Blocked Drain drainage service

Blocked Drain

Fast unblocking of drains using high-pressure jetting.

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

The scope of blocked drain varies by site, but the objective is consistent: reduce ambiguity, choose a practical method, and deliver a result that holds up under real operating conditions.

Blocked drains are one of the most common drainage problems. Whether caused by fat, grease, wet wipes, tree roots, or debris buildup, we use high-pressure water jetting and specialist equipment to clear even the most stubborn blockages. We also investigate the cause to help prevent recurrence.

That usually translates into clearer procurement decisions: fewer assumptions, better-aligned trades, and a documented path if priorities change mid-programme.

Frequently Asked Questions

How much does drain unblocking cost?
Simple unblocking starts from £80–£150. High-pressure jetting costs £150–£300. Emergency out-of-hours callouts cost £200–£400.
Why do my drains keep blocking?
Recurring blockages usually indicate a structural problem — partial collapse, root ingress, or pipe gradient issues. A CCTV survey finds the cause.
Can blocked drains cause damage?
Yes. Persistent blockages can cause sewage backflow, damp, bad smells, and even structural damage if the pipe collapses.
What practical factors should be reviewed first?
Review drain condition, access to runs, and whether related repair work is needed early to keep scope realistic and avoid unnecessary rework.
