The first 24 hours after a Houston flood determine whether your claim pays in full or gets contested for "failure to mitigate." This timeline reflects what our crews actually do on Cat 2 and Cat 3 emergency response calls, distilled into actionable steps you can take immediately.
Cut Power, Cut Water, Evacuate if Necessary
Throw the main breaker before stepping into standing water. Shut off the main water supply if the source is internal. Move family/pets to dry, unaffected floor or evacuate if water level is rising or sewage-contaminated.
Photograph and Video Everything Before Cleanup
Wide shots of every affected room from doorway. Close-ups of high-water lines on walls. Photo every damaged item with serial numbers when possible. Video walkthrough with date/time stamp. Save to cloud storage immediately.
Contact a Houston Water Damage Restoration Company
Call a Houston IICRC-certified restoration company before insurance. They'll help with scope documentation that protects your claim. Mold begins growing at 24-72 hours; speed of mitigation directly affects coverage and cost.
File Insurance Claim with Documentation
Open claim with carrier (or NFIP if flood policy). Provide initial photo/video documentation. Get claim number and adjuster contact. Texas Insurance Code 542A requires carrier acknowledgment within 15 days.
Aggressive Water Extraction and Drying Begins
Restoration crew begins extraction, removes wet porous materials (drywall, insulation, carpet pad for Cat 3), sets air movers and dehumidifiers. Insurance requires reasonable mitigation; failure to act compounds damage and may reduce payout.
Structural Drying with Daily Moisture Monitoring
IICRC S500 standard drying time. Moisture readings logged daily. Houston humidity often extends drying 1-3 days beyond standard. Adjuster typically inspects mid-cycle.
Reconstruction: Drywall, Flooring, Paint, Trim
Materials installed back to pre-loss condition per Xactimate scope. Permits pulled if structural. Final walk-through with insurance adjuster signs off. Workmanship warranty begins.
Phase 1: Safety (First 60 Minutes)
Water and electricity are lethal. Before stepping into any standing water, throw the main breaker at your electrical panel. If your panel is in the flooded area, call the power company to disconnect at the meter. Natural gas leaks are common after flooding — smell for gas and avoid using flames until cleared.
If the flooding comes from a burst supply line, shut off the main water valve (usually a knob in your front yard near the street, or a lever just inside the garage). If from a sewage line backup, do NOT enter the contaminated area without PPE; Cat 3 sewage carries E. coli, hepatitis, and other pathogens.
Phase 2: Document Before You Clean (1-4 Hours)
This is the single most important phase for protecting your insurance claim. Take wide-angle photos of every affected room from the doorway. Capture the high-water line on every wall — we mark it with blue painter's tape on Cat 3 jobs. Video walkthroughs with date/time stamps are admissible in supplement disputes.
Phase 3: Call a Houston Restoration Company (4-8 Hours)
Contact a Houston IICRC-certified restoration company BEFORE finalizing your insurance claim. A restoration company documents the scope of loss using Xactimate (the same software your adjuster uses), creating an apples-to-apples basis for negotiation. Cheap or inexperienced contractors often under-document, leaving thousands of dollars uncollected.
Phase 4: File the Insurance Claim (8-24 Hours)
Open your claim with your carrier as soon as you have initial documentation. For NFIP flood policies, you have 60 days from the date of loss to file a Proof of Loss — do not delay. Provide your claim number to your restoration company; they handle direct adjuster communication from here.
Phase 5: Aggressive Mitigation (24-72 Hours)
Mold growth begins at 24-72 hours in Houston's 70°F+ ambient temperatures. Insurance policies require "reasonable mitigation" — failing to dry promptly allows compounding damage that may not be covered. RCS crews mobilize industrial-grade truck-mounted extractors, LGR dehumidifiers, and high-velocity air movers within hours of dispatch.
Phase 6: Structural Drying (3-10 Days)
IICRC S500 standard drying time is 3-5 days for typical residential structures. Houston humidity often extends this. Daily moisture readings document progress for insurance. Adjuster inspections typically happen mid-cycle.
Phase 7: Reconstruction (1-12 Weeks)
Drywall, insulation, baseboards, flooring, paint, and trim are restored per the approved Xactimate scope. Permits are pulled for structural work. Final walk-through with the adjuster closes the claim. The workmanship warranty period begins at completion.
