Getting rid of pet odor (urine)

[Gary Marcotte]

I have a HUD home under contract and when I did my initial walk-thru there was a heavy pet odor in the house. Not just musty dog smell but a stronger one, like urine. Not sure if it is dog or cat or both. I believe it to be all the way through to the sub-floor (plywood). Was wondering if anyone has a remedy or experienced any trial and error ways of getting rid of it? I'd like to avoid a costly "professional" cleaning if possible and/or a lot of trial and error of my own.

Any help would be greatly appreciated.

Painting the subfloor with oil based Kilz can fix the problem, but if it is really bad you may want to just replace that section of subfloor. If you can isolate where it is concentrated, a few sheets of plywood will fix you right up for not much money.
