What to Do in the First 24 Hours After Water Damage

Water damage is a time-sensitive emergency. Every hour that passes without professional intervention allows water to penetrate deeper into structural materials, spread to new areas, and create conditions for mold growth. In Atlanta's warm, humid climate, mold can begin growing in as little as 24 hours — making fast action absolutely critical.

This guide walks you through exactly what to do — and what to avoid — in the first 24 hours after discovering water damage in your Atlanta home or business.

Step 1: Ensure Safety First (0–15 Minutes)

Before doing anything else, assess the safety of the situation. Water and electricity are a deadly combination. If there is any possibility that standing water is in contact with electrical outlets, appliances, or wiring, do not enter the affected area. Turn off the electricity to the affected area at your circuit breaker — but only if you can do so without entering the water.

If the water damage is from a burst pipe or other supply line, locate your main water shutoff valve and turn it off immediately to stop the flow of water. In most Atlanta homes, the main shutoff is located near the water meter, typically in the basement, crawl space, or on an exterior wall.

If there is any structural damage — sagging ceilings, buckled floors, or visible foundation issues — do not enter the affected area until it has been assessed by a professional.

Step 2: Call a Professional Water Damage Restoration Company (15–30 Minutes)

This is the single most important step. Call a certified water damage restoration company immediately — do not wait to see if the water recedes or if things dry on their own. Professional intervention in the first few hours dramatically reduces the total damage and cost of restoration.

When you call, provide as much information as possible: the source of the water (if known), the approximate area affected, whether there is standing water, and whether there are any safety concerns. A reputable company will dispatch a team immediately and provide an estimated arrival time.

Step 3: Document the Damage (30–60 Minutes)

While waiting for the restoration team to arrive, document the damage thoroughly with photos and video. This documentation is essential for your insurance claim and will help the restoration team understand the full scope of damage before they arrive.

Photograph and video every affected area from multiple angles. Document visible water levels, damaged materials, and any personal property that has been affected. Note the time and date of each photo. If you can safely do so, take photos of the source of the water damage — a burst pipe, failed appliance, or damaged roof area.

Do not discard any damaged items before your insurance adjuster has had a chance to see them. Create a written inventory of damaged personal property, including estimated values.

Step 4: Protect Valuables and Prevent Further Damage (1–3 Hours)

If it is safe to enter the affected area, move valuables, electronics, important documents, and irreplaceable items out of the water's path. Place aluminum foil under furniture legs to prevent staining on wet carpet. Remove area rugs from wet hard floors — rugs left on wet hardwood can cause permanent staining and damage.

Do not use your home's HVAC system or ceiling fans in an attempt to dry the space. In a water damage situation, running the HVAC can spread contaminated air throughout the home and actually worsen the situation. Leave the drying to the professionals.

If the water damage is from a roof leak or storm damage, place buckets to catch dripping water and cover the damaged area with a tarp if you can do so safely. This prevents additional water from entering while repairs are arranged.

Step 5: Contact Your Insurance Company (3–6 Hours)

After calling a restoration company, contact your homeowners insurance company to report the claim. Most policies require prompt reporting of water damage. Have your policy number ready and be prepared to describe the damage and its apparent cause.

Ask your insurer about your coverage for water damage, your deductible, and the claims process. Find out whether you need to wait for an adjuster before restoration work begins, or whether you can authorize emergency services immediately. Most policies allow emergency mitigation work to proceed without waiting for an adjuster, as delaying mitigation can worsen the damage.

A reputable restoration company will work directly with your insurance company and can help you navigate the claims process. At Atlanta Water Damage Restoration, we have extensive experience working with all major carriers and can communicate directly with your adjuster on your behalf.

Step 6: What NOT to Do After Water Damage

Just as important as knowing what to do is knowing what to avoid. These common mistakes can significantly worsen water damage:

• Do not use a regular household vacuum to remove water. Standard vacuums are not designed for liquid and can be damaged or create electrical hazards.
• Do not walk on wet carpet or flooring more than necessary. Foot traffic spreads contamination and can damage flooring materials.
• Do not use electrical appliances in wet areas. This includes hair dryers, fans, and any other appliances that could create an electrocution hazard.
• Do not attempt to lift or move heavy wet furniture alone. Wet furniture is extremely heavy and can cause injury. Leave it for the restoration team.
• Do not enter areas with sewage contamination without protective equipment. Sewage contains dangerous pathogens that can cause serious illness.
• Do not wait to call for help. Every hour of delay increases damage and restoration costs.

Why the First 24 Hours Are So Critical

Water damage follows a predictable progression. In the first hour, water spreads rapidly and begins to be absorbed by flooring, walls, and furniture. Within the first 24 hours, drywall begins to deteriorate, wood begins to swell and warp, and metal surfaces begin to tarnish. Most critically, the conditions for mold growth are established within this window.

In Atlanta's warm, humid climate, mold can begin growing in as little as 24 hours after a water damage event. Once mold establishes itself, remediation becomes significantly more complex and expensive. Professional drying that begins within the first few hours can prevent mold growth entirely in many cases.

The bottom line: call a professional immediately, document everything, and let the experts handle the restoration. The cost of professional water damage restoration is almost always far less than the cost of delayed action.
