J Koz Enterprises was started by Jake Kosmider while he was in high school, with a push mower and door-to-door requests in his own Westfield neighborhood. Several of those first customers are still on the schedule.
The company has grown almost entirely through referrals from existing customers. The name comes from Jake's nickname, J Koz.
Jake is from Westfield and his family still lives in town. He personally mows every lawn the company services. Cleanups, mulching and junk removal are completed by Jake together with his crew.
All estimates are free. Jake visits the property and prices the job before any work is scheduled.
Calls and texts are returned the same day or the following day.
Cash, check, Venmo and Cash App are accepted. Credit cards are not.
The company does not offer snow plowing, to keep its trucks in service for the rest of the year.
