How Do You Restore Natural Stone Floors After Flooding?

Act quickly but carefully. Standing water can seep into stone and the subfloor beneath, causing long-term damage. Remove water with a wet-dry vacuum or mop, but avoid pushing water into grout lines. Open windows and use fans to promote airflow, but do not use heat, as rapid drying can crack stone.

If the floodwater is contaminated, treat it as a biohazard. Wear gloves, boots, and a mask. Discard porous items like rugs or cardboard that touched the water. For safety, turn off electricity in the affected area before stepping in. If you feel unwell, see a doctor.

Proper drying is critical to prevent mold and mildew, which can grow on stone and grout. Use dehumidifiers and fans to lower humidity. Keep the area ventilated for several days. Check for any remaining moisture with a moisture meter if you have one.

If mold appears on grout or stone, clean it with a hydrogen peroxide solution (test first). For extensive mold, a mold professional should handle it. If you live in Bellingham, remember that the mild marine climate can slow drying, so be patient and thorough.

Some damage is beyond DIY repair. If the stone has deep cracks, major staining, or if the subfloor is compromised, local water damage pros can assess the situation. They have industrial drying equipment and specialized tools for stone restoration. They can also help with water damage inspection.

Before any major work, check your insurance policy. Policies vary, and your insurer decides what is covered. Document the damage with photos and keep receipts for any supplies. For complex cases, the pros can guide you on the right course of action, but outcomes depend on the specific situation.
