You’re dealing with
Signs you need water damage or
mold remediation in St. Louis
A musty smell that won’t go away.
Air-quality testing tells you whether it’s surface mold, hidden mold inside a wall cavity, or just damp drywall. Independent findings inform our remediation scope, and sometimes the test means we tear out less than you feared.
A ceiling stain that keeps coming back.
Patch-and-paint never fixes a wet ceiling. Water always finds the same path. We trace it to source, dry the framing, and document everything for your insurer.
An insurance carrier dragging its feet.
Most kicked-back claims fail because the file is missing scope detail, drying logs, or photos. We write the file your carrier wants the first time, Xactimate-aligned, with adjuster comms when you authorize.

Common questions
Water damage restoration questions in St. Louis, MO
How does water damage restoration work in St. Louis?
It starts with a call to (314) 947-3419 so we can confirm whether water is still entering and dispatch a crew. On site we find the source, map wet materials with moisture readings, extract standing water where access is safe, and set drying equipment based on the measured area. We monitor readings until they support completion and keep dated photos and notes for the insurance file. Across St. Louis and the Metro East, the source can be a supply line, a storm, groundwater or a sewer backup, and each one needs a different response.
Who at Gateway is IICRC certified?
Owner Jake Lusby holds IICRC certifications in Water Restoration Technician (WRT) and Applied Structural Drying (ASD), the IICRC courses that cover water damage mitigation and drying a structure to verified readings. Ask who will lead your job and which certifications they hold.
How long does water damage restoration take?
Drying time depends on the affected materials, how far moisture traveled, contamination and access. Ask for a project-specific estimate after the first inspection, with updates as the readings change. Confirm whether reconstruction is part of the written scope or handled separately.
How much does water damage restoration cost in St. Louis?
Cost depends on the wet area, the materials involved, the water source and contamination, and whether reconstruction is included. Request a written scope and estimate before work begins, and confirm any assessment charges and what you may owe beyond your deductible.
Does homeowners insurance cover water damage in St. Louis?
Coverage depends on the cause of loss, your policy terms, endorsements and exclusions. A sudden supply-line break, long-term seepage and a sewer backup can be treated differently. Gateway documents the observed damage with photos, moisture readings and line items; your insurer decides coverage.
Can water damage turn into mold?
Materials that stay wet can support mold growth, which is why drying is checked with moisture readings rather than by touch. If growth is suspected, Gateway can sample it for analysis by an independent laboratory and handles moisture correction and remediation.
How do I choose a water damage restoration company?
Ask for a written scope before work starts, moisture readings that show why each material is being removed, and dated documentation you can give your insurer. You keep the right to choose your own restoration contractor, whoever your carrier suggests.
