How Installing Energy-Efficient Windows in Brooklyn Saves You Money

Upgrading to energy-efficient windows can help improve the comfort of your home and help you save on power bills. Here are more ways switching out your windows could help you:

• Decrease your carbon footprint: You can reduce your carbon footprint by about 12% once you install Energy Star certified windows. In Brooklyn, that’s about 154 pounds per year on average.
• Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
• Protect your investment: When you have an older home, your windows could also be outdated or leaky. Upgrading and repairing your windows is an important part of maintaining your property and its value.
• Save on energy bills: Since energy-efficient windows reduce the amount of energy used to heat or cool your home, they can help you save around $326 annually on your energy bills in Brooklyn.

Estimated Cost of Window Replacement in Brooklyn

Let’s take a look at the cost of installing new windows and the kinds of services you may need for your home.

How Much Do New Windows Cost?

On average, homeowners in Brooklyn can expect that most replacement window installations will cost between $250 and $1,200, with the average cost at about $600. But prices vary considerably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also offer door replacements, which will make your project cost more.

With windows, efficiency is one of the most important factors for many homeowners. Efficient windows may cost more off the bat, but by increasing the efficiency of your home — especially during the summer and winter — they can provide many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save Brooklyn homeowners $326+ a year after replacing single-pane windows.

Getting free quotes from multiple companies is the best way to figure out which one will work best for your budget.

What Services do Window Installers Offer?

The first step of a window replacement is to figure out whether you need a full-frame or pocket installation.

A full-frame installation replaces the entire window, including the windowsill, frame, trim and the window panes. Because this kind of installation requires more time and labor, it will cost more than a pocket installation. A pocket installation entails replacing a window without replacing the frame. So, instead of taking out the whole unit and rebuilding it, the window installer will just put the replacement window (also called a retrofit or insert window) into the frame.

Your window installation company should be able to help you choose which type of installation you need.

How We Choose the Best Window Installers in Brooklyn

EcoWatch reviews differ from most reviews because we examine these companies through a sustainability lens. We have reviewed the best window replacement companies in Brooklyn mostly 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 have been shown to cut your energy 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 Brooklyn so you can find a quality window installation company near you.

Work Quality

When picking new windows, the quality and breadth of services often plays just as important of a role in insulation and performance as the brand of window you opt for. We do give window installers higher marks if they offer high-quality products, but we also factor in 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 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 the prices of providers, we awarded higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

Protecting your investment in new windows is important to many homeowners. That’s why window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Last but not least, we like to see companies that have a good track record in the industry. Window installation companies that have more experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
