5 Warning Signs of a Collapsed Drain

5 Warning Signs of a Collapsed Drain

A collapsed drain is a serious problem and must be dealt with immediately to help prevent further damage. Unfortunately, if you don’t know what to look out for, it can sometimes be difficult to identify a collapsed drain until the damage becomes more severe.

Unfortunately a collapsed drain is on the more serious side of drainage issues and required immediate attention to rectify the problem. Here are some of early-warning signs of a collapsed drain you should look out for…

Signs of Damp

If your drain has collapsed, the flow of wastewater will be seriously disrupted. This will often lead to water flowing into the ground surrounding the drainpipe.

If the pipe is located under or close to your home, you may notice signs of damp on the floor or walls.

Unfortunately, the signs of damp are not immediately obvious so this could indicate that your drain may have been damaged for some time, so it’s important to investigate the source of the problem immediately at the first signs of damp.

Slow Draining Water

An early indication of a drainage problem is the sudden drop of performance of your drains. If you’ve started to notice that your sinks and toilets are draining slower than usual, it’s important to get the problem checked out as quickly as possible.

The most cost-effective way to identify the cause of the issue is by carrying out a thorough CCTV drain survey conducted by a professional drainage company to quickly identify the cause of the problem and provide you with the most cost effective fix.

While it could simply be a blockage that needs to be cleared, it could also be caused by a collapsed pipe so don’t delay in calling out the professionals.

Cracked Walls & Structural Damage

If a drain has collapsed beneath your home, it may have gone unnoticed for some time. If you start to notice cracks and structural damage to your property, make sure to investigate the problem immediately. If left untreated for too long, the cracks will only become worse, resulting in an even more costly repair.

Sewage Smells

If you’ve started noticing strange odours coming from your drains this is usually an early sign of a drainage problem. Whilst the cause of the issue could simply be a blockage rather than a collapsed drain, it’s important to identify the cause of the problem quickly.

If the odours happen regularly after the drain has been cleaned, then this is a sure sign of a more serious problem such as a collapsed drain somewhere along the drainage system.


A collapsed drain can cause the ground located around it to sink or subside over time. This is commonly one of the more obvious visual signs of a collapsed drainpipe. If you’ve noticed a visible slump or indentation in the ground around your property it is imperative to get the problem investigated and fixed as quickly as possible by a professional London drainage contractor.
