Tom Cwalinsky started K.O.S. in 2006 with a simple idea: when something goes wrong in your home, you should get a crew that shows up fast, tells you the truth, and does the job to the standard.
20 years later we have a bigger fleet, more certifications and more services, but we run the business the same way. Our crews live and work on Long Island. We answer our own phones. And we treat every job like it’s a neighbor’s house, because it usually is.
When disaster hits, we restore the property. When it’s over, we help keep it that way. One call, one team and one standard of work, from the emergency through to routine upkeep.

In the community
The towns that have trusted us for 20 years are the ones we live in, coach in and raise our families in. Giving back is how a local company is supposed to act. Here are a few of the causes we’ve been proud to support recently.
Island Harvest · Long Island
Island Harvest's annual Turkey Drive helps Long Island families put a holiday meal on the table, and it's become a K.O.S. tradition. Each November we fill one of our vans, deliver the food ourselves and add a cash gift so Island Harvest can reach even more families.

Longwood Lacrosse · Pickleball Haven
We were proud to sponsor the Longwood Varsity Lacrosse teams and LYSA Lacrosse at their fundraiser night at Pickleball Haven. Supporting local youth sports matters to us, and it was great to see so many families and young athletes come out.
Westhampton Beach Rotary · Westhampton Beach Performing Arts Center
K.O.S. was a Silver Sponsor of the Westhampton Beach Rotary Club's community event at the Performing Arts Center. Rotary's work runs from youth leadership and education to clean water projects and disease eradication. We're glad to support an organization that does so much, both here and around the world.
