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.

Although green energy sources like wind and solar are important when it comes to decreasing your carbon footprint, improving your home’s energy efficiency can also have a considerable impact on home energy conservation. When it’s the middle of winter, your old and leaky windows could be making your home more difficult to heat and more uncomfortable for you.

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

Efficient windows are of particular importance in Park Forest Village, where the temperature varies throughout the year. According to Energy Star, switching to energy-efficient windows can save the average homeowner up to $325 each year.

    How Installing Energy-Efficient Windows in Park Forest Village Saves You Money

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

    • Reduce your carbon footprint: Because energy-efficient windows improve the insulation in your house, you can reduce your indirect greenhouse gas emissions by about 12%, according to Energy Star.
    • 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.
    • Protect your investment: Upgrading your windows is an important part of maintaining your property and its real estate value, especially if you have an older home.
    • Save money on energy bills: Since energy-efficient windows lower how much energy you need to heat or cool your home, they can help you save about $325 annually on your energy bills in Park Forest Village.

    Estimated Cost of Window Replacement in Park Forest Village

    Each window replacement company offers varying services and has different costs based on several factors.

    How Much Do New Windows Cost?

    Though the typical cost to replace a single window is about $600, it can range from $200 to $1,200. This is due to the fact that the cost of window installations depend on several factors specific to your home, including the size, material and number of windows you need to replace, as well as where your property is located.

    Whether or not you want to install 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 $325 a year on your energy bills in Park Forest Village.

    Costs will also vary depending on the material you pick for your window frames. Aluminum frames are the least expensive. They’re sturdy, light and easy to maintain, but offer poor insulation. Vinyl frames are a bit more expensive and provide good insulation. Composite frames made from wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They’re also aesthetically pleasing and offer decent insulation for your home.

    What Services do Window Installers Offer?

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

    Full-frame installations involve replacing the full window, including the trim, frame and sill. Full-frame installations are necessary when you want to change the style of your windows or your window has significant damage. Because these installations are more involved, they will increase the overall cost. Pocket installations are simpler and won’t cost as much, as they entail merely replacing the window within its existing frame. But if the frame has any damage or rot, you may have to get a full-frame installation instead.

    If you’re still debating which type of installation you need, you can consult with your installer and get their advice. The choice mostly depends on how old the frames are and if there’s any damage.

    How We Choose the Best Window Installers in Park Forest Village

    In our hunt to make your home improvements easier and more eco-friendly in Park Forest Village, EcoWatch assessed dozens of companies before landing on these. Along with energy efficiency, we assessed several window installers in Park Forest Village and assigned rankings based on the following methodology:

    Service Area

    Since this is a guide for Park Forest Village, we gave more points to companies that provide services to the city. There are other reputable providers that didn’t make our list because of the low odds that they would serve the average homeowner in Park Forest Village.

    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 on this list to make sure its technicians are well-qualified and that the company has received lots of positive customer feedback to vouch for its service.

    Customer Reviews

    We analyzed patterns in recent online reviews to determine the companies with the most consistent customer satisfaction. Customer satisfaction may be the most important factor, as it indicates the quality of services across most other categories, including cost, quality of parts, warranty, quality of installation, professionalism and more.

    Cost

    Cheaper windows don’t necessarily mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing providers’ prices, we gave higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.

    Warranty

    As discussed previously, windows are a significant 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

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

    Park Forest Village, PA Window Replacement FAQs

    What is the typical cost to replace windows in a home?

    The average cost to install a single window can range from $450 to $650. There are a variety of factors that influence how much it costs, which include your property’s location, the materials used in designing the windows, local labor costs, styles and sizes of windows, how energy-efficient the windows are and the number of windows.

    Which kind of window should I get?

    Generally, double-pane windows will be more efficient than single-pane windows and windows that do not open are more efficient than windows that do. If you want to be sure you’re getting the most energy-efficient windows, look for models that have the blue Energy Star certification — that means they’re certified energy-efficient by the U.S. Department of Energy.

    Can you replace your own windows?

    If you’re handy and know how to replace a window, it’s possible to install your own windows. But if you don’t have the time or skills, we recommend getting a professional to do it for you.

    Should I replace all my windows at once?

    If your windows are greater than 20 years old, it’s probably time to replace all of them. At that point, they are often less efficient, draftier and/or more damaged than new windows. Doing your windows all at the same time will involve less paperwork and less time.
