@Fred ColcloughI would do a nicer plastic laminate that looks like granite. 

The tenant that just left replaced the living room windows with this weird plastic looking glass (not sure if it's glass) with weird designs all through it.

LOL rolodex sits prominently on your desk.. it has these little plastic sleeves you slide the business card in there it protects them from the elements.. then their is tabs so you can put them in alphabetical order then you simply thumb through them.. you can also get the ones that are spring loaded.. now those you have to write the info in.. slide the little button on the side to the letter U want to open up and it pops up and there is your contacts. 

DO NOT do the cheap plastic signs.  

[We provide moving boxes and 3mil thick contractor type plastic bags.]3.

It's worth it to me - even if it ends up that I'm the one paying for it.If it's a slow drain, I'll usually go over since it's something I can handle with one of those plastic Zip Strips or cleaning out the trap under the sink. 

She has the tenants remove all the plastic and take out a change of clothes and shoes, which she treats in a small box that she leaves outside the house before they leave for the day.  

Its much worse in the kitchen were I cant take out the floor right now but its like this plastic tile flooring.

The only thing i could ever figure is that water got trapped between slab and the plastic that goes down at construction and just slowely mitigates out, which might mean no water sensitive flooring for quite some time.

I would think plastic, sandbags and tape would do the same job as silicone to keep out rain and it would be a lot easier to remove after the storm.
