Brick homes with basements dominate, many with clay sewer laterals and floor drains connected to combined sewers. South City's brick homes and flats from the late 1800s to the 1930s have deep basements, original clay laterals and limestone or brick foundations that seep during heavy rain. Many are owner-occupied two-family flats, so leaks between floors are common.
Licensing in Missouri: Missouri doesn't license general contractors statewide. Cities and counties, including St. Louis and Kansas City, license contractors locally.

Mold Removal questions
Is sewer backup covered by insurance in St. Louis?
Usually only with a sewer or water backup endorsement.
Do I need a permit for repairs in St. Louis?
Structural, plumbing and electrical repairs need permits from the City of St. Louis Building Division.
Is bleach enough to kill mold?
Not on porous materials like drywall and wood. Bleach mostly lightens the surface. Porous materials with growth are usually removed, and the moisture source has to be fixed.
Do I need mold testing?
Not always. If mold is visible, the priority is removing it and fixing the moisture. Testing helps when you smell mold but can't find it, or when clearance is required.
