Bucks Hill does not forgive a lazy plow. The grade is steep, the wind funnels down the side streets, and a driveway left half-finished at two in the morning is an ice rink by seven. Chris Stupak Enterprises LLC runs those storm hours — pushing snow back to the banks, shoveling out the steps, and salting the pitch so a car can get down and a mailbox can be reached. In the warm months that same attention goes to grass: mowing on schedule, trimmed borders, sharp edges, and a cleanup at each end of the season. Waterbury is a city built on hillsides, and hillsides pay back anyone willing to work them properly.
