Escape of water damage is one of the most common types of domestic property damage claims1, according to the Association of British Insurers.

However, buildings insurance will usually only cover water leaks and water damage if the cause is sudden or accidental such as when a pipe burst. Gradual water damage, which occurs slowly and over time, is very rarely covered by a buildings insurance policy.

Gradual damage is often caused by normal wear and tear as, over time, pipes and connections can deteriorate.  While water damage can seem sudden, it may have been happening over a long period. Pipes and plumbing systems aren’t easily visible, hidden within your home’s walls. So, if a leak was slowly building up, you likely wouldn’t notice it until a major water damage incident occurs.

That’s why it’s always advisable to ask leaseholders in the block of flats to check their plumbing, and for building managers to check the common areas regularly. Even a leaky tap or cistern or a perished washer on white goods can add up to big problems over time,

Even when the damage is sudden, the cost of consequential damage may not be covered – such as if the water from a burst pipe damages décor or fitted kitchen units or cupboards. Similarly, the costs of finding leaks (trace and access) leaks may not be covered, which means that the cost of making good after lifting floorboards etc to find the source may not be reimbursed.

Talk to your broker and make sure you have the cover you need and are clear on what is not insured so everyone in the building can take precautions. All Deacon blocks of flats insurance policies offer trace and access cover.
