Common Drainage Problems We Solve

Blocked External Drain

Leaves, debris, grease, and roots are common culprits. We clear the blockage and inspect the drain to ensure it's flowing freely and there's no structural damage underneath.

Slow-Draining Sinks & Baths

Hair, soap scum, and grease build up over time and restrict flow. We clear the blockage from the drain through to the stack and advise on maintenance products to keep it clear.

Drain Flooding

Water backing up from a drain or manhole cover is an emergency. We attend fast, identify whether the issue is a blockage, collapse, or capacity problem, and put a fix in place immediately.

Drainage FAQs

How do you unblock a drain?

We use a combination of manual rodding, high-pressure water jetting, and specialist drain tools depending on the severity and location of the blockage. For stubborn or recurring blockages, we can carry out a CCTV survey to identify the root cause.

What causes drains to keep blocking?

Recurring blockages are often caused by fat and grease build-up, tree root ingress, collapsed pipework, or a foreign object lodged in the pipe. A CCTV drain survey lets us see exactly what's happening inside the drain and recommend the right long-term fix.

Do you offer CCTV drain surveys in London?

Yes. We carry out CCTV drain surveys across Greater London. A survey gives you a full picture of your drainage system's condition — useful for pre-purchase surveys, recurring blockage diagnosis, and insurance claims.

Can you fix a collapsed or broken drain?

Yes. We repair and reline collapsed, cracked, and broken drains across London. Where possible, we use no-dig drain lining technology to repair pipework without excavation, minimising disruption to your property.
