How Installing Energy-Efficient Windows in Charlestown Saves You Money
Upgrading to energy-efficient windows can help improve the comfort of your home and help you save on energy bills. Here are more details about how upgrading your windows could help you:
- Reduce your carbon footprint: In Charlestown, you can cut your indirect greenhouse gas emissions by about 286 pounds per year once you upgrade to energy-efficient windows.
- Protect your investment: If you have a relatively old home, your windows are most likely in need of replacement. Updating your windows can improve the insulation in your home and also help raise the value of your home if you decide to sell.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
- Save money on energy bills: After you upgrade to energy-efficient windows, you can expect a reduction in your bills by about 12% because you'll use less energy to heat or cool your house.
Estimated Cost of Window Replacement in Charlestown
Each window replacement company offers various services and has varying costs based on a few factors.
How Much Do New Windows Cost?
According to our research, the national average cost to install a single window is about $600. However, window installation costs can range from $200 to $1,200 a window. How much it will cost you is based on several factors, like size, number of windows, material, the location of your home, type and more.
It's also worth bearing in mind that energy-efficient windows will typically cost more initially, but Energy Star predicts that upgrading the windows on your Charlestown home translates to an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. The amount of money you'll save by switching to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
Costs will also vary based on the material you want for your window frames. Aluminum frames are the least expensive. They're sturdy, light and maintenance-free, but offer poor insulation. Vinyl frames are a bit more expensive and offer good insulation. Composite frames made with wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They're also aesthetically pleasing and offer decent insulation for your home.
What Services do Window Installers Offer?
The first question to ask yourself when getting new windows is: Do you need a full-frame installation or a pocket installation?
Full-frame installations involve replacing the full window — the sill, frame, trim and all. These are typically done when you want a different style for your windows or when it has a great amount of deterioration. Full-frame installations involve more time and labor and will increase overall costs. Pocket installations (or retrofits) involve replacing a window within the existing frame, which makes pocket installations take less time and therefore cost less. However, if the frame has any rot or deterioration, you will most likely need a full-frame installation instead.
Your window installation company can recommend the best type for your project. In Charlestown, the choice will mostly be based on the efficiency of your home and the age and condition of your existing frames.

How We Choose the Best Window Installers in Charlestown
In our hunt to make your home improvements easier and more eco-friendly in Charlestown, EcoWatch landed on the above companies as the best window installation companies in the city. Along with energy efficiency, we analyzed window companies all across the state and ranked them based on the following methodology:
Service Area
Since this is a guide for Charlestown, we gave more points to companies that cover the city. There are other reputable providers that didn't make our list because of the low odds that they would serve the average homeowner in Charlestown.
Work Quality
When installing new windows, the quality and range of services often plays just as important of a role in overall efficiency and performance as the type of window you get. 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
Customer feedback is another very important review factor. If the majority of customers don't have nice feedback about their experience with a certain company, it won't be featured on EcoWatch.
Cost
This one is a give-and-take: similar to other services, cheap window installation companies may not provide the most quality service. On the other hand, we want to make sure we're highlighting companies that offer a wide range of price and financing options so they're accessible to most homeowners.
Warranty
As discussed, windows are a serious investment, so you'll want to make sure that investment is protected. Window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have been in the industry for a while. Window installation companies that have more experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
Charlestown, PA Window Replacement FAQs
What is the typical cost to install new windows?
The average cost to replace a single window ranges between $450 and $650. There are several factors that influence the cost, including local labor costs, your property's location, the number of windows, the materials used in designing the windows, how energy-efficient the windows are and styles and sizes of windows.
Which type of window is the best?
A window's energy efficiency depends on a variety of factors, such as the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are typically the most energy-efficient since they are certified by the U.S. Department of Energy.
Can you replace your own windows?
If you're handy and have the time and patience to do the job right, it's possible to install your own windows. But if you don't have the time or experience, we don't recommend it.
When is it time to replace your windows?
Windows have a typical 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 damage anywhere on them, or they have become difficult to open or close, they may be in need of replacement.
Should I replace my windows all at once?
If you're upgrading your windows because of energy-efficiency, replacing all your windows at the same time is the only way to see a noticeable difference. On the other hand, if you have just a few windows that are damaged or leaky, you can replace just those.
