In Rochester, New York, a homeowner started a bathroom renovation thinking the plumbing was fine. Once the walls were opened, a hidden leak was discovered that had already damaged the subfloor.
Contractors in the comments explained this happens more often than people think. Old homes or homes with previous DIY fixes are especially prone to hidden issues.
The lesson shared by the community: always inspect what you cannot see. Fixing problems early saves money, time, and stress during any renovation.
