One Crew for Your Business Property or HOA Community

Property managers and HOA boards get one local crew that keeps the grounds consistent from the first spring cleanup through fall leaf removal. We maintain office parks, retail properties, and HOA common areas, from weekly mowing and bed care to seasonal color, drainage fixes, and grading when water is the problem.


Our corporate landscape maintenance programs cover ongoing contracts, and our commercial landscaping services handle new installations and upgrades. See the commercial properties we have completed around Lancaster County to judge the finished work yourself.


Keystone has served Lancaster County since 1990, holds PA Contractor #34014, and is a member of the Snow & Ice Management Association (SIMA). As a local business based in Mount Joy, we’re your neighbor, not a franchise.
