Asbestos floor tiles that are intact and sealed are generally low risk, because the fibres are locked into the tile. The risk comes when they are broken, sanded, drilled or scraped, which can release fibres into the air. Never sand, grind or power-scrape old tiles or the black adhesive underneath.
If you are renovating, replacing flooring or the tiles are cracked and lifting, have them tested or removed by a trained team first. We can also collect asbestos waste if tiles have already been lifted.
