What should a landlord do in the first 24 hours after a water leak in a rental?
Stop the water, make the area safe, take photos, start drying, and call a plumber, your insurer and any affected tenants, in that order. The EPA says to dry wet materials within 24 to 48 hours to keep mold from taking hold, and to fix the source of the water first. The first day decides whether a leak is a small repair or a large claim.
The first hour: stop it and make it safe
- Ask the tenant to shut the fixture's valve under the sink or toilet, or the unit's main shut-off. If they cannot find it, tell them where it is before the next leak: write shut-off locations in the move-in packet.
- If water is near electrical outlets, ceiling fixtures or the panel, tell the tenant to stay away from them and turn off power to that area at the breaker if it is safe to do so.
- Ask for photos and a short video from the tenant: where the water enters, what is wet, and any stains.
- Send a plumber or a handyman, depending on the source. Ask the vendor to confirm the source, not only stop the symptom.
If a supply line has burst or the water cannot be stopped, shut off the main for the building and call a plumber on an emergency basis.
Hours two to six: document before you dry
Take wide and close photos of every wet area before anything is removed. Note the date, the time you were told, and the time the water was stopped. Insurers ask for these, and tenants may need them for their own renter's insurance claim.
- Photos of damaged ceilings, walls, floors and belongings.
- A short list of what the tenant says was damaged.
- The plumber's invoice or note naming the cause.
- Any moisture-meter readings from a restoration company.
Hours six to twenty-four: dry it
The EPA says wet materials dried within 24 to 48 hours of a leak usually do not develop mold, and porous materials such as ceiling tiles and carpet may need to be thrown away if mold takes hold. Start extraction and drying the same day: fans, dehumidifiers, lifting wet carpet and pad, and opening wall cavities if a restoration company advises it.
For anything beyond a small spill, call a water restoration company. They measure moisture and can tell you what to keep and what to remove. Do not paint over a wet stain.
Tell the people who need to know
| Who | What to say | When |
|---|---|---|
| Affected tenants | What happened, what you are doing, when workers will enter and what to move | Right away, then after each step |
| Tenants below or beside | Same, plus an invitation to report new stains | Same day |
| Your insurer | A leak occurred, the date, and your photos | Same day or next business day |
| The tenant's renter's insurer | Up to the tenant | Remind the tenant |
Policies set their own notice and claim deadlines, so read yours; see insurance claim deadlines in Texas and Florida for how short some can be. This is general information, not legal advice.
What a fast response saves
Example a made-up toilet supply line fails on a Friday evening. The tenant shuts the valve within 20 minutes, the plumber replaces the line for a made-up $180, and a restoration company dries the bathroom for $450. Total $630. Had the leak run over the weekend, the made-up cost to replace drywall, subfloor and flooring might have been $4,000 or more.

Questions
- Who pays for the tenant's damaged belongings?
- Usually the tenant's renter's insurance, unless the landlord was negligent. State law and the lease matter here.
- Does the tenant owe rent while the unit is being dried?
- If the unit is unusable, many states allow a rent reduction or release. Check your state's rule and talk to the tenant early.
- Should I call the insurer for a small leak?
- Check your deductible and policy, but notify the insurer if damage may exceed it or if there may be hidden damage.
