Right of entry during repairs

[Jared Tillery]

I have a ceiling and wall repair I am making in a unit. The tenant has become very difficult to deal with. I have sold her repairs we be ongoing and people will stop by periodically. We said we would giver her as much notice as possible. She posted a sign saying she must be notified before the may enter and attempted to lock us out of the unit. She is now saying she wants an attorney but I have not been contacted. Do I have the right to enter as I need and do repairs? This is in Milwaukee WI.
