About Signature Windows 

Signatyre Karey Kassl Manufacturing Quality Windows & Doors since 1947 

Signature  Windows and Doors Mfg. Corp,  is one of New York’s  Oldest and well known Window Manufacturer and Installer. We fabricated and installed for the public and private sectors, on both, commercial and residential projects for many years. We have a well known reputation for service, quality and value and we are recognized as one of New York’s top window companies, known for providing upscale, high class service with “easy on the pocket” prices.  For many years later, Signature Windows & Doors  counts more than 50,000 satisfied cost-effective customers in every corner of the tri-state area .

Not Just another Window Company

It is surprising to see how many window companies will come and go over the years. In fact, some of the New York’s biggest window companies engage in a practice of “hide the ball”: they change their name and obtain a new license every few years in an effort to “wipe the slate clean” after too many complaints and weak reviews have piled up to taint their current business name. Not us, Signature Windows & Doors  We stand by our work and back up every job we have ever done. We are in business for the long-haul, not the short-gain.

Our integrity, our quality and our client satisfaction are the most important aspects of our business and we do everything possible to maintain and reinforce that.

We’re Home Grown

Signature & Doors Windows is a community-based, locally owned business. Signature Windows & Doors  Headquarters and manufacturing facility is strategically located in Greenpoint, Brooklyn, New York, minutes from any project in the New York City area.

Our employees live all over New York in many of the communities that we service. We are your friends and neighbors. All of us at Signature Windows & Doors understand the jitters that some folks may have when it comes to home improvement projects. So we do everything we can to make this a “jitter-free” experience and to help you turn a home you like into the home that you love.

Simple System

Our system is simple. We combine the personal touch and customer-service values of a family-run company with the state-of-the-art products and smooth, efficient business operations of much larger companies. Our sales associates and project coordinators personally consult with each homeowner to develop ideas and solve design challenges in the best, most honest way. We listen. We are  by your side through every step.

No Subcontractors

We use no subcontractors-only our own expert installers, all of whom have been with us for years and years. When you deal with Signature Windows & Doors , you deal directly with us and our people-not with any subcontractors, overnight hires or “here-today-gone-tomorrow” types. We all here at Signature Windows & Doors are considerate, respectful, responsible , punctual as well as  professional manner. We clean up after ourselves, no mess is left behind. It seems like a simple formula, but it is astonishing to see how many companies fail to meet these standards.

We can provide you with all of the information you need to accurately describe your project and apply for any and all of the approvals that you might need.
