    How Installing Energy-Efficient Windows in Windsor Locks Saves You Money

    When you switch to energy-efficient windows, you may see some perks, such as:

    • Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes tend to have windows that are outdated, leaky or maybe even damaged in some way. Updating your windows could help increase the value of your property if you decide to sell.
    • Reduce your carbon footprint: Reducing the amount of energy you use also lowers your carbon emissions. You could reduce it by about 147 pounds.
    • Save money on electricity bills: The Department of Energy estimates that heat gained or lost via windows makes up about 25-30% of household energy use. Switching to energy-efficient windows can help decrease that amount, which helps you save more on your bills.
    • Protect your valuables from fading: When you upgrade to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will be protected from fading due to their ability to filter out damaging UV rays.

    Estimated Cost of Window Replacement in Windsor Locks

    Windows come in varying shapes and sizes, so costs and services will vary considerably. Here are the average costs and the primary services that you can find from the average window installation company.

    How Much Do New Windows Cost?

    Typically, homeowners in Windsor Locks can anticipate that most replacement window installations will range from $250 to $1,200, with the most common installations sitting at around $600. But costs differ remarkably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also provide door installations, which will add extra costs to your project.

    Whether or not you choose energy-efficient windows is another factor that will affect the cost. These will typically cost more than other windows, but on the other hand, you can save about $446 a year on your energy bills in Windsor Locks.

    Something else that influences the overall cost is the material you choose for your frame. Aluminum frames are generally the least expensive and are sturdy and light, but they offer poor insulation. On the other hand, wood frames cost the most because they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.

    What Services do Window Installers Offer?

    There are generally two types of window installation services: full-frame and pocket installations.

    A full-frame installation replaces the entire window, such as the sill, frame, trim and the window panes. Because this type of installation is more involved, it will cost more than a pocket installation. Pocket installations (also known as retrofits) are when you replace a window without replacing the frame. Pocket installations are on the simpler end and won’t cost as much, but you can’t do this kind of installment if you have any pre-existing rot or water damage.

    Your window installer should be able to help you figure out which type of installation you need.

    How We Choose the Best Window Installers in Windsor Locks

    In our hunt to find the most reliable, eco-friendly window installers in Windsor Locks, the EcoWatch team evaluated dozens of companies before landing on these. Along with energy efficiency, we reviewed several window installers in Windsor Locks and assigned rankings based on the following methodology:

    Service Area

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

    Work Quality

    We’re willing to bet that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each company on this list to ensure its technicians are well-qualified and that the company has received lots of positive customer feedback to vouch for its service.

    Customer Reviews

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

    Cost

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

    Warranty

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

    Years of Experience

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

    Windsor Locks, CT Window Replacement FAQs

    What is the average cost to install new windows?

    The average cost to replace a window can range between $450 and $650. There are several factors that affect how much it costs, which include the number of windows, your property’s location, local labor costs, styles and sizes of windows, how energy-efficient the windows are and the materials used in designing the windows.

    What are the most common types of replacement windows?

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

    Can I replace my own windows?

    Although you can install your own windows, doing so requires a lot of time and handiness. Using a window replacement company can help guarantee that the installation is done properly and that you can avoid spending the time and effort of doing it yourself.

    How often should you replace windows?

    Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, they probably need to be replaced. Apart from that, if your windows have any damage on them, or they have become difficult to operate, they may need to be replaced.

    How long does it typically take to install windows?

    Because the average installation time is 30 minutes per window, about 16 windows can be installed during a typical 8-hour work day.
