If you call a qualified professional to work on your home, in most places they should be insured and offer some form of guarantee.
Home improvement jobs do not offer this protection.
For a job that you know you can do without endangering anyone, it’s probably not worth hiring a professional for the job.
In all other cases, however, the extra money you might spend to hire someone is usually worth the investment.
Consider the cost of tools and protective gear you may or may not have and the cost of acquiring them when making your decision.
