How Installing Energy-Efficient Windows in East Pennsboro Saves You Money
Upgrading to energy-efficient windows can improve the comfort of your home and help you save on power bills. Here are more details about how upgrading your windows could benefit you:
- Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Upgrading your windows can improve the insulation in your home and also help raise the value of your house if you decide to sell.
- Save money on electricity bills: According to the Department of Energy, heat gained or lost through windows accounts for around 25-30% of residential energy use. Installing energy-efficient models can help reduce how much energy is used in your home, therefore saving you about 12% more on your bills.
- Reduce your carbon footprint: Reducing how much energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 286 pounds.
- Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.
Estimated Cost of Window Replacement in East Pennsboro
Let’s take a look at the cost of installing new windows and the kinds of services offered by installers.
How Much Do New Windows Cost?
According to our market research, the national average cost of installing a single window is around $600. However, window installation costs can range from $200 to $1,200 for each window. These figures vary based on specific characteristics of your installation, including the location of your home, size, type, number of windows, material and more.
It’s important to bear in mind that windows with the best efficiency may cost more initially but can save you hundreds of dollars by lowering your energy bills. Investing in Energy Star certified windows can save East Pennsboro homeowners $310+ a year when replacing single-pane windows.
How much your window installation costs will also vary depending on the type of material you choose for the frames. Wood windows are usually the most expensive, although it depends on whether they are solid wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit 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.
A full-frame installation replaces the entire window, such as the windowsill, frame, trim and the window panes. Because this kind of installation requires more time, it will be more expensive than a pocket installation. Pocket installations are on the simpler end and won’t carry as large a bill, as they entail simply replacing the window within its existing frame. But if the frame has any damage or deterioration, you may need a full-frame installation instead.
If you’re still debating which kind of installation you need, you can talk to your installer and get their recommendation. The decision mostly is influenced by how old the frames are and if there’s any damage present.

How We Choose the Best Window Installers in East Pennsboro
In our hunt to find the most reliable, eco-friendly window installers in East Pennsboro, the EcoWatch team assessed dozens of companies before deciding on these. We have assessed the best window installation companies in East Pennsboro mostly based on energy efficiency, as it’s the most sustainable option and the best one for homeowners. Energy-efficient windows can reduce your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
Because this is a guide for East Pennsboro, we only included companies that provide services to the city. There are certainly reputable providers that didn’t make the cut because of the low odds that they would serve the average homeowner in East Pennsboro.
Work Quality
We’re willing to bet that you’re looking for professionals who do a great job installing windows. We’ve vetted each company included on this list to ensure its contractors are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.
Customer Reviews
Customer feedback is another super important review factor. If the majority of customers don’t have good things to say about their experience with a certain company, you won’t see it featured on EcoWatch.
Cost
This one is a give-and-take: similar to other services, cheap window installation companies are not going to provide the highest quality service. On the other hand, 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 have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of East Pennsboro’s climate, homeowners will want to mitigate low efficiency, rot and water damage. We factored in local experience to reflect the ability of East Pennsboro window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
East Pennsboro, PA Window Replacement FAQs
How much should a window install cost?
The typical cost of replacing one window can range from $450 to $650. There are many factors that influence how much it costs, which include styles and sizes of windows, the materials used in designing the windows, how energy-efficient the windows are, local labor costs, your property’s location and the number of windows.
What type of window is the most energy-efficient?
Generally, double-pane windows will be more efficient than single-pane windows and windows that don’t open will be more efficient than windows that do. If you want to be sure you’re getting 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 do window installers do?
Window installation companies will do the entire process — from replacing your old windows with brand-new ones to cleaning up after the windows have been put in place. Additionally, a lot of companies offer window manufacturing, customization and repairs.
When is the best time of year to replace windows?
Although you can install windows any time of year, warmer weather is often better for replacing windows. In addition, the weather should be dry, because rain can make the installation harder.
How often do you need to replace windows?
Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, then they should probably be replaced. Other than that, if your windows have any damage on them, or they have become difficult to operate, they may need to be replaced.
