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

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

        • Protect your investment: If your home is on the older side, your windows are most likely outdated. Updating your windows can improve the insulation in your home and also help raise the value of your home if you decide to sell.
        • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only insulate your home better, but also filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
        • Reduce your carbon footprint: In New Haven, you can cut your indirect greenhouse gas emissions by about 147 pounds per year when you upgrade to energy-efficient windows.
        • Save on electricity bills: After you upgrade to energy-efficient windows, you can expect a reduction in your bills by about 12% since you’ll require less energy to heat or cool your house.

        Estimated Cost of Window Replacement in New Haven

        When looking into window installation, each company provides different services and prices. Let’s go over some typical costs and services.

        How Much Do New Windows Cost?

        According to our research, the average cost of replacing a single window is around $600. However, window replacement costs can range from $200 to $1,200 a window. Costs will differ significantly depending on the quality of your products, your location, the number of windows you need and the current condition of your home. A lot of window companies also offer replacement door installations and other add-ons like shutters, baths, coating and more. These extra services will increase overall project costs.

        It’s important to keep in mind that windows with the best efficiency may cost more initially but can save you hundreds of dollars by decreasing your energy bills. Investing in Energy Star certified windows can save New Haven homeowners $420+ a year when replacing single-pane windows.

        We advise getting free quotes from several window installation companies to find the right windows and the company that works best for you.

        What Services do Window Installers Offer?

        The first question to ask yourself when getting new windows is: Do you want a full-frame installation or a pocket installation?

        A full-frame installation is a total window replacement. It involves removing the old window, the sill, and the exterior and interior trim. It also involves other materials, like insulation and drip edges, which increase the overall cost of the project. Also worth noting: it’s not uncommon for homeowners to have to touch up the paint surrounding the window after a full-frame installation. A pocket installation entails installing a new window within the existing frame. So, instead of removing the whole unit and rebuilding it, the contractor will just slide the replacement window (also called a retrofit or insert window) into the frame.

        If you’re unsure which kind of window installation service you should get, your installer should be able to advise you. In general, the decision is based on factors such as the age and condition of the home, the type of building material, budget and time restrictions.

        How We Choose the Best Window Installers in New Haven

        In our search to make your home improvements easier and more eco-friendly in New Haven, EcoWatch evaluated dozens of companies before landing on these. We’ve decided to review the top window replacement companies in New Haven mainly 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 can reduce your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

        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 a quality window installation company near you.

        Work Quality

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

        Customer Reviews

        Another self-explanatory yet very important review factor is customer feedback. If most customers don’t have nice feedback about their service from a certain installer, 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 hefty investment, so you’ll want to be certain that investment is protected. Window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.

        Years of Experience

        Because of New Haven’s climate, homeowners will want to mitigate low efficiency, rot and water damage. We factored in local experience to reflect the ability of New Haven 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 Haven, CT Window Replacement FAQs

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

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

        What are the most common types of replacement windows?

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

        What services do window replacement companies offer?

        Window installers travel to your house to remove your old windows and replace them with new ones. Some providers install products manufactured by other companies, whereas others install their own windows. The installer will also clean up after the installation.

        Should I replace my windows all at the same time?

        If you’re upgrading your windows because of energy-efficiency, replacing all of the windows at once is the only way to see a noticeable difference. On the other hand, if you have just one or two windows that are damaged or drafty, you can replace just those.
