By late October the maples on Sauk Village's side streets let go all at once, and a lawn that looked fine on Friday is gone under gold by Monday. Perfect Lawn meets that season with the same steadiness it brings to July: mowing, trimming, and clearing leaves off so the turf can breathe its way into winter. This is flat ground, prairie under the pavement, and a well-kept yard reads all the way from the far end of the block. Between the last cut and the first hard freeze there is a short window when everything can be put right, and that window is worth keeping. Serving Sauk Village and nearby communities on the state-line side of Cook County.
