How much repair to to do yourself vs prop mgmt company

[Matt F.]

got word thru my mgmt company that 2 fairly minor efforts need fixed at my rental.  (one board on deck is warped pretty bad and isn't sitting flush any more, i don't want someone to trip and two, drywall paper around top of shower/tub insert is peeling back from water that slashed up there while showering.  solution in other shower was installing one row of 4X4 tiles and caulking.)  so two fairly minor repairs.  would you take this on yourself or pay prop mgmt company to handle.   THANKS
