What's the First Thing to Do After a Disaster?
Last updated October 31, 2026
The short answer
Safety First
Your first priority after any disaster is safety. If you have standing water, avoid walking through it, especially if it might be contaminated. Turn off the main water valve to stop further flooding, and if water is near electrical outlets or appliances, shut off the power at the breaker if you can do so safely.
Check for structural hazards like sagging ceilings or cracked walls. If you smell gas or suspect a leak, leave the property and contact the gas utility from a safe distance. See a doctor if you feel unwell after exposure to floodwater or debris.
Document Everything
Once you are safe, take photos and videos of all damage before you move anything. Capture wide shots of each room and close-ups of affected areas, including water lines on walls, soaked carpets, and damaged belongings. This visual record helps your insurance company understand the scope of the loss.
Make a written list of damaged items, noting their approximate age and value. Keep receipts for any emergency purchases like fans or dehumidifiers. Policies vary, and your insurer decides what is covered, so thorough documentation is a sensible tool.
- Photograph water levels and stains
- Record serial numbers of appliances
- Note the date and time of the disaster
- Save samples of damaged materials
- List any immediate safety hazards
Stop the Water
If the disaster involves a burst pipe or an overflowing appliance, shut off the main water valve right away. Locate the valve before an emergency so you can act quickly. In Mesa, keep the shutoff valve location written down near your water heater or on your phone.
For roof leaks or flooding from outside, move valuables to higher floors or dry areas. Use towels or buckets to contain small leaks, but do not risk injury trying to stop large flows. Your immediate goal is to limit further water intrusion.
Call the Pros
After you have secured the site and documented the damage, contact local water damage pros. They can assess the extent of the water intrusion and recommend the right cleanup steps. Acting quickly helps reduce the chance of mold growth and structural decay.
The pros typically use specialized equipment to extract water, dry the space, and sanitize affected surfaces. They will also advise on what can be salvaged and what must be removed. Their work usually involves a thorough inspection to guide the restoration process.
- Ask about drying equipment
- Inquire about mold prevention
- Check what materials can be saved
- Discuss the cleanup sequence
- Request a written assessment
Prevent Further Damage
While you wait for the pros, take simple steps to prevent additional harm. Move furniture away from wet walls, remove rugs from soaked floors, and use fans to increase air circulation if it is safe. Prop up wet cushions and mattresses to help them dry.
Do not attempt major repairs yourself, as improper drying can lead to hidden mold. Avoid turning on heating systems if they might circulate moisture. Your focus should be on temporary measures that do not put you at risk or worsen the situation.

How soon should I call the pros after water damage?
You should contact the pros as soon as you have secured the area and documented the damage. Quick action helps minimize mold growth and structural issues. Even a few hours can matter, so do not delay once you are safe.
Can I clean up the water myself?
Small spills you can handle, but significant flooding usually requires professional equipment. The pros have industrial dryers, dehumidifiers, and sanitizers that are not available to most homeowners. Attempting a large cleanup yourself can lead to incomplete drying and hidden damage.
What should I do with wet belongings?
Move valuable items to a dry area if you can do so safely. Do not throw anything away until you have documented it for your insurance records. Some items like photographs or documents may be salvageable with careful drying, but porous materials like mattresses often need replacement.
