In the middle of a remodel, and I've discovered there really is hardwood under the ugly vinyl in my kitchen. Unfortunately, there are 4 layers of flooring: vinyl, vinyl, asbestos tile, and hardood.

I'm pondering how to proceed. I'm considering professional abatement, but having trouble getting cost estimates (it's only about 100 square feet, and the building is unoccupied), so if anyone has guesses I'm interested in them.

I'm likely to do the work myself to save money and time, if I can work out a safe way to do it. I'm currently considering two options:

1) Take a circular saw to the floor, cutting through all 4 layers, and pick it up in foot-square chunks.

2) Take the floor up in layers: Remove the vinyl, then pry up the asbestos tile trying to keep it intact, then cut up the hardwood (which is basically ruined by the mastic) and remove that.

In either case I would keep the area and air wet, use a mask, and do a wet clean afterwards.

Option 1 obvious will create some dust, but I wonder if the overall exposure is lower than option 2, which is slower and will probably break up more tile, etc, etc.

What do people think? Are there other approaches I should consider?
