contractors will take steps to make sure that too much hot or cold air doesn't get into your home, so the temperature outside doesn't necessarily matter that much. What's more important than the temperature is that the weather should be dry.
Should I replace all my windows at once?
If you're upgrading your windows to save on your energy bills, replacing all your windows together is the only way to gain that benefit. However, if you have just a few windows that are damaged or drafty, you can replace just those.
