How Installing Energy-Efficient Windows in South Fayette Saves You Money
Energy-efficient windows can provide benefits in several ways. Here are some reasons you may want to take the plunge and make the switch:
- Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its value, particularly if you have an older home.
- Save on energy bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of household energy use. Replacing your windows with energy-efficient models can help reduce how much you have to pay, therefore saving you about 12% more on your bills.
- Reduce your carbon footprint: Reducing how much energy you use also lowers your carbon emissions. You could reduce it by 467 pounds per year on average.
- Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.
Estimated Cost of Window Replacement in South Fayette
Each window installer offers varying services and has different prices based on several factors.
How Much Do New Windows Cost?
Generally, South Fayette homeowners can expect their window installations to range from $250 to $1,200. The most common installations sit at around $600. These amounts are based on the specifics of your installation, like material, type, size, number of windows, the location of your home and more.
Whether or not you want energy-efficient windows is another factor that will determine the cost. These will typically cost more than other windows, but on the other hand, you can save about $313 a year on your energy bills in South Fayette.
Costs will also vary depending on the material you want for your window frames. Aluminum frames are the least expensive. They’re sturdy, light and maintenance-free, but offer poor insulation. Vinyl frames are a bit more expensive and provide good insulation. Composite frames made from wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They’re also aesthetically pleasing and provide decent insulation for your home.
What Services do Window Installers Offer?
The first step of a window replacement is to figure out whether you need a full-frame or pocket installation.
A full-frame installation is a total window replacement. This service involves removing the old window, the windowsill, and the exterior and interior trim. It also involves additional materials, such as insulation and drip edges, which raise the total cost of the project. It’s also worth noting that it’s not uncommon for homeowners to have to touch up the paint around the window after a full-frame installation. Pocket installations (also known as retrofits) are when you replace a window while leaving the existing frame. Pocket installations are on the simpler end and won’t cost as much, but you can’t do this type of installment if you have any pre-existing rot or water damage.
Your window installation company can advise you on the best type for your project. In South Fayette, the choice will mostly be influenced by how much damage there is currently and the age and condition of your existing frames.

How We Choose the Best Window Installers in South Fayette
In our hunt to make your home improvements easier and more eco-friendly in South Fayette, the EcoWatch team evaluated dozens of companies before deciding on these. Along with energy efficiency, we evaluated each installer and assigned rankings based on the following methodology:
Service Area
This one is self-explanatory, but we’ve chosen to highlight window installers that serve South Fayette so you can find a quality 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 in our guide to make sure its technicians are well-qualified and that the company has gotten plenty of positive customer feedback to vouch for its service.
Customer Reviews
Customer feedback is another very important review factor. If the majority of customers don’t have good things to say about their experience with a certain installer, it won’t be featured on EcoWatch.
Cost
Cheaper windows don’t necessarily mean better windows, but we know many of our readers try 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
As discussed previously, windows are a considerable investment, so you’ll want to make sure that investment is protected. Window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of South Fayette’s climate, homeowners need to be wary of water damage, rot and low efficiency. We factored in local experience to reflect the ability of South Fayette window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
South Fayette, PA Window Replacement FAQs
How much should window installation cost?
The national average cost to replace a 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 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 hundreds of dollars a year in energy bills.
Which kind of window is the best?
A window’s energy efficiency is influenced by several factors, including the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are usually the most energy-efficient and are certified by the U.S. Department of Energy.
Do I really need to use a window installation company?
You should hire a window installation professional whenever you need to upgrade your windows. Installing windows is a complex process that can take a lot of time, so it’s best handled by the professionals.
When is the best time of year to replace windows?
Replacement windows can be installed during any season, but autumn might be best. No matter when you install them, the contractors will take steps to ensure that too much hot or cold air doesn’t get into the home, so the temperature outside doesn’t necessarily matter that much. What’s most important is that the weather should be dry.
