Key takeaways
- First stop the water and cut the electricity in the affected area if water is near sockets.
- Find the source: the neighbour upstairs, a shared pipe, the roof. Warn them and the building manager.
- Photograph and film everything before cleaning, and keep damaged items.
- Declare the claim to your home insurer quickly, often within five working days.
A brown stain spreading on the ceiling, drops falling on the sofa, a puddle under the sink: water damage is one of the most common home insurance claims in the world. It often involves two homes and two insurers, so it can turn into a dispute if you don’t act in the right order.
1. Stop the water and stay safe
- If the water comes from your home, close the main water valve.
- If it comes from upstairs, go and knock: the neighbour may not know. If nobody answers, call the building manager or caretaker, who may be able to shut off the water supply.
- If water is near electrical sockets, lights or appliances, cut the power to that area at the fuse box.
2. Protect your belongings
Move furniture, electronics and documents away from the water, put buckets and towels down, and open windows to start drying. Don’t throw anything away yet, even if it’s ruined: the insurer’s assessor may want to see it.
3. Record the damage
Before you clean or repair, film a slow walk-through of each affected room, then photograph the ceiling, walls, floors, furniture and damaged items up close. Note the date and time you noticed the leak. Keep doing this over the following days, as stains and mould can spread. Our /blog/how-to-document-an-incident/ guide explains how to keep your records credible.
4. Find and confirm the source
Ask the neighbour upstairs to check their bathroom, kitchen, washing machine and pipes. If the source is a shared pipe or the roof, it’s usually the building’s responsibility. Many countries use a joint water-damage report, similar to the car accident report, signed by the people involved. If not, exchange names, addresses and insurer details in writing.
5. Declare to your insurer
In most countries, you declare the damage to your own home insurer, even when the neighbour caused it; insurers then settle between themselves. Deadlines are short, often five working days. Send your photos, the report or the neighbour’s details, and a list of damaged items with their value. Keep the receipts for emergency repairs and drying.
Tenants should also inform their landlord in writing: the landlord’s insurance may cover the structure (ceilings, walls), and yours the contents.
6. If the neighbour won’t cooperate
Write a polite message summarising the facts and asking for their insurer’s details. If there’s no answer, involve the building manager, then send a formal letter (see /blog/how-to-write-a-formal-demand-letter/). Your insurer can often handle the claim even without the neighbour’s cooperation if you have good evidence. For ongoing conflicts, see /blog/neighbour-dispute-what-to-do/.
Frequently asked questions
Who pays for the repairs?
It depends on the source and local rules. Often, each party’s insurer covers the damage in their home, then recovers costs from the insurer of whoever is responsible. Your contract and the assessor’s report decide.
Can I start repairs before the assessor visits?
Do emergency work to stop the damage and keep invoices, but wait for the insurer’s approval for major repairs. Photos taken before the work are essential.
What about mould after the leak?
Dry the area quickly and photograph any mould that appears. Report it to your insurer and landlord: it can be part of the damage and affect your health.
