I had asbestos tiles and mastic abated on a condo unit I bought.
After the abatement, the abatement contractor told me the fowl odor from the chemicals used to remove the mastic would dissapear. He knew I was having prefinished hardwood floors installed a few days after the abatement. He told me that would definitely help with the odor problem.
Well it's been three months and the odor is still there.
I've been airing out the place with fans which helps temporarily, then the odor returns.
