Water damage
Structural drying in St. Louis, MO
Structural drying removes moisture that has soaked into walls, framing, subfloors and cabinets after the visible water is gone. It uses calculated airflow, dehumidification and daily meter readings so materials reach a documented dry standard before anything is closed up.

Combined sewers in older neighborhoods back up into basements during heavy rain. St. Louis's brick homes almost all have basements with floor drains connected to the sewer, which back up during heavy storms.
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.

Structural drying 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.
Why not just use fans?
Fans move air but don't remove moisture from it. Without dehumidification, the water evaporated from your walls stays in the room and soaks back into other materials.
Do walls always have to be cut open?
No. Many clean-water losses dry in place with small access holes. Walls are cut when water is contaminated, insulation is soaked, or readings won't come down.
