Is Your Drain Blocked? We Fix It Fast.

A blocked drain is more than just an inconvenience—it can lead to foul odours, water damage, and severe structural issues if left untreated. Our expert engineers use state-of-the-art equipment to diagnose and clear blockages quickly and effectively.

Signs You Have a Blocked Drain

  • Gurgling sounds from toilets or sinks
  • Slow draining water
  • Bad smells from plugholes
  • Rising water in manholes
  • Flooding around drains

If you’re in Watford, Bushey, Rickmansworth, Abbots Langley, St Albans, Hemel Hempstead, or anywhere in Hertfordshire, we can diagnose and clear the issue the same day.

How We Unblock Drains (Better Than Standard Plumbers)

High pressure water jetting

Most plumbers only use rods. We use professional drainage equipment to ensure the blockage is fully removed — not just pushed further down the pipe.

  • Manual Rodding & Plunging: Perfect for internal blockages, toilets, sinks and soft debris.
  • High‑Pressure Water Jetting (HPWJ): Ideal for external drains, fatbergs, grease, silt and scale. Our jetting units operate at 3,000+ PSI for a deep clean.
  • Electro‑Mechanical Cutting: Used for tree roots, concrete, hard scale and stubborn obstructions.

Frequently Asked Questions About Drain Unblocking

How much does it cost to unblock a drain?

We offer a fixed fee structure with absolutely no hidden costs. The exact price depends on whether it is a simple manual rodding job or requires high-pressure water jetting. We do not charge a call-out fee. Call us for a transparent, no-obligation quote over the phone.

How quickly can you arrive in an emergency?

As a local company covering London and Hertfordshire, we pride ourselves on rapid response times. In emergency situations involving overflowing sewage or blocked toilets, we aim to be at your property within 1-2 hours.

What if the blockage keeps returning?

If a drain repeatedly blocks, it indicates a structural issue like root ingress, displaced joints, or a collapsed pipe. During our visit, we can conduct a CCTV Drain Survey to identify the root cause and recommend permanent repair solutions.

Can you unblock commercial grease traps?

Yes. We have specialized vacuum tankers and high-temperature jetting equipment specifically designed to clear “fatbergs” and emulsified grease from restaurant and commercial kitchen drainage networks.
