A July thunderstorm over the Highlands hits Mahopac hard and fast, and by evening every lawn has grown an inch and every yard has a scatter of oak limbs. Superpower Home Improvement and Landscaping shows up after weather like that — mowing, trimming, cleanup, mulch put back where the rain moved it, hedges cut into line again. The seasons here are not gentle, and neither is the leaf drop or the snow behind it, so the winter side of the work is plowing, shoveling and salting drives and walks. What stays constant is the finish: nothing left ragged, nothing left in the road. Mahopac and its surrounding towns, storm to storm.
