How Installing Energy-Efficient Windows in Upper St Clair Saves You Money
Energy-efficient windows can offer benefits in more than one way. Here are a few reasons you may want to make the switch:
- Save on energy bills: Because energy-efficient windows decrease how much energy you need to heat or cool your home, they can help you save about $313 annually on your energy bills in Upper St Clair.
- 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.
- Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Updating your windows can make your home more comfortable and also help increase the value of your home if you decide to sell.
- Reduce your carbon footprint: In Upper St Clair, you can cut your indirect greenhouse gas emissions by about 467 pounds per year when you upgrade to energy-efficient windows.
Estimated Cost of Window Replacement in Upper St Clair
Let's take a look at the cost of window replacement and the kinds of services you may need for your home.
How Much Do New Windows Cost?
According to our market research, the typical cost of replacing a single window is around $600. However, window installation costs can range from $200 to $1,200 for each window. These numbers are based on the specifics of your installation, like type, size, number of windows, the location of your home, material and more.
Keep in mind that energy-efficient windows may have a higher price, but Energy Star estimates the upgrade will save you between $101 and $583 per year when installing single-pane windows and between $27 and $197 per year when installing double-pane, clear glass windows. Your exact savings will vary depending on your local climate, energy rates and individual home characteristics.
How much your window installation costs will also vary based on the type of window material you choose for the frames. Wood windows are generally the most expensive, though it depends if they are completely wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are more efficient.
What Services do Window Installers Offer?
When it comes to window replacements, in general there are two kinds that your provider will have: full-frame and pocket installations.
Full-frame installations require replacing the full window — the sill, frame, trim and all. These are typically done when you want to change the style of your window or when it has a great amount of deterioration. Full-frame installations require more time and labor and will increase overall costs. A pocket installation means replacing a window within the existing frame, which is usually cheaper than a full-frame installation.
Your window installation company will be able to advise you on the best type for your project. In Upper St Clair, the decision will mostly be influenced by the efficiency of your home and how old your existing frames are.

How We Choose the Best Window Installers in Upper St Clair
In our hunt to find the most reliable, eco-friendly window installers in Upper St Clair, EcoWatch assessed many companies before landing on these. Along with energy efficiency, we evaluated each installer and assigned rankings using the following methodology:
Service Area
This one is self-explanatory, but we've chosen to highlight window installation companies that serve the Upper St Clair area so you can find the right window installation company near you.
Work Quality
We're willing to bet that you're looking for a company to do a great job installing windows. We've vetted each installer featured in our guide to ensure its contractors are well-qualified and that the company has received lots of positive customer feedback to vouch for its service.
Customer Reviews
Another self-explanatory yet very important review factor is customer feedback. If most customers don't have nice feedback about their experience with a certain window installation company, you won't see it featured on EcoWatch.
Cost
This one is a give-and-take: as with most services, cheap window companies won't always provide the most quality service. Still, we want to ensure we're highlighting companies that offer a spectrum 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 provide lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to Upper St Clair's climate, homeowners need to be wary of water damage, rot and low efficiency. We factored in local experience to reflect the ability of Upper St Clair window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Upper St Clair, PA Window Replacement FAQs
What is the typical cost to install 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 several factors. The price is usually dependent on 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 initially but can save you a decent amount of money a year in energy bills.
What type of window is the most energy-efficient?
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. To be sure you'll have the most energy-efficient windows, look for models that have the blue Energy Star certification — they're certified energy-efficient by the U.S. Department of Energy.
What services do window replacement companies offer?
Window installers will do the entire process — from replacing old windows with brand new ones to cleaning up after the windows have been put in place. Additionally, some companies offer window manufacturing, customization and repairs.
What time of year is a good time to replace my windows?
Though you can install windows any time of year, warmer weather is usually better for replacing windows. In addition, it shouldn't be raining, because rain can make the installation more difficult.
When is it time to replace your windows?
Windows usually last about 20 to 30 years, but anytime you see damage on your windows, it's a good idea to have an expert take a look at them to determine if they are in need of a repair or replacement.
