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.

A guide on the top window replacement companies in South Middleton may not seem like the most compelling article on EcoWatch, but trust us, windows have a more direct impact on your life than you might think. Potential leaks or drafts can lower your home’s energy efficiency by up to 30%, according to the Department of Energy. In South Middleton, that’s around $310 a year that you could save on your power bills after making the switch.

That’s also bad for the environment, as the extra energy used by damaged windows increases your carbon footprint.

Unlike other sites, EcoWatch ranks window companies on energy efficiency while also taking into consideration cost, customer satisfaction and service area.

    South Middleton Window Cost Calculator

    Calculate how much you can expect to pay for window installation and replacement in South Middleton, PA using our customized window cost calculator.

    Estimated Window Cost:
    161 homeowners have requested a free estimate in the last 3 days.

    Estimates will vary based on window dimensions and other unique factors to your home. Getting in touch with a local window installer is the best way to get an accurate cost estimate for your home.

    How Installing Energy-Efficient Windows in South Middleton Saves You Money

    There are quite a few perks of switching to energy-efficient windows. A few reasons you may want to consider making the switch are the following:

    • Protect your investment: When your home is on the older side, your windows could also be outdated or leaky. Keeping your windows up to date is an important part of maintaining your property and its real estate value.
    • Reduce your carbon footprint: Decreasing how much energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 286 pounds.
    • Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
    • Save money on electricity bills: Once you switch to energy-efficient windows, you can expect a reduction in your bills by about 12% because you’ll use less energy to heat or cool your home.

    Estimated Cost of Window Replacement in South Middleton

    Windows come in various purposes, styles and shapes, so costs and services will differ greatly depending on several factors. Below, we describe the typical cost and services that you can get from window replacement companies.

    How Much Do New Windows Cost?

    On average, South Middleton homeowners can anticipate their window replacements to range from $250 to $1,200. The most common installations sit at around $600. These figures are based on the specifics of your installation, like the location of your home, material, size, number of windows, type and more.

    Bear in mind that energy-efficient windows may cost more, but Energy Star estimates the upgrade will save you between $101 and $583 per year when you install single-pane windows and between $27 and $197 per year when you install double-pane, clear glass windows. Your savings will vary depending on your local climate, energy rates and individual home characteristics.

    We advise requesting free quotes from multiple window companies to find the right windows and the company that works best for your budget.

    What Services do Window Installers Offer?

    The first question to ask yourself when getting new windows is: Do you need a full-frame installation or a pocket installation?

    Full-frame installations involve replacing the whole window — the sill, frame, trim and all. These are typically done when you want a new style for your windows or when it has a great amount of deterioration. Full-frame installations are more involved and will increase overall costs. A pocket installation involves replacing a window without replacing the frame. This means instead of removing the whole window and reinstalling it, the window installer will just slide the replacement window (also called a retrofit or insert window) into the frame.

    If you’re still trying to decide which kind of installation you need, you can ask your installer and get their recommendation. The choice mostly is influenced by the age of your window frames and if there’s any damage.

    How We Choose the Best Window Installers in South Middleton

    EcoWatch differs from other reviewers because we’re examining these companies through a sustainability lens. Along with energy efficiency, we assessed window companies all across the state and assigned rankings based on the following methodology:

    Service Area

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

    Work Quality

    When picking new windows, the quality and variety of services can often play just as important of a role in insulation and performance as the type of window you get. We do rate window installers higher if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

    Customer Reviews

    Customer feedback is another super important review factor. If the majority of customers don’t have good things to say about their experience with a certain company, you won’t see it featured on EcoWatch.

    Cost

    Cheaper windows don’t necessarily mean better windows, but we know many of our readers try to keep costs as low as possible. When analyzing providers’ prices, we gave higher points 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

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

    South Middleton, PA Window Replacement FAQs

    How much should window installation cost?

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

    What are the different types of windows?

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

    Do I really need to use a window installation company?

    You should use a window installation professional whenever you want new windows. Installing windows is a involved process that can be difficult to do on your own, so it’s best handled by the professionals.

    Should I replace my windows all at the same time?

    If your windows are greater than 20 years old, it’s probably time to replace all of them. By that point, they are often less efficient, leakier and/or more damaged than new windows. Replacing your windows all at once will involve less paperwork and less stress.

    How long does window installation take?

    Because a window takes about 30 minutes to install, about 16 windows can be installed in an 8-hour work day.
