How Installing Energy-Efficient Windows in Greensburg Saves You Money

There are quite a few perks of switching to energy-efficient windows. A few reasons you may want to consider making the switch include the following:

  • Protect your investment: If you have an older home, your windows are most likely outdated. Upgrading your windows can make your home more comfortable and also help increase the value of your home if you decide to sell.
  • Save money on energy bills: After you upgrade to energy-efficient windows, you can expect a reduction in your bills by about 12% since you’ll require less energy to heat or cool your home.
  • Protect your valuables from fading: When you upgrade to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will be protected from fading due to their ability to filter out harmful UV rays.
  • Reduce your carbon footprint: By using less energy after you switch to Energy Star certified windows, you’ll also be lowering your carbon dioxide emissions by about 12%, according to Energy Star.

Estimated Cost of Window Replacement in Greensburg

Windows come in varying shapes and sizes, so costs and services will differ tremendously. Here are the typical costs and the primary services that you can find from window installers.

How Much Do New Windows Cost?

According to our market research, the average cost to replace a single window is about $600. However, window installation costs can range from $200 to $1,200 for each window. Costs will vary significantly depending on the number of windows you need, your location, the quality of your products and the current condition of your home. A lot of window companies also offer replacement door installations and other add-ons like baths, shutters, coating and more. These extra services will increase overall project costs.

With windows, efficiency is one of the most important factors for many homeowners. High efficiency windows may cost more off the bat, but by increasing the efficiency of your home — especially during the summer and winter — they can provide many years of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Greensburg homeowners $293+ per year after replacing single-pane windows.

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

Because of Greensburg’s climate, homeowners need to be wary of low efficiency, rot and water damage. 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

How much should window installation cost?

The national average cost to install a single window is about $600 but can range from $200 to $1,200, depending on a variety of factors. The price is often influenced by the type and material of the window, the location of your property and the size of the window. Also, remember that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.

Which kind of window should I get?

A window’s energy efficiency is affected by several factors, such as the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are often the most energy-efficient and are certified by the U.S. Department of Energy.

When do I need to use a window installation company?

You should use a window installation company whenever you need to upgrade your windows. Installing windows is a complicated process that can be difficult to do on your own, so it’s best left to the professionals.

Should I replace all my windows at once?

If you want to get more efficient windows and save money on your energy bills, replacing all your windows at once is the only way to gain that benefit. On the other hand, if you have only one or two windows that are damaged or leaky, you can replace just those.
