Drain Unblocking

Blocked drain? We'll clear it fast.

A blocked drain left untreated can escalate from a minor inconvenience to structural damage, sewage backflow, and costly repairs. Uriel Infrastructure provides rapid-response drain unblocking for residential and commercial clients across London and the South East, using professional-grade high-pressure jetting equipment operated by WJA-certified technicians.

We don't cut corners. Every clearance job is diagnosed, cleared, and documented — so you know the blockage is fully resolved, not just temporarily pushed through.

High-Pressure Water Jetting

Our primary method for clearing blockages is high-pressure water jetting — a WJA-approved technique that removes even the most stubborn accumulations of grease, scale, root ingress, and debris. Unlike manual rodding, jetting clears the full bore of the pipe, restoring it to near-original flow capacity. Our operatives are fully WJA trained and work safely with high-pressure equipment on all pipe diameters.

Residential Drain Unblocking

We handle blocked drains across all residential property types — from terraced houses and flats to large detached homes. Common causes include:

Grease and food waste in kitchen drains
Hair and soap build-up in bathroom drains
Wet wipes and sanitary products in toilet drains
Root ingress into underground drainage
Collapsed or offset joints causing partial blockages

We diagnose the cause, clear the blockage, and advise on preventive measures — with a full written report provided for your records.

Commercial & Emergency Drain Clearance

For commercial premises, a blocked drain can mean business disruption, health and safety risk, and regulatory consequences. We prioritise commercial callouts and offer contracted service agreements for businesses requiring regular maintenance. Our 24/7 emergency response means we're available when you need us most — not just during office hours.

After the Job

Every drain unblocking job is followed by a CCTV drain survey recommendation if underlying structural issues are suspected. We provide a full service report on completion, which can be used for insurance claims, property transactions, or compliance records.
