Leak location companies are typically available in most areas. Leak locators are useful when a pipe has a slow leak in a wall or in the slab. Leak location is typically not a service provided by water damage companies.
Leak location services are most commonly used when the leak is in a pipe inside the foundation of a home. Most leak location companies not only find the leak typically through acoustics but also dig in and repair it the same day. Leaks can often be repaired at the same time the house is being dried.
