A blocked drain never picks a good moment, and in Reading it tends to strike the properties least able to cope: century-old terraces off the Oxford Road, busy shared houses near the university and low-lying homes by the rivers. TrueFlow provides 24/7 blocked drain clearance across the whole town, from RG1 out to Tilehurst, Caversham and Whitley.
We are based in Bracknell, a short run up the A329(M), and we aim to be with Reading emergencies within 60 minutes. Every visit is covered by our 6-month guarantee, we are fully insured, and you approve an exact price before any work starts.
Why drains block in Reading
Reading grew fastest during its biscuit-town years, when rows of brick terraces went up around the Oxford Road, East Reading and Caversham to house Huntley & Palmers workers. Beneath those streets, many of the original clay drainage runs are still in service. The shrinkable London Clay under much of the town moves with wet and dry seasons, easing pipe joints apart so tree roots creep in and wipes, grease and scale snag on the damaged sections.
The rivers add a second layer of trouble. Reading sits where the Kennet meets the Thames, and in January 2024 the Thames here rose to its highest level since 1947. When river and groundwater levels climb, gullies and older drains around Lower Caversham and the Kennet-side streets surcharge, and a partial blockage that went unnoticed all summer suddenly floods a yard.
Even the public sewers feel the strain. Thames Water closed West Street in the town centre in May 2022 to repair a collapsed sewer, and a further sewer collapse in Caversham shut a road for weeks of repairs in 2023. Add tap water classed as hard to very hard from Thames Water’s chalk-fed supply, which coats waste pipes in scale, and Reading’s drains have plenty working against them.
How we clear blocked drains
Most blockages go with drain rodding, from £80. Stubborn grease, roots and compacted wipes get high-pressure water jetting at up to 4000psi, from £150, which cleans the full bore of the pipe back to the clay instead of leaving a narrow channel that soon blocks again. If a drain keeps blocking, a CCTV survey from £120 shows us the cause on screen, whether that is root ingress, a displaced joint in Victorian clay pipework or a partial collapse. Emergency call-outs start from £120. All prices include VAT, and we agree the exact figure with you before touching a drain.

Reading blocked drain FAQs
Who pays when a shared drain blocks behind a Reading terrace?
Many terraces in East Reading and off the Oxford Road still drain into shared rear runs. Once a drain carries waste from more than one property, it is usually a lateral drain or sewer that Thames Water must maintain, so the fix may cost you nothing. Our guide to who is responsible for a blocked drain explains how to tell.
I manage an HMO in Reading. Can you help quickly?
Yes. Reading has around 3,000 HMOs under Reading Borough Council licensing, and a blocked shared kitchen or bathroom stack affects every tenant at once. We attend 24/7, agree the price with you by phone before starting, and guarantee the work for 6 months.
My drains gurgle and back up when the Thames is high. Is that normal?
It is common in low-lying parts of Caversham and near the Kennet. High river and groundwater levels fill older drains from below, so any partial blockage shows itself. Jetting the run clear before winter gives high water nowhere to catch.
