How Do I Handle a Leak From the Unit Above Me?
Last updated October 25, 2026
The short answer
Stop the Water First
Your first move is to stop the flow if it is safe to do so. Find the shutoff valve for the water line feeding the unit above, often in a utility closet or behind an access panel. If you cannot reach it or do not know where it is, turn off the main water supply to your building or ask the neighbor to do it.
If the leak is from a specific appliance like a washing machine or dishwasher, unplug it and close its supply valve. Do not enter a room where water is near electrical outlets or appliances. Your safety comes before saving property. If you feel unwell or see signs of structural damage, leave the area and call for help.
- Locate your shutoff valve now and write down where it is.
- Keep a wrench near the valve for quick access.
- Turn off electricity to affected rooms if safe.
- Move furniture and rugs away from the wet area.
- Place buckets or towels under active drips.
- Take photos of the leak and damage for your records.
Protect Your Belongings
Once the water is off, focus on saving what you can. Move electronics, documents, and valuables to a dry spot. Use plastic sheeting or tarps to cover furniture that cannot be moved. Remove wet carpets and rugs if you can do so without straining yourself. The sooner items dry, the better the chance of saving them.
Do not throw away damaged items yet. Keep them for inspection, as your insurance company may need to see them. Dry books and papers by placing them in a freezer or using fans, but do not use heat sources that could warp them. Keep a list of everything that got wet, along with photos.
Document Everything
Documentation helps with insurance claims and repairs. Take clear photos of the leak, the water stains, and any damaged items. Write down the time you noticed the leak and how long it lasted. Note which rooms and surfaces were affected. This record will be useful when you talk to your insurance company or the pros.
Policies vary, and your insurer decides what is covered. Contact your insurance company soon after the leak to report the incident. Ask what documentation they need and what steps to take next. Keep copies of any correspondence and receipts for supplies you buy, like fans or buckets.
Dry the Area Thoroughly
Moisture can seep into walls, floors, and subfloors, leading to mold and rot. Use fans, dehumidifiers, and open windows to speed up drying. Remove baseboards and drill holes in drywall if water has wicked up, but only if you are comfortable doing so. The pros use moisture meters to find hidden water pockets.
If the leak is large or has soaked into drywall or wood, bring in local water damage pros for extraction and structural drying. They have equipment that reaches deep into materials. Do not delay, as mold can start growing within a day or two. The pros can also map moisture to ensure everything is dry before repairs begin.
Coordinate with Your Neighbor
Talk to the neighbor above you calmly and clearly. They may not know about the leak yet. Share what you have found and ask them to check their plumbing. If they are unresponsive, your building manager or landlord can help. Keep communication respectful, as this can reduce friction later.
If the leak came from a shared pipe or the building's structure, the responsibility may differ. Your insurance company can help clarify what is covered. For repairs to your unit, you may need to work with a plumber or a drywall professional. The pros can handle the water damage cleanup, but the source fix is usually a separate job.

Who pays for the damage from a leak above?
It depends on the cause and your insurance policies. Your insurance company may cover your belongings and unit, while the neighbor's policy may cover their negligence. Policies vary, and your insurer decides what is covered. Check your policy and talk to your insurance company for guidance.
Should I turn off the main water supply?
Yes, if water is gushing and you cannot stop it at the source. Turning off the main valve stops the flow to the entire building. Know where the main shutoff is, often near the water meter or in a basement. If you cannot find it, ask the building manager or a plumber for help.
How long does it take for mold to grow after a leak?
Mold can begin to develop within 24 to 48 hours in damp conditions. That is why quick drying is critical. Use fans and dehumidifiers right away, and remove wet materials. If mold appears, a mold professional can assess and treat it. Do not ignore musty smells, as they often signal hidden growth.
