I will need to talk to the man that replaced the carpet but the urine had been there for at least 6 months with no attempt from her to clean it. The smell was really terrible, even when I bought the urine deodorizer spray, it did not work. I think that it soaked through to the padding and would of needed to be replaced regardless, but again I will need to talk to the man who replaced the carpet. It’s $293, which I know isn’t a lot of money but I just graduated college and need the money.
