Recording phone call is illegal in PA but

Hi all, I've done 2 flips so far, and I have a question which might be related with law-side about doing business with handymans.

I recently finished one flip with my handyman and he delayed kind of every time for each phrase even though he said I will do this by this day, that day by calling..., so I feel like I should've put a term for clear deadline in a contract. (which was actually my fault that I had to put deadlines for each phrase in contract at the beginning...)

And the thing is that he doesn't want to leave text messages about deadlines, but want to give info about it by calling, so not sure if that is something he is trying to avoid leaving provement as here it is PA which state doesnt allow voice recording unless each party both agree. 

In this situation, for next project, if I put a term that says "the client and handyman both agree recording of phone calls for potential provement" in a contract, is that going to work & be helpful to me to file them once something happens between us in law-wise even in PA?

Not sure if anyone can answer this.
