Farnham is the town below the castle, and the castle is the least deceptive thing in it. Down in the streets, the dates carved on the buildings are not to be trusted: the pediment on 3 Downing Street says 1717, yet the frame behind it is older, and Historic England records the same pattern through the centre, from the late 18th-century front on 6 and 7 The Borough wrapped around a timber-framed core to the 16th-century Vernon House on West Street, refaced in the early 18th century. Farnham rebuilt its faces in brick when the hop trade made it rich, and the rebuilding stopped at the faces.

Two building dates, one set of pipes
That gap between front and frame matters to anyone running water through these buildings. On Castle Street or The Borough, the floor levels, voids and cellar stairs behind a Georgian front can belong to a 16th-century structure that follows no later logic, so a single supply may step up, drop down and change material three times between the main and the kitchen tap. Plumbing repairs here begin with the building’s biography: identify which era the fault sits in, and the right place to open up usually follows from that answer. Much of the centre is listed or within the conservation area designated in 1970, so alterations that would disturb historic fabric belong in a conversation with Waverley Borough Council before they belong on a job sheet.
The old core also works in three dimensions. Behind the street fronts run the yards and passages Farnham is known for, Lion and Lamb Yard through its archway off West Street and Borelli Yard off The Borough among them, and a repair in the buildings around them is a question of access as much as plumbing: where the van can stand, how far hoses must be carried, which hatch or coal plate reaches the pipework in question.
The pipework below the pavement
Listed-building records spell out the other Farnham habit: cellars. The entry for 9 Castle Street describes two storeys with attic and cellars; 86 and 87 West Street are recorded as two storeys and cellar. A cellar is the coldest place in any house, and in Farnham it is frequently where the plumbing starts: the incoming main rising below street level, a stop valve seldom visited, and sometimes a surviving run of lead entering below ground exactly where nobody looks. Unlagged pipes at that level meet freezing conditions the rooms above never feel, so cellar pipework deserves insulation, a working stop valve, and an occasional check of the oldest metal down there; where lead is found, replacement is quoted plainly and the choice stays with the owner.
Below-ground rooms also complicate waste, since a sink or appliance at cellar level can sit lower than the drain it must reach, which calls for a pumped connection, far cheaper to design in than to retrofit. The levels matter outdoors too: until the 1960s the Wey regularly flooded as far as halfway up Downing Street before the banks were widened, and the lower streets remain the bottom of the town’s drainage, where sound gullies and underground pipework matter most.
A damp cellar is not automatically a plumbing failure; ground moisture and condensation produce the same look. A pressure test on the supply and a check of the visible runs will rule the plumbing in or out quickly, and quotes for leak detection are free.
Ground that was good enough to fire
Farnham’s historic core sits on gault clay and upper greensand, and the clay was good enough to build an industry on: the Farnham Pottery at Wrecclesham, founded by Absalom Harris in 1873 and run by five generations of his family until 2000, dug its own claypit and fired the local gault into green-glazed ware that sold through London department stores. The buildings are Grade II listed now, among the best-preserved Victorian country potteries in England.
What fires well behaves badly around buried pipes. Clay swells when wet and shrinks when dry, and that seasonal movement works on rigid clayware drains year after year, opening joints and pushing sections out of line until flow slows and roots find the gaps. The pattern shows up as a drain that blocks repeatedly in the same place, and the economical response is to see the pipe rather than keep clearing it: a CCTV survey from £120 inc VAT shows the joints as they actually are, so drainage repairs can be priced against evidence. Where the immediate problem is a blockage, rodding starts from £80 and jetting from £150, and unblocking is No Fix No Fee: if the pipe turns out to have collapsed rather than blocked, the charge is for the survey and diagnosis, not the clearing.
Heath End, Hale, Wrecclesham and Badshot Lea
Most Farnham plumbing does not involve a listed frame or a cellar. The villages the parish absorbed, Heath End on the Aldershot boundary, Hale and Weybourne above the river, Wrecclesham and Badshot Lea, carry the ordinary 20th-century stock where jobs are quicker: accessible pipework, standard fittings, and faults that match the fixtures’ age rather than the building’s. Heath End grew with the army camp next door at Aldershot. Taps, cylinders, ball valves, overflows and tired stop taps across these streets are everyday work, covered by the same 6-month guarantee as everything else.
Farnham prices before the work, not after
All prices include VAT and the exact figure for the job is agreed first:
- Drain rodding from £80
- High-pressure jetting from £150 (up to 4000psi)
- CCTV drain survey from £120
- Jetting plus CCTV survey from £220
- Emergency call-out from £120
Leak detection has no fixed starting price because every search differs, so those quotes are free. The complete list is on the pricing page.
Farnham plumbing and drainage questions
How do I stop cellar pipework in Farnham freezing?
Lag it, and make sure the stop valve works before winter rather than during it. A cellar is below the warmth of the house, so pipes at that level freeze in weather the living rooms shrug off; foam insulation on every accessible run plus a stop valve that turns freely gives you prevention and a fast shut-off if a pipe does split.
Is it safe to run new plumbing through a timber-framed Farnham building?
Yes, when the route is chosen to suit the frame rather than imposed on it. Historic timber is the one part of the building that cannot be replaced, so new pipework goes where the structure offers space and stays clear of what holds the house up; a run placed that way is also easier to get at next time.
Which company supplies Farnham’s water, and who takes the wastewater away?
South East Water supplies the tap water, and has recently invested in new mains serving the town, including a scheme laid partly along West Street. Thames Water is the sewerage undertaker for Farnham, so shared sewers beyond your boundary are reported to Thames Water, while drains serving only your property are the owner’s responsibility, which is where we come in.
Why does the same drain in Farnham keep blocking?
Usually because clay ground has moved the pipe, not because of what goes down it. Shrink and swell in the local clay displaces joints in older rigid drains, and every displaced joint is a ledge that catches waste in the same spot. A CCTV survey from £120 shows whether the run needs a repair, and a repair priced from camera evidence ends the cycle of repeat clearances.
Does TrueFlow cover the villages around Farnham?
Yes. Wrecclesham, Hale, Weybourne, Heath End, Badshot Lea and the GU10 villages are covered on the same terms as the town centre: 24/7, 365 days a year, with the exact price agreed before work begins.
