What to Do After a Flood: First 24 Hours Checklist

Homeowner documenting flood damage

The first 24 hours after water enters your home are important for protecting people and limiting additional property damage. A broken pipe, overflowing fixture, appliance leak, heavy rain, basement water intrusion, or another water event can affect flooring, drywall, cabinets, belongings, and materials that are difficult to see.

The first priority is safety. After that, focus on stopping or controlling the water source when it can be done safely, documenting visible damage, protecting unaffected areas, and determining whether professional water mitigation is appropriate.

This guide provides general first-24-hours flood and water-damage guidance for Washington homeowners, including information related to Water Damage Restoration and Storm & Flood Damage Restoration. Washington Restorer’s confirmed services include water mitigation, mitigation, restoration repairs, reconstruction, free inspections, and claim assistance within Pierce County, Thurston County, South King County, and Kitsap County.

1. Make Safety the First Priority

Before entering a flooded area, consider whether electrical, structural, or contamination hazards may be present.

Standing water can become dangerous when it reaches outlets, appliances, wiring, extension cords, or other electrical equipment.

Do not walk through standing water to reach an electrical panel or unplug equipment.

If the affected area appears unsafe, keep people and pets away and contact an appropriate qualified professional before entering.

2. Identify Where the Water Is Coming From

Once the area can be approached safely, try to determine the source of the water.

The cause may be obvious, such as a leaking pipe or overflowing fixture. In other cases, water may be entering through a roof, basement, window, drainage area, or another part of the property.

Different causes may require different providers.

A plumbing issue may require a plumber. A roof leak may require a roofing professional. Drainage, foundation, electrical, or other specialty concerns may need their own qualified provider.

Washington Restorer’s approved restoration work should not be interpreted as plumbing, roofing, drainage, foundation, or electrical repair.

3. Stop the Water When It Is Safe to Do So

If the event involves a plumbing supply line or fixture, shutting off the water may help reduce additional damage.

Homeowners should know where the main water shutoff and common fixture shutoffs are located before an emergency happens.

Do not attempt to reach a valve if doing so requires entering unsafe standing water or an area where electrical hazards may exist.

If the source cannot be controlled safely, contact the appropriate professional.

4. Consider Whether the Water May Be Contaminated

Not every flood involves the same water conditions.

Water from a broken supply line is different from wastewater entering through a sewer or drain backup.

If sewage or visibly contaminated wastewater is present, avoid unnecessary contact and keep children and pets away from the area.

An appropriate provider should address contamination concerns before normal water-related restoration proceeds.

Sewage extraction, biohazard cleanup, Category 3 cleanup, sanitizing, and sewage-specific decontamination are not confirmed Washington Restorer services.

5. Document Visible Property Damage

When conditions are safe, take photos or video of the affected areas before making major changes.

Document the condition of rooms, flooring, drywall, cabinets, belongings, and any visible water staining.

You do not need to delay urgent safety measures in order to take photographs. Documentation should only be done when it is safe and practical.

Along with photos, make basic notes about when the water was noticed, where it appeared to come from, and which areas were affected.

Avoid guessing about the cause if it has not been confirmed.

6. Limit Water From Spreading Into Dry Areas

When possible, reduce unnecessary movement between wet and dry parts of the property.

Repeatedly walking through water and then into unaffected rooms can spread moisture and, depending on the source, contamination.

Move unaffected belongings away from the edge of the water when it is safe to do so.

Items that are already damaged can be documented before being moved whenever practical.

7. Do Not Judge the Damage by the Visible Water Alone

Standing water may be the most noticeable part of a flood, but it does not always show the full extent of the property damage.

Water can move beneath flooring, behind baseboards, into drywall, around cabinets, and into other concealed areas.

Even after the visible water is gone, moisture may remain within subflooring, lower wall materials, wood components, carpet padding, insulation, or cabinet bases.

A professional water-damage evaluation may be appropriate when the extent of the moisture is unclear.

8. Check Drywall, Walls, and Baseboards

Drywall and trim can absorb water after relatively short periods of exposure.

Possible signs of water-related damage include swelling, staining, softness, bubbling paint, or separation around the lower wall.

Visible staining may not show exactly how far moisture traveled.

Avoid painting or replacing trim over affected areas before the remaining moisture has been evaluated.

