Why drains block in Slough
Much of Slough’s housing was built in a hurry. When the Trading Estate opened in 1920 it pulled in major employers and thousands of workers, and the streets of Cippenham, Chalvey and Manor Park filled with semis and terraces during the interwar decades. The clay drains laid beneath those homes are now approaching a century old, and cracked pipes, dropped joints and root ingress give wipes, fat and debris plenty of places to snag.
The town’s water makes matters worse. Thames Water supplies Slough with very hard water, at roughly 299 mg/l of calcium carbonate, and over the years that scale lines the inside of waste pipes and drains. A bore already narrowed by limescale blocks far sooner than a clean one, which is why the same sink or soil pipe in an older Slough property can clog repeatedly.
Occupancy plays a part too. The borough council has consulted on licensing schemes taking in around 17,000 rented homes, more than 2,000 of them HMOs, and a shared house sends far more grease, hair and waste down one drain run than a single family would. Add the Salt Hill Stream and Chalvey Ditch catchments, both with a recorded history of surface water flooding, and gullies in north-west Slough can surcharge quickly after heavy rain. Everything eventually heads for the Thames Water treatment works at Wood Lane in Cippenham, but only if the pipes on your side are clear.
How we clear blocked drains
We start by finding where the blockage sits, then use the lightest method that will shift it. Drain rodding, from £80, deals with most straightforward blockages near an access point. Stubborn or greasy blockages get high-pressure water jetting at up to 4000psi, from £150, which blasts fat, scale and roots off the pipe wall so the blockage does not simply re-form around a punched channel.
If a drain keeps blocking in the same place, a CCTV survey from £120 puts a camera inside the run and pinpoints what keeps causing it, from a dropped joint to a root mass or a collapse. Emergency call-outs start from £120. All prices include VAT, and we agree the exact price with you before any work starts.
Slough blocked drain FAQs
Who pays to clear a blocked drain at my Slough rental property?
For licensed HMOs and other tenanted homes, keeping drainage and sanitation working is the landlord’s responsibility, though tenants can be liable if misuse caused the blockage. Our guide to who is responsible for a blocked drain explains where the boundaries fall, including shared and lateral drains.
Do you clear blocked drains at commercial units on the Trading Estate?
Yes. The estate has hosted food producers since Mars set up there in 1932, and kitchens and production units are classic sources of the fat and grease blockages that need jetting rather than rodding. We work around your operating hours to keep downtime short.
Why does my interwar Slough semi keep blocking in the same spot?
Repeat blockages at one point usually mean a defect in the original clay run, typically a dropped joint or roots. A CCTV survey pinpoints it so you can fix the cause once rather than paying for repeat clearances.
