It’s best to use someone who is repeatedly doing what you’re trying to doDon’t go to an eye doctor for hand surgery. although doctors are usually smart enough to tell you it’s not what they do. 

I prefer thicker, hard plastic tongue & grooves to paper/cardboard/rubber as they seem to stay locked together better over time. 

Just make sure there is enough space for absorption that the next neighbor down the hill is impacted.The house probably has an original foundation drain,  if an older home probably concrete tiles,  if newer some kind of plastic.   

It isn't brain surgery.

It also helps that I inform my guests that a starter supply of paper and plastic items are provided and ask them to replace any items they have used up. ( This may not be popular with others but I have never had a complaint and for the most part,  items used are replaced)

One renter recently had foot surgery and is now on crutches.

My sister in law had heart surgery. 5 people to a room.  

I kocked out the plastic plug with a screwdriver and am waiting on  a cycle to complete to make sure that was the only problem.I called the new to me handyman and he said there is a knockout plug?

I don’t know of any contractors who would do more than hang plastic sheeting over open entrances, maybe on a good day they might block a heating vent if you’re lucky.after I’ve had all the demo and drywall done, I have a cleaning lady I know come in to clean every surface, ceiling to floor.
