When a blocked drain is more complex than typical problems such as drains clogged with a build up of scale or fat, a cctv drain survey will help analyse and plan a solution. Our South West London drain surveys will often find problems such as a collapsed drain or a wedged solid object.
With the exact position of the drainage problem our qualified and professional drain cleaners can solve the issue with little disturbance to your domestic or commercial property.

Aside from using a jetter, there are many products available to unclog a drain or clear a blockage. Caustic liquids are used to dissolve grease and hair clogs, usually in the form of Sodium Hypochlorite, Sodium Hydroxide or Potassium Hydroxide.
This theoretically results in dense foam forming a seal over the waste pipe, trapping caustic gases inside the pipe, with an additional foam coating applied down the waste pipe to remove more than the initial blockage causer.
An alternative to jetting (which can be at pressures of up to 4000 Psi), “air bursts” of Carbon Dioxide can instead be used to rupture blockage membranes. In addition, simple boiling water can sometimes be enough to clear a blockage, or a combination of baking soda and vinegar for a more ecologically friendly, albeit less effective approach.
