How Installing Energy-Efficient Windows in Radnor Saves You Money

Upgrading to energy-efficient windows can help improve the comfort of your home and help you save on electricity bills. Here's more information on how switching out your windows could help you:

  • Better temperature control in your home: Residing in a very cold place like Radnor can often mean relying on your heater to keep your home cool. Energy-efficient windows can reduce how much heat is lost through your windows when heating your home.
  • Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes tend to have windows that are outdated, leaky or maybe even damaged in some way. Upgrading your windows could help increase the value of your home if you decide to sell.
  • Save on electricity bills: According to the Department of Energy, heat gained or lost through windows makes up around 25-30% of residential energy use. Switching to energy-efficient models can help decrease that amount, therefore saving you about 12% more on your bills.
  • Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.

Estimated Cost of Window Replacement in Radnor

Windows come in different purposes, styles and shapes, so costs and services will differ greatly depending on your project. Below, we go over the average cost and services that you'll find from window installers.

How Much Do New Windows Cost?

The average cost to install a single window is about $600 but can range from $200 to $1,200. But prices differ 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 installations, which will add extra costs to your project.

It's also worth bearing in mind that energy-efficient windows will cost more initially, but Energy Star estimates that upgrading the windows on your Radnor home translates to an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. How much you'll save by upgrading to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.

Getting free quotes from several installers is the best way to figure out which one will work best for your budget.

What Services do Window Installers Offer?

There are typically two types of window replacement services: full-frame and pocket installations.

A full-frame installation replaces the total window, including the sill, frame, trim and the window panes. Because this kind of installation requires more time, it will be more expensive than a pocket installation. Pocket installations (also known as retrofits) are when you replace a window without replacing the frame. Pocket installations are on the simpler end and won't cost as much, but you can't do this kind of installment if you have any pre-existing rot or water damage.

Your window replacement company should be able to help you decide what's best for your needs. In Radnor, the decision will mostly be based on how old your windows are and if there's any damage. Wood can decay if not properly maintained over the years, so it's a good idea to have a professional check your frames and window sills.

How We Choose the Best Window Installers in Radnor

In our search to find the most reliable, eco-friendly window installers in Radnor, the EcoWatch team examined many companies before landing on these. Along with energy efficiency, we reviewed window companies all across the state and assigned rankings using the following methodology:

Service Area

This one is self-explanatory, but we've chosen to highlight window installers that serve the Radnor area so you can find the best window installation company near you.

Work Quality

We're willing to bet that you're not looking for a company to do a shoddy job installing windows. We've vetted each installer included on this list to ensure its technicians are well-qualified and that the company has received plenty of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed patterns in recent customer feedback to determine 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 most other categories, including professionalism, warranty, quality of parts, cost, quality of installation and more.

Cost

This one is a give-and-take: as with most services, cheap window installers are not going to provide the highest quality service. Still, 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. That's why 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 a good 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.

Radnor, IL Window Replacement FAQs

What is the average cost to install new windows in a home?

The national average cost to install one window is around $600 but can range from $200 to $1,200, depending on a variety of 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, bear in mind that energy-efficient windows may cost more upfront but can save you a decent amount of money 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 do not open will be more efficient than windows that do. If you want to be sure you'll get the most energy-efficient windows, look for models that have the blue Energy Star certification attached to them — they're certified energy-efficient by the U.S. Department of Energy.

What do window installation companies do?

Window installers will do 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.

When is it time to replace your windows?

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