Drain Unblocking

Professional drain unblocking for homes and businesses.

  • Vetted contractors
  • Fully insured
  • Commercial & site work specialists

Whether you are planning ahead or responding to an active issue, drain unblocking helps turn uncertainty into scoped work with predictable timing and clear next steps.

Whether it's a slow-draining sink, an overflowing toilet, or a completely blocked outside drain, our engineers have the tools and experience to clear any blockage fast. We use a combination of rodding, high-pressure jetting, and electro-mechanical equipment depending on the nature of the blockage.

Operational pressure or tight sequencing often makes a generic fix too risky; structured scope and delivery reduce that exposure.

How the service works

We follow a clear, structured approach from first contact to completion. Every job starts with understanding the problem, then we recommend the most appropriate method and deliver with full documentation and reinstatement where needed.

  1. Step 1: Assess the blocked drain and access points

    What this step delivers: Requirements and constraints are confirmed before commitments are made.

  2. Step 2: Choose the right clearance method for the blockage

    What this step delivers: This stage improves certainty and reduces avoidable rework.

  3. Step 3: Clear the blockage using jetting, rodding or mechanical tools

    What this step delivers: This stage improves certainty and reduces avoidable rework.

  4. Step 4: Test the drain with water flow

    What this step delivers: Completion is validated and handed over with clear next steps.

  5. Step 5: CCTV survey to check for underlying issues

    What this step delivers: Requirements and constraints are confirmed before commitments are made.

Our approach focuses on selecting the right method based on site conditions and project requirements, then documenting each stage so decisions stay clear throughout delivery.

Drainage cost and timing usually depend on drain condition, access to the affected run, and whether supporting repair or reinstatement is required alongside the core work.
