How Installing Energy-Efficient Windows in Johnstown Saves You Money
There are quite a few benefits of switching to energy-efficient windows. A few reasons you may want to consider making the switch include the following:
- Decrease your carbon footprint: By using less energy once you switch to Energy Star certified windows, you'll also be reducing your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Save on power bills: Upgrading to energy-efficient windows reduces your energy bills by about 12% because you use less energy.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
- Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes tend to have windows that are outdated, drafty or potentially even damaged in some way. Upgrading your windows could help increase the value of your property if you decide to sell.
Estimated Cost of Window Replacement in Johnstown
When researching window installation, each company offers different services and costs. Let's look at some average costs and services.
How Much Do New Windows Cost?
According to our research, the typical cost to install a single window is about $600. However, window replacement costs can range from $200 to $1,200 per window. How much it will cost you varies based on several factors, such as size, the location of your home, material, type, number of windows and more.
Whether or not you want to install energy-efficient windows is another factor that will affect the cost. These will almost always cost more than other windows, but on the other hand, you can save about $319 a year on your energy bills in Johnstown.
Getting free quotes from several providers is the best way to figure out which one will work best for your budget.
What Services do Window Installers Offer?
There are generally two kinds of window installation services: full-frame and pocket installations.
Full-frame installations entail replacing the total window, including the trim, sill and frame. You most likely need a full-frame installation when you want a new style or your window has noticeable rot or deterioration. Because full-frame installations are more involved, they will raise the total cost. Pocket installations (or retrofits) involve replacing a window within its existing frame, which makes pocket installations more simple and affordable. However, if the frame has any damage or rot, you should opt for a full-frame installation instead.
Your window installation company will be able to help you decide what's best for your needs. In Johnstown, the decision will mostly be based on the age of your windows and if there's any moisture damage. Wood can decay if it's not maintained properly over the years, so it's good to have a professional examine your frames and window sills.

How We Choose the Best Window Installers in Johnstown
The EcoWatch Reviews team differs from most reviewers because we're examining these companies through a sustainability lens. Along with energy efficiency, we evaluated several window installers in Johnstown and ranked them using the following methodology:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installers that serve Johnstown so you can find the best window installation company near you.
Work Quality
When choosing new windows, the quality and variety of services can often play just as important of a role in insulation and performance as the brand you opt for. We do give window installers higher marks if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
We analyzed trends in recent customer feedback to find the companies with the highest rates of customer satisfaction. Customer satisfaction may be the most important factor, as it reflects the quality of services across most other categories, including professionalism, quality of parts, cost, quality of installation, warranty and more.
Cost
This one is a give-and-take: similar to most services, cheap window companies may not provide the most quality service. On the other hand, we want to ensure we're highlighting companies that offer a range 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 offer 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 installation companies that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Johnstown, PA Window Replacement FAQs
What is the typical cost to replace windows?
The national average cost to replace a single window is around $600 but can range between $200 and $1,200, depending on a few different factors. The price is typically influenced by 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 initially but can save you hundreds of dollars a year in energy bills.
Which type of window is the best?
Generally, double-pane windows will be 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 — they're certified energy-efficient by the U.S. Department of Energy.
What services do window installation companies offer?
Window installation professionals travel to your home to remove your old windows and replace them with new ones. Some companies install products manufactured by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation.
How often should you replace your windows?
Windows generally have a lifespan of 20 to 30 years, but anytime you notice damage on your windows, it's a good idea to have them checked by an expert to see if they are in need of a repair or replacement.
Should I replace my windows all at the same time?
If you're upgrading your windows to save on your energy bills, replacing all of the windows together is the only way to gain that benefit. However, if you have just one or two windows that are broken or leaky, you can replace just those.
