Splashbacks and upstands in Castelnau

Yes. Castelnau is on the patch, and the postcodes we work here are SW13. It is worked on our south west London run, along with the rest of Richmond upon Thames. Where the frontage is a clearway the unload happens away from the door and the carry gets longer, which is a crew and time question rather than a stone one. Splashbacks are normally the last thing off, so a short parking window is exactly when they get rushed. 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.

Walls are thick, lime-plastered and built in a soft brick, so they take a scribe well and take a fixing badly. Where a client wants a full-height piece behind the hob, it usually sits in the old chimney recess, and that recess is rarely square top to bottom or side to side, so it has to be templated as a trapezium rather than a rectangle. Cut from the same slab run as the tops. Tall rooms tempt full-height slab splashbacks, and at 2.4m plus these become the heaviest single piece on the job - plan the lift for the splashback, not the top.

The road is a busy artery towards the bridge with red-route style restrictions at peak, so unloading happens in the side turnings; villa front gardens are short with a flight of steps up to a raised entrance. A car that takes 2.4m on the diagonal will not take a three-metre worktop however it is stood, and there is no trimming it on the landing. Splashback panels are lighter than a worktop and far more awkward, because a tall thin piece has to be carried on edge and cannot be tilted to clear a turn. It decides panel size before anything is cut.

Yes. On the research for this patch it is the first of the three jobs listed, ahead of worktop fabrication and worktop installation. 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. The junction between the original room and the extension is the point to watch, because the two floors rarely sit at the same height. Ordered later from a different batch, the match is not reliable exactly where the pieces meet. Siliconed to the worktop, never grouted.

If the island is a few hundred millimetres longer than the usable length of a slab, a second slab gets bought to gain that overhang, and the whole slab is paid for rather than the part used. 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. Joint placement is a decision, not an accident. Material is £110-£550 per square metre supply only, and templating, fabrication and fitting are quoted on their own lines.

Legs bottoming out on hard concrete or an uneven screed mean the tops of the carcasses are not one plane, and that is picked up at template rather than on fitting day. 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. Make the wall good first, or accept the detail. The chimney breast recess must be replastered and fully dry, and the hob and extractor positions fixed, before anyone templates a full-height piece into it. A street with houses in single occupation next to the same houses cut into flats produces two completely different jobs from the same elevation. Splashbacks are cut from the same slab run as the tops, so they have to be decided before fabrication, not after. Same slab run as the tops.
