How Installing Energy-Efficient Windows in College Saves You Money
Energy-efficient windows can offer benefits in more than one way. Here are a few reasons you may want to consider making the switch:
- Decrease your carbon footprint: Decreasing the amount of energy you use also lowers your carbon emissions. You could reduce it by 286 pounds per year on average.
- Save money on electricity bills: The Department of Energy estimates that heat gained or lost via windows accounts for around 25-30% of energy use in your home. Installing energy-efficient windows can help lower that number, which helps you save $325 a year on your bills.
- Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Updating your windows can make your home more comfortable and also help increase the value of your property if you decide to sell.
- Protect your valuables from fading: When you switch to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less due to their ability to filter out harmful UV rays.
Estimated Cost of Window Replacement in College
Each window replacement company offers various services and has varying costs based on several factors.
How Much Do New Windows Cost?
Generally, College homeowners can anticipate their replacement window installations to range from $250 to $1,200. The average cost sits at approximately $600. This is because of the fact that the cost of window installations are based on several factors specific to your home, including the size, material and number of windows you need to replace, as well as where your property is located.
It’s also worth keeping in mind that energy-efficient windows will almost always cost more upfront, but Energy Star predicts that switching out the windows on your College home can mean 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.
Costs will also vary depending on the material you pick for your window frames. Aluminum frames are the least expensive. They’re sturdy, light and easy to maintain, but provide poor insulation. Vinyl frames are a bit more expensive and provide good insulation. Composite frames made from wood fibers encased in plastic also offer 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?
The first thing to ask yourself when planning to replace your windows is: Do you want a full-frame installation or a pocket installation?
A full-frame installation replaces the complete window, including the sill, frame, trim and the window panes. Because this kind of installation requires more time and labor, it will cost more than a pocket installation. Pocket installations are on the simpler end and won’t carry as large a bill because they entail simply replacing the window within its existing frame. But if the frame has any damage or deterioration, you may need a full-frame installation instead.
Your window installation company can help you figure out which type of installation you need.

How We Choose the Best Window Installers in College
In our hunt to find the most reliable, eco-friendly window installers in College, the EcoWatch Reviews team landed on the above companies as the top window installation companies in the city. We’ve assessed the top window installation companies in College primarily based on their energy efficient offerings, as it’s the most sustainable option and the best one for homeowners. Energy Star certified windows have been shown to cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
Because this is a guide for College, we only included companies that serve the city. There are certainly reputable providers that didn’t make our list because they wouldn’t be able to serve homeowners in College.
Work Quality
We’re willing to bet that you’re looking for a company to do a great job installing windows. We’ve vetted each company 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
We analyzed trends in recent online reviews to find 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 quality of installation, warranty, cost, professionalism, quality of parts and more.
Cost
This one is a give-and-take: as with most services, cheap window installers won’t always provide the highest quality service. Still, we want to ensure we’re highlighting companies that provide a range of price and financing options so they’re accessible to most homeowners.
Warranty
As discussed, windows are a sizable investment, so you’ll want to be certain that investment is well protected. Window installation companies that provide 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 quite some time. Window installers that have more years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
