Flooded cellar in Ilkley

First response (the wet day)

If the cellar is in water now:

1. Electricity — if water is near sockets, a consumer unit in the cellar, or a pump already sitting in the wet, treat it as unsafe. We are not an emergency electrician.
2. Stop adding water — a downpipe emptying into the light well, a blocked gulley on the downhill area, washing-machine discharge into the room, a burst in the kitchen above. Plumbing leaks are not Type C, and a silted light-well drain is not a “high water table”.
3. Pump-out — a wet vac may clear a film on flags. A tanker on Wells Road or Queen’s Road is steep, neighbour-sensitive, and not a Grove parking bay. Say so if you think you need one; do not assume we can sit a lorry on the conservation grid.
4. Do not hack off lime plaster as a panic move, and do not paint cement slurry onto wet millstone grit “to seal it”. That coat is how Ilkley cellars already fail.
5. Photograph the high-water mark on the gritstone, the light-well reveal, and the downhill corner. Those marks are evidence for the later survey.

Ilkley Cellar Waterproofing is not a 24/7 flood-restoration franchise. If you need a same-day pump-out, say so on the phone. The waterproofing specification still waits until we can see the empty room.

What “moor runoff in a hillside cellar” usually means here

Rombalds Moor sheds into Backstone Beck, Hebers Ghyll, Spicey Gill and the cuts through Panorama Woods. After rain on the Cow and Calf side, that water is already moving downhill before it meets a cellar wall. Typical patterns on this stock:

• Film after rain on the moor at the light-well reveal of a Wells Road / Queen’s Road / Parish Ghyll villa — perched water in the grit, not a valley water table.
• Light well holding water on a stepped plot that drops toward The Grove or the river, with a gulley that silted or was never connected.
• Seepage through millstone grit that a previous cement coat tried to seal, then blew.
• Middleton / Bridge Lane / riverside only: Wharfe-side groundwater — a different question, asked only when the house is actually there. Do not copy the hillside story onto those plots, and do not copy a Wharfe story onto Wells Road.

It is not canal overtopping, not Worth Valley floodplain, not Alwoodley Beck under King Lane.

If every wet week on the moor repeats the same puddle, first response is not enough. That is the Type C conversation: tanking a cellar on millstone grit, Type C that leaves the stone elevation alone.

Full waterproofing is the second job

A flooded cellar that dries and never returns may only have needed the light-well gulley clearing or a downpipe moved off the area. A flooded cellar that returns after rain on Rombalds Moor is a candidate for cavity drain and a sump whose discharge does not become a spring on the downhill garden toward the town.

The discovery survey is booked once you can get into the room. Cost sits on the cost page as ranges, not a flood-day guess.

Conversion talk waits until it is dry. After waterproofing.
