Tile removal is priced by floor area, by how hard the tiles are bonded, and by whether the adhesive bed is coming up with them. The tiles themselves usually lift; the black bitumen underneath is the part that decides the price, because taking it off means mechanical work at floor level and taking it off badly means grinding, which is the one thing that must not happen.
Tiles and bed are two jobs
Lifting the tiles is straightforward where they have already started to release. Removing the adhesive is a separate operation with its own method and its own waste. Some jobs take the tiles and encapsulate the bed under a levelling compound; some take both. Ask which one a quote is for, because the difference is most of the price.
How they come up
Cold and whole, with hand tools, kept damp, and bagged as they go. Not heated, not ground, not sanded. Heat softens bitumen and produces fume; grinding produces exactly the dust the regulations exist to prevent. A quote that mentions a floor grinder for an asbestos backed floor is a quote to make a small problem into a large one.
Covering instead
A sound tiled floor can be overlaid with a floating floor or a levelling compound, leaving the tiles and the bed undisturbed. It is cheaper, quicker and produces no hazardous waste. Record it, because the next person to lift that floor needs to know what is under it, and a floor lifted in ignorance is how the material is met at its worst.
Waste
Tiles are dense and the adhesive comes up with dust and scrapings, so the waste is heavier than the volume suggests and it is charged accordingly. It is double wrapped, labelled and consigned like any other asbestos waste, and the consignment note is part of what you are buying.
Questions people ask about asbestos tile removal
How much does asbestos floor tile removal cost?
It is priced by area, by bond strength and by whether the adhesive is included, so a small kitchen and a whole ground floor are different jobs. Ask whether the bed is in the price.
Is tile removal licensable?
Floor tiles and their bitumen adhesive are normally non-licensed work, sometimes notifiable non-licensed work depending on the method used.
Can the tiles just be covered?
Yes, and it is frequently the better answer where the floor is sound. It has to be recorded so the material is not met unexpectedly later.
