August evenings in Thornton stretch long and gold, and the shrubs along a front walk throw shadows halfway to the street. Angel's Lawn Maintenance Inc. works that shape — hedges and bushes trimmed to hold their line, grass cut and run close at the foundation, edges kept honest where lawn meets concrete. Weekly maintenance through the growing season keeps a property from ever getting away from the people who own it, which is far easier than rescuing it later. The heat that settles over the south suburbs in midsummer makes for early starts and plenty of water, and the day gets planned around it. What lasts is the look of the place at dusk: even, deliberate, unhurried.
