External Drain Unblocking

What external drain unblocking covers

External drain unblocking is designed to restore normal drainage and reduce the risk of repeat issues. The service typically includes:

• Locating the most likely point of restriction in outside pipework, gullies, or channels
• Clearing the blockage using appropriate tools (for example rods or high-pressure jetting)
• Removing built-up debris where accessible (silt, leaves, grease, wipes, food waste)
• Checking flow after clearance to confirm the drain is running normally
• Practical advice on what caused the issue and how to help prevent a recurrence

When this service is most useful

You may need external drain unblocking if you notice slow drainage from sinks or appliances, gurgling sounds, foul odours outdoors, or water backing up at a gully. It is also common after heavy rain when leaves and silt collect, or when a drain has not been used for a while. For landlords and small commercial sites, it can help resolve issues quickly and minimise disruption.

What happens during the visit

The work starts with a few checks to narrow down where the blockage is and what is likely causing it. The drain is then cleared using the most suitable method for the pipe size, access point, and type of obstruction. Once cleared, the flow is tested and the area is left tidy, with clear next steps if any further investigation is needed.

After the drain is clear

After normal flow is restored, you will be told what was found and what to watch for. If there are signs of a recurring problem, such as root ingress or a damaged section of pipe, you will be advised on options to address it. Simple preventative steps can often reduce future callouts, especially around what goes into sinks, toilets, and gullies.
