When water invades your home unexpectedly, the clock starts ticking. Whether it’s from a burst pipe, a faulty appliance, or storm flooding, immediate action is critical to minimize structural damage, prevent mold growth, and reduce repair costs. At First Coast Contracting, we respond 24/7 to water damage emergencies across Jacksonville and St. Augustine, providing professional cleanup, structural drying, and restoration support. That said, there are essential steps every homeowner should know to handle the first critical hours after water damage.

Stop the Water Source and Shut Off Power
If it’s safe to do so, locate the source of the water and stop it. Shut off the main water valve if necessary. For burst pipes or plumbing issues, this is usually straightforward. If the damage comes from storm-related flooding, focus on keeping your family safe rather than trying to control the inflow.
After stopping the water, cut off power to affected areas. Water and electricity don’t mix, and even if everything appears fine visually, soaked walls or wiring can pose serious risks. If you need to walk through standing water to reach the breaker, wait for professional help instead.
Document Everything for Insurance
Before touching anything, take photos and videos of the damage. Capture wide shots of each affected room, plus close-ups of damaged flooring, walls, furniture, and belongings. Open cabinets and drawers to show interior damage. These records are crucial for insurance claims, and digital timestamps help validate the timeline.
Don’t throw anything out unless it’s a clear biohazard. If you must dispose of anything, take detailed photos first. Your insurance adjuster will want a complete picture of the loss, and missing documentation can result in denied or reduced claims.
Extract Standing Water
Use a wet/dry shop vacuum, mops, or towels to begin removing standing water. Avoid using a standard household vacuum, even if it’s rated for wet surfaces. If there’s more than a few gallons of water, or if it’s contaminated (such as from a sewage backup), don’t try to handle it on your own. Professionals have truck-mounted extraction equipment and know how to handle category 2 and 3 water safely.
Remove Rugs, Upholstery, and Soaked Items
Start pulling up rugs and moving furniture out of the affected area. Upholstered items hold moisture, which creates the perfect environment for bacteria and mold. Wood furniture can also warp quickly. Place aluminum foil or wood blocks under furniture legs to prevent further moisture absorption if items must stay in place temporarily.
Be careful when moving waterlogged items—they’re heavier than usual and can cause strain or injury. If an item can’t be salvaged, document its condition before discarding it.
Promote Airflow and Begin Drying
Open windows if the outside humidity is low. Use fans and dehumidifiers to help dry out the space, focusing on corners, baseboards, and walls. The goal is to reduce moisture levels before mold has a chance to develop, which can begin within 24 to 48 hours of water exposure.
Consumer-grade equipment can be helpful for minor incidents, but deeper water damage requires commercial drying tools. Subflooring, insulation, and structural framing can hold onto moisture long after surfaces feel dry. Professionals use thermal imaging and moisture meters to identify hidden saturation areas.
Inspect for Hidden Damage
Water moves fast and doesn’t always stay where you expect it. Check nearby rooms, ceilings below the affected floor, and wall cavities. Pay close attention to drywall, trim, and floors for signs of swelling or discoloration.
Tile may appear unaffected, but water can seep beneath grout lines and cause subfloor rot over time. Laminate and engineered wood flooring often needs to be removed to fully dry underlayment. If you’re unsure about what’s been affected, it’s worth having a professional inspection done.
Watch for Mold in the First 72 Hours
Mold spores are everywhere in the air, but they only activate when conditions are right—and moisture is the trigger. Mold can begin growing within 24 hours and becomes well-established after three days. Watch for musty odors, new stains on walls or ceilings, and fuzzy growth on furniture or drywall.
If mold starts to appear, avoid disturbing it. Scrubbing or spraying mold can release spores and spread the contamination. Professional mold remediation follows containment and removal protocols to ensure safety and prevent future outbreaks.
Contact Your Insurance Provider Promptly
Don’t wait too long to notify your insurance company. Most policies require prompt reporting and may limit your coverage if delays cause further damage. Give them the photos, notes, and receipts you’ve gathered, and keep records of every communication.
Ask about emergency services coverage. Many policies will pay for water extraction, drying, and temporary lodging if your home is uninhabitable. If you’re working with a contractor like First Coast Contracting, we can assist with documentation and help streamline the claims process.
Know What Can Be Salvaged—and What Can’t
Hard surfaces like tile, concrete, and hardwood often survive water exposure if dried properly. Drywall, carpet, particleboard, and insulation are more vulnerable. If water has reached electrical outlets or gotten into HVAC systems, those need to be evaluated by licensed professionals.
Paper documents, books, and photographs can sometimes be saved using specialized freeze-drying techniques. Electronics should be unplugged and air-dried, but never powered back on until evaluated. Contaminated water from sewage backups or storm surges requires stricter disposal rules for soft goods, clothing, and porous materials.
Don’t Wait to Bring in Professionals
A common mistake is underestimating the extent of water damage. Even if your floors look dry and the air feels normal, hidden moisture can continue damaging your home long after the incident. Within days, you might see warped baseboards, musty smells, or mold staining on drywall.
Restoration professionals bring expertise, equipment, and experience. We use industrial dehumidifiers, air movers, and moisture detection tools to make sure the drying process is complete. We also identify and repair structural issues and coordinate with your insurance company to ensure everything is documented properly.
Quick action is critical in any water emergency. The more thorough your response in those first 24 to 48 hours, the better your chances of avoiding serious complications. Whether you’re handling a minor incident or facing major flooding, understanding what to do next helps protect your home and gives you more control in a stressful situation.
