Eliminating pet odors...????

[Clint G.]

I'm looking at a potential flip property that I might decide to BRRRR. Currently there are about 5 dogs inside and it smells like pet urine and poo all throughout the house, but mostly upstairs, which is all carpet.

Obviously the carpet has to go, but I'm worried that the plywood sub floor has been saturated with urine. Is there a way to get this smell out, or do you have to replace the sub floor? I plan to install tile or LVP in place of the carpet, so I thought about spraying a water/bleach mix on the sub floor and install after it dries. 

Thoughts?

I have a similar issue. Old tenant in house prior to my purchase had two big dogs that did their business all over the house. Now I need to get the smell out. I was told Killz Primer would help, but I'm interested to hear other people's point of view on this before I get started on it. Worst thing in the world would be to put new flooring down and not have the smell out. I have considered just putting down new subflooring. A relatively small expense for peace of  mind with the exception that it is time consuming and I'll likely have to get some help.
