Like the other answers said, it depends on how bad the damage is, the difficulty level in fixing it, and whether or not there's an expensive part to be replaced. For instance, it's far cheaper to fix a leaky faucet than a water heater problem.
When looking for contractors, you might want to check their licenses, experience, and reviews. Even if your budget might be tight, it's best not to book the first one you've encountered just because they're cheap. At the same time, you might want to ensure that their cost is reasonable for the services to be rendered and any parts that should be replaced.
