20 Best Window Companies in Manhattan, NY (2025 Reviews)

How Installing Energy-Efficient Windows in Manhattan Saves You Money

Energy-efficient windows can benefit you in several ways. Here are a few reasons you may want to think about making the switch:

• Save on electricity bills: The Department of Energy estimates that heat gained or lost through windows makes up around 25-30% of energy use in your home. Switching to energy-efficient windows can help reduce that amount, which helps you save more on your bills.
• Protect your valuables from fading: When you upgrade to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will be protected from fading due to their ability to filter out damaging UV rays.
• Reduce your carbon footprint: Because energy-efficient windows improve the insulation in your home, you can reduce your indirect greenhouse gas emissions by about 12%, according to Energy Star.
• Protect your investment: If your home is on the older side, your windows are most likely outdated. Upgrading your windows can make your home more comfortable and also help increase the value of your home if you decide to sell.

Estimated Cost of Window Replacement in Manhattan

When considering window installation, each company provides varying services and costs. Let’s go over some average costs and services.

How Much Do New Windows Cost?

Even though the typical cost of installing a single window is about $600, it can range anywhere from $200 to $1,200. 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 and replacements, which will make your project cost more.

Whether or not you pick energy-efficient windows is another factor that will influence the cost. These will almost always cost more than other windows, but on the other hand, you can save about $329 a year on your energy bills in Manhattan.

What Services do Window Installers Offer?

The first thing to ask yourself when considering a window replacement 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 windowsill, and the exterior and interior trim. It can also involve extra materials, like insulation and drip edges, which increase the total cost of the project. It’s also worth noting that 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 replacing a window within the frame that’s already there. So, instead of removing the whole unit and rebuilding it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.

Your window replacement company will be able to help you choose what’s best for your needs. In Manhattan, the decision will mostly depend on how old your windows are and if there’s any moisture damage. Wood can decay if it’s not properly maintained over the years, so it’s a good idea to have a professional examine your frames and window sills.

How We Choose the Best Window Installers in Manhattan

In our search to make your home improvements easier and more eco-friendly in Manhattan, the EcoWatch Reviews team chose the above companies as the top window installation companies in the city. Along with energy efficiency, we analyzed each installer and assigned rankings based on the following methodology:

Service Area

Because this is a guide for Manhattan, we paid more attention to companies that provide services to the city. There are certainly reputable providers that didn’t make the cut because of the low odds that they would serve the average homeowner in Manhattan.

Work Quality

We’re willing to bet that you’re looking for professionals who do a great job installing windows. We’ve vetted each installer featured on this list to ensure its technicians are well-qualified and that the company has received tons of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed trends in recent online reviews to find the companies with the highest rates of customer satisfaction. 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, quality of parts, professionalism, warranty and more.

Cost

This one is a give-and-take: as with most services, cheap window installers may not provide the highest 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 have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

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