How Installing Energy-Efficient Windows in Summit Saves You Money

By upgrading to energy-efficient windows, you can enjoy several benefits, such as:

• Reduce your carbon footprint: By using less energy once switching to energy-efficient windows, you’ll also be reducing your indirect greenhouse gas emissions by about 12%, according to Energy Star.
• Save money on electricity bills: According to the Department of Energy, heat gained or lost through windows accounts for around 25-30% of residential energy use. Switching to energy-efficient models can help decrease how much energy is used in your home, therefore saving you about 12% more on your bills.
• 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 fading of your furniture, carpet and other valuables.
• Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its real estate value, particularly if you have an older home.

Estimated Cost of Window Replacement in Summit

When looking into window installation, each company offers different services and costs. Let’s look at some average costs and services.

How Much Do New Windows Cost?

Typically, homeowners in Summit can anticipate that most replacement window installations will cost between $250 and $1,200, with the average cost at around $600. These numbers vary based on the specifics of your installation, like number of windows, type, material, the location of your home, size and more.

It’s important to remember that windows with the best efficiency may cost more initially but can save you hundreds of dollars by lowering your energy bills. Investing in certified energy-efficient windows can save Summit homeowners $295+ a year when replacing single-pane windows.

The cost of your window installation will also vary based on the kind of window 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 somewhat more expensive than vinyl, but they are more efficient.

What Services do Window Installers Offer?

The first question to ask yourself when planning a window installation is: Should you get a full-frame installation or a pocket installation?

Full-frame installations involve replacing the full window, including the frame, trim and sill. You most likely need a full-frame installation when you want to change the style of your windows or your window has significant damage. Because these installations are more involved, they will raise the overall cost. A pocket installation involves replacing a window within the existing frame, which is generally less expensive than a full-frame installation.

If you’re not sure which kind of window installation service you should get, your installer can advise you. Generally, the decision is influenced by 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 Summit

EcoWatch differs from most reviewers because we examine these companies through a sustainability lens. We’ve assessed the best window installation companies in Summit mostly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows can cut 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 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 selecting new windows, the quality and range of services can often play just as important of a role in insulation and performance as the brand you opt for. We do rate window installers higher if they offer high-quality products, but we also factor in 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 factor we place the most value on, as it indicates the quality of services across nearly every category, including cost, quality of installation, professionalism, warranty, quality of parts and more.

Cost

This one is a give-and-take: similar to most services, cheap window installation companies are not going to provide the most quality service. On the other hand, we want to ensure 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 to many homeowners. That’s why window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

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