Sink & Basin Waste Replacement
Sink & Basin Waste Replacement
If water seeps around the plug hole or the pop-up won't hold water, the waste unit's seals have failed. Replacing the waste is straightforward and stops damage to the cabinet below.
Sink & Basin Waste Replacement in North London, done properly the first time
We remove the old waste, clean the sealing face, and fit a new sink, basin or bath waste with fresh rubber and fibre washers and the correct sealant — over-sealing is what makes many DIY replacements leak. Slotted and unslotted wastes matter too: fit the wrong one and the overflow can't drain.
For pop-up and click-clack wastes we set the mechanism so it seals fully but still releases first time. We also check the trap and tail connections underneath, because that joint is usually disturbed when the waste is changed. Serving Barnet, Finchley, Enfield and North London.

Your questions, answered
Why does my basin leak only when it's full?
That's usually the overflow route or an unslotted waste fitted to a basin with an overflow. Fitting the correct slotted waste fixes it.
My plug won't hold water — is that the waste?
Yes, normally a worn seal or a misadjusted pop-up rod. We re-set or replace the mechanism so it seals and releases properly.
Can you replace a waste without removing the sink?
In most cases yes, working from above and below. Very tight vanity units occasionally need the basin easing forward.
