Signs You Need Our Drainage Unblocking Services
A complete blockage is obvious, but often your drains will give you warning signs first. If you notice any of the following, it’s time to call in the professionals before the problem gets worse:
- Slow Draining Water: Sinks, showers, or baths are taking longer than usual to empty.
- Gurgling Sounds: Strange noises coming from your plugholes or pipes.
- Foul Odours: Unpleasant smells rising from drains are a classic sign of trapped, decaying waste.
- Rising Toilet Water: Water level in the toilet bowl rises unusually high when you flush.
Ignoring these signs can lead to wastewater backups and internal flooding. Our emergency drain unblocking team is ready to help 24/7.


Our Advanced Drain Unblocking Methods
DIY chemical solutions can damage your pipes. We use powerful, professional-grade equipment to provide a lasting drain care fix without risking your plumbing.
High-Pressure Water Jetting (HPWJ): Our most effective solution for blockages. Van-mounted jetters clear obstructions and scour pipe walls of grease and sludge to prevent future build-up.
Electro-Mechanical Cleaning (EMC): Used for delicate pipes or to tackle hard obstructions. A high-speed, spinning cutting head is fed into the pipe to grind away scale, solidified waste, or tree roots.

Frequently Asked Questions

What does your drain unblocking service cost?
We offer competitive fixed-price rates for most standard drain unblocking jobs. The price depends on the complexity, but we will always provide a full quote for you to approve before any work begins.
How quickly can you get to my property in London?
As a 24/7 emergency service with engineers located across the region, we aim to be with you within just a few hours of your call.
Are “flushable” wet wipes really safe to flush?
No. Most wipes do not break down in the sewer system and are one of the single biggest causes of domestic blockages. We advise bagging and binning them.
Is your drain unblocking service guaranteed?
Yes, we stand by the quality of our work. Our goal is to provide a lasting fix, and we ensure you are completely satisfied with the result.
What happens if the problem is more serious than a simple blockage?
If our engineer suspects a bigger issue, like a damaged or collapsed pipe, they are equipped to investigate further. We can use advanced CCTV drain survey cameras to find the exact cause and location of the fault. Afterwards, we will explain the findings and provide a clear, no-obligation quote for any necessary repairs.
What are the best ways to prevent my drains from blocking?
The best prevention is being careful about what goes down them. Avoid pouring fats, oils, or grease down the sink; let them cool and dispose of them in a bin. Use drain catchers in kitchen sinks and showers to stop food and hair from building up. Finally, only flush the three P’s: pee, poo, and (toilet) paper.
Do you work on commercial properties as well as homes?
Yes, absolutely. We provide a full range of drainage services for commercial clients, including restaurants, offices, retail units, and industrial sites. Our engineers are experienced in handling the larger-scale and more complex systems often found in commercial properties, from emergency blockages to preventative maintenance plans.
