Basement flooding
in St. Louis.

Basement restoration company for St. Louis flood cleanup.

Basement flood cleanup should address the actual water source, contamination concerns and affected materials. Discuss safe extraction, drying, moisture documentation and any necessary source repair with the restoration team. Cleanup documentation does not guarantee mold prevention or a claim outcome.

Gateway Water & Mold handles basement flood cleanup for sump pump failures, sewer backups, storm-water overwhelm, foundation seepage, appliance leaks, and supply-line breaks across the St. Louis metro. We start with source-of-loss triage, then build the cleanup plan around the water category, affected materials, and what your insurance carrier will need to see.

If water is coming up from the basement floor

Water at a floor drain, crack or slab warrants safe assessment of the actual source and contamination concerns. Discuss necessary source repair and an appropriate extraction and drying plan with qualified professionals; the visible entry point alone does not determine the cause.

What Gateway documents before the rebuild

• Source-of-loss notes: sump, sewer, storm, seepage, appliance, or plumbing leak.
• Moisture readings for walls, framing, flooring, trim, and basement contents when relevant.
• Photos of standing water, affected materials, demo areas, equipment placement, and drying progress.
• Water category and contamination notes, especially when sewer backup or drain water is involved.
• Drying logs and rebuild recommendations for the adjuster, homeowner, or property manager.

If your basement is wet now, contact Gateway to discuss safe assessment before disturbing affected materials. Report the observed water entry and any known source. The restoration assessment informs cleanup and documentation; the insurer determines coverage under the actual policy.
