How Installing Energy-Efficient Windows in Gary Saves You Money
When you upgrade to energy-efficient windows, you may see some benefits, such as:
- Protect your valuables from fading: When you switch to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will fade less because of their ability to filter out damaging UV rays.
- Reduce your carbon footprint: By using less energy once you switch to energy-efficient windows, you’ll also be decreasing your carbon dioxide emissions by about 12%, according to Energy Star.
- 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 Older homes tend to have windows that are outdated, drafty or potentially even damaged in some way. Upgrading your windows could help raise the value of your home if you decide to sell.
- Save on energy bills: After you install energy-efficient windows, you can expect a reduction in your bills by about 12% since you’ll use less energy to heat or cool your home.
Estimated Cost of Window Replacement in Gary
Each window installer provides various services and has varying costs depending on several factors.
How Much Do New Windows Cost?
On average, Gary homeowners can expect their window installations to range from $250 to $1,200. The most common installations sit at approximately $600. How much it will cost is based on several factors, such as size, the location of your home, type, material, number of windows and more.
With windows, efficiency is one of the most important factors for many homeowners. Windows with higher efficiency may cost more initially, but by increasing the efficiency of your home — particularly during the summer and winter — they can give you decades of energy savings. According to Energy Star, buying certified energy-efficient windows can save Gary homeowners $391+ each year after replacing single-pane windows.
We advise requesting free quotes from several window companies to find the right windows and the company that works best for you.
What Services do Window Installers Offer?
The first thing to ask yourself when planning on installing new windows is: Do you need a full-frame installation or a pocket installation?
Full-frame installations entail replacing the full window, including the trim, sill and frame. Full-frame installations are necessary when you want a new style or your window has significant damage or rot. Because these installations are more involved, they will increase the overall cost. A pocket installation entails replacing a window without replacing the frame. So, instead of tearing out the whole unit and reinstalling it, the contractor will just slide the replacement window (also called a retrofit or insert window) into the frame.
Your window installation company will be able to help you decide what’s best for your needs. In Gary, the decision will mostly depend on how old your home is and if there’s any moisture damage. Wood can decay if not properly maintained over the years, so it’s a good idea to have a professional evaluate your frames and window sills.

How We Choose the Best Window Installers in Gary
EcoWatch reviews are different from most reviews, as we look at these companies through a sustainability lens. We’ve evaluated the best window replacement companies in Gary mainly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows can reduce your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
Because this is a guide for Gary, we paid more attention to companies that cover the city. There are certainly reputable providers that didn’t make the cut because they wouldn’t be able to serve homeowners in Gary.
Work Quality
We’re certain that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each company 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
We analyzed patterns in recent online reviews to find the companies with the most customer satisfaction. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across nearly every category, including warranty, cost, professionalism, quality of installation, quality of parts and more.
Cost
Cheaper windows certainly don’t mean better windows, but we know many of our readers would like to keep costs low when possible. When analyzing the prices of providers, we awarded higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
As discussed previously, windows are a significant investment, so you’ll want to be certain that investment is well protected. Window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of Gary’s climate, homeowners need to be wary of low efficiency, water damage and rot. We factored in local experience to reflect the ability of Gary window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
