Work done during a recent remodel generated lots of concrete dust in my mother's home. The house has a concrete slab foundation. New vinyl wood flooring was installed, and the installers had to grind down uneven spots on the concrete slab during installation. The concrete dust travelled through much of the house, including new carpet that had been installed just prior to the grinding, and the dust is also on the walls and surfaces throughout the house. I believe the workers had some sort of dust-collection device on the grinder, although the dust was still significant. She didn't realize that the grinding work was going to take place, nor the extent of the dust and its possible health impacts.
My mother is concerned about her safety, given that components in concrete dust can be carcinogenic. She was able to vacuum thoroughly with vacuum with a hepa filter several times. The flooring company that did the work was contacted and the owner said the carpet should be clean and safe now (although they of course may be biased).
How big of a concern is this type of situation? Is there an efficient and effective way to clean the walls and other home surfaces? Are there any other considerations relevant to mitigating concrete dust?
