Window Repair Company Serving Long Island Since 2014

PRESTIGE Window Works was founded on Long Island in 2014 with a straightforward purpose: to provide Nassau and Suffolk County homeowners with professional window and door repair performed correctly, on time, and without the pressure to replace what can genuinely be repaired. Over a decade later that purpose has not changed — only the scale. More than 6,000 completed projects across Long Island. Two offices, one on the North Shore in Manhasset and one in central Suffolk in Hauppauge. A team that has handled everything from a single impact-broken pane in a Malverne Cape Cod to structural rot restoration on a Great Neck estate, from a through-glass dog door installation in Oakdale to a full skylight glass replacement on the North Shore.

We are local recommended window repair company in Long Island, NY. This is what we do, this is where we do it, and the 550+ five-star reviews from Nassau and Suffolk County homeowners reflect that focus.

Who We Are — A Long Island Window and Door Company

Prestige Window Works is a family-operated window and door repair and installation business based on Long Island, New York. We serve residential and commercial customers throughout Nassau County and Suffolk County from our two offices:

Manhasset, NY — our Nassau County office, serving the North Shore, the South Shore, and communities throughout Nassau from Great Neck and Port Washington to Freeport, Rockville Centre, and Valley Stream.

Hauppauge, NY — our Suffolk County office, serving communities throughout western and central Suffolk from Smithtown, Commack, and Nesconset to Bay Shore, Babylon, and Patchogue, and east toward the North Fork and South Fork.

Between these two locations, we provide the response times and local knowledge that Long Island homeowners deserve — not a company driving from outside the area that treats a job in Huntington the same as a job in Hempstead. We are fully licensed and insured in the State of New York. Every member of our field team is trained in the specific techniques required for the window and door repair work we perform — glass cutting, IGU replacement, wood frame restoration, mechanism repair, rot removal and epoxy rebuild. This is specialist work, and we staff it accordingly.



With decades of experience in repair and restoration of windows and doors, our team is dedicated to providing you with the highest level of service and quality. We take great pride in our work and are committed to delivering an exceptional customer experience. You can trust us to provide you with the best service and products for your home.
