You can hear the Androscoggin working over the falls from a good part of Livermore Falls, and in January that sound comes up through ice and steam. Duck Daddy Contracting keeps the properties above that bank clear — plowing driveways and lots, opening walkways, and pushing the banks back where the wind funnels along the water. In summer the same routes turn green: mowing, trimming, edging, and cleanups in spring and fall. River-town yards run in odd shapes, cut up by ledge and old foundations, and getting them right means knowing each one. The reward is a place that looks tended no matter which month you drive past it.
