Splashbacks and upstands in Castelnau

Yes. Castelnau is on the patch, and the postcodes we work here are SW13. It is run from the New Malden side, covering South West London & Surrey. 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. That is why they are crated the way they are. We template in your kitchen and fit in your kitchen, so there is nothing to visit and nothing to collect.

Rooms are tall with deep window reveals, and a run finishing into a reveal is templated to it rather than assumed square. Lath-and-plaster on the party wall and the chimney breast returns almost never runs true, so a 100mm upstand bedded on silicone is the honest answer here — it rides the bow and hides the junction the worktop can never close on its own. The wall makes that decision, not the brochure. 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. The lift has to be booked and blanketed before anything moves, and that booking needs to cover the old tops coming out as well as the new stone going in. 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. Joint positions follow from that. Tell us what the approach looks like when you book the template and it gets built into the day rather than discovered on it.

Yes. On the research for this patch it is the first of the three jobs listed, ahead of worktop fabrication and worktop installation. 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. Socket and switch positions have to be final before templating, because a cut-out in the wrong place means a new piece. Sockets final before template. Rear and side-return extensions are where the islands appear, and an island is the piece that decides whether one slab does the kitchen or two. Socket and switch positions have to be final before templating, because a cut-out in the wrong place means a new piece. Same batch, same run, same day.

An island is a single visible piece with four finished edges and no wall to hide against, so it is the piece the whole kitchen is judged on. Upstands follow the run exactly, so every internal and external corner is a separate mitred or butted piece. 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.

Floors settle, and once base units are packed and levelled properly the stone sits true while everything else in the room admits it is not. A tall panel that fits at the worktop will stand off the wall at the top unless the wall is dubbed out or the panel is scribed. An upstand rides what a panel exposes. 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. Mixed ownership means the decision-maker is not always the person who lets us in, so it is worth being clear early about who signs the quote off. Full-height panels need the wall made good first, which is another trade and another timescale. Decided before fabrication, not after.
