How Installing Energy-Efficient Windows in Johnstown Saves You Money

Energy-efficient windows can benefit you in more than one way. Here are some reasons you may want to think about making the switch:

• Protect your valuables from fading: When you upgrade to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will be protected from fading due to their ability to filter out harmful UV rays.
• Decrease your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% once you install Energy Star certified windows. In Johnstown, that’s about 460 pounds per year on average.
• Save money on energy bills: Switching to energy-efficient windows reduces your energy bills by about 12% since you use less energy.
• Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its real estate value, particularly if your home is on the older side.

Estimated Cost of Window Replacement in Johnstown

Each window installer offers various services and has different price points depending on a few factors.

How Much Do New Windows Cost?

According to our research, the typical cost of replacing a single window is about $600. However, window replacement costs can range from $200 to $1,200 a window. This is because of the fact that the cost of window installations depend on several factors specific to your home, including the size, material and number of windows you need to install, as well as where your property is located.

Bear in mind that energy-efficient windows may cost more, but Energy Star predicts the upgrade will save you between $101 and $583 a year when you replace single-pane windows and between $27 and $197 per year when you replace double-pane, clear glass windows. Your savings will vary based on your local climate, energy rates and individual home characteristics.

We recommend getting free quotes from several window installers to find the right windows and the company that works best for you.

What Services do Window Installers Offer?

The first step when considering a replacement is to think about whether you should get a full-frame or pocket installation.

A full-frame installation replaces the entire window, including the windowsill, frame, trim and the window panes. Because this kind of installation requires more time and labor, it will cost more than a pocket installation. A pocket installation entails installing a new window without replacing the frame. So, instead of taking out the whole window and reinstalling it, the window installer will just slide the replacement window (also called a retrofit or insert window) into the frame.

Your window replacement company should 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 damage. Wood can decay if it’s not properly maintained 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

EcoWatch reviews differ from most reviews, as we evaluate these companies through a sustainability lens. Along with energy efficiency, we analyzed each installer and ranked them using the following methodology:

Service Area

Because this is a guide for Johnstown, we gave more points to companies that provide services to the city. There are certainly reputable providers that didn’t make the list because they wouldn’t be able to serve homeowners in Johnstown.

Work Quality

We’re certain that you’re looking for a company to do a great job installing windows. We’ve vetted each installer included in our guide to ensure its technicians are well-qualified and that the company has gotten a lot of positive customer feedback to vouch for its service.

Customer Reviews

Customer feedback is another super important review factor. If the majority of customers don’t have positive feedback about their service from a certain installer, you won’t see it featured on EcoWatch.

Cost

This one is a give-and-take: as with other services, cheap window installers won’t always provide the highest quality service. On the other hand, we want to make sure 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 give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Lastly, we like to see companies that have a proven track record in the industry. Window installation companies that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.
