How Installing Energy-Efficient Windows in Marion Saves You Money

Upgrading to energy-efficient windows can improve the comfort of your home and help you save on energy bills. Here are more ways switching out your windows could help you:

  • Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
  • Better temperature control in your home: Living in a very cold place like Marion often means relying on your heater to keep your house cool. Energy-efficient windows can reduce how hard your heating system needs to work to heat your home.
  • Protect your investment: When you have an older home, your windows could also be outdated or leaky. Upgrading and repairing your windows is an important part of maintaining your property and its real estate value.
  • Save money on electricity bills: Since energy-efficient windows decrease the amount of energy used to heat or cool your home, they can help you save around $381 annually on your energy bills in Marion.

Estimated Cost of Window Replacement in Marion

When considering window installation, each company provides varying services and prices. Let's look at some typical costs and services.

How Much Do New Windows Cost?

The typical cost to install a single window is about $600 but can range anywhere from $200 to $1,200. This is because of the fact that the cost of window installations depend on several factors specific to your home, such as the size, material and number of windows you need to install, as well as the location of your property.

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 $381 a year on your energy bills in Marion.

The cost of your window installation will also vary based on the kind of window material you choose for the frames. Wood windows are usually the most expensive, though it depends if they are solid 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?

When it comes to window replacements, in general there are two kinds that your installer will have: full-frame and pocket installations.

A full-frame installation is a total window replacement. This service involves taking out the old window, the windowsill, and the exterior and interior trim. It also involves extra materials, including insulation and drip edges, which raise the total cost of the project. Also worth noting: you may have to touch up the paint around the window after a full-frame installation. Pocket installations are simpler and won't cost as much because they entail merely replacing the window within its existing frame. But if the frame has any damage or rot, you should opt for a full-frame installation instead.

If you're still trying to decide which type of installation to get, you can consult with your installer and get their recommendation. The choice mostly depends on how old the frames are and if there's any damage.

How We Choose the Best Window Installers in Marion

In our search to make your home improvements easier and more eco-friendly in Marion, the EcoWatch Reviews team chose the above companies as the best window installation companies in the city. We have reviewed the top window installation companies in Marion mostly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows can lower energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

Since this is a guide for Marion, we only included companies that cover the city. There are other reputable providers that didn't make the list because of the low odds that they would serve the average homeowner in Marion.

Work Quality

We're certain that you're not looking for a company to do a shoddy job installing windows. We've vetted each company featured on this list to make sure its contractors are well-qualified and that the company has gotten lots of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed trends in recent customer feedback to find the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction might be the most important factor, as it indicates the quality of services across most other categories, including quality of installation, professionalism, quality of parts, warranty, cost and more.

Cost

Cheaper windows don't necessarily mean better windows, but we know many of our readers want 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

Protecting your investment in new windows is important. 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 installers that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.

Marion, IN Window Replacement FAQs

What is the average cost to replace windows?

The national average cost to install a single window is around $600 but can range from $200 to $1,200, depending on a few different factors. The price is generally influenced by the size of the window, the location of your property and the type and material of the window. Also, remember that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.

What type of window is the most energy-efficient?

Generally, double-pane windows are more efficient than single-pane windows and windows that don't open will be more efficient than windows that do. To be sure you'll have the most energy-efficient windows, look for models that have the blue Energy Star certification attached to them — this means they're certified energy-efficient by the U.S. Department of Energy.

What do window installers do?

Window installation companies cover the entire process — from replacing old windows with brand new ones to cleaning up afterward. In addition, many companies offer window manufacturing, customization and repairs.

How often should you replace your windows?

Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, they probably need to be replaced. Other than that, if your windows have damage anywhere on them, or they have become difficult to operate, they may be in need of replacement.
