Restore Pro SD does not diagnose illness and does not test mold. Dark staining after a leak is a moisture problem until a qualified tester says otherwise.
What to do
Stop the water if you can reach a shutoff without standing in water. CDC guidance is not to switch power on or off while standing in water.
EPA guidance is to fix plumbing leaks and other water problems as soon as possible and dry items completely. If sewage or other contaminated water caused the damage, call a professional experienced with that work.
If someone in the house has symptoms they worry about, that is a clinician question, not a Restore Pro SD medical opinion.
Ask the independent professional to find the wet materials behind the stain: drywall paper, pad, or insulation. Restore Pro SD does not sell bleach protocols or clearance packages.
We match you with a licensed independent professional. You contract with them. Call (858) 400-4586. The line takes a recorded message.
