Ask a Windsor homeowner why they have put off booking a jetter for a sluggish drain and the same worry surfaces again and again: won’t that much pressure wreck pipework this old? It is a fair question in this town. The houses along Church Street date largely from the late 1600s and early 1700s, the Guildhall was finished in 1689, and the cobbles of Queen Charlotte Street, at under sixteen metres reputedly the shortest street in Britain, have outlasted every drain ever laid beneath the town centre. Plenty of those drains are still in service, in clay or brick, and they deserve some respect.
TrueFlow provides drain jetting across Windsor with that question taken seriously. We are a Bracknell-based drainage firm, fully insured, working 24 hours a day, 365 days a year, with a 60-minute response target for emergencies and a 6-month guarantee on our work.
Will high pressure damage old drains?
Honestly: it can, if it is applied carelessly, which is exactly why we never apply it carelessly. A jetting unit is not one fixed blast. Our equipment works at up to 4000psi, but that figure is a ceiling, not a default, and the engineer sets the working pressure after weighing up the age, material and condition of the run in front of them. A sound modern plastic pipe will happily take far more force than a century-old clay one with open joints, so the two are never treated the same. Nozzle choice matters as much as pressure, and a small number of materials, pitch fibre among them, call for gentler methods again.
Where a drain’s condition is unknown and the house is old enough for doubt, we put the camera in before the jet. A CCTV drain survey in Windsor shows us what the pipe is made of and where its weak points sit, and the combined jet-and-survey visit starts from £220 including VAT. On a fragile run, ten minutes of footage is what separates a controlled clean from an expensive mistake.
The cheapest conservation work a period house gets
For owners of listed and conservation-area property, the outcome to avoid is excavation. What usually pushes a stable old drain towards that fate is not the jetting; it is the years of grease, scale and silt that keep waste water standing in the pipe, soaking every weak joint and washing out the ground beneath. Clearing that build-up under controlled pressure, before it does structural harm, is routine maintenance that helps an elderly drain stay an elderly drain rather than become a rebuilding project under someone’s Georgian frontage.
When jetting is the right call
For a one-off soft blockage, rodding from £80 is often the sensible first move. But rods only deal with what stands in the way; the grease and scale bonded to the pipe itself stay behind, and the drain narrows back to trouble within weeks. A jet works on that lining directly, lifting deposits off in layers and flushing them on towards the sewer, so the pipe goes back to the diameter it was laid with. That is why jetting is the answer for drains that block repeatedly, for kitchen runs behind cafés and guest houses, for silted gullies, and for root ingress at old joints, where a cutting nozzle clears the growth without a spade going anywhere near the garden.