9. Pay Attention to Flooring

Flooring can conceal moisture beneath the finished surface.

Carpet may hold water in the padding. Laminate can swell or separate. Wood may warp, cup, or change shape. Water may also move beneath vinyl or tile assemblies.

Watch for lifting, buckling, separation, discoloration, or changes in how the floor feels underfoot.

The floor may look dry while water remains beneath it.

10. Check Cabinets and Built-In Materials

Water from bathrooms, kitchens, laundry rooms, basements, and utility areas can travel beneath cabinets or into areas that are difficult to see.

Look for swelling, staining, separation, or persistent dampness around cabinet bases and nearby wall materials.

Whether a cabinet or built-in material can be retained depends on its condition and the extent of the water exposure.

11. Avoid Permanent Repairs During the First Day

The first 24 hours should focus on safety, source control, documentation, and water-related damage evaluation.

It is usually too early to repaint walls, install new flooring, or cover damaged areas if the underlying materials may still be wet.

Permanent repairs should follow mitigation and evaluation rather than hide unresolved moisture.

12. Use Household Equipment Carefully

Fans or other household drying equipment may help with minor surface moisture in some situations, but they do not confirm that hidden areas are dry.

Do not operate electrical equipment where standing water or electrical hazards are present.

If contaminated wastewater is involved, ordinary household drying methods may also be inappropriate until the contamination has been addressed by an appropriate provider.

13. Think About Mold Prevention as Moisture Management

A water event does not automatically mean mold will develop.

The practical priority is to reduce the amount of time building materials remain wet.

Watch for persistent dampness, musty odors, soft drywall, warped flooring, or recurring moisture after the initial event.

Mold-specific services should be handled separately by an appropriate provider when needed.

Mold inspection, mold testing, mold remediation, and clearance testing are not confirmed Washington Restorer services.

14. Contact Your Insurance Provider When Appropriate

Water-damage coverage varies according to the cause of the loss, policy terms, exclusions, endorsements, and the insurer’s determination.

When appropriate, contact your insurance provider and provide factual information about what happened.

Photos, videos, and written notes may help document the condition of the property.

Washington Restorer provides claim assistance for approved restoration work.

Claim assistance may help with restoration-related documentation and communication, but it does not guarantee insurance coverage, claim approval, reimbursement, payment, or a particular settlement.

The First Few Hours vs. the Rest of the First Day

During the first several hours, concentrate on immediate safety and controlling the source.

Keep occupants away from unsafe areas, stop additional water when possible, and contact the appropriate provider when the source requires specialized repair.

During the rest of the first day, document the damage, identify which building materials were affected, and determine whether professional water mitigation may be necessary.

The goal is not to complete the entire restoration in 24 hours. The goal is to reduce avoidable additional damage and establish the appropriate next steps.

What If the Flood Is in the Basement?

Basements can hold significant amounts of water because they are among the lowest areas of a property.

Check flooring, lower wall materials, baseboards, storage areas, utility spaces, and other accessible surfaces.

Do not enter standing basement water when electrical equipment may be affected.

Basement flooding can result from plumbing problems, heavy rain, sump system issues, drainage conditions, or sewer backups. The underlying source should be identified by the appropriate provider.

Washington Restorer can address approved water-related restoration needs after the relevant source and any contamination concerns have been appropriately handled.

What If Heavy Rain Caused the Water Damage?

Rainwater may enter through roofs, windows, basements, drainage areas, or other openings.

When conditions are safe, look for signs that may help identify where water entered the property.

Roof, drainage, window, foundation, or other specialty repairs should be handled by the appropriate qualified professional.

Washington Restorer’s role remains focused on approved water mitigation and restoration services.

Storm cleanup, flood cleanup, emergency board-up, roof tarping, drainage repair, and other storm-specific services are not confirmed Washington Restorer offerings.

When Should Water Damage Be Professionally Evaluated?

Professional evaluation may be appropriate when water has affected drywall, flooring, cabinets, insulation, multiple rooms, or concealed building materials.

It may also be appropriate when water remains after the source is stopped, flooring begins lifting or warping, drywall becomes soft or swollen, lower levels have been affected, or the full extent of the moisture is unclear.

Washington Restorer provides approved water mitigation services for qualifying water-related property damage within its confirmed service areas.
