Common Causes of Blocked Drains in London

When you find out you have a blocked drain it can be incredibly frustrating, especially if you don’t know why it has happened. Thinking about what may have caused the blockage in your drainage system could reduce the time it takes for us to find a solution, as well as making it less likely that the problem repeats itself. Take a look at a few of the common causes of blocked drains:

Tree roots

One of the most difficult drain blockages to rectify occurs when a tree root has found a way into the drainpipe, usually through a small crack in the pipe. Once the tree root has entered the drain, it grows and can cover the entire width of the pipe. If you hear that a tree root is blocking your pipe, do not worry. Our expert engineers have lots of experiencing cutting roots out of drains, so you can count on us to fix your pipes and restore their functionality.

Foreign objects

Drainpipes are designed for wastewater to flow through, so if any other items end up in them there is a risk a blockage will occur. An excess of toilet paper, soap scum, hair, or food scraps can be enough to create a blockage within your drainage system. As can sanitary products, nappies, cooking oil, or any object flushed something down the toilet that shouldn’t have been. No matter what has caused the blockage in your drainpipes, you can trust our talented team to work hard and provide a high-quality solution.

Structural issues or breakages

If your drains are blocked there is a chance there could be a structural issue, perhaps because your pipes are misaligned. Although it is unlikely, there may have been a mistake during the installation of your drainpipes that has only just now become apparent. Alternatively, the blockage may have occurred because your pipes have been damaged or have collapsed. No matter the reason, we will deliver the solution your property’s drainage system requires.

Slope issues

The cause of your drain blockage may not even have anything to do with the pipes themselves. The soil surrounding your drainpipes could have shifted, resulting in the slope of the pipes becoming unbalanced. Drainpipes rely on gravity to work correctly, so if they are moved out of position the impact can be highly detrimental. Slope issues could also have been caused by an error made during the installation process. If there is a slope issue with the drains at your property, our team will swiftly resolve the issue.

I would highly recommend BN Drainage. I called them out to fix a blocked drain, and they arrived within the hour. They quickly identified and fixed the problem, providing a fast, efficient and professional service. They also sent over a job sheet detailing the work they had carried out, which was really helpful and kept me fully informed throughout. Their prices were reasonable, and they were friendly and approachable from start to finish. Overall, a great experience with a reliable company that I wouldn’t hesitate to use again. Highly recommended!

We'd had a blocked manhole and a toilet that wouldn't clear properly for about two weeks, so I was glad to get someone out. A contractor from BN Drainage attended, explained clearly what the problem was, and got stuck in straight away. He was friendly, straightforward and didn't oversell anything. The engineer came out in the morning to finish the job. All sorted.

BN Drainage were incredibly helpful with our pre-purchase CCTV survey. Dan and Barry explained the findings clearly over several phone calls and kindly reviewed repairs carried out by another contractor following their survey. Great communication and support throughout a stressful house purchase. Highly recommend!

This is a bona fide feed back review about BN Drainage Ltd, written with integrity and honesty. We recently discovered the horror of broken gulley drains and leaking water into our basements (i.e. our neighbour and ourselves because the gulley grains were connected) and were introduced to this drain specialist by our local Whatsapp group. From the beginning to the end of the job they have been an excellent company. Courteous and respectful (for us an important part of the relationship with any company); They inspected the drains and we received a detailed breakdown & invoice of the work that had to be done. The cost was very reasonable and much cheaper than we anticipated. It was a big job because our neighbour's drain being connected to ours, meant that they had to do the 2 jobs together. They set a date for the repairs and came on time as planned. We were expecting a big messy job with mud everywhere, but they were respectful of our house and living space and curtailed the mess and mud and cleared away the old drains and debris and left the site clean ready for us to do our home cleaning-up. They removed the old drains, pipes & debris etc from our house altogether. We anticipated that our conservatory tiles would have to be broken during the work (and replicas hard to find since they had been down for many ears), but the engineers found they did not have to do this and preserved our tiles. We received an excellent professionally produced report about their findings (before and after the job) and details of the work they had carried out. They really do deserve a big 'thank you' for a job well done, for a very good cost and deserve a 5 star rating.
