Why you can trust EcoWatch
Whether you're updating for aesthetics or have old windows, windows play a key role in conserving your home's electricity. Outdated windows can cost you in electricity bills. As a matter of fact, the Department of Energy estimates that about 30% of your house's heat or cool air could be lost through your windows.
That's also bad news for the environment, as the extra energy used by outdated windows increases your carbon footprint.
We've put together this list of the best installation companies to help you in your search, so you can not only enjoy brand new windows, but also save money on your electricity bills.

How Installing Energy-Efficient Windows in Greencastle Saves You Money
Switching to energy-efficient windows can help improve the comfort of your home and help you save on electricity bills. Here are more details about how upgrading your windows could benefit you:
- Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
- Save money on energy bills: Because energy-efficient windows decrease how much energy you need to heat or cool your home, they can help you save around $304 annually on your energy bills in Greencastle.
- 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 property if you decide to sell.
- Reduce your carbon footprint: Because energy-efficient windows improve the insulation in your house, you can lower your indirect greenhouse gas emissions by about 12%, according to Energy Star.
Estimated Cost of Window Replacement in Greencastle
When researching window installation, each company provides varying services and costs. Let's take a look at some average costs and services.
How Much Do New Windows Cost?
According to our research, the average cost to replace a single window is around $600. However, window replacement costs can range from $200 to $1,200 per window. This is due to the fact that window installations are based on several factors specific to your home, such as the size, material and number of windows you need to install, as well as where your property is located.
It's also worth keeping in mind that energy-efficient windows will almost always cost more initially, but Energy Star estimates that upgrading the windows on your Greencastle home can mean an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 per 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.
We advise requesting free quotes from several window installation companies to find the one that works best for you.
What Services do Window Installers Offer?
The first step when planning a window installation is to think about whether you should get a full-frame or pocket installation.
A full-frame installation is a replacement of the full window. This service involves taking out the old window, the windowsill, and the exterior and interior trim. It can also involve extra materials, including insulation and drip edges, which increase the overall cost of the project. It's also worth noting that 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 taking out the whole window and rebuilding it, the window installer will just put the replacement window (also called a retrofit or insert window) into the frame.
If you're still debating which kind of installation you should get, you can ask your installer and get their advice. The choice mostly is influenced by how old the frames are and if there's any damage.

How We Choose the Best Window Installers in Greencastle
In our hunt to make your home improvements easier and more eco-friendly in Greencastle, the EcoWatch Reviews team examined many companies before landing on these. Along with energy efficiency, we analyzed several window installers in Greencastle and ranked them based on the following methodology:
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
We're willing to bet that you're looking for professionals who do a great job installing windows. We've vetted each company in our guide to make sure its contractors are well-qualified and that the company has gotten tons of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed patterns in recent online reviews to determine the companies with the highest rates of customer satisfaction. Customer satisfaction may be the most important factor, as it reflects the quality of services across nearly every category, including warranty, quality of parts, quality of installation, cost, professionalism and more.
Cost
This one is a give-and-take: as with other services, cheap window installation companies are not going to provide the highest quality service. On the other hand, 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 sizable investment, so you'll want to make sure that investment is protected. Window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of Greencastle's climate, homeowners need to be wary of water damage, low efficiency and rot. We factored in local experience to reflect the ability of Greencastle window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Greencastle, PA Window Replacement FAQs
What is the typical cost to install windows in a home?
The national average cost of replacing a window is around $600 but can range between $200 and $1,200, based on a few different factors. The price is often influenced by the size of the window, the type and material of the window and the location of your property. Also, remember that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.
Which kind of window is the best?
Generally, double-pane windows will be more efficient than single-pane windows and windows that do not open are more efficient than windows that do. If you want 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 services do window installation companies provide?
Window installation professionals cover the entire process — from replacing old windows with brand new ones to cleaning up afterward. In addition, a lot of companies offer window manufacturing, customization and repairs.
How long does window installation generally take?
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 need to have a lot of windows installed.
When is it time to replace your windows?
Windows have an average 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.
