A manufactured home repair contractor fixes a soft floor: cutting out the damaged subfloor, fixing the cause, and laying new subfloor and flooring.
Short answer: A soft spot means the particleboard or plywood subfloor got wet and lost its strength — under a window, at a door, around the tub and toilet, or over a torn belly wrap. The repair is straightforward: open the floor, replace the wet subfloor with plywood, and refinish. The part that matters is the cause, because new subfloor over the same leak is soft again in two years. A repair contractor who works on manufactured homes knows the floor system, the belly wrap and where the water usually comes from.
