What We Clear, Fast
Blocked drains don’t come with a warning, and they rarely wait for a convenient time. Whichever fixture is affected, we carry the tools to clear the vast majority of blockages on the first visit.
- Toilet Unblocking: the most common emergency call-out, usually cleared with rodding or jetting within the hour of arrival.
- Sink Unblocking: kitchen and bathroom sinks cleared of grease, food waste and soap build-up.
- Bath Unblocking: slow-draining or fully blocked baths cleared quickly, including shared or older waste pipework.
- Shower Unblocking: hair and soap scum build-up cleared from shower drains and traps.
24/7 Emergency Drainage You Can Rely On
At Cooper & Sons Drainage, we understand that a blocked drain can range from a minor inconvenience to a genuine emergency, especially when it’s the only toilet or bathroom in the house. That’s why our emergency line runs genuinely around the clock, not routed through a call centre for a next-morning appointment.
Every call-out is free, so you know what you’re paying before any work starts. Our team will assess the blockage, explain what’s needed, and clear it using the least disruptive method available, rodding or jetting first, with CCTV survey and excavation only where genuinely necessary.
Every completed job is covered by our 1-year guarantee, giving you peace of mind that the fix will hold. We’re also proud of our reviews from satisfied customers, which you’ll find in the footer below.

Frequently Asked Questions
We always confirm the price before starting work, so there are no surprises on the invoice.
We prioritise genuine emergencies and give you a realistic arrival window when you call.
Yes, an out-of-hours surcharge applies.
Not usually. Most blockages, including root ingress, are cleared with jetting and rodding via existing access points. We only recommend excavation once a CCTV survey shows it's genuinely needed.
Every completed job is covered by our 1-year guarantee.
Never. Every job is completed entirely by our own team. This is how we guarantee consistent quality on every call-out.
For most straightforward jobs, no, though access to the affected fixture is needed. We'll keep you updated throughout and confirm before we leave.
