Why you can trust EcoWatch

Our panel of energy experts work tirelessly to create unbiased reviews and informative content to help homeowners make educated decisions. No other windows site has covered energy efficiency and sustainability as long as EcoWatch, which means we're going to help you find windows replacements that will save on your energy bill and put more money back in your wallet.

Whether you're updating for aesthetics or have damaged windows, windows play a crucial role in conserving energy in your home. If you have old or damaged windows, your HVAC system could be working extra hard to heat or cool your home. This means spending more on electricity bills.

That’s also bad for the environment because the additional energy used by drafty windows increases your carbon footprint.

Efficient windows are particularly important in New Britain, where the temperature varies throughout the year. According to Energy Star, making the switch to energy-efficient windows can save the average homeowner up to $446 each year.

    How Installing Energy-Efficient Windows in New Britain Saves You Money

    By upgrading to energy-efficient windows, you and your family can benefit in several ways, including:

    • Decrease your carbon footprint: By using less energy after you switch to Energy Star certified windows, you’ll also be cutting your indirect greenhouse gas emissions by about 12%, according to Energy Star.
    • Save money on electricity bills: Once you upgrade to energy-efficient windows, you can see a reduction in your bills by about 12% because you’ll use less energy to heat or cool your home.
    • 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.
    • Protect your investment: When your home is on the older side, your windows could also be outdated or leaky. Upgrading your windows is an important part of maintaining your property and its value.

    Estimated Cost of Window Replacement in New Britain

    Windows come in varying shapes, purposes and styles, so costs and services will vary tremendously depending on several factors. Below, we go over the average cost and services that you’ll find from window installation companies.

    How Much Do New Windows Cost?

    Although the average cost of installing a single window is about $600, it can range from $200 to $1,200. But prices vary remarkably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also provide door replacements, which will add extra costs to your project.

    With windows, efficiency is the most important factor for most homeowners. Windows with higher efficiency may cost more upfront, but by increasing the efficiency of your home — especially during the summer and winter — they can give you decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save New Britain homeowners $446+ each year after replacing single-pane windows.

    We advise getting free quotes from multiple window installers to find the right windows and the company that works best for your budget.

    What Services do Window Installers Offer?

    When considering window replacements, in general there are two types that your installer will have: full-frame and pocket installations.

    Full-frame installations involve replacing the full window, including the frame, sill and trim. You most likely need a full-frame installation when you want to change the style of your windows or your window has considerable damage. Because these installations are more involved, they will raise the overall cost. Pocket installations are on the simpler end and won’t cost as much, as they entail merely replacing the window within its existing frame. But if the frame has any damage, you should opt for a full-frame installation instead.

    Your window installation company should be able to help you choose what’s best for your needs. In New Britain, the decision will mostly depend on how old your windows are and if there’s any moisture damage. Wood can decay if it’s not maintained properly over the years, so it’s good to have a professional evaluate your frames and window sills.

    How We Choose the Best Window Installers in New Britain

    In our hunt to find the most reliable, eco-friendly window installers in New Britain, EcoWatch chose the above companies as the best window installation companies in the city. Along with energy efficiency, we reviewed several window installers in New Britain and ranked them based on the following methodology:

    Service Area

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

    Work Quality

    When picking new windows, the quality and variety of services often plays just as important of a role in insulation and performance as the brand of window you get. We do give window installers higher marks if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

    Customer Reviews

    Another self-explanatory yet very important review factor is customer feedback. If the majority of customers don’t have positive feedback about their service from a certain installer, it won’t be featured on EcoWatch.

    Cost

    Cheaper windows certainly don’t mean better windows, but we know many of our readers want to keep costs as low as possible. When analyzing the prices of providers, we awarded higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.

    Warranty

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

    Years of Experience

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

    New Britain, CT Window Replacement FAQs

    How much should window installation cost?

    The typical cost to install a window ranges between $450 and $650. There are a variety of factors that affect how much it costs, including styles and sizes of windows, how energy-efficient the windows are, local labor costs, your property’s location, the materials used in designing the windows and the number of windows.

    What are the most common types of replacement windows?

    There are several different types of windows you can get for your home, such as awning windows, bay windows, slider windows, picture windows, casement windows, double-hung and single-hung windows and transom windows.

    Do you really need to use a window installation company?

    Unless you’re handy and have the tools needed to replace your own windows, we recommend hiring a professional installer. The process of installing windows is complicated and can take anywhere from four to six hours for one window. Although it’s tempting to try to save money by doing it yourself, hiring a professional is a faster, more efficient and much safer alternative.

    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. 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 the home, so the temperature outside doesn’t necessarily matter that much. What’s more important than the temperature is that the weather should be dry.

    Should I replace my windows all at the same time?

    If you’re upgrading your windows to get more efficient windows, replacing all of the windows together is the only way to see a noticeable difference. However, if you have only one or two windows that are broken or leaky, you can replace just those.
