Late-summer dusk in Woburn Square softens everything — brick going warm, the last mower of the day shutting down somewhere a few streets over. Sparkes Classic Services works those unhurried hours as much as the bright ones, mowing, trimming and edging until a lawn looks settled rather than simply short. Hedges are kept in line and beds cleared, and when the leaves start dropping the yards get taken down to a clean surface for the winter. The approach is old-fashioned in the good sense: turn up when you say, do the whole job, sweep the walk before leaving. Around the center of the city that kind of finish keeps a whole block looking cared for.
