How Installing Energy-Efficient Windows in Sullivan Saves You Money
Energy-efficient windows can benefit you in several ways. Here are some reasons you may want to consider making the switch:
- Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes tend to have windows that are outdated, leaky or potentially even damaged in some way. Upgrading your windows could help raise the value of your property if you decide to sell.
- Decrease your carbon footprint: Since energy-efficient windows improve the insulation in your home, you can lower your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Save on power bills: According to the Department of Energy, heat gained or lost through windows accounts for around 25-30% of residential energy use. Installing energy-efficient models can help lower how much energy is used in your home, therefore saving you about 12% more on your bills.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in Sullivan
Each window replacement company provides various services and has varying price points based on a few factors.
How Much Do New Windows Cost?
Even though the average to replace one window is about $600, it can range from $200 to $1,200. How much it will cost you is based on several factors, such as number of windows, size, the location of your home, material, type and more.
It's important to note that windows with the best efficiency may cost more initially but can save you hundreds of dollars via returns on your energy bills. Investing in Energy Star certified windows can save Sullivan homeowners $311+ a year when replacing single-pane windows.
Costs will also vary based on the material you want for your window frames. Aluminum frames cost the least. They're sturdy, light and maintenance-free, but provide poor insulation. Vinyl frames are a bit more expensive and provide good insulation. Composite frames made with wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They're also aesthetically pleasing and provide decent insulation for your home.
What Services do Window Installers Offer?
In general, there are two kinds of window replacement services companies offer: full-frame and pocket installations.
A full-frame installation replaces the total window, such as the windowsill, frame, trim and the window panes. As this type of installation requires more time, it will cost more than a pocket installation. Pocket installations are on the simpler end and won't cost as much, as they entail merely replacing the window within its existing frame. But if the frame has any damage, you may need a full-frame installation instead.
If you're still trying to decide which type of installation you need, you can talk to your provider and get their advice. The decision mostly depends on the age of your window frames and if there's any damage.

How We Choose the Best Window Installers in Sullivan
In our hunt to find the most reliable, eco-friendly window installers in Sullivan, the EcoWatch team landed on 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 ranked them based on the following methodology:
Service Area
Because this is a guide for Sullivan, we paid more attention to companies that cover the city. There are other reputable providers that didn't make the list because of the low odds that they would serve the average homeowner in Sullivan.
Work Quality
We're willing to bet that you're not looking for a company to do a shoddy job installing windows. We've vetted each company on this list to ensure its contractors are well-qualified and that the company has received lots of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent customer feedback to determine the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across nearly every category, including professionalism, cost, quality of parts, quality of installation, warranty and more.
Cost
This one is a give-and-take: similar to other services, cheap window installation companies won't always provide the highest quality service. Still, we want to ensure we're highlighting companies that offer a variety of price and financing options so they're accessible to most homeowners.
Warranty
As discussed previously, windows are a significant investment, so you'll want to be certain that investment is well protected. Window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of Sullivan's climate, homeowners need to be wary of water damage, rot and low efficiency. We factored in local experience to reflect the ability of Sullivan window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Sullivan, IL Window Replacement FAQs
How much should window installation cost?
The typical cost to replace a window can range from $450 to $650. There are several factors that influence the cost, which include the number of windows, how energy-efficient the windows are, your property's location, styles and sizes of windows, the materials used in designing the windows and local labor costs.
What type of window is the most energy-efficient?
Generally, double-pane windows are more efficient than single-pane windows and windows that don't open will be more efficient than windows that do. To be sure you're getting the most energy-efficient windows, look for models that have the blue Energy Star certification attached to them — this means they're certified energy-efficient by the U.S. Department of Energy.
What services do window installation companies offer?
Window installation professionals go to your property to remove your old windows and replace them with new ones. Some providers install products distributed by other companies, whereas others install their own windows. The installer will also clean up after the installation.
What time of year is the best time to replace my windows?
Though you can install windows any time of year, warmer weather is often better for replacing windows. Additionally, it shouldn't be raining, since rain can make the installation more difficult.
How do you know it's time to replace your windows?
Windows typically have a lifespan of around 20 to 30 years, but anytime you see damage on your windows, it's a good time to have an expert take a look at them to see if they are in need of a repair or replacement.
