How Installing Energy-Efficient Windows in Charlestown Saves You Money
By upgrading to energy-efficient windows, you can take advantage of several benefits, including:
- More efficient energy usage in your home: Because the summers can get quite hot in Charlestown, homeowners often rely on their air conditioner a lot. Energy-efficient windows lower how much cool air is lost through your windows, which makes it easier to keep your house cool.
- More efficient energy usage in your household: In Charlestown where the winters can be very cold, energy-efficient windows decrease how much heat is lost through your windows, which makes it easier to keep your home warm.
- Reduce your carbon footprint: You can reduce your carbon footprint by about 12% after you install Energy Star certified windows. In Charlestown, that's about 286 pounds per year on average.
- Protect your investment: When you have an older home, your windows could also be outdated or damaged. Upgrading your windows is an important part of maintaining your property and its value.
Estimated Cost of Window Replacement in Charlestown
Windows come in varying shapes and sizes, so costs and services will vary considerably. Here are the average costs and the primary services that you can find from window installers.
How Much Do New Windows Cost?
Generally, Charlestown homeowners can expect their replacement window installations to range from $250 to $1,200. The average cost is at approximately $600. But prices vary considerably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also provide door installations and replacements, which will add extra costs to your project.
Whether or not you choose energy-efficient windows is another factor that will determine the cost. These will usually cost more than other windows, but on the other hand, you can save about $304 a year on your energy bills in Charlestown.
How much your window installation costs will also vary based on the kind of window material you choose for the frames. Wood windows are usually the most expensive, although it depends if they are completely wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are shown to be more efficient.
What Services do Window Installers Offer?
The first step when considering an installation is to decide whether you need a full-frame or pocket installation.
A full-frame installation replaces the total window, such as the windowsill, frame, trim and the window panes. Because this kind of installation is more involved, it will be more expensive than a pocket installation. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are on the simpler end and won't carry as large a bill, but you can't do this kind of installment if you have any pre-existing rot or water damage.
If you're unsure which window installation service you need, your installer can help you out. In general, the choice is based on factors like the age and condition of the home, the type of building material, budget and time restrictions.

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 chose the above companies as the top window installation companies in the city. We've evaluated the top window installers in Charlestown mainly based on energy efficiency, as it's the most sustainable option and the best one for homeowners. Energy-efficient windows have been shown to lower electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installers that serve the Charlestown area so you can find a quality 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 company in our guide to ensure its technicians are well-qualified and that the company has received tons of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent customer feedback to determine the companies with the most consistent customer satisfaction. Customer satisfaction might be the most important factor, as it reflects the quality of services across most other categories, including quality of installation, professionalism, cost, quality of parts, warranty and more.
Cost
This one is a give-and-take: similar to most services, cheap window companies may not provide the highest quality service. On the other hand, we want to make sure we're highlighting companies that provide a variety of price and financing options so they're accessible to most homeowners.
Warranty
Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to Charlestown's climate, homeowners will want to mitigate water damage, rot and low efficiency. We factored in local experience to reflect the ability of Charlestown window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Charlestown, PA Window Replacement FAQs
What is the typical cost to install windows?
The national average cost of replacing one window is about $600 but can range between $200 and $1,200, depending on a variety of factors. The price is typically 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.
What are the different types of windows?
The most common types of windows for homes include: transom windows, awning windows, picture windows, slider windows, casement windows, bay windows and double-hung and single-hung windows.
When do I have to use a window installation company?
Unless you have experience with home improvement projects and have the tools needed 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 some money by doing it yourself, hiring a company is a faster, more efficient and safer alternative.
When is it time to replace your windows?
Windows generally last around 20 to 30 years, but anytime you see damage on your windows, it's a good time to have them checked by an expert to see if they are in need of a repair or replacement.
