    How Installing Energy-Efficient Windows in Hampton Bays Saves You Money

    Upgrading to energy-efficient windows can improve the comfort of your home and help you save on energy bills. Here are more ways upgrading your windows could benefit you:

    • Protect your valuables from fading: When you upgrade to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less due to their ability to filter out damaging UV rays.
    • Save on power bills: Once you install energy-efficient windows, you can expect a reduction in your bills by about 12% because you’ll require less energy to heat or cool your house.
    • Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its real estate value, especially if your home is on the older side.
    • Decrease your carbon footprint: You can reduce your carbon footprint by about 12% after you install Energy Star certified windows. In Hampton Bays, that’s about 307 pounds per year on average.

    Estimated Cost of Window Replacement in Hampton Bays

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

    How Much Do New Windows Cost?

    According to our research, the average cost to install a single window is about $600. However, window replacement costs can range from $200 to $1,200 per window. This is because of the fact that window installations are based on a variety of factors specific to your home, like the size, material and number of windows you need to install, as well as the location of your property.

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

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

    What Services do Window Installers Offer?

    When it comes to window replacements, there are typically two types that your provider will have: full-frame and pocket installations.

    Full-frame installations involve replacing the complete window, including the trim, frame and sill. You most likely need a full-frame installation when you want to change the style of your windows or your window has noticeable damage. Because these installations are more involved, they will increase overall costs. A pocket installation involves replacing a window without replacing the frame. So, instead of removing the whole unit and reinstalling it, the contractor will just slide the replacement window (also called a retrofit or insert window) into the frame.

    If you’re still debating which type of installation to get, you can ask your installer and get their recommendation. The choice mostly depends on the age of your window frames and if there’s any damage present.

    How We Choose the Best Window Installers in Hampton Bays

    EcoWatch reviews differ from most reviews, as we look at these companies through a sustainability lens. We’ve evaluated the best window replacement companies in Hampton Bays mainly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows have been shown to cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

    Service Area

    Since this is a guide for Hampton Bays, we paid more attention to companies that provide services to the city. There are certainly other reputable providers that didn’t make the cut because they wouldn’t be able to serve homeowners in Hampton Bays.

    Work Quality

    We’re certain that you’re looking for professionals who do a great job installing windows. We’ve vetted each company in our guide to ensure its contractors are well-qualified and that the company has gotten plenty of positive customer feedback to vouch for its service.

    Customer Reviews

    Another self-explanatory yet super important review factor is customer feedback. If most customers don’t have good feedback about their experience with a certain company, you won’t see it featured on EcoWatch.

    Cost

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

    Warranty

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

    Years of Experience

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

    Hampton Bays, NY Window Replacement FAQs

    How much should window installation cost?

    The national average cost of installing a single window is about $600 but can range between $200 and $1,200, based on a variety of factors. The price is typically influenced by the size of the window, the type and material of the window and the location of your property. Also, bear 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 home, such as awning windows, slider windows, bay windows, casement windows, picture windows, double-hung and single-hung windows and transom windows.

    What do window installers do?

    Window installers visit your property to remove your old windows and replace them with new ones. Some companies install products made by other companies, whereas others install their own windows. The installer will also clean up after the installation.

    When is the best time of year to replace windows?

    Replacement windows can be installed during any season, but autumn might be best. No matter when you install them, the contractors will take steps to make sure that too much hot or cold air doesn’t get into your house, so the temperature outside doesn’t necessarily matter that much. Most importantly, the weather should be dry.
