I had the floor replaced and the guy put down a plastic barrier and used some "heavy duty" spray from Home Depot.

Melamine-coated MDF are very popular cabinets in a lot of areas, and can be expensive, despite the fact that they're sawdust inside of plastic.

Light fixtures – solid, rust proof metals (especially for moist areas such as bathrooms) rather than coated or plated (or plastic) fixtures.

To be safe with anything except a fairly new house, you’d really need to excavate around the house, parge the outside of the foundation with an asphalt/tar product, install a dimpled plastic membrane over that, and then on the inside, fastidiously install rigid foam on the floor and walls, spray foam/tape all seams, etc… Then frame, then drywall.Seems ungodly expensive.

my classic was the tenant complaining of mold around the windows.. go and check it out and they haveand they have ruined the blinds and put up foil and plastic and so you had all this moisture  and when the mold started they were scrubbing it and ended up ruining the sheet rock try to rub the mold out..  

If just yours are gone and others remain, it's being done by your competition.Full disclosure, in my area if I see one of those cheap plastic signs that says "We Buy Houses" on it, it is HISTORY

I just use little plastic tags.There are "landlord" locks available online that allow master keys, individual keys and easy changes.

If it is a local clog, better to use one of those "zip it" plastic tools from the box stores. 

If your remodeling to live in long term, go with the warm water and sprayer with plenty of plastic and rags.
