Splashbacks and upstands in St Luke's

Yes. St Luke's is on the patch, and the postcodes we work here are EC1V. It is run from the Watford side, covering Hertfordshire & North London. A red route means no stopping, and no stopping means exactly that, so the stone comes in from a side street or from a bay behind the property. Panels come off the van in one trip where possible, since a tall piece handled repeatedly is a piece asking to be chipped. Handling is where these pieces get damaged. We template in your kitchen and fit in your kitchen, so there is nothing to visit and nothing to collect.

Inter-war purpose-built blocks have curved external walls and steel windows, so a run along an outside wall is following a genuine curve rather than a bow. Boxed risers break the run into returns, and every return is a separate piece with its own mitred corner. Decided before fabrication starts. Stone stairs and iron rails mean corner protection on every turn, since a chipped edge on the way up is the most common loss on these blocks.

Old Street and City Road are red routes, and the estates have courtyards with bollards and narrow arched entries built for handcarts rather than vans. The older blocks are walk-ups with stone stairs and iron balustrades that do not forgive a swung slab. Communal stairs get boarded and the handrail padded, and we walk the route with a tape before the first piece leaves the van. It is usually the full-height panels rather than the tops that will not make the turn, and that only shows up when they arrive. It decides panel size before anything is cut. Tell us what the approach looks like when you book the template and it gets built into the day rather than discovered on it.

It is one of the three we do most here, behind worktop replacement. Same template visit, same workshop, same installers either way. A new extension slab is not automatically level, and that wants checking before templating rather than after the stone is cut. Splashbacks and upstands are cut from the same slab run at the same time, which is the only way the batch actually matches. Same batch, same run, same day. Extension kitchens are usually specified long before they are buildable, so the run lengths on the drawing and the run lengths in the room are different numbers. Ordered later from a different batch, the match is not reliable exactly where the pieces meet. Same batch, same run, same day.

The catch with a galley is that both runs are seen end-on from the doorway, so any difference in overhang between the two reads immediately. The same shape decides where splashback pieces break, and a joint in a corner reads as a detail while one in a clear run reads as a mistake. Corners get their own pieces. Material is £110-£550 per square metre supply only, and templating, fabrication and fitting are quoted on their own lines.

A notch around a boxed stack is machined with a radius at the internal corner, because a square inside corner there is exactly where a top will crack. It is usually what pushes a job towards a 100mm upstand instead of a full-height panel, because an upstand rides what a panel exposes. Scribed, dubbed out, or set proud. Pick one. The riser boxing must be finished in its final form and any access panel positions agreed before the template, since the stone is set out around them. The same building type can arrive as a careful one-off kitchen or as a fast turnaround, and the honest answer is that they are priced differently. Splashbacks are cut from the same slab run as the tops, so they have to be decided before fabrication, not after. The wall has to be ready.
