Why you can trust EcoWatch

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.

Although clean energy sources like wind and solar are important when it comes to reducing your carbon footprint, improving your house’s energy efficiency can also have a large impact on home energy conservation. Drafty, leaky windows could lead to having higher power bills during the winter or summer months.

That’s also bad for the environment because the additional energy used by outdated windows increases your carbon footprint.

We’ve put together this list of the top installation companies to help you in your research, so you can not only take advantage of brand-new windows, but also save money on your energy bills.

    How Installing Energy-Efficient Windows in Waterbury Saves You Money

    Energy-efficient windows can offer benefits in more than one way. Here are some reasons you may want to take the plunge and make the switch:

    • Decrease your carbon footprint: Decreasing how much energy you use also lowers your carbon emissions. You could reduce it by 147 pounds per year on average.
    • Protect your investment: When you have an older home, your windows could also be outdated or leaky. Upgrading your windows is an important part of maintaining your property and its real estate value.
    • Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out harmful UV rays, reducing fading of your furniture, carpet and other valuables.
    • Save on electricity bills: Because energy-efficient windows reduce how much energy you need to heat or cool your home, they can help you save about $420 annually on your energy bills in Waterbury.

    Estimated Cost of Window Replacement in Waterbury

    Let’s go over the cost of installing new windows and the types of services offered by installers.

    How Much Do New Windows Cost?

    According to our research, the national average cost to install a single window is about $600. However, window replacement costs can range from $200 to $1,200 per window. How much it will cost varies based on several factors, like size, number of windows, material, the location of your home, type and more.

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

    Another factor that influences the total cost is the material of the frame you choose. Aluminum frames are usually the least expensive and are sturdy and relatively maintenance-free, but they provide poor insulation. On the other hand, wood frames are the most expensive, as they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.

    What Services do Window Installers Offer?

    There are generally two kinds of window replacement services: full-frame and pocket installations.

    A full-frame installation is a replacement of the full window. This service involves taking out the old window, the windowsill, and the exterior and interior trim. It also involves extra materials, including insulation and drip edges, which raise the overall cost of the project. Also worth noting: it’s not uncommon for homeowners to have to touch up the paint around the window after a full-frame installation. Pocket installations are simpler and won’t cost as much, as they entail simply replacing the window within its existing frame. But if the frame has any damage or rot, you may have to get a full-frame installation instead.

    Your window installation company can recommend the best type for your project. In Waterbury, the choice will mostly be based on how much damage there is currently and how old your existing frames are.

    How We Choose the Best Window Installers in Waterbury

    The EcoWatch Reviews team is different from most reviewers, as we’re examining these companies through a sustainability lens. Along with energy efficiency, we reviewed each installer and assigned rankings using the following methodology:

    Service Area

    Because this is a guide for Waterbury, we only included companies that cover the city. There are certainly other reputable providers that didn’t make the list because they wouldn’t be able to serve homeowners in Waterbury.

    Work Quality

    We’re certain that you’re looking for a company to do a great job installing windows. We’ve vetted each installer included on this list to make sure its technicians are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.

    Customer Reviews

    We analyzed trends in recent customer feedback to determine the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction might be the most important factor, as it reflects the quality of services across nearly every category, including cost, warranty, professionalism, quality of installation, quality of parts and more.

    Cost

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

    Warranty

    Protecting your investment in new windows is important. That’s why window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) 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 will earn higher rankings by our standards. We like to see at least ten years of experience.

    Waterbury, CT Window Replacement FAQs

    How much does a window install cost?

    The national average cost to replace a single window is around $600 but can range from $200 to $1,200, depending on a few different factors. The price is usually dependent on the size of the window, the type and material of the window and the location of your property. Also, remember that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.

    What are the most common kinds of replacement windows?

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

    Can you replace your own windows?

    Even though it is possible to install your own windows, doing so requires a lot of time and handiness. Using a window replacement company can help ensure that the job is done properly and that you won’t have to spend the time and effort to do it yourself.

    How do you know it’s time to replace your windows?

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

    Should I replace my windows all at once?

    If your windows are greater than 20 years old, it’s most likely time to replace all of them. By that point, they are usually less efficient, draftier and/or more damaged than new windows. Doing your windows all at once will involve less paperwork and less time.
