How Installing Energy-Efficient Windows in Merrillville Saves You Money
Switching to energy-efficient windows can improve the comfort of your home and help you save on electricity bills. Here are more ways upgrading your windows could help you:
- Protect your investment: If you have a relatively old home, your windows are most likely in need of replacement. Upgrading your windows can improve the insulation in your home and also help raise the value of your house if you decide to sell.
- Reduce your carbon footprint: Since energy-efficient windows improve the insulation in your house, you can cut your carbon footprint by about 12%, according to Energy Star.
- Save on energy bills: According to the Department of Energy, heat gained or lost through windows accounts for around 25-30% of residential energy use. Switching to energy-efficient models can help decrease that number, 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 harmful UV rays, preventing your furniture, carpet and other valuables from fading.
Estimated Cost of Window Replacement in Merrillville
Each window installation company offers various services and has varying prices depending on a few factors.
How Much Do New Windows Cost?
Generally, Merrillville homeowners can expect their window replacements to range from $250 to $1,200. The most common installations sit at around $600. Costs will differ considerably based on the current condition of your home, the quality of your products, your location and the number of windows you need. A lot of window companies also offer replacement door installations and other add-ons like coating, shutters, baths and more. Additional services will increase your overall project costs.
It's also worth noting that energy-efficient windows will almost always cost more initially, but Energy Star predicts that switching out the windows on your Merrillville home can mean an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. The amount of money you'll save by upgrading to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
We recommend getting free quotes from several window installers to find the right windows and the company that works best for you.
What Services do Window Installers Offer?
There are generally two kinds of window installation services: full-frame and pocket installations.
A full-frame installation is a total window replacement. It involves removing the old window, the sill, and the exterior and interior trim. It also involves extra materials, like insulation and drip edges, which increase the overall cost of the project. Also worth noting: you may have to touch up the paint around the window after a full-frame installation. A pocket installation involves installing a new window without replacing the frame. This means instead of tearing out the whole window and reinstalling it, the installer will just put the replacement window (also called a retrofit or insert window) into the frame.
Your window installer can help you decide which type of installation you need.

How We Choose the Best Window Installers in Merrillville
In our hunt to make your home improvements easier and more eco-friendly in Merrillville, EcoWatch examined dozens of companies before landing on these. We have reviewed the best window installation companies in Merrillville mostly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows have been shown to cut your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
This one is self-explanatory, but we've chosen to highlight window installation companies that serve a wide variety of states and cities so you can find the right window installation company near you.
Work Quality
When picking new windows, the quality and breadth of services often plays just as important of a role in overall efficiency and performance as the brand of window you choose. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
Another self-explanatory yet super important review factor is customer feedback. If most customers don't have positive things to say about their service from a certain installer, it won't be featured on EcoWatch.
Cost
This one is a give-and-take: similar to other services, cheap window companies are not going to 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. That's why window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have been in the industry for a while. Window installers that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
