Sewage backup cleanup questions
Do I need a permit for repairs in Gaithersburg?
Cleanup and drying don't. Structural, plumbing and electrical repairs need permits from the City of Gaithersburg Permits and Inspections division.
Who pays for a townhome leak in Gaithersburg?
It depends on the source and the HOA documents. Document the damage and notify your neighbor, HOA and insurer quickly.
Does homeowners insurance cover sewage backup?
Often only with a water or sewer backup endorsement, which most insurers offer as an add-on. Check your declarations page.
Is sewage cleanup dangerous?
Yes. Sewage contains bacteria, viruses and parasites. Professional crews use protective equipment and disinfectants for this reason.
