How Installing Energy-Efficient Windows in Pittsburgh Saves You Money
When you upgrade to energy-efficient windows, you may see some perks, including:
- Save on electricity bills: According to the Department of Energy, heat gained or lost through windows accounts for around 25-30% of residential energy use. Upgrading to energy-efficient models can help reduce how much energy is used in your home, therefore saving you about 12% more on your bills.
- Decrease your carbon footprint: By using less energy after you upgrade to energy-efficient windows, you’ll also be cutting your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
- Protect your investment: When you have an older home, your windows could also be outdated or drafty. Upgrading and repairing your windows is an important part of maintaining your property and its value.
Estimated Cost of Window Replacement in Pittsburgh
Each window replacement company provides varying services and has different costs based on several factors.
How Much Do New Windows Cost?
On average, homeowners in Pittsburgh can expect that most window installations will cost between $250 and $1,200, with the most common installations sitting at around $600. These figures vary depending on the specifics of your installation, such as size, material, type, the location of your home, number of windows and more.
Whether or not you want to install energy-efficient windows is another factor that will influence the cost. These will usually cost more than other windows, but on the other hand, you can save about $313 a year on your energy bills in Pittsburgh.
Another factor that influences the overall cost is the material of the frame you select. Aluminum frames are generally the least pricey and are sturdy and light, but they offer poor insulation. On the other hand, wood frames cost the most, as they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.
What Services do Window Installers Offer?
In general, there are two types of window replacement services companies provide: full-frame and pocket installations.
A full-frame installation replaces the full window, such as the sill, frame, trim and the window panes. Because this kind of installation is more involved, it will be more expensive than a pocket installation. Pocket installations are simpler and won’t cost as much, as they entail merely replacing the window within its existing frame. But if the frame has any damage or rot, you may need a full-frame installation instead.
Your window installer can help you decide which type of installation you should get.

How We Choose the Best Window Installers in Pittsburgh
In our hunt to find the most reliable, eco-friendly window installers in Pittsburgh, the EcoWatch team examined dozens of companies before deciding on these. We’ve assessed the best window installers in Pittsburgh primarily based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows can lower energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
This one is self-explanatory, but we’ve chosen to highlight window installers that serve a wide variety of states and cities 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 company 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
Customer feedback is another very important review factor. If the majority of customers don’t have positive feedback about their experience with a certain window installation company, it won’t be featured on EcoWatch.
Cost
Cheaper windows certainly don’t mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing the prices of providers, we gave higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
As discussed, windows are a hefty investment, so you’ll want to be certain 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
Last but not least, we like to see companies that have been in the industry for quite some time. Window installers that have more years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
Pittsburgh, PA Window Replacement FAQs
How much does window installation cost?
The national average cost to install a single window is about $600 but can range between $200 and $1,200, based on several factors. The price is generally dependent on the size of the window, the type and material of the window and the location of your property. Also, bear in mind that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.
Which type of window is the best?
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 get the most energy-efficient windows, look for models that have the blue Energy Star certification attached to them — they’re certified energy-efficient by the U.S. Department of Energy.
What services do window replacement companies do?
Window installers go to your home to remove your old windows and replace them with new ones. Some providers install products distributed by other companies, whereas others install their own windows. The installer will also clean up after the installation.
Should I replace my windows all at the same time?
If your windows are greater than 20 years old, it’s most likely time to replace all of them. By that point, they are typically less efficient, draftier and/or more damaged than new windows. Replacing your windows all at the same time will involve less paperwork and less stress.
