How Installing Energy-Efficient Windows in Johnstown Saves You Money

By upgrading to energy-efficient windows, you can benefit in several ways, such as:

  • Protect your valuables from fading: When you switch to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will be protected from fading because of their ability to filter out damaging UV rays.
  • Save money on energy bills: According to the Department of Energy, heat gained or lost through windows accounts for about 25-30% of residential energy use. Switching to energy-efficient models can help decrease how much you have to pay, therefore saving you about 12% more on your bills.
  • Reduce your carbon footprint: You can reduce your carbon footprint by about 12% once you install Energy Star certified windows. In Johnstown, that's about 460 pounds per year on average.
  • Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes usually have windows that are outdated, drafty or potentially even damaged in some way.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 considering window installation, each company offers different services and costs. Let's go over some average costs and services.

How Much Do New Windows Cost?

The average cost to install a single window is about $600 but can range anywhere from $200 to $1,200. These estimates are based on the specifics of your installation, such as size, material, the location of your home, number of windows, type and more.

Whether or not you opt for energy-efficient windows is another factor that will affect the cost. These will typically cost more than other windows, but on the other hand, you can save about $438 a year on your energy bills in Johnstown.

Asking for free quotes from several providers is the best way to figure out which one is right for you.

What Services do Window Installers Offer?

In general, there are two types of window replacement services you can get: full-frame and pocket installations.

Full-frame installations are necessary when you want to change the style of your windows or your window has significant deterioration. With this service, your installers will replace the complete window, including the trim, sill and frame. Pocket installations (or retrofits) entail installing a new window within its existing frame, which makes pocket installations less labor-intensive and costly. However, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.

If you're still debating which kind of installation you should get, you can ask your installer and get their recommendation. The decision mostly is influenced by the age of your window frames and if there's any damage present.

How We Choose the Best Window Installers in Johnstown

The EcoWatch Reviews team is different from other reviewers because we examine these companies through a sustainability lens. We have assessed the top window installers in Johnstown primarily based on their energy efficient offerings, as it's what's best for the environment and for you as a homeowner. Energy-efficient windows can cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

Because this is a guide for Johnstown, we paid more attention to companies that cover the city. There are certainly other reputable providers that didn't make our list because of the low odds that they would serve the average homeowner in Johnstown.

Work Quality

When selecting new windows, the quality and breadth of services often plays just as important of a role in insulation and performance as the brand you opt for. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

We analyzed patterns in recent online reviews to find the companies with the most consistent customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it indicates the quality of services across nearly every category, including quality of parts, warranty, professionalism, quality of installation, cost and more.

Cost

Cheaper windows don't necessarily mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing the prices of providers, we awarded higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

As discussed previously, windows are a considerable investment, so you'll want to be certain that investment is protected. Window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) 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 installers that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.

Johnstown, CO Window Replacement FAQs

How much does a window install cost?

The national average cost to replace one window is around $600 but can range between $200 and $1,200, based on a variety of factors. The price is typically dependent on the size of the window, the location of your property and the type and material of the window. Also, bear in mind that energy-efficient windows may cost more initially 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 depends on a variety of factors, including the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are usually the most energy-efficient and are certified by the U.S. Department of Energy.

Can you install your own windows?

If you're handy and have experience with installing a replacement window, it's possible to install your own windows. But if you don't have the time or experience, we don't recommend trying it.

How long does it take to install windows?

Each window takes around 30 minutes to install depending on the kind of window. However, the window installation can take two days or more if you have a lot of windows that have to be installed.

Should I replace my windows all at the same time?

If your windows are greater than 20 years old, it's most likely time to replace all of them. At that point, they are usually less efficient, leakier and/or more damaged than new windows. Replacing your windows all at once will involve less paperwork and less stress.
