Why you can trust EcoWatch

Our panel of energy experts work tirelessly to create unbiased reviews and informative content to help homeowners make educated decisions. No other windows site has covered energy efficiency and sustainability as long as EcoWatch, which means we're going to help you find windows replacements that will save on your energy bill and put more money back in your wallet.

Whether you're updating for aesthetics or have windows that need repairs, windows play a vital role in conserving your home's electricity. Damaged or outdated windows can cost you in energy bills. In fact, the Department of Energy estimates that 25-30% of your house’s heat or cool air could be lost through your windows.

That’s also bad news for the environment because the extra energy used by outdated windows increases your carbon footprint.

So if you’re constructing a new home, renovating or replacing your windows in Radnor, this is the best place to get started.

    Estimated Window Cost:

    How Installing Energy-Efficient Windows in Radnor Saves You Money

    Energy-efficient windows can benefit you in more than one way. Here are a few reasons you may want to think about making the switch:

    • Decrease your carbon footprint: By using less energy after you upgrade to energy-efficient windows, you’ll also be lowering your carbon dioxide emissions by about 12%, according to Energy Star.
    • Protect your investment: If you have a relatively old home, your windows are most likely in need of replacement. Upgrading your windows can improve the insulation in your home and also help increase the value of your home if you decide to sell.
    • Save on electricity bills: Once you upgrade to energy-efficient windows, you can see a reduction in your bills by about 12% since you’ll use less energy to heat or cool your house.
    • Protect your valuables from fading: When you switch to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less due to their ability to filter out harmful UV rays.

    Estimated Cost of Window Replacement in Radnor

    Each window replacement company provides varying services and has varying price points depending on several factors.

    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. But costs will vary considerably depending on the current condition of your home, the number of windows you need, the quality of your products and your location. A lot of window companies also offer door installations and other add-ons like shutters, coating, baths and more. Additional services will increase overall project costs.

    It’s important to note that windows with higher efficiency may cost more upfront but can save you hundreds of dollars via returns on your energy bills. Investing in certified energy-efficient windows can save Radnor homeowners $316+ a year when replacing single-pane windows.

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

    What Services do Window Installers Offer?

    When considering window replacements, there are typically two kinds that your provider will offer: full-frame and pocket installations.

    A full-frame installation replaces the entire window, including the windowsill, frame, trim and the window panes. Because this kind of installation requires more time and labor, it will be more expensive than a pocket installation. A pocket installation means replacing a window without removing the entire frame, which is usually less expensive than a full-frame installation.

    Your window installation company should be able to help you decide which type of installation you need.

    How We Choose the Best Window Installers in Radnor

    EcoWatch is different from most reviewers because we evaluate these companies through a sustainability lens. We’ve evaluated the best window replacement companies in Radnor primarily based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows can reduce your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

    Service Area

    This one is pretty self-explanatory, but we’ve chosen to highlight window installers that serve a wide variety of states and cities so you can find the best window installation company near you.

    Work Quality

    When installing new windows, the quality and range of services can often play just as important of a role in overall efficiency and performance as the brand you get. We do give window installers higher marks if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

    Customer Reviews

    Another self-explanatory yet very important review factor is customer feedback. If the majority of customers don’t have positive things to say about their service from a certain company, it won’t be featured on EcoWatch.

    Cost

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

    Warranty

    As discussed, windows are a substantial investment, so you’ll want to be certain that investment is well protected. Window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.

    Years of Experience

    Lastly, we like to see companies that have a good track record in the industry. Window installation companies that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.

    Radnor, PA Window Replacement FAQs

    How much does window installation cost?

    The typical cost to install a window ranges between $450 and $650. There are many factors that affect the price, including local labor costs, the number of windows, the materials used in designing the windows, how energy-efficient the windows are, your property’s location and styles and sizes of windows.

    What are the kinds of windows?

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

    What services do window installation companies provide?

    Window installation professionals visit your property to remove your old windows and replace them with new ones. Some companies install products distributed by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation.

    How often do you need to replace windows?

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