Best practice in removing dog urine smell?

[Joseph Borges]

Big fan of biggerpockets but this is my first post. I recently purchased this house to convert into a duplex and BRRRR. Purchase price was great, the smell was not! There were 4 dogs in the house and they pi**ed everywhere. They are hardwood floors. I have been to Walmart and purchased 10 of the large baking soda boxes and spread throughout the house. I spread out 5 the first time and there were spots that soaked up some of the urine from the floor. I spread 5 more boxes and there is still urine coming out of the floor and the smell is still present. Any suggestions on getting the smell out? Thanks in advance. Thanks in advance for all your help.

There is a good chance that the hardwood and sub floor soaked up the dog urine, and may have to be replaced to do it possible. You may also do a deep clean and repaint the walls and ceilings. Sometimes the smell gets stuck on the surface and by cleaning and painting you can get rid of it. It may be worth trying that first, even if it doesn't work those items need done anyway. 

Good Luck! Aaron
