How to Clear a Blocked Outside Drain

A blocked outside drain is one of the most common drainage problems in UK homes. In many cases, you can clear a simple blockage yourself with basic tools. However, recurring blockages or those caused by structural damage need professional attention. Here's how to tackle it safely and when to call for help.

What to Look For

• Step 1: Lift the drain cover carefully (use a screwdriver to lever if stuck)
• Step 2: Check for visible blockages — leaves, debris, fat buildup
• Step 3: Try clearing with drain rods — push and twist, don't pull
• Step 4: Flush with a hosepipe to check if flow is restored
• Step 5: If the blockage won't clear, it's deeper — call a professional
• Step 6: Never use chemical drain cleaners in outside drains — they damage pipes

How We Diagnose the Problem

If DIY methods don't clear the blockage, the cause is likely deeper in the system — a partial collapse, root ingress, or a blockage beyond reach of drain rods. Professional CCTV investigation reveals the exact cause and location.

How We Fix It

Simple blockages are cleared on site with jetting. If CCTV reveals structural damage, we provide repair options — from relining for cracks and root damage to excavation for collapses. We address the root cause to prevent the blockage returning.
