The area was properly contained, cleaned, treated, and tested before they declared it safe. I can't say enough good things about how they handled it."
"The team at COS Water Damage Restoration saved our hardwood floors. I was told by two other contractors that the floors would need to be torn out and replaced after our basement flooded.
