How Installing Energy-Efficient Windows in Bethel Park Saves You Money
By upgrading to energy-efficient windows, you can take advantage of several benefits, such as:
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only insulate your home better, but also filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
- Protect your investment: When your home is on the older side, your windows could also be outdated or leaky. Keeping your windows up to date is an important part of maintaining your property and its real estate value.
- Save money on power bills: After you install energy-efficient windows, you can expect a reduction in your bills by about 12% because you’ll use less energy to heat or cool your home.
- Reduce your carbon footprint: Decreasing the amount of energy you use also lowers your carbon emissions. You could reduce it by 467 pounds per year on average.
Estimated Cost of Window Replacement in Bethel Park
Let’s take a look at the cost of installing new windows and the types of services offered by installers.
How Much Do New Windows Cost?
According to our research, the average cost of installing a single window is about $600. However, window installation costs can range from $200 to $1,200 a window. But costs vary considerably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also provide door installations and replacements, which will add extra costs to your project.
Whether or not you pick energy-efficient windows is another factor that will affect the cost. These will almost always cost more than other windows, but on the other hand, you can save about $313 a year on your energy bills in Bethel Park.
The cost of your window installation will also vary based on the type of window material you choose for the frames. Wood windows are typically the most expensive, but it depends on whether they are 100% 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?
There are generally two kinds of window installation services: full-frame and pocket installations.
Full-frame installations are necessary when you want to change the style of your windows or your window has significant rot. With this service, your installers will replace the total window, including the trim, frame and sill. Pocket installations (or retrofits) involve installing a new window within the existing frame, which makes pocket installations less labor-intensive and costly. But, if the frame has any damage or rot, you will likely need a full-frame installation instead.
If you’re still trying to decide which kind of installation you need, you can ask your provider and get their recommendation. The decision mostly is influenced by the age of your window frames and if there’s any damage present.

How We Choose the Best Window Installers in Bethel Park
In our search to make your home improvements easier and more eco-friendly in Bethel Park, the EcoWatch team evaluated many companies before deciding on these. Along with energy efficiency, we assessed each installer and assigned rankings using the following methodology:
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 best window installation company near you.
Work Quality
When selecting new windows, the quality and breadth of services often plays just as important of a role in insulation and performance as the type of window you choose. We do rate window installers higher if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
We analyzed trends in recent customer feedback to find the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction might be the most important factor, as it indicates the quality of services across most other categories, including cost, quality of parts, warranty, quality of installation, professionalism and more.
Cost
This one is a give-and-take: similar to most services, cheap window installation companies won’t always provide the highest quality service. Still, we want to ensure we’re highlighting companies that offer a wide range of price and financing options so they’re accessible to most homeowners.
Warranty
Protecting your investment in new windows is important. That’s why window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have been in the industry for quite some time. Window installation companies that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Bethel Park, PA Window Replacement FAQs
How much should window installation cost?
The national average cost to replace a window is around $600 but can range between $200 and $1,200, based on a variety of factors. The price is usually influenced by the type and material of the window, the location of your property and the size of the window. Also, bear in mind that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.
What are the kinds of windows?
There are several different types of windows you can get for your home, including transom windows, casement windows, bay windows, picture windows, double-hung and single-hung windows, slider windows and awning windows.
When do I need to use a window installation company?
Unless you have experience with home improvement projects and have the time to replace your own windows, we recommend hiring the pros. The window installation process is quite involved 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 alternative.
What time of year is a good time to replace my windows?
Even though you can install windows any time of year, warmer weather is typically better for installing replacement windows. Additionally, it shouldn’t be raining, because rain can make the installation harder.
How long does window installation generally take?
Because the average installation time is 30 minutes per window, about 16 windows can be installed during a typical 8-hour work day.
