Bought a house at a discount from a lady that 8 dogs that seemingly predominantly used the bathroom inside. The piss was enough to sting your eyes when you walked in. Pretty nasty stuff.
I really wanted to do a move-in ready home, seems like I always have to do a bunch of work to a place, but it's saved me some money.
Subfloor repairs were pretty significant, but it had to happen anyhow. 70's house with mdf under it that was piss logged, and I laid tongue and groove bamboo anyhow.
I got pretty nervous after demo because I was still getting a urine smell, but it's out now. Got most of the new floor in, but still gotta finish a closet and a bedroom.
Not a terrible project, ended up looking really nice. The bamboo is hard as a brick. Took some trial and error to get the stapler right to not split tongues but to also get the staple all the way through.
Yeah, there's some wood paneling in the laundry room, which also housed a welping box. I think I still get an occasional smell in there, but I can't tell if it's in my head. My wife claims not to smell it.
I'll never have carpet again after tearing this out. I'm skeptical of even having a rug. There was just so much piss and dog hair.
