A burst pipe at 2 AM, a roof leak during a thunderstorm, or standing water from a flash flood can cause thousands of dollars in damage before you even arrive on site. What you do in the first 24 to 48 hours after a water event determines whether the situation stays manageable or escalates into mold remediation, structural repairs, and prolonged business disruption.
The first two hours: stop the source and document everything
If the water source is controllable, shut it off immediately. For pipe bursts, that means closing the nearest shutoff valve or the building's main water supply. For roof leaks during active rain, focus on containing the water with tarps, buckets, or barriers to protect equipment and inventory while the storm passes.
Before you move anything, photograph the affected areas thoroughly. Insurance claims depend on documentation, and a few minutes of photos and video at this stage can save weeks of dispute later. Capture the extent of standing water, affected walls and ceilings, damaged equipment, and any visible water stains that indicate the path of flow.
If electrical panels, outlets, or wiring are in or near the water, do not enter the area until the power has been shut off to that section of the building. Water and electricity create a life-threatening combination.
Hours 2 through 12: extract water and begin drying
Standing water must be removed as quickly as possible. Every hour that water sits on carpet, drywall, or wood framing increases the likelihood of permanent damage. Wet vacuums and submersible pumps handle the bulk extraction. Once standing water is removed, focus shifts to moisture in materials. Carpet padding absorbs enormous amounts of water and often cannot be saved. Drywall wicks moisture upward, so water that appears to affect only the floor may have already traveled 12 to 18 inches up the wall.
Air movers and dehumidifiers should be placed immediately. The goal is to reduce ambient humidity below 60% and create constant airflow across all wet surfaces. Opening windows helps only if outdoor humidity is lower than indoor humidity, which is rarely the case in North Texas during warmer months.
Hours 12 through 48: monitor, assess, and prevent mold
Mold can begin to colonize damp materials within 24 to 48 hours. That timeline is not negotiable. Materials that cannot be dried to their pre-loss moisture levels within that window should be removed. This frequently includes carpet padding, ceiling tiles, cardboard storage boxes, and sections of drywall.
Use a moisture meter to check walls, floors, and subfloor materials during this period. Surface dryness is not a reliable indicator. Materials can feel dry to the touch while retaining dangerous levels of internal moisture. Monitor readings over multiple check-ins rather than relying on a single measurement.
Antimicrobial treatments applied to structural materials during this phase can inhibit mold growth while drying continues. These should be commercial-grade products applied according to manufacturer guidelines, not household cleaners.
How Delta supports you during water events
Delta Janitorial Systems is not a restoration company, and we will always recommend a licensed restoration specialist for significant water damage. However, our team plays an important role in the response. For existing clients, we can mobilize quickly to assist with initial water extraction, protect unaffected areas of the building, and adjust cleaning schedules around the disruption. Our 24/7 customer support line means you can reach us when the event happens, not the next business day.
We also help with the recovery phase. Once restoration is complete, our team handles the deep cleaning needed to bring the facility back to occupancy standards: sanitizing surfaces, extracting residual moisture from carpets, and addressing dust and debris left behind by construction crews. Over 50 years of serving DFW facilities means we have seen every type of water event and we know how to help facility managers get their buildings operational again. Call us at (972) 261-9800 if you need support during or after a water emergency.
