Emergency Drain Unblocking

A completely blocked drain can cause sewage to back up into your property within hours, creating a health hazard and causing damage. Our emergency unblocking service provides rapid response to clear blockages before they escalate into serious problems.

The commercial value of resolving emergency drain unblocking early is fewer delays, clearer budgeting, and reduced repeat disruption.

When you might need this

Teams usually investigate emergency drain unblocking when early warning signs start affecting reliability, compliance, or project timelines. This is often the point where decision makers move from observation into scoped technical action.

Signs and common situations

The symptoms below are the most common triggers we see before diagnosis and repair planning.

  • Toilet completely blocked and overflowing
  • All drains in the property backing up simultaneously
  • Sewage coming up through shower or bath drains
  • External drains overflowing onto the property
  • Water rising in manholes

What to expect from the work

We quickly assess where the blockage is located — whether it's a local issue in one fixture or a main drain blockage affecting the whole property. High-pressure jetting equipment and CCTV cameras are used to locate and diagnose the cause.

Practical steps to a reliable outcome

We clear the blockage using high-pressure jetting, then carry out a CCTV survey to check whether the blockage was caused by an underlying problem like a collapse or root ingress. If structural damage is found, we provide a quote for permanent repair.

Cost and complexity factors

Cost and complexity usually depend on access constraints, total scope, existing condition, and whether related works need to be coordinated in the same programme window.
