You can probably have the drywallers spray on a fine texture (not quite orange peel) and cover the imperfections. 

If watching the grass die and the window screens disappear while they sneak in an unfixed that urinates & sprays all over the place doesn't bother you, go for it.  

sprayed the liquid insulation through the hole, it solidifies inside the block shortly.

We had a really bad situation that was more than likely intentional animal urine spraying from the previous (evicted) owners.

Spray the ceiling. it doesn't require any chemicals.

Peel and stick the patch, spread spackle, dry, sand, and use a can of spray on texture.As long as you can get the paint to match, nobody will notice the patch.

I'm not sure if it's best to mention the increasing requests, or simply to say why this one isn't valid.Their message was that there have been ants in the house, and they would like me to spray, or even TENT (!)

@JOAN DICKIE, I have a $100K rental in Jeff's neck of the woods and we plan to resurface the countertops with a spray on faux granite finish from one of the re-bath franchises, if that comes out well enough we'll do it again in a little higher priced property.

I once sold a house years ago that had equity in it to an investor.The seller was in financial hard times.The house was paid off but then used a loan from a predatory lender who was now trying to foreclose.So I listed for them with plenty of equity left.The seller ended up selling and still getting 15,000 from the sale.The lady had a few cats and then took in strays.The cats started breeding and then more cats showed up under the crawl space where the vent cover was broken and they would go in and out.There was at one point before I listed it 55 cats in there.Animal control came out and got 48 cats out,3 were dead,and 4 were too wild and ran out of the house.She kept most of them in one room and a few in the living room.I tried to help her by cleaning the room and used every cleaner imaginable.I don't care what people say about cleaners they don't work.The only time is if it's just a few place and the carpet pad and subfloor isn't soaked or they sprayed on the wall but not in the corner.If the urine gets under the baseboard or in the corner forget it.You will have to tear out the sheetrock in that area and clean behind it.For subfloor depending on how deep it has penetrated the wood you can sand the top surface off to get rid of the smell.If it's deep you have to rip the subfloor up and replace.What you need to do is take a portable black light and walk around every area inside of the house and outside to see where the marking has occurred.It it's simply the walls and not the floor or corner you can clean easily.You will know by the black light how extensive it is.

Then fills the under area with spray foam, and puts the 2x4's and drywall back up and done...
