Lower Falls sits at the elbow of the river where Newton meets Wellesley, and in January the wind comes up that valley with the snow out in front of it. Do Right Maintenance, Inc handles what the wind leaves behind, plowing drives and lots, clearing walkways and doorways by hand, and putting down salt and sand where damp ground and shade conspire. Storms here rarely end politely: there is the fall itself, then the wall the town plow leaves at the curb, then the refreeze at dusk. Coming back for the second and third pass is most of the job. The point of all of it is a property nobody has to think about.
