How Installing Energy-Efficient Windows in Greenfield Saves You Money
Energy-efficient windows can benefit you in more than one way. Here are some reasons you may want to make the switch:
- Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% once you install Energy Star certified windows. In Greenfield, that's about 286 pounds per year on average.
- Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes usually have windows that are outdated, drafty or maybe even damaged in some way. Upgrading your windows could help increase the value of your property if you decide to sell.
- Save on power bills: Installing energy-efficient windows lowers your energy bills by about 12% because you need less energy.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only insulate your home better, but also filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in Greenfield
Windows come in various shapes, purposes and styles, so costs and services will differ greatly based on several factors. Below, we detail the average cost and services that you can get from window installation companies.
How Much Do New Windows Cost?
The typical cost to install one window is about $600 but can range anywhere from $200 to $1,200. These figures vary depending on specific characteristics of your installation, such as number of windows, the location of your home, material, size, type and more.
It's important to note that windows with higher efficiency may cost more upfront but can save you hundreds of dollars by decreasing your energy bills. Investing in Energy Star certified windows can save Greenfield homeowners $339+ a year when replacing single-pane windows.
Asking for free quotes from multiple providers is the best way to find out which one is right for you.
What Services do Window Installers Offer?
The first thing to ask yourself when planning a window installation is: Do you want a full-frame installation or a pocket installation?
Full-frame installations are necessary when you want to change the style of your windows or your window has a lot of rot or deterioration. With this service, your installers will replace the whole window, including the frame, sill and trim. A pocket installation involves installing a new window within the old frame. This means instead of taking out the whole unit and rebuilding 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 choose what's best for your needs. In Greenfield, the decision will mostly depend on the age of your home and if there's any 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 Greenfield
EcoWatch differs from most reviewers because we assess these companies through a sustainability lens. Along with energy efficiency, we evaluated several window installers in Greenfield and assigned rankings based on the following methodology:
Service Area
Since this is a guide for Greenfield, we gave more points to companies that provide services to the city. There are certainly reputable providers that didn't make the cut because they wouldn't be able to serve homeowners in Greenfield.
Work Quality
When it comes to new windows, the quality and range of services can often play just as important of a role in insulation 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 the majority of customers don't have good things to say about their experience with a certain company, you won't see it featured on EcoWatch.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing providers' prices, we gave higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to Greenfield's climate, homeowners will want to mitigate rot, low efficiency and water damage. We factored in local experience to reflect the ability of Greenfield window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Greenfield, PA Window Replacement FAQs
How much should a window install cost?
The national average cost to replace one window is about $600 but can range from $200 to $1,200, depending on a few different factors. The price is usually dependent on the location of your property, the type and material of the window and the size of the window. Also, keep in mind that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.
Which type of window should I get?
Generally, double-pane windows are more efficient than single-pane windows and windows that do not open are more efficient than windows that do. To be sure you'll get the most energy-efficient windows, look for models that have the blue Energy Star certification attached to them — they're certified energy-efficient by the U.S. Department of Energy.
What do window installers do?
Window installers visit your house to remove your old windows and replace them with new ones. Some companies install products made by other companies, whereas others install their own windows. The installer will also clean up after the installation is done.
How long does it usually take to install windows?
Each window takes about 30 minutes to install based on the kind of window. However, the window installation can be a two-day job — or more — if you have a lot of windows that have to be installed.
How often do you need to replace windows?
Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, then they probably need to be replaced. Other than that, if your windows have any damage on them, or they have become difficult to operate, they may be in need of replacement.
