How Installing Energy-Efficient Windows in Greensburg Saves You Money
Upgrading to energy-efficient windows can improve the comfort of your home and help you save on power bills. Here are more details about how switching out your windows could benefit you:
- Save money on electricity bills: Upgrading to energy-efficient windows lowers your energy bills by about 12% because you need less energy.
- Better temperature control in your home: Residing in a hot city like Greensburg often means depending on your AC to keep your house cool. Energy-efficient windows can lower how much cool air is lost through your windows when cooling your home.
- Decrease 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.
- Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its real estate value, particularly if your home is on the older side.
Estimated Cost of Window Replacement in Greensburg
Windows come in different shapes and sizes, so costs and services will differ greatly. Here are the typical costs and services that you'll find from window installation companies.
How Much Do New Windows Cost?
On average, Greensburg homeowners can expect their replacement window installations to range from $250 to $1,200. The most common installations sit at around $600. How much it will cost you depends on several factors, including material, type, the location of your home, number of windows, size and more.
It's also worth keeping in mind that energy-efficient windows will cost more initially, but Energy Star predicts that switching out the windows on your Greensburg home translates to 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.
We advise requesting free quotes from multiple window installers to find the right windows and the company that works best for you.
What Services do Window Installers Offer?
In regard to window installations, there are generally two types that your installer will have: full-frame and pocket installations.
Full-frame installations entail replacing the total window, including the sill, trim and frame. Full-frame installations are necessary when you want to change the style of your windows or your window has considerable deterioration. Full-frame installations are more involved and will raise the overall cost. Pocket installations (or retrofits) entail replacing a window within the existing frame, which makes pocket installations more simple and affordable. But, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.
If you're unsure which kind of window installation service you should get, your installer can assist you. Typically, the decision is based on factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Greensburg
EcoWatch is different from other reviewers because we evaluate these companies through a sustainability lens. We've reviewed the top window replacement companies in Greensburg mostly based on their energy efficient offerings, as it's what's best for the environment and for you as a homeowner. Energy Star certified windows have been shown to lower energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
Since this is a guide for Greensburg, we only included companies that provide services to the city. There are other reputable providers that didn't make the cut because they wouldn't be able to serve homeowners in Greensburg.
Work Quality
When installing new windows, the quality and variety of services often plays just as important of a role in overall efficiency and performance as the brand you opt for. We do give window installers more points if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
Customer feedback is another super important review factor. If the majority of customers don't have positive feedback about their service from a certain window installation company, you won't see it featured on EcoWatch.
Cost
This one is a give-and-take: as with other services, cheap window companies may not provide the most quality service. Still, we want to make sure we're highlighting companies that provide a wide range of price and financing options so they're accessible to most homeowners.
Warranty
Protecting your investment in new windows is important to many homeowners. That's why window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to Greensburg's climate, homeowners need to be wary of rot, water damage and low efficiency. We factored in local experience to reflect the ability of Greensburg window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Greensburg, PA Window Replacement FAQs
What is the average cost to replace windows in a home?
The national average cost to install one window is about $600 but can range between $200 and $1,200, depending on a variety of factors. The price is often dependent on the location of your property, the type and material of the window and the size of the window. Also, remember that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.
What are the different types of windows?
There are several different kinds of windows you can get for your home, including double-hung and single-hung windows, casement windows, transom windows, bay windows, awning windows, picture windows and slider windows.
What do window installation companies do?
Window installers visit your house to remove your old windows and replace them with new ones. Some companies install products distributed by other companies, whereas others install their own windows. The installer will also clean up after the installation is complete.
How long does it usually take to install windows?
Each window takes about 30 minutes to install depending on the type of window. However, the window installation can take two days or more if you need to have a lot of windows installed.
Should I replace my windows all at once?
If you're upgrading your windows to get more efficient windows, replacing all of your windows together is the only way to see a noticeable difference. However, if you have just a few windows that are damaged or drafty, you can replace just those.
