How Installing Energy-Efficient Windows in Radnor Saves You Money

Energy-efficient windows can offer benefits in several ways. Here are a few reasons you may want to consider making the switch:

  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
  • Protect your investment: When you have an older home, your windows could also be outdated or leaky.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 value.
  • Reduce your carbon footprint: Reducing how much energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by 286 pounds per year on average.
  • Save money on power bills: Installing energy-efficient windows lowers your energy bills by about 12% because you use less energy.

Estimated Cost of Window Replacement in Radnor

Windows come in different shapes and sizes, so costs and services will differ remarkably. Here are the typical costs and the primary services that you'll find from the average window installation company.

How Much Do New Windows Cost?

According to our research, the average cost of replacing a single window is around $600. However, window installation costs can range from $200 to $1,200 a window. But costs differ considerably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also provide door replacements, which carry a higher price tag.

Whether or not you choose energy-efficient windows is another factor that will influence the cost. These will usually cost more than other windows, but on the other hand, you can save about $311 a year on your energy bills in Radnor.

Another factor that influences the overall cost is the material of the frame you select. Aluminum frames are generally the least pricey and are sturdy and light, but they provide poor insulation. On the other hand, wood frames cost the most, as they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.

What Services do Window Installers Offer?

The first thing to ask yourself when planning a window installation is: Do you want a full-frame installation or a pocket installation?

A full-frame installation replaces the complete window, such as the windowsill, frame, trim and the window panes. As this kind of installation is more involved, it will cost more than a pocket installation. A pocket installation involves replacing a window within the old frame. So, instead of removing the whole unit and reinstalling it, the installer will just put the replacement window (also called a retrofit or insert window) into the frame.

If you're still debating which kind of installation to get, you can ask your provider and get their recommendation. The decision mostly depends on how old the frames are and if there's any damage present.

How We Choose the Best Window Installers in Radnor

EcoWatch differs from most reviewers because we look at these companies through a sustainability lens. Along with energy efficiency, we assessed each installer and assigned rankings based on 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 right window installation company near you.

Work Quality

We're certain that you're not looking for a company to do a shoddy job installing windows. We've vetted each installer in our guide to ensure its technicians are well-qualified and that the company has gotten tons of positive customer feedback to vouch for its service.

Customer Reviews

Another self-explanatory yet very important review factor is customer feedback. If the majority of customers don't have nice things to say about their service from a certain installer, 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 most quality service. On the other hand, we want to ensure we're highlighting companies that offer a spectrum of price and financing options so they're accessible to most homeowners.

Warranty

As discussed, windows are a hefty investment, so you'll want to make sure that investment is protected. Window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Due to Radnor's climate, homeowners will want to mitigate water damage, low efficiency and rot. We factored in local experience to reflect the ability of Radnor window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.

Radnor, PA Window Replacement FAQs

How much should window installation cost?

The national average cost to replace a window is about $600 but can range between $200 and $1,200, depending on a variety of factors. The price is often influenced by the type and material of the window, the location of your property and the size 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 are the most common kinds of replacement windows?

The most common kinds of windows for homes include: casement windows, slider windows, double-hung and single-hung windows, awning windows, picture windows, transom windows and bay windows.

Can I replace my own windows?

If you're handy and have the time and patience to do the job right, it's possible to install your own windows. However, if you don't have the time or skills, we recommend getting a professional to do it for you.

How often do you need to replace windows?

Windows generally last around 20 to 30 years, but anytime you notice damage on your windows, it's a good time to have them checked by an expert to see if they need any repairs or replacements.

Should I replace my windows all at once?

If you want to get more efficient windows and save money on your energy bills, replacing all the windows together is the only way to see a noticeable difference. On the other hand, if you have only a few windows that are broken or drafty, you can replace just those.
