Snellville has a golf course tucked in among its neighborhoods, and anyone who has driven past Summit Chase knows what a striped fairway does to a person. PorterHouse Lawn brings that instinct to residential yards — a clean cut, a defined edge, the mow lines laid so they read straight from the curb. Trimming around trees and fences, then the drive and walks cleared, and the yard is done. A Friday cut holds the whole weekend, which is largely the idea. Lawn care in Snellville and the towns next door.
