    How Installing Energy-Efficient Windows in Susquehanna Saves You Money

    When you switch to energy-efficient windows, you may see a few perks, including:

    • Save on electricity bills: After you switch to energy-efficient windows, you can see a reduction in your bills by about 12% because you’ll need less energy to heat or cool your house.
    • Protect your investment: If you have a relatively old home, your windows are most likely in need of replacement. Updating your windows can make your home more comfortable and also help increase the value of your house if you decide to sell.
    • Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% when you install Energy Star certified windows. In Susquehanna, that’s about 286 pounds per year on average.
    • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, reducing fading of your furniture, carpet and other valuables.

    Estimated Cost of Window Replacement in Susquehanna

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

    How Much Do New Windows Cost?

    Typically, homeowners in Susquehanna can anticipate that most window installations will range from $250 to $1,200, with the average cost at around $600. But costs will differ significantly depending on the current condition of your home, the quality of your products, the number of windows you need and your location. A lot of window companies also offer door installations and other add-ons like shutters, baths, coating and more. Additional services will increase overall project costs.

    Keep in mind that energy-efficient windows may have a higher price, but Energy Star estimates the upgrade will save you between $101 and $583 per year when installing single-pane windows and between $27 and $197 per year when you replace double-pane, clear glass windows. These savings vary based on your local climate, energy rates and individual home characteristics.

    Something else that affects the total cost is the material of the frame you select. Aluminum frames are typically the least pricey and are sturdy and relatively maintenance-free, but they offer poor insulation. On the other hand, wood frames are the most expensive, as they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.

    What Services do Window Installers Offer?

    The first step of a window installation is to figure out whether you need a full-frame or pocket installation.

    Full-frame installations involve replacing the whole window — the sill, frame, trim and all. These are most common when you want a new style for your windows or when it has significant damage. Full-frame installations involve more time and labor and will increase overall costs. Pocket installations are on the simpler end and won’t carry as large a bill because they involve merely replacing the window within its existing frame. But if the frame has any damage or deterioration, you should opt for a full-frame installation instead.

    If you’re unsure which window installation service you should get, your installer should be able to assist you. In general, the decision is influenced by factors like the age and condition of the home, the type of building material, budget and time restrictions.

    How We Choose the Best Window Installers in Susquehanna

    EcoWatch reviews are different from other reviews, as we’re examining these companies through a sustainability lens. We have decided to assess the best window replacement companies in Susquehanna primarily based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows can cut your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

    Service Area

    Since this is a guide for Susquehanna, we gave more points to companies that cover the city. There are certainly other reputable providers that didn’t make the list because they wouldn’t be able to serve homeowners in Susquehanna.

    Work Quality

    We’re willing to bet that you’re looking for professionals who do a great job installing windows. We’ve vetted each company included in our guide to make sure its contractors are well-qualified and that the company has received tons of positive customer feedback to vouch for its service.

    Customer Reviews

    Customer feedback is another super important review factor. If most customers don’t have good feedback about their service from a certain window installation company, it won’t be featured on EcoWatch.

    Cost

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

    Warranty

    As discussed, windows are a significant investment, so you’ll want to be certain that investment is protected. Window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

    Years of Experience

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

    Susquehanna, PA Window Replacement FAQs

    How much should a window install cost?

    The national average cost of replacing a single window is about $600 but can range from $200 to $1,200, depending on a variety of factors. The price is typically dependent on the type and material of the window, the location of your property and the size of the window. Also, keep in mind that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.

    What are the different kinds of windows?

    There are various kinds of windows you can get for your house, such as slider windows, double-hung and single-hung windows, transom windows, awning windows, bay windows, casement windows and picture windows.

    Can you replace your 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 experience, we recommend getting a professional to do it for you.

    What time of year is the best time to replace my windows?

    Replacement windows can be installed at any time, but warmer weather is typically better. No matter when you install them, the contractors will take steps to ensure that too much hot or cold air doesn’t get into the home, so the temperature outside doesn’t necessarily matter that much. Most importantly, the weather should be dry.

    Should I replace all my windows at once?

    If you want to get more efficient windows and save money on energy costs, replacing all of your windows at the same time is the only way to see a noticeable difference. However, if you have just a few windows that are damaged or leaky, you can replace just those.
