Greensburg Window Cost Calculator

Calculate how much you can expect to pay for window installation and replacement in Greensburg, PA using our customized window cost calculator.

Estimated Window Cost:
161 homeowners have requested a free estimate in the last 3 days.

Estimates will vary based on window dimensions and other unique factors to your home. Getting in touch with a local window installer is the best way to get an accurate cost estimate for your home.

How Installing Energy-Efficient Windows in Greensburg Saves You Money

By switching to energy-efficient windows, you and your family can benefit in several ways, such as:

  • Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its real estate value, especially if you have an older home.
  • Save on energy bills: According to the Department of Energy, heat gained or lost through windows makes up around 25-30% of residential energy use. Replacing your windows with energy-efficient models can help decrease that number, therefore saving you about 12% more on your bills.
  • 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.
  • Reduce your carbon footprint: Decreasing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 467 pounds.

Estimated Cost of Window Replacement in Greensburg

Each window replacement company provides varying services and has varying prices depending on a few factors.

How Much Do New Windows Cost?

Generally, Greensburg homeowners can expect their window installations to range from $250 to $1,200. The most common installations sit at approximately $600. But costs will differ considerably based on the number of windows you need, the quality of your products, your location and the current condition of your home. Many window companies also offer replacement door installations and other add-ons like coating, shutters, baths and more. These extra services will increase your overall project costs.

Whether or not you choose energy-efficient windows is another factor that will affect the cost. These will usually cost more than other windows, but on the other hand, you can save about $293 a year on your energy bills in Greensburg.

We advise requesting free quotes from multiple window installation companies to find the right windows and the company that works best for you.

What Services do Window Installers Offer?

When considering window installations, in general there are two kinds that your provider will offer: full-frame and pocket installations.

Full-frame installations entail replacing the full window, including the trim, frame and sill. You most likely need a full-frame installation when you want a new style or your window has significant deterioration. These installations are more involved and will raise the total cost. A pocket installation involves installing a new window without replacing the frame. So, instead of removing the whole unit and rebuilding it, the window installer will just slide the replacement window (also called a retrofit or insert window) into the frame.

If you’re unsure which window installation service you should get, your installer should be able to assist you. Typically, the choice 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 reviews are different from other reviews, as we evaluate these companies through a sustainability lens. Along with energy efficiency, we analyzed window companies all across the state and assigned rankings 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 best window installation company near you.

Work Quality

We’re certain that you’re looking for a company to do a great job installing windows. We’ve vetted each installer featured in our guide to make sure its technicians are well-qualified and that the company has received lots of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed trends in recent online reviews to find the companies with the most consistent customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it reflects the quality of services across most other categories, including warranty, professionalism, quality of parts, cost, quality of installation and more.

Cost

Cheaper windows don’t necessarily mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing providers’ prices, we awarded higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

As discussed, windows are a considerable investment, so you’ll want to be certain that investment is protected. Window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Due to Greensburg’s climate, homeowners will want to mitigate water damage, rot and low efficiency. We factored in local experience to reflect the ability of Greensburg window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.

Greensburg, PA Window Replacement FAQs

What is the typical cost to install windows in a home?

The typical cost to install one window can range from $450 to $650. There are several factors that influence how much it costs, such as local labor costs, your property’s location, styles and sizes of windows, how energy-efficient the windows are, the materials used in designing the windows and the number of windows.

Which kind of window should I get?

Generally, double-pane windows are more efficient than single-pane windows and windows that do not open will be 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 — that means they’re certified energy-efficient by the U.S. Department of Energy.

When do I need to use a window installation company?

Unless you have home repair skills and have the time needed to replace your own windows, we recommend hiring a professional installer. The process of installing windows is complex and can take anywhere from four to six hours for a single window. Although it’s tempting to try to do it yourself to save money, hiring a professional is a faster, more efficient and safer option.

Should I replace my windows all at once?

If you’re upgrading your windows to get more efficient windows, replacing all the windows together is the only way to see a noticeable difference. However, if you have just one or two windows that are broken or drafty, you can replace just those.
