Grease and fat build-up — the most common cause of kitchen sink blockages. Fat poured down the drain solidifies further down the pipe, gradually restricting flow until the sink stops draining altogether.

Hair and soap residue — bathroom basin and bath blockages are almost always caused by a build-up of hair and soap scum in the trap or further down the waste pipe.

Foreign objects — small items that fall into a sink can lodge in the trap and cause an immediate blockage. We retrieve and clear these without damaging your pipework.

Scale and debris — in older properties, scale build-up inside pipes can gradually reduce the internal diameter until flow is severely restricted. This often requires more than a simple plunge to clear.

Root ingress or collapsed drain — for outdoor drain blockages that keep recurring, the cause is sometimes structural. We'll advise if we find evidence of this and discuss the appropriate next steps.
