carpet cleaning

[ftpolk1970]

what can happen to the sub-floor, padding and carpet in a bedroom when the carpet is professionally cleaned 3 times within a 2 week period?

It can all get very, very clean.

If you had to have it cleaned three times in two weeks, I'd say that the cat piss smell is never going to come out.

Remove and discard all carpeting and padding , then give the whole floor six months to air out.

remove and clean perfectely. let dry till very dry, add extra heat to room.

then apply 2 coats of OUTDOOR POLYURETHANE. it will seal the stink in the wood permanetely

When I bought my fixer-upper house in 1979, after I removed the stinking carpeting and pads. I decided to just let it air out.

I mopped it once a week with some kind of enzyme that was supposed to break down the urine smell. I don't know if it did any good or not but eventually the smell went away.

Though I did not think to use polyurethane, I wonder if the odor would just have come out the bottom?
