How Installing Energy-Efficient Windows in Penn Saves You Money
When you upgrade to energy-efficient windows, you may see a few perks, including:
- Protect your investment: If you have an older home, your windows are most likely outdated. Upgrading your windows can make your home more comfortable and also help increase the value of your house if you decide to sell.
- Save money on energy bills: Since energy-efficient windows lower the amount of energy needed to heat or cool your home, the switch can help you save about $293 annually on your energy bills in Penn.
- Decrease 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.
- Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent damage from the sun's UV rays to your floors, carpets and furniture.
Estimated Cost of Window Replacement in Penn
When researching window installation, each company offers varying services and prices. Let’s go over some typical costs and services.
How Much Do New Windows Cost?
Even though the typical cost to replace a single window is about $600, it can range anywhere from $200 to $1,200. But costs will differ considerably depending on the quality of your products, the current condition of your home, your location and the number of windows you need. Many window companies also offer replacement door installations and other add-ons like coating, baths, shutters and more. These extra services will increase overall project costs.
Whether or not you pick energy-efficient windows is another factor that will affect the cost. These will usually cost more than other windows, but on the other hand, you can save about $293 a year on your energy bills in Penn.
We recommend requesting free quotes from several window companies to find the one that works best for your budget.
What Services do Window Installers Offer?
Generally, there are two kinds of window replacement services companies offer: full-frame and pocket installations.
Full-frame installations are necessary when you want a new style or your window has a lot of rot or deterioration. With this service, your installers will replace the total window, including the trim, frame and sill. Pocket installations are simpler and won’t cost as much because they entail merely replacing the window within its existing frame. But if the frame has any damage, you may need a full-frame installation instead.
Your window installation company can advise you on the best type for your project. In Penn, the choice will mostly be based on the efficiency of your home and how old your existing frames are.

How We Choose the Best Window Installers in Penn
In our hunt to find the most reliable, eco-friendly window installers in Penn, the EcoWatch Reviews team chose the above companies as the best window installation companies in the city. We have evaluated the best window replacement companies in Penn mostly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows have been shown to reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
This one is self-explanatory, but we’ve chosen to highlight window installers that serve Penn so you can find the right window installation company near you.
Work Quality
We’re certain that you’re looking for professionals who do a great job installing windows. We’ve vetted each installer included on this list to make sure its contractors are well-qualified and that the company has received tons of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed patterns in recent online reviews to determine the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it indicates the quality of services across nearly every category, including professionalism, quality of installation, quality of parts, warranty, cost and more.
Cost
This one is a give-and-take: as with most services, cheap window companies may not provide the most quality service. On the other hand, we want to make sure we’re highlighting companies that provide a wide range of price and financing options so they’re accessible to most homeowners.
Warranty
As discussed previously, windows are a hefty investment, so you’ll want to be certain that investment is well protected. Window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to Penn’s climate, homeowners will want to mitigate rot, low efficiency and water damage. We factored in local experience to reflect the ability of Penn window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Penn, PA Window Replacement FAQs
How much should window installation cost?
The national average cost to replace a window is about $600 but can range from $200 to $1,200, based on a variety of factors. The price is usually dependent on the location of your property, the type and material of the window and the size of the window. Also, remember that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.
What are the different types of windows?
There are several different types of windows you can get for your house, including transom windows, casement windows, slider windows, bay windows, picture windows, double-hung and single-hung windows and awning windows.
What do window installers do?
Window installation professionals go to your property to remove your old windows and replace them with new ones. Some providers install products sold by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation is done.
When is the best time of year to replace windows?
Replacement windows can be installed during any season, but autumn might be best. Regardless of when you install them, the contractors will take steps to make sure that too much hot or cold air doesn’t get into your home, so the temperature outside isn’t necessarily a big factor. What’s most important is that the weather should be dry.
How often do you need to replace your windows?
Windows generally last around 20 to 30 years, but anytime you notice damage on your windows, it’s a good time to have an expert take a look at them to determine if they are in need of a repair or replacement.
