Said It Here

Contractor ghosted me with a leaking steel shed floor

The contractor failed to install the damp proof membrane correctly up the walls, leaving the steel shed floor damp and prone to leaks during storms. With the contractor now refusing to return calls, the homeowner is left trying to figure out whether part of the concrete floor needs to be pulled up to fix the issue.

“Anything I can do if he's ghosted me? Will I need to pull up part of the concrete floor where it is leaking?”source ↗
