How We Clear Blocked Drains
Every blockage is different, which is why we use a combination of proven techniques and modern equipment. Our process is thorough but efficient.
First, we locate the cause of the blockage. This might be a build-up of fat and grease, debris, scale, or even tree root intrusion. Once we know what we’re dealing with, we choose the right method to clear it.
Most jobs involve high-pressure water jetting (HPWJ). This is one of the most effective ways to remove stubborn blockages and restore full flow. It doesn’t just punch a hole through the blockage, it cleans the pipe walls as well.
For more complex issues, we use:
- CCTV drain surveys to inspect inside the system
- Rotary mechanical machines for solid obstructions
- Root cutting and descaling tools to restore pipe capacity
Before we leave, we always confirm that the system is flowing correctly. Where needed, we can provide CCTV footage as proof of the work carried out.
Fixed Prices, With No Call-Out Fee
One of the biggest concerns people have when booking drainage services is cost. We’ve built our service around transparency.
At Flow Sure Drains, we:
- Don’t charge a call-out fee
