The National Oceanic and Atmospheric Administration defines the Atlantic hurricane season as June 1 through November 30, with peak activity historically concentrated in August and September. For homes in Corpus Christi, Portland, Rockport, and the surrounding Coastal Bend, this period represents the highest annual risk of water intrusion and subsequent mold growth.
Pre-Storm Inspection Checklist
Before a named storm approaches, a focused inspection of known water entry points can prevent significant interior damage.
Roof and flashing: Check for missing or damaged shingles, lifted flashing around chimneys and vents, and gaps in ridge caps. According to the Insurance Institute for Business & Home Safety, roof damage is the leading cause of water intrusion during hurricanes.
Windows and doors: Verify that weatherstripping is intact, caulking around frames has not cracked or separated, and garage door seals create a proper barrier. Wind-driven rain can penetrate surprisingly small gaps.
Gutters and downspouts: Clear all debris. Water that cannot flow through gutters overflows against siding and foundation walls, creating both immediate flooding and long-term moisture accumulation.
Crawl space and foundation: Ensure foundation vents are clear and that the ground around the home slopes away from the structure at a minimum grade of 5 percent for the first 10 feet. Poor drainage is one of the most common preventable causes of post-storm mold.
Emergency Power for Sump Pumps and Dehumidifiers
If your home has a sump pump, battery backup or generator power is essential. Once floodwater enters, the pump's job is to move it out faster than it accumulates. Without power, the pump is useless. Portable dehumidifiers also require electricity, and they are critical for reducing humidity in enclosed spaces after water intrusion.
Interior Preparation
Move valuable items and electronics off the floor, particularly in ground-level rooms and garages. Roll up area rugs and move them to elevated surfaces. Remove items from closets and storage rooms that back onto exterior walls, as these are common water entry points during wind-driven rain events.
Documentation for Insurance
Before storm season, photograph the pre-storm condition of your home's interior and exterior. Document the condition of roofing, siding, windows, and any existing signs of moisture or prior repairs. If damage occurs, these photos establish the baseline for insurance claims.
The First 24 Hours After Water Entry
If water enters your home during a storm, the response in the first 24 hours determines whether the event becomes a manageable repair or a major mold remediation. As covered in IICRC S500 guidelines, professional water extraction should begin as soon as conditions are safe. Simply pumping water out is not enough — structural materials must be dried to specific moisture content thresholds using dehumidification and air movement.
The Most Common Post-Storm Mistake
Homeowners who experience minor flooding often assume that because the water is gone, the problem is solved. In reality, moisture that penetrates wall cavities, insulation, and subflooring remains trapped for weeks without professional drying. By the time mold becomes visible, the remediation scope has expanded dramatically.
When to Call a Professional
If water has contacted drywall, insulation, flooring, or structural framing, professional assessment is warranted regardless of how quickly the standing water was removed. Moisture meters can detect hidden wet areas that visual inspection misses. In the Coastal Bend's high-humidity environment, hidden moisture does not dry on its own.
Hurricane preparation is not just about boarding windows. It is about understanding how water behaves in your specific home and taking steps to keep it out — or remove it quickly when it gets in.
