Waste Trap Leak Repair
Waste Trap Leak Repair
Traps hold a water seal that keeps drain smells out of the room. When one cracks, loosens or dries out you get either a puddle in the cupboard or a persistent drain smell.
Waste Trap Leak Repair in North London, done properly the first time
We replace bottle, P and S traps on sinks, basins, baths and showers, fit the correct depth of seal for the waste run and make sure appliance spigots are connected — not just pushed on. Compression nuts on plastic traps loosen with heat and movement, which is why so many kitchen traps weep after a year or two.
Where the smell rather than the leak is the problem, we check the seal depth, look for a siphoning waste and inspect for a blocked or missing air admittance valve. Those are common in Barnet loft conversions and rear extensions where wastes were run long and flat.

Your questions, answered
Why does my kitchen sink smell even though it drains fine?
Usually a shallow or dried-out trap seal, or a siphoning waste pulling the seal out. Fitting the right trap and venting the run solves it.
Can a leaking trap just be tightened?
Sometimes, but if the washers are distorted or the trap is cracked it will weep again. We replace the washers or the whole trap so it stays dry.
Do you fix shower and bath traps under the floor?
Yes. Where access is limited we work through the bath panel or an existing access hatch, and can form a neat hatch if none exists.
Do you cover Barnet the same week?
Yes — most trap repairs across EN4, EN5, N20 and neighbouring North London postcodes are booked within a few working days.
