Why you can trust EcoWatch
Although eco-friendly energy sources like wind and solar are important when it comes to lowering your carbon footprint, improving your house's energy efficiency can also have a considerable impact on home energy conservation. The Department of Energy estimates that heat or cool air lost through old or damaged windows could be responsible for around 30% of heating and cooling usage. In Sparta, where the power bills are an average of $32 per month, that's almost $$114 per year wasted.
That's also bad for the environment because the additional energy required by outdated windows increases your carbon footprint.
So if you're building a new home, renovating or changing out old windows in Sparta, you've found the best place to get started.

How Installing Energy-Efficient Windows in Sparta Saves You Money
When you switch to energy-efficient windows, you may see some benefits, such as:
- Reduce your carbon footprint: By using less energy after you switch to energy-efficient windows, you'll also be reducing your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its value, especially if you have an older home.
- Save money on power bills: The Department of Energy estimates that heat gained or lost through windows makes up around 25-30% of energy use in your home. Switching to energy-efficient windows can help reduce that amount, which helps you save some money on your bills.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only insulate your home better, but also filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in Sparta
Let's go over the cost of replacing your windows and the types of services you may need for your home.
How Much Do New Windows Cost?
The average cost to install a single window is about $600 but can range from $200 to $1,200. Costs will vary considerably depending on the number of windows you need, the quality of your products, your location and the current condition of your home. A lot of window companies also offer door installations and other add-ons like coating, baths, shutters and more. Additional services will increase your overall project costs.
With windows, efficiency is the most important factor for many homeowners. Efficient windows may cost more upfront, but by increasing the efficiency of your home — especially during the summer and winter — they can provide decades of energy savings. According to Energy Star, buying certified energy-efficient windows can save Sparta homeowners $315+ a year after replacing single-pane windows.
We recommend getting free quotes from multiple window installers to find the one that works best for you.
What Services do Window Installers Offer?
When considering window replacements, in general there are two kinds that your installer will have: full-frame and pocket installations.
A full-frame installation replaces the complete window, such as the windowsill, frame, trim and the window panes. As this type of installation requires more time and labor, it will be more expensive than a pocket installation. Pocket installations (also known as retrofits) are when you replace a window without replacing the frame. Pocket installations are simpler and won't cost as much, but you can't do this type of installment if you have any pre-existing rot or water damage.
Your window replacement company should be able to help you understand what's best for your needs. In Sparta, the decision will mostly depend on how old your windows are and if there's any moisture damage. Wood can decay if it's not maintained properly over the years, so it's good to have a professional check your frames and window sills.

How We Choose the Best Window Installers in Sparta
In our hunt to make your home improvements easier and more eco-friendly in Sparta, EcoWatch landed on the above companies as the top window installation companies in the city. Along with energy efficiency, we evaluated each installer and ranked them based on the following methodology:
Service Area
Because this is a guide for Sparta, we only included companies that serve the city. There are other reputable providers that didn't make the cut because they wouldn't be able to serve homeowners in Sparta.
Work Quality
When picking new windows, the quality and variety of services often plays just as important of a role in overall efficiency and performance as the brand you choose. We do give window installers higher marks if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
We analyzed patterns in recent online reviews to determine the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it reflects the quality of services across nearly every category, including warranty, cost, quality of installation, quality of parts, professionalism and more.
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 provide 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 with 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 proven track record in the industry. Window installation companies that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.
Sparta, IL Window Replacement FAQs
How much does window installation cost?
The national average cost to replace one window is about $600 but can range from $200 to $1,200, based on a variety of factors. The price is typically influenced by the type and material of the window, the size of the window and the location of your property. Also, remember that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.
Which kind of window is the best?
A window's energy efficiency is influenced by a variety of factors, including the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are typically the most energy-efficient since they are certified by the U.S. Department of Energy.
Do I really have to use a window installation company?
You should use a window installation company whenever you need to upgrade your windows. Installing windows is a complex process that can take a lot of time, so it's best left to the professionals.
What time of year is a good time to replace my windows?
Though you can install windows any time of year, warmer weather is typically better for replacing windows. In addition, the weather should be dry, because rain can make the installation more difficult.
Should I replace all my windows at the same time?
If your windows are more than 20 years old, it's probably time to replace all of them. At that point, they are often less efficient, draftier and/or more damaged than new windows. Replacing your windows all at once will involve less paperwork and less time.
