  • I have had really bad experiences with other drainage companies that billed me above what we agreed on due to call-out charges and hidden costs for quotation requests. At J Snow Drainage London they used great drainage equipment without extra charge! I will surely recommend them for all drain installation, drain unblocking, and drain maintenance in London residences and businesses.

    Michael Cunnington Golders Green London NW11
  • I would like to simply say Wonderful Job! My friend called you and a few minutes one of your engineers turned up right in front of our house in your drainage operations van. The drainage equipment – CCTV drain survey and the water jetters – just did the trick; we haven’t had a problem since. Great service, J Snow Drainage London!

Blocked Drain Repairs London

Why choose J Snow Drainage London ?

Customer service is our main priority and we understand that any kind of leak or blockage can rapidly become a large scale problem. So we aim to have your drains in working order quickly, leaving you with a clear system that runs smoothly and efficiently.


What causes blocked drains ?

External drains can be blocked by leaves, damage caused by tree roots and many other factors including broken pipes. Internal drains such as you find in kitchens, toilets and bathrooms, are often blocked by a build up of hair, wipes, tissues, paper towers, limescale & even soap debris.


Frequently we find it’s just a build-up of what’s gone into the drain such as grease, silt, leaves, that causes the problem, which is just part of regular wear and tear. But sometimes it can be due to hard to flush items such as sanitary products or paper towels causing pipes to clog and obstructing the water flow. In other cases, and this is where a CCTV survey is particularly useful, it might be due a structural defect or breakage caused by subsidence, tree roots or pipe corrosion. Whatever the nature of the problem, from pipe damage to hair blockages and everything in-between we have the tools and experience to fix it.


There are steps you can take to prevent your system becoming blocked, but once it’s happened it can often be difficult to fix yourself, which is why you need a professional drainage company. We strive to have all your drains fixed in the fastest time frame possible with a minimum of fuss and disruption.


How do you repair my blocked drain ?

To clear your drain we will typically use high-pressure water jetting as it’s usually the most effective treatment method available. We also use a CCTV drain survey as the cameras allow our engineers to pinpoint the exact location of the blockage or leak which helps us to diagnose the problem without causing any further damage to the pipes.


We use the most advanced technology available to us, to save you both time and money that may be wasted on unnecessary drain replacements. We’re are also professional – if our engineers believe that your system is unfixable then we will provide you with the best honest impartial advice.
