    Oxford Window Cost Calculator

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

    There are several perks of upgrading to energy-efficient windows. A few reasons you may want to consider making the switch include the following:

    • Reduce your carbon footprint: Because energy-efficient windows improve the insulation in your house, you can cut your carbon footprint by about 12%, according to Energy Star.
    • Save on power bills: The Department of Energy estimates that heat gained or lost through windows accounts for around 25-30% of household energy use. Switching to energy-efficient windows can help lower that number, which helps you save more on your bills.
    • Protect your investment: When your home is on the older side, your windows could also be outdated or leaky. Upgrading and repairing your windows is an important part of maintaining your property and its value.
    • Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.

    Estimated Cost of Window Replacement in Oxford

    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, Oxford homeowners can expect their window replacements to range from $250 to $1,200. The most common installations sit at approximately $600. But prices vary considerably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also offer door installations and replacements, which carry a higher price tag.

    With windows, efficiency is the most important factor for most homeowners. Efficient windows may cost more off the bat, but by increasing the efficiency of your home — particularly during the summer and winter — they can provide decades of energy savings. According to Energy Star, buying certified energy-efficient windows can save Oxford homeowners $420+ per year after replacing single-pane windows.

    How much your window installation costs will also vary based on the type of material you choose for the frames. Wood windows are generally the most expensive, although it depends on whether they are 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are more efficient.

    What Services do Window Installers Offer?

    Generally, there are two kinds of window installation services you can get: full-frame and pocket installations.

    A full-frame installation replaces the entire window, such as the windowsill, frame, trim and the window panes. As this type of installation requires more time and labor, it will be more expensive than a pocket installation. A pocket installation means replacing a window within the existing frame, which is generally cheaper than a full-frame installation.

    If you’re hiring a reputable window installation company, your company can advise you on the best type for your project. In Oxford, the decision will mostly be based on how much damage there is currently and the condition of your existing frames.

    How We Choose the Best Window Installers in Oxford

    EcoWatch reviews differ from most reviews because we look at these companies through a sustainability lens. Along with energy efficiency, we analyzed window companies all across the state and assigned rankings based on the following methodology:

    Service Area

    This one is self-explanatory, but we’ve chosen to highlight window installers that serve a wide variety of states and cities so you can find a quality window installation company near you.

    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 get. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

    Customer Reviews

    We analyzed patterns in recent customer feedback to find the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it reflects the quality of services across most other categories, including quality of installation, cost, warranty, quality of parts, professionalism and more.

    Cost

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

    Warranty

    Protecting your investment in new windows is important. That’s why 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 experience earn higher rankings by our standards. We like to see at least ten years of experience.

    Oxford, CT Window Replacement FAQs

    How much should a window install cost?

    The average cost of installing one window ranges between $450 and $650. There are many factors that affect the cost, which include how energy-efficient the windows are, local labor costs, styles and sizes of windows, the number of windows, your property’s location and the materials used in designing the windows.

    What are the most common kinds of replacement windows?

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

    What services do window replacement companies offer?

    Window installers go to your home to remove your old windows and replace them with new ones. Some companies install products sold 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. Regardless of 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 isn’t necessarily a big factor. What’s more important than the temperature is that the weather should be dry.

    How long does window installation generally take?

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