    How Installing Energy-Efficient Windows in Brentwood Saves You Money

    Energy-efficient windows can provide benefits in several ways. Here are a few reasons you may want to make the switch:

    • Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its value, particularly if you have an older home.
    • Reduce your carbon footprint: In Brentwood, you can cut your indirect greenhouse gas emissions by about 307 pounds per year once you install energy-efficient windows.
    • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only insulate your home better, but also filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
    • Save on energy bills: Since energy-efficient windows decrease the amount of energy used to heat or cool your home, the switch can help you save about $215 annually on your energy bills in Brentwood.

    Estimated Cost of Window Replacement in Brentwood

    Windows come in varying shapes, purposes and styles, so costs and services will vary greatly depending on your project. Below, we describe the average cost and services that you’ll find from window installers.

    How Much Do New Windows Cost?

    Though the national average cost of installing a single window is about $600, it can range from $200 to $1,200. These numbers are based on specific characteristics of your installation, like number of windows, the location of your home, material, type, size and more.

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

    Something else that affects the overall cost is the material you pick for your frame. Aluminum frames are typically the least expensive and are sturdy and light, but they offer 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 as well and cost somewhere between the other two.

    What Services do Window Installers Offer?

    Generally, there are two types of window installation services companies offer: full-frame and pocket installations.

    Full-frame installations entail replacing the complete window, including the sill, frame and trim. You most likely need a full-frame installation when you want to change the style of your windows or your window has noticeable rot or deterioration. Because these installations are more involved, they will raise the total cost. A pocket installation entails replacing a window within the existing frame. This means instead of tearing out the whole unit and rebuilding it, the installer will just put the replacement window (also called a retrofit or insert window) into the frame.

    If you’re not sure which kind of window installation service you should get, your installer can assist you. Typically, the choice 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 Brentwood

    EcoWatch reviews are different from other reviews, as we’re examining these companies through a sustainability lens. Along with energy efficiency, we assessed window companies all across the state and ranked them based on the following methodology:

    Service Area

    Because this is a guide for Brentwood, we paid more attention to companies that serve the city. There are other reputable providers that didn’t make the cut because of the low odds that they would serve the average homeowner in Brentwood.

    Work Quality

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

    Customer Reviews

    We analyzed patterns in recent online reviews to find the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across most other categories, including quality of parts, quality of installation, cost, professionalism, warranty and more.

    Cost

    This one is a give-and-take: as with other services, cheap window installation companies are not going to provide the most quality service. On the other hand, we want to ensure we’re highlighting companies that provide a variety of price and financing options so they’re accessible to most homeowners.

    Warranty

    Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.

    Years of Experience

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

    Brentwood, NY Window Replacement FAQs

    How much should window installation cost?

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

    Which type of window should I get?

    A window’s energy efficiency is affected by several factors, including the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are often the most energy-efficient since they are certified by the U.S. Department of Energy.

    What do window installers do?

    Window installation professionals cover the entire process — from replacing your old windows with brand-new ones to cleaning up after the windows have been put in place. Additionally, many companies offer window manufacturing, customization and repairs.

    When is the best time of year to replace windows?

    Although you can install windows any time of year, warmer weather is usually better for installing replacement windows. Additionally, it shouldn’t be raining, as rain can make the installation more difficult.
