    Beloit Window Cost Calculator

    Calculate how much you can expect to pay for window installation and replacement in Beloit, WI 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 Beloit Saves You Money

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

    • Protect your valuables from fading: When you upgrade to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will fade less because of their ability to filter out harmful UV rays.
    • Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% once you install Energy Star certified windows. In Beloit, that’s about 715 pounds per year on average.
    • Save money on electricity bills: Since energy-efficient windows reduce how much energy you need to heat or cool your home, they can help you save about $483 annually on your energy bills in Beloit.
    • Protect your investment: When you have an older home, your windows could also be outdated or drafty. Upgrading your windows is an important part of maintaining your property and its real estate value.

    Estimated Cost of Window Replacement in Beloit

    Windows come in different styles, shapes and purposes, so costs and services will vary tremendously depending on several factors. Below, we detail the typical cost and services that you can get from window installation companies.

    How Much Do New Windows Cost?

    Although the typical cost of replacing one window is about $600, it can range anywhere from $200 to $1,200. How much it will cost varies based on several factors, including number of windows, type, the location of your home, material, size and more.

    It’s also worth keeping in mind that energy-efficient windows will cost more initially, but Energy Star estimates that upgrading the windows on your Beloit home can mean an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. The amount of money you’ll save by upgrading to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.

    How much your window installation costs will also vary based on the kind of window material you choose for the frames. Wood windows are typically the most expensive, but it depends on whether they are completely wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are shown to be more efficient.

    What Services do Window Installers Offer?

    The first step of an installation is to think about whether you need a full-frame or pocket installation.

    A full-frame installation is a replacement of the full window. It involves taking out the old window, the windowsill, and the exterior and interior trim. It also involves extra materials, like insulation and drip edges, which raise the total cost of the project. It’s also worth noting that you may have to touch up the paint surrounding the window after a full-frame installation. A pocket installation means replacing a window without taking out the complete frame, which tends to be cheaper than a full-frame installation.

    If you’re still trying to decide which kind of installation you need, you can consult with your provider and get their recommendation. The decision mostly depends on how old the frames are and if there’s any damage.

    How We Choose the Best Window Installers in Beloit

    The EcoWatch Reviews team is different from other reviewers because we examine these companies through a sustainability lens. We’ve reviewed the best window installers in Beloit mostly based on their energy efficient offerings, as it’s what’s best for the environment and for you as a homeowner. Energy Star certified windows have been shown to lower 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 Beloit, we gave more points to companies that provide services to the city. There are certainly reputable providers that didn’t make the cut because of the low odds that they would serve the average homeowner in Beloit.

    Work Quality

    When it comes to new windows, the quality and variety of services can often play just as important of a role in insulation and performance as the brand of window you opt for. We do give window installers more points if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

    Customer Reviews

    Customer feedback is another very important review factor. If most customers don’t have nice feedback about their service from a certain installer, you won’t see it featured on EcoWatch.

    Cost

    This one is a give-and-take: as with other services, cheap window installers may not provide the highest quality service. Still, we want to ensure we’re highlighting companies that offer a range of price and financing options so they’re accessible to most homeowners.

    Warranty

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

    Years of Experience

    Lastly, we like to see companies that have been in the industry for a while. Window installers that have more years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.

    Beloit, WI Window Replacement FAQs

    What is the average cost to install windows in a home?

    The national average cost to install a single window is about $600 but can range between $200 and $1,200, depending on a variety of factors. The price is generally influenced by the location of your property, the size of the window and the type and material of the window. Also, remember that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.

    Which kind of window should I get?

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

    Can I replace my own windows?

    While you can install your own windows, doing so requires a lot of time and experience with home improvement projects. Using a window installation company can help ensure that the installation is done properly and that you can avoid spending the time and effort of doing it yourself.

    How long does window installation usually take?

    Each window takes around 30 minutes to install based on the type of window. However, the window installation can be a two-day job — or more — if you have a lot of windows that must be installed.
