How difficult asbestos remediation can be depends a lot on the situation. Regardless of the situation people working near or on asbestos require respirators, bunny suits, many vacuums, and more to handle asbestos safely. Not the best conditions to work in but definitely not the worst.

Where the work is being done says a lot about how difficult it'll be. As an example take a single detached house, asbestos remediation wouldn't be too difficult. The residents can leave the home so there's less concern about inadvertently exposing the public. It gets a lot more difficult when the work is being done in say a train terminal for example. The terminal cannot be closed for a month so work must be done alongside the public. Now a whole system needs to be put it place. It becomes a lot easier to just leave the asbestos alone, as long as it's not turned into a dust it's not dangerous.
