Commercial Flood Damage: Protecting Your Business Assets
Last updated October 25, 2026
The short answer
Immediate Steps After Flooding
When floodwater enters your commercial space, safety comes first. Turn off electricity at the main breaker if you can do so without stepping into water. Avoid contact with floodwater, as it may contain contaminants. Evacuate employees and customers, and do not re-enter until local authorities say it is safe. If you feel unwell, see a doctor promptly.
Once safe, begin documenting the damage. Take photos and videos of every affected area, including water levels, damaged inventory, and equipment. Make a written list of what you see. This documentation supports your insurance claim and helps the restoration process. Do not throw away damaged items until your insurance company tells you it is okay.
- Turn off power and gas if safe to do so
- Wear protective clothing and boots
- Document all damage with photos and videos
- List damaged assets and their estimated value
- Move undamaged items to a dry area
- Contact your insurance company right away
Drying Out Your Commercial Space
Floodwater soaks into walls, floors, and furniture, creating conditions for mold and structural decay. The faster you dry the space, the better. Open windows and doors if weather permits, and use fans and dehumidifiers to remove moisture. But be careful: do not run electrical equipment in wet areas. The pros use industrial drying equipment that can handle large spaces efficiently.
In Kirkland, the mild marine climate with wet winters and dry summers means outdoor drying may not always be possible. You may need to rely on mechanical drying. Remove wet carpets and padding, as they are difficult to dry and can harbor mold. If water has soaked into drywall or insulation, you may need to remove and replace those materials after a professional assessment.
Salvaging Equipment and Inventory
Your business assets include computers, machinery, stock, and records. Many items can be saved if dried quickly. Electronics should be dried and cleaned by professionals before reuse. Paper documents can be frozen to stop mold growth, then dried later. For inventory, check with your insurance company about what is covered and what can be discarded.
The pros have specialized techniques for drying and cleaning equipment, from circuit boards to office furniture. They can also help you prioritize which items to save based on value and replaceability. Act quickly, as mold can start growing within 24 to 48 hours in warm conditions. Your insurance policy may cover the cost of professional drying services.
- Do not power on wet electronics until dried and inspected
- Freeze wet paper records to prevent mold
- Separate damaged inventory from salvageable stock
- Clean and disinfect hard surfaces with appropriate solutions
- Keep a log of all items you discard for insurance purposes

Preventing Future Flood Damage

Move electrical outlets and server rooms to higher levels. Seal cracks in foundations and walls. Regular maintenance of your building's drainage system can reduce flood risk.
