What Makes St. Louis Different
St. Louis sits where the Missouri and Mississippi rivers meet, and the Meramec and smaller creeks run through the suburbs. Rivers rise in wet springs, and creeks can flood low neighborhoods fast in heavy thunderstorms. Floodwater from outside is always contaminated, and a standard homeowners policy does not cover it.
Summers are hot and humid, and spring brings severe storms, hail and tornadoes. Wet drywall and carpet pad can grow mold within 24 to 48 hours, so start drying the same day. Winters bring cold snaps and ice that freeze pipes in exterior walls and crawlspaces.
The city is known for old brick homes with deep basements, and many were built long before 1978. Lead paint is common in older homes, so avoid dry sanding and scraping. Old pipe wrap, floor tile and plaster may contain asbestos. Heavy rain can back sewers up into basements, so a backwater valve and a sump pump with a battery backup prevent a lot of damage.

Checking a License in St. Louis
Missouri does not license general contractors at the state level, and licensing is handled by the city and county. Ask the City of St. Louis, St. Louis County or your own town what license the job needs and check it there. On the Illinois side, roofing contractors are licensed by the state, and other contractor licensing is handled locally, so check with your city or county. Neither state has a separate mold license, so ask whether the technicians hold industry certification in water damage and mold remediation, and ask for proof of liability and workers compensation insurance.
