Structural engineers are being called in to check five houses on the edge of a collapsed road.
A section of Calstock's Lower Kelly Road crumbled into the River Tamar on Christmas Day, forcing the temporary evacuation of adjacent residents.
It also left 38 other houses and three businesses further along the no-through road stranded.
Twenty-five cars still trapped may be moved by ferry or landing craft.
Resident Lyn Edwards, who has owned her home for 20 years was evacuated on Christmas day. She says it's an anxious time.
