Awhile back a leak that had been going on for who know's how long was fixed where the toilet tank meets the bowl. Now the problem is the water had leaked into the insulation of the boiler room below it and it stinks of mold. I thought the mold had taken care of itself soon after the leak had been fixed but it's been making itself known more and more lately.
The water got into the insulation by means of two parts of the linoleum behind the toilet not being well-sealed. Whoever put the linoleum down didn't do such a great job and left a strip in the middle behind the toilet which is now curled up abit.
My question is, do I have to replace the insulation once it is removed from the boiler room ceiling? Is it needed for fire prevention? If I just get rid of it, am I placing myself in danger by not reinstalling new insulation?
My landlady has ok'd hiring a day laborer to do the dirty work. I'm wondering if more professional help is needed, if I have to replace the insulation, or can anyone stuff new insulation back up? If so, do we need special insulation?
Thanks for any help.
