How Installing Energy-Efficient Windows in Greene Saves You Money
Energy-efficient windows can offer benefits in several ways. Here are a few reasons you may want to make the switch:
- Reduce your carbon footprint: In Greene, you can cut your indirect greenhouse gas emissions by about 286 pounds per year when you upgrade to energy-efficient windows.
- Save money on energy bills: Upgrading to energy-efficient windows reduces your energy bills by about 12% because you use less energy.
- Protect your investment: When your home is on the older side, your windows could also be outdated or leaky. Keeping your windows up to date is an important part of maintaining your property and its real estate value.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in Greene
When researching window installation, each company offers varying services and prices. Let’s take a look at some average costs and services.
How Much Do New Windows Cost?
According to our market research, the average cost of replacing a single window is about $600. However, window installation costs can range from $200 to $1,200 a window. This is because 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.
Whether or not you want energy-efficient windows is another factor that will determine the cost. These will typically cost more than other windows, but on the other hand, you can save about $304 a year on your energy bills in Greene.
Costs will also vary based on the material of your frame. Aluminum frames cost the least. They’re sturdy, light and maintenance-free, but offer poor insulation. Vinyl frames are a bit more expensive and offer 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 offer decent insulation for your home.
What Services do Window Installers Offer?
There are typically two kinds of window replacement services: full-frame and pocket installations.
Full-frame installations involve replacing the full window — the sill, frame, trim and all. These are typically done when you want a new style for your windows or when it has significant rot or deterioration. Full-frame installations are more time-consuming and will increase overall costs. A pocket installation involves replacing a window without replacing the frame. This means instead of tearing out the whole unit and rebuilding it, the contractor will just put 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 Greene, the decision will mostly be based on the age of your home and if there’s any moisture damage. Wood can decay if it’s not properly maintained over the years, so it’s good to have a professional assess your frames and window sills.

How We Choose the Best Window Installers in Greene
In our search to find the most reliable, eco-friendly window installers in Greene, EcoWatch chose the above companies as the top window installation companies in the city. Along with energy efficiency, we assessed each installer and ranked them using the following methodology:
Service Area
Since this is a guide for Greene, we only included companies that serve the city. There are certainly reputable providers that didn’t make the list because of the low odds that they would serve the average homeowner in Greene.
Work Quality
When picking new windows, the quality and variety of services can often play just as important of a role in insulation and performance as the type of window you choose. We do give window installers more points if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
We analyzed patterns in recent customer feedback to find the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction may be the factor we place the most value on, as it indicates the quality of services across most other categories, including warranty, quality of parts, professionalism, quality of installation, cost 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 make sure 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 serious investment, so you’ll want to make sure that investment is protected. Window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of Greene’s climate, homeowners need to be wary of rot, water damage and low efficiency. We factored in local experience to reflect the ability of Greene window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.

When is the best time of year to replace windows?
Replacement windows can be installed during any season, but autumn might be best.
