Drain repairs in North London

When a homeowner in North London noticed a persistent sewage smell in their kitchen, they called our BN Drainage team for a solution. See our North London drain repair case study. Our team conducted a detailed drain survey and quickly identified the problem as a damaged pipe hidden beneath the kitchen floor.

The client was heading away for the weekend and needed the problem resolved before their return. To fix the issue, we carefully removed the kitchen units and excavated them internally to reach the faulty pipe. The damaged section was replaced efficiently, and once the repair was complete, we restored the kitchen to its original state, ensuring no trace of disruption.

The biggest challenge was the tight timeframe. So, we worked through the weekend and ensured that the job was completed in just 2 days’ time. The client was welcomed with a fresh, odour-free kitchen upon their return.

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.
