Every Sterling Heights lawn has its casualties: the strip along the driveway apron that salt burned, the thin patch under the silver maple, the ruts that appeared the winter somebody parked on the grass. Lawn Repair Guy takes those on. Bare-spot repair, overseeding, soil and grade fixes, plus the ordinary mowing, trimming and edging that keeps a recovery honest. September is the month for it in this part of Michigan — warm soil, cool nights, rain that finally means it — and a patch put down then is a lawn by May. There is genuine pleasure in watching a bald spot fill in until nobody remembers it was ever there.
