Finally, the patio cement slab (about 500sq ft) has to go.

Finally I used gallons of paint stripper, poured that on let it sit for a bit and it actually lifted the cat pee right up into a yellow foam.. and that actually took it off the cement floor.. we after several months using various products and then odor killers... found Odor medic to work the best for us.. along with Ozone machine..Final finish to cement was we painted with a cement sealer paint. 

Note that Colton Cook stated how it should be done - the first step being laying a self-leveling cement.

But, grass and weeds are growing through the cracks of the driveway cement.

first, i think the quote was way over the top to jack up the floor, fix the pex and then pour in new concrete. but since you agreed, that's what you owe them. they had no idea that the tunnel was there and it's unfair to expect them to fill up the huge hole. now, if they did not replace the pex and did not pour new cement, that's their loss and i'd deduct. i'll pay them $500 if all they did was jack hammer the old stuff.

Specially the garage and replacing some cement entry steps along with some other minor things.Thanks!

What happens if the tenant flushes cement mix down the toilet when they get evicted?

If it were me.. 8.00 bucket of hydraulic cement and 50.00?

The numbers aren't great, but it's the relationship with this seller and agent that I'm hoping to cement. 

I contacted the title company to have them try and find the agreement.  10k is a rough estimate because the shed is attached to my garage and it's also on a cement pad.
