How Installing Energy-Efficient Windows in Glens Falls Saves You Money
When you upgrade to energy-efficient windows, you may see some benefits, including:
- Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.
- Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes usually have windows that are outdated, leaky or maybe even damaged in some way. Updating your windows could help increase the value of your property if you decide to sell.
- Save on energy bills: Because energy-efficient windows decrease how much energy you need to heat or cool your home, the switch can help you save around $433 annually on your energy bills in Glens Falls.
- Better temperature control in your home: When you live in a place like Glens Falls where the summers can be pretty warm, you often need to depend on your air conditioner to keep your home cool. Energy-efficient windows can reduce how hard your AC needs to work to cool your home.
Estimated Cost of Window Replacement in Glens Falls
Let's go over the cost of updating your windows and the types of services offered by installers.
How Much Do New Windows Cost?
Though the average of replacing a single window is around $600, it can range from $200 to $1,200. But costs differ remarkably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also provide door installations, which will add extra costs to your project.
With windows, efficiency is the most important factor for most homeowners. Efficient windows may cost more upfront, but by increasing the efficiency of your home — particularly during the winter — they can provide many years of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Glens Falls homeowners $433+ a year after replacing single-pane windows.
The cost of your window installation will also vary based on the type of material you choose for the frames. Wood windows are typically the most expensive, though it depends if they are solid wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are shown to be more efficient.
What Services do Window Installers Offer?
There are generally two kinds of window replacement services: full-frame and pocket installations.
Full-frame installations are usually done when you want a new style or your window has a lot of deterioration. With this service, your professionals will replace the whole window, including the trim, frame and sill. Pocket installations are simpler and won't carry as large a bill, as they entail merely replacing the window within its existing frame. But if the frame has any damage or rot, you should opt for a full-frame installation instead.
Your window installation company can help you figure out which type of installation you should get.

How We Choose the Best Window Installers in Glens Falls
EcoWatch reviews differ from most reviews, as we assess these companies through a sustainability lens. Along with energy efficiency, we reviewed window companies all across the state and ranked them using the following methodology:
Service Area
Because this is a guide for Glens Falls, we only included companies that cover the city. There are certainly other reputable providers that didn't make the cut because of the low odds that they would serve the average homeowner in Glens Falls.
Work Quality
We're certain that you're looking for professionals who do a great job installing windows. We've vetted each company in our guide to ensure its technicians are well-qualified and that the company has gotten 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 highest rates of customer satisfaction. Customer satisfaction may be the most important factor, as it indicates the quality of services across nearly every category, including cost, professionalism, quality of parts, warranty, quality of installation and more.
Cost
This one is a give-and-take: similar to most services, cheap window companies 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 previously, windows are a considerable investment, so you'll want to make sure that investment is protected. Window installation companies that give you 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 installers that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
