Stella is a skilled plumber. Recently she was out of work. She promised to fix some leaky taps for her neighbour Bert. If Stella does not do a good job fixing the taps but actually makes them worse, causing water damage to Bert's house, what are Bert's legal rights? O Renovations are risky and Bert assumed the risk of damage, so he has no remedies. O There are no contract remedies, but Bert may have tort remedies in this case. O Bert's rights are governed by the law of contract. O Stella's promise was gratuitous so she owes Bert nothing
