A retaining wall goes up course by course on a Colchester slope, each stone set until the line runs true and the hillside finally sits still — that is the kind of result this crew works toward. Affordable Services LLC handles light excavation on rubber tracks, grading for level yards and driveways, trenching, drainage and dry wells, lawn install and repair from the soil up, patios and walkways, concrete flat work, stone veneer, erosion control with straw mats and rock, and crushed stone pads leveled for a shed. In this stretch of eastern Connecticut — ridge woods and hayfield, old stone walls leaning into the trees, water always looking for somewhere to go — a swale cut right is the difference between a yard that drains and a yard that puddles all April. They also plow snow, so the same driveway they graded in July gets opened again in January, dark and cold and clear by morning. What they leave behind is meant to hold: ground that lies flat, water that moves where it should, seed that comes in green.
