Can anybody tell me how to say "there's a plumber coming tomorrow at 9am" in Polish?

[mawbroon]

I have some polish people staying in my flat and need to let them know about the plumber coming.

they hardly speak any english, so this would make it easier for them.

Going out now, but will look back later.

TIA
