• Decrease your carbon footprint: In Mahwah, you can lower your indirect greenhouse gas emissions by about 73 pounds per year when you upgrade to energy-efficient windows.
• Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.
• Save on electricity bills: Since energy-efficient windows reduce how much energy you need to heat or cool your home, the switch can help you save around $285 annually on your energy bills in Mahwah.
• Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes tend to have windows that are outdated, drafty or maybe even damaged in some way. Upgrading your windows could help increase the value of your home if you decide to sell.

How Much Do New Windows Cost?

Whether or not you choose energy-efficient windows is another factor that will determine the cost. These will typically cost more than other windows, but on the other hand, you can save about $285 a year on your energy bills in Mahwah.

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

What Services do Window Installers Offer?

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

Full-frame installations are necessary when you want to change the style of your windows or your window has significant rot or deterioration. With this service, your professionals will replace the entire window, including the trim, frame and sill. Pocket installations are simpler and won’t cost as much, as they entail merely replacing the window within its existing frame. But if the frame has any damage or rot, you should opt for a full-frame installation instead.

Your window installer can help you choose which type of installation you need.

Service Area

This one is pretty self-explanatory, but we’ve chosen to highlight window installers that serve Mahwah so you can find the right window installation company near you.

Work Quality

When choosing new windows, the quality and breadth of services can often play just as important of a role in overall efficiency and performance as the brand you opt for. We do give window installers more points if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

We analyzed patterns in recent customer feedback to determine the companies with the most customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it reflects the quality of services across most other categories, including cost, professionalism, warranty, quality of installation, quality of parts and more.

Cost

Cheaper windows certainly don’t mean better windows, but we know many of our readers try to keep costs as low as possible. When analyzing providers’ prices, 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 to many homeowners. For that reason, window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.

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