Asbestos Tiles on wood floors with no sub floor

LTTNJuly 9, 2014

I am renovating my kitchen. There was awful laminate above tiles and original vertical grain pine below the asbestos tiles. Most of it is still down, apart from some tiles I pulled up that were under the base cabinets on one side and not covered by the laminate.

Here's the thing...there is no sub-floor under the true 3/4" wood floors. I have a subterranean garage which all of the original house is built above...like a walk out basement. When we sanded the LR and BR floors, it coated everything in the basement due to the old wood floors lacking a sub-floor.

So now, I understand removal of the tiles is not a huge problem and I will need to get the glue tested for asbestos between the tiles and wood floor before I can think of sanding it off, but have we already been exposed for the 3 years I've been here? I have my laundry in the basement. Store things there. Have spent many, many hours cleaning out the basement. Some of the tiles came up mostly intact , but others crumbled. Never thought about them being asbestos until I started reading about them recently.

Any idea of how to move forward? Damage done? No asbestos disclosure with sale and this was a bad DIY job, so he knew which is no doubt why he covered that room with laminate instead of taking it back to the floor like the rest of the house. Frustrated as the entire ceiling is open to the attic at the moment. Have a new expensive HVAC system. Will that have to be cleaned, too?

Any input most appreciated.

Asbestos in tiles is quite inert, especially if left undisturbed. Sanding is another story, so yes, you're wise to get it tested, but it sounds like you'd be unlikely to have been exposed just from being in the basement, doing laundry, etc.

You could take some sort of swab sample of the dust in the ducting, I suppose, if there's even enough material to test. You'd need to consult with the lab in advance to make sure you'd get what they needed, and in an adequate amount. Most of the labs that test for asbestos commercially are looking at things like your tile and they are trying to tell if it is 1% or more asbestos, because that is regulated differently. You'd probably get a "non detect" result from your HVAC unless you went somewhere very specialized.

I read your question again and I'm not 100% sure I understood the layers of material. What was sanded to make the dust? The wood below the asbestos tiles?
