Why Is My Drain Blocking?

If your drain keeps blocking, there's a reason — and it's rarely just about what you're putting down it. Recurring blockages almost always indicate an underlying structural problem in your pipework that traps debris and causes repeated buildup. Finding the root cause is the key to stopping it for good.

What to Look For

• Blockages that return within days or weeks of clearing
• The same drain always blocks
• Multiple drains blocking together
• Blockages getting more frequent over time
• Slow drainage between blockage episodes
• Bad smells even when drains are flowing

How We Diagnose the Problem

A CCTV drain survey reveals the structural cause behind recurring blockages. Common findings include partial pipe collapses creating snag points, displaced joints catching debris, tree root ingress, belly (dip) in the pipe where waste pools, or incorrect gradient.

How We Fix It

Once we identify the structural issue, we fix it permanently — relining cracked joints, removing roots and sealing entry points, replacing collapsed sections, or correcting pipe gradient. No more repeated clearing bills.
