The Victorian and Edwardian terraces and villas in Linslade. The London and Birmingham Railway arrived in 1838 and a new settlement grew up south of Old Linslade, first called Chelsea New Town. That is where most of the town’s nineteenth century stock sits. The bathroom is very often a later addition over a scullery or in a back extension, which brings three things with it: shallow roof pitches over the room, cold external walls, and a waste run that has been extended more than once by more than one person. We normally replace the whole waste arrangement rather than tee into somebody else’s improvisation, and we insulate those external walls while the boarding is off.
The 1970s estates, where Linslade doubled in size. Modern enough to be straightforward structurally, old enough that the heating pipework is often 8 mm or 10 mm microbore and the cylinder is a single feed indirect. If you are adding a heated towel rail or moving radiators as part of the refit, that pipework needs looking at honestly rather than being teed into and hoped for.
The High Street, the Market Cross and the streets around All Saints’ Church, which dates from 1277. This is the Leighton Conservation Area, reference CA51, designated by Central Bedfordshire Council. If a building is listed, altering internal fabric can need consent in its own right, and a new soil and vent pipe or a new external waste run on a visible elevation is a conversation to have with the council before the tiles are ordered. We flag it at survey.
The eastern and southern urban extensions. Modern plastic pipework, sensible joist depths, soil stacks where you would expect them. The jobs here are usually en suite upgrades and turning a builder’s standard bathroom into something better. The constraint is almost always the fall on the new waste run, not the structure.
Anything backing onto the canal or the Ouzel. Those plots sit low, and ground floor damp in a bathroom on that side of town is not automatically a plumbing leak. We check before we start ripping out, because replacing a bathroom will not fix groundwater.
