How Installing Energy-Efficient Windows in Johnstown Saves You Money

Energy-efficient windows can offer benefits in several ways. Here are some reasons you may want to take the plunge and make the switch:

  • Protect your investment: When you have an older home, your windows could also be outdated or leaky. Upgrading your windows is an important part of maintaining your property and its real estate value.
  • Save on power bills: Since energy-efficient windows reduce the amount of energy used to heat or cool your home, the switch can help you save about $319 annually on your energy bills in Johnstown.
  • Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
  • Reduce your carbon footprint: In Johnstown, you can lower your indirect greenhouse gas emissions by about 286 pounds per year once you install energy-efficient windows.

Estimated Cost of Window Replacement in Johnstown

When considering window installation, each company offers different services and prices. Let’s look at some average costs and services.

How Much Do New Windows Cost?

Although the average cost to install one window is around $600, it can range anywhere from $200 to $1,200. But costs vary remarkably 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 replacements, which have a higher price tag.

Whether or not you want to install energy-efficient windows is another factor that will affect the cost. These will usually cost more than other windows, but on the other hand, you can save about $319 a year on your energy bills in Johnstown.

The cost of your window installation will also vary depending on the type of material you choose for the frames. Wood windows are typically the most expensive, though it depends on whether they are 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are more efficient.

What Services do Window Installers Offer?

The first question to ask yourself when considering a window replacement is: Do you need a full-frame installation or a pocket installation?

A full-frame installation replaces the full window, such as the windowsill, frame, trim and the window panes. As this type of installation requires more time and labor, it will be more expensive than a pocket installation. Pocket installations (or retrofits) entail replacing a window within its existing frame, which makes pocket installations more simple and affordable. But, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.

If you’re not sure which kind of window installation service you should get, your installer should be able to help you out. Typically, the choice is influenced by factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Johnstown

The EcoWatch Reviews team differs from other reviewers because we evaluate these companies through a sustainability lens. We’ve reviewed the top window installers in Johnstown mostly based on their energy efficient offerings, as it’s the most sustainable option and the best one for homeowners. Energy Star certified windows have been shown to reduce your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

Since this is a guide for Johnstown, we gave more points to companies that provide services to the city. There are certainly other reputable providers that didn’t make the cut 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 company included on this list to make sure its technicians are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.

Customer Reviews

Customer feedback is another very important review factor. If most customers don’t have good feedback about their service from a certain company, you won’t see it featured on EcoWatch.

Cost

This one is a give-and-take: similar to other services, cheap window installers may not provide the highest quality service. Still, we want to ensure we’re highlighting companies that offer a wide range of price and financing options so they’re accessible to most homeowners.

Warranty

Protecting your investment in new windows is important. That’s why window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Because of Johnstown’s climate, homeowners need to be wary of low efficiency, rot and water damage. We factored in local experience to reflect the ability of Johnstown window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.

Johnstown, PA Window Replacement FAQs

What is the typical cost to install windows in a home?

The national average cost of replacing a single window is around $600 but can range from $200 to $1,200, based on a variety of factors. The price is usually influenced by the location of your property, the size of the window and the type and material of the window. Also, remember that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.

What kind of window is the best for energy efficiency?

A window’s energy efficiency is influenced by a number of factors, such as the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are usually the most energy-efficient since they are certified by the U.S. Department of Energy.

What services do window installation companies offer?

Window installers cover the entire process — from replacing your old windows with new ones to cleaning up after the windows have been put in place. In addition, a lot of companies offer window manufacturing, customization and repairs.

How often should you replace windows?

Windows have an average 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 the same time?

If you’re upgrading your windows to get more efficient windows, replacing all the windows at the same time is the only way to gain that benefit. On the other hand, if you have only one or two windows that are broken or drafty, you can replace just those.
