Drain Descaling in Leicester

What Causes Scale and Build-Up

Hard water deposits calcium carbonate on the inside of waste pipes — the same process that furs up a kettle. Over years, these deposits build into a hard scale that progressively reduces the bore. Cooking grease, soap residue and rust from cast-iron pipes add to the layer. The result is a pipe that drains slowly even after jetting because the bore itself has narrowed.

Signs That a Drain Needs Descaling

Recurring slow drains that clear after jetting but return within weeks; a drain that has never been cleaned on a property more than 20 years old; a white or grey crust visible around a plug hole or inside a trap; a drain survey that shows heavy scaling without a discrete blockage.

How We Descale

Mechanical rotary cutting tools break up hard scale deposits on the pipe walls, after which high-pressure jetting removes the debris. For heavily scaled clay and cast-iron pipes, we may make two passes — rotary cutting first, then a clean jet — before a final CCTV check to confirm the bore is restored.

Descaling Before Relining

If you are having a drain relined, descaling is always done first. The resin liner bonds to clean pipe wall; a scaled surface reduces adhesion and the life of the liner. We always descale before relining as part of the same visit.
