How Installing Energy-Efficient Windows in Castle Shannon Saves You Money
Energy-efficient windows can benefit you in more than one way. Here are a few reasons you may want to make the switch:
- Save on power bills: Because energy-efficient windows decrease how much energy you need to heat or cool your home, the switch can help you save about $313 annually on your energy bills in Castle Shannon.
- Better temperature control in your home: When you live in a place like Castle Shannon where the summers can be quite hot, you usually have to rely on your air conditioner to keep your home cool. Energy-efficient windows can cut back on how much cool air is lost through your windows when cooling your home.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out damaging UV rays, reducing fading of your furniture, carpet and other valuables.
- Decrease your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% when you install Energy Star certified windows. In Castle Shannon, that's about 467 pounds per year on average.
Estimated Cost of Window Replacement in Castle Shannon
Let's take a look at the cost of window replacement and the types of services you may need for your home.
How Much Do New Windows Cost?
Generally, Castle Shannon homeowners can anticipate their window replacements to range from $250 to $1,200. The average cost sits at about $600. This is because the cost of window installations depend on a variety of factors specific to your home, including the size, material and number of windows you need to replace, as well as where your property is located.
It's also worth bearing in mind that energy-efficient windows will typically cost more upfront, but Energy Star predicts that upgrading the windows on your Castle Shannon home translates to an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. The amount of money you'll save by upgrading to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
Requesting free quotes from several providers is the best way to find out which one is right for you.
What Services do Window Installers Offer?
The first question to ask yourself when planning to replace your windows is: Should you get a full-frame installation or a pocket installation?
Full-frame installations involve replacing the complete window, including the trim, frame and sill. Full-frame installations are necessary when you want to change the style of your windows or your window has significant damage. Because full-frame installations are more involved, they will raise the overall cost. A pocket installation entails replacing a window without replacing the frame. So, instead of tearing 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 installation company can recommend the best type for your project. In Castle Shannon, the decision will mostly be influenced by the efficiency of your home and how old your existing frames are.

How We Choose the Best Window Installers in Castle Shannon
EcoWatch is different from other reviewers because we evaluate these companies through a sustainability lens. Along with energy efficiency, we assessed each installer and ranked them using the following methodology:
Service Area
Because this is a guide for Castle Shannon, we only included companies that provide services to the city. There are certainly other reputable providers that didn't make the list because of the low odds that they would serve the average homeowner in Castle Shannon.
Work Quality
When selecting new windows, the quality and breadth of services can often play just as important of a role in insulation and performance as the type of window you choose. We do give window installers more points if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
Another self-explanatory yet very important review factor is customer feedback. If most customers don't have good feedback about their experience with a certain window installation company, it won't be featured on EcoWatch.
Cost
This one is a give-and-take: as with most services, cheap window installation companies won't always provide the most quality service. Still, 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 considerable investment, so you'll want to make sure that investment is protected. Window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have been in the industry for a while. Window installers that have more years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
Castle Shannon, PA Window Replacement FAQs
What is the typical cost to install new windows?
The national average cost to install a single window is about $600 but can range from $200 to $1,200, depending on several factors. The price is often 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 hundreds of dollars 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 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 with the blue Energy Star certification — that means they're certified energy-efficient by the U.S. Department of Energy.
Can you replace your own windows?
If you're handy and know how to replace a window, you may be able to install your own windows. But if you don't have the time or experience, we recommend getting a professional to do it for you.
How long does window installation usually take?
Since the average installation time of a window is 30 minutes, around 16 windows can be installed in a typical 8-hour work day.
