Look beneath durable finishes
Tile and resilient flooring can hide a wet layer below while the walking surface dries quickly. Perimeter testing and access from an adjacent room or ceiling may reveal the subfloor condition with less disturbance. Openings are limited to locations supported by evidence.
Toilet wastewater changes the controls when contamination is present. Access is restricted, affected porous material is evaluated for removal and clean rooms remain separated. A clean supply leak follows a different handling plan even if it reaches the same floor area.
