The short answer

Know Your Water Risks

Water can enter a warehouse through roof leaks, burst pipes, overflowing drains, or ground seepage. Each source leaves different damage, so walk your facility and note where water might get in. Check roof seams, pipe joints, and the base of exterior walls for signs of past moisture.

If you live in Kirkland, keep your shutoff valve location written down. A burst pipe can release hundreds of gallons quickly, so knowing how to stop the flow matters. Also, understand your building's drainage system and where gutters and downspouts direct water away from the foundation.

  • Inspect roof flashings and seams for gaps or wear.
  • Look for rust or damp spots on pipes and fittings.
  • Check door seals and dock levelers for gaps.
  • Confirm floor drains are clear of debris.
  • Know the location of the main water shutoff valve.

Store Inventory off the Floor

Even a small leak can ruin cardboard boxes and pallets sitting directly on concrete. Store inventory on pallets, shelving, or racks that keep items at least a few inches above the floor. This simple step buys time during a leak and keeps goods dry longer.

For items that are especially water-sensitive, such as paper products, electronics, or textiles, use sealed plastic bins or shrink wrap. Keep aisles clear so you can move product quickly if water appears. Plan storage so the most valuable items are in the driest, most protected areas of the warehouse.

  • Elevate all cartons and boxes off the floor.
  • Use plastic pallets instead of wood where possible.
  • Wrap sensitive items in waterproof sheeting.
  • Store critical inventory in high, dry racks.
  • Keep a clear path to move product fast.

Act Fast When Water Appears

Time is your biggest enemy during a water event. The longer water sits, the more it soaks into packaging, product, and building materials. As soon as you spot water, shut off the source if you can do so safely, then start moving dry goods away from the affected zone.

Use fans, dehumidifiers, and open doors to encourage air movement, but do not rely on these alone for large or hidden moisture. For extensive water, local water damage pros have industrial drying equipment and moisture meters. They can also detect water trapped in walls, under floors, or in insulation.

Document Everything for Claims

Before you touch anything, take photos and videos of the water, the affected inventory, and the surrounding area. Write down the time you discovered the leak and what you did in response. This record helps your insurance company understand the scope of the loss.

Keep damaged items separate from undamaged stock, and do not throw anything away until your insurer tells you to. Save receipts for any supplies you buy to mitigate the damage, like fans or plastic sheeting. Policies vary, and your insurer decides what is covered.

Drying and Salvage Steps

For items that can be dried, move them to a dry, ventilated space and set up fans or dehumidifiers. Remove wet cardboard and packaging, as it can trap moisture and promote mold. For building materials like drywall and insulation, water can soak deep, so drying may take days.

If water has touched electrical equipment, do not turn it on until a qualified electrician checks it. For contaminated water, such as from a sewer backup, treat everything as a biohazard and call the pros. They have the training and equipment to handle hazardous cleanup safely.

  • Separate wet from dry inventory immediately.
  • Remove soaked cardboard and packaging.
  • Run dehumidifiers and fans for days, not hours.
  • Do not power on wet electronics until checked.
  • Call pros for contaminated or deep water damage.

Frequently asked questions

How long does it take to dry a warehouse after water damage?

Drying time depends on the extent of water, the materials affected, and the drying equipment used. Small surface leaks may dry in a few days, while water in walls or under floors can take a week or more. The pros use industrial equipment to speed the process.

Can I salvage wet cardboard boxes and paper products?

Generally, no. Cardboard and paper products soak up water quickly and become weak, moldy, and unsalvageable. It is usually safer to discard them and focus on saving items that are less porous, like plastics or metals. Your insurance company can help determine what is worth replacing.

What should I do if water touches electrical equipment?

Turn off power to the affected area at the breaker, if safe to do so, and do not touch wet equipment. Do not turn anything on until a qualified electrician inspects it. Water can cause short circuits and fire hazards, so professional assessment is necessary before reuse.
