How Installing Energy-Efficient Windows in Penn Saves You Money
By upgrading to energy-efficient windows, you and your family can enjoy several benefits, such as:
- Decrease your carbon footprint: Decreasing how much energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 467 pounds.
- Protect your investment: Upgrading your windows is an important part of maintaining your property and its real estate value, especially if your home is on the older side.
- Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
- Save money on energy bills: The Department of Energy estimates that heat gained or lost via windows accounts for about 25-30% of residential energy use. Switching to energy-efficient windows can help reduce that number, which helps you save more on your bills.
Estimated Cost of Window Replacement in Penn
When looking into window installation, each company offers varying services and prices. Let's go over some typical costs and services.
How Much Do New Windows Cost?
The typical cost to install a single window is about $600 but can range anywhere from $200 to $1,200. These amounts vary depending on specific characteristics of your installation, such as number of windows, material, size, type, the location of your home and more.
Whether or not you opt for energy-efficient windows is another factor that will influence the cost. These will typically cost more than other windows, but on the other hand, you can save about $293 a year on your energy bills in Penn.
Another factor that affects the overall cost is the material of the frame you pick. Aluminum frames are usually 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 and cost somewhere between the other two.
What Services do Window Installers Offer?
Generally, there are two kinds of window replacement services companies provide: full-frame and pocket installations.
Full-frame installations are usually recommended when you want to change the style of your windows or your window has significant deterioration. With this service, your installers will replace the total window, including the frame, trim and sill. A pocket installation means replacing a window within the existing frame, which tends to be less expensive than a full-frame installation.
Your window replacement company will be able to help you understand what's best for your needs. In Penn, the decision will mostly depend on how old your home is and if there's any moisture damage. Wood can decay if not properly maintained over the years, so it's good to have a professional check your frames and window sills.

How We Choose the Best Window Installers in Penn
In our search to find the most reliable, eco-friendly window installers in Penn, EcoWatch chose the above companies as the top window installation companies in the city. We've evaluated the top window installation companies in Penn primarily based on energy efficiency, as it's the most sustainable option and the best one for homeowners. Energy-efficient windows have been shown to cut your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
Since this is a guide for Penn, we paid more attention to companies that cover the city. There are other reputable providers that didn't make the list because of the low odds that they would serve the average homeowner in Penn.
Work Quality
We're willing to bet that you're not looking for a company to do a shoddy job installing windows. We've vetted each installer included on this list to make sure its technicians are well-qualified and that the company has gotten a lot of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed patterns in recent customer feedback to find the companies with the most customer satisfaction. Customer satisfaction may be the most important factor, as it reflects the quality of services across most other categories, including cost, quality of installation, professionalism, warranty, quality of parts and more.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers want to keep costs low when possible. When analyzing the prices of providers, we gave higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
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
Because of Penn's climate, homeowners need to be wary of rot, water damage and low efficiency. 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 one window is around $600 but can range from $200 to $1,200, depending on a variety of factors. The price is often dependent on the size of the window, the type and material of the window and the location of your property. Also, remember that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.
Which kind of window is the best?
A window's energy efficiency is influenced by a variety of factors, such as the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are often the most energy-efficient since they are certified by the U.S. Department of Energy.
Do I really 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 a professional. The window installation process is complex and can take anywhere from four to six hours for a single window. Although it's tempting to try to save money by doing it yourself, hiring a professional is a faster, more efficient and much safer alternative.
What time of year is the best time to replace my windows?
Replacement windows can be installed at any time, but warmer weather is typically better. 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 house, so the temperature outside doesn't necessarily matter that much. What's most important is that the weather should be dry.
How often do you need to replace windows?
Windows usually last about 20 to 30 years, but anytime you notice damage on your windows, it's a good idea to have an expert take a look at them to determine if they need any repairs or replacements.
