professional testing for gas lines in flip

[Kay Ferdous]

We are buying a house to fix and flip. Is there a way to test the whole house for gas leaks once we are done.  I do not want to go the DIY route but would like to have a professional plumber do the same and document it . What are my options and what should I ask when i am talking to the plumber . 

There are no gas leaks that I smell but would like to get a professional opinion and doucument it
