Lead Paint Testing · California
What is lead dust wipe testing and why is it important?
Short answer
Dust wipe testing measures the amount of lead dust on floors, window sills, and other surfaces. This is often the most dangerous form of lead exposure because microscopic dust can be easily inhaled or ingested by children.
Even if the paint on your walls is in good condition, friction surfaces like sliding windows can create lead dust over time. ClearPoint Environmental performs dust wipe sampling to ensure your living environment is truly safe. This is also a common requirement for 'clearance' testing after a renovation project is finished. By verifying that lead dust levels are below EPA safety limits, we help ensure that your home is safe for re-occupancy after construction or lead abatement work.
