How Installing Energy-Efficient Windows in Penn Saves You Money
Energy-efficient windows can provide benefits in more than one way. Here are some reasons you may want to consider making the switch:
- Reduce your carbon footprint: Decreasing how much energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by 467 pounds per year on average.
- Better temperature control in your home: Living in a very cold place like Penn can often mean relying on your heater to keep your home cool. Energy-efficient windows can reduce the amount of heat lost through your windows when heating your home.
- Better temperature control in your home: When you live in a place like Penn where the summers can get quite hot, you usually need to rely on your air conditioner to keep your home cool. Energy-efficient windows can decrease how much cool air is lost through your windows when cooling your home.
- Protect your investment: If your home is on the older side, your windows are most likely outdated. Upgrading your windows can make your home more comfortable and also help raise the value of your property if you decide to sell.
Estimated Cost of Window Replacement in Penn
Windows come in all shapes and sizes, so costs and services will differ tremendously. Here are the average costs and the primary services that you can find from window installation companies.
How Much Do New Windows Cost?
Though the average to install one window is around $600, it can range from $200 to $1,200. How much it will cost you depends on several factors, such as material, size, type, the location of your home, number of windows and more.
Bear in mind that energy-efficient windows may cost more upfront, but Energy Star predicts the upgrade will save you between $101 and $583 per year when you replace single-pane windows and between $27 and $197 per year when you replace double-pane, clear glass windows. Your 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 typically the most expensive, though it depends if 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?
When considering window replacements, there are typically two types that your provider will have: full-frame and pocket installations.
A full-frame installation replaces the total window, including the windowsill, frame, trim and the window panes. As this kind of installation requires more time, it will cost more than a pocket installation. A pocket installation involves replacing a window without replacing the frame. So, instead of taking out the whole unit and rebuilding it, the window installer will just slide the replacement window (also called a retrofit or insert window) into the frame.
Your window installer can help you decide which type of installation you should get.

How We Choose the Best Window Installers in Penn
In our search to find the most reliable, eco-friendly window installers in Penn, EcoWatch assessed dozens of companies before landing on these. We have reviewed the top window installers in Penn mainly based on their energy efficient offerings, 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 installation companies that serve Penn so you can find the best window installation company near you.
Work Quality
When selecting new windows, the quality and range of services can often play just as important of a role in overall efficiency and performance as the brand of window you get. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
We analyzed trends in recent online reviews to determine the companies with the most customer satisfaction. Customer satisfaction may be the most important factor, as it indicates the quality of services across most other categories, including quality of installation, professionalism, cost, quality of parts, warranty and more.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers would like 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, windows are a substantial investment, so you'll want to make sure that investment is well protected. Window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of Penn's climate, homeowners need to be wary of rot, low efficiency and water damage. We factored in local experience to reflect the ability of Penn window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Penn, PA Window Replacement FAQs
How much should a window install cost?
The national average cost of installing a 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.
Which kind of window is the best?
Generally, double-pane windows are more efficient than single-pane windows and windows that do not open are more efficient than windows that do. If you want to be sure you'll have the most energy-efficient windows, look for models with the blue Energy Star certification — that means they're certified energy-efficient by the U.S. Department of Energy.
When do I have to use a window installation company?
You should use a window installation company whenever you want new windows. Installing windows is a complex process that can be difficult and time-consuming, so it's best handled by the professionals.
How long does window installation generally take?
Each window takes about 30 minutes to install depending on the type of window. However, the window installation can take two days or more if you have a lot of windows that must be installed.
