Cops in the department use Nolan history in contracting.

Lucy gets Nolan to help her and temara(sorry kg I spelled her name wrong)  renovate her room.

Grey gets Nolan to help when his wife wants a renovation.

Nolan helps him and his sister with their old house and gets them more money than they though they would get when they sell the house

Nolan renovates Harper's house. Even putting in a hidden arsenal so she feels safe and it's protected so her kids can't access it.

And more

And Nolan goes to run down neighbours and fixes their kids playgrounds (like that one episode)
