The source of the water matters
A clean-water plumbing leak and a sewage backup are different cleanup situations. Describe the source as accurately as possible when requesting help.
Porous materials may be affected
Flooring, drywall, insulation, furnishings, and other absorbent materials can respond differently to sewage exposure. The actual conditions determine the work required.
Call before disturbing the area
If the contamination is extensive or you are unsure how to proceed, avoid unnecessary contact and call to discuss the property before attempting a large cleanup.
