Worktop replacement in St Luke's

Yes. St Luke's is on the patch, and the postcodes we work here are EC1V. It is worked on our north London run, along with the rest of Islington. 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. Waste is the part people forget: the old laminate or tired granite has to be walked back to the van and it does not get lighter. Old tops out and new stone in, both through the same gap. 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. The lift car is usually too short and too low to take a full-length piece flat or on edge, so stone either goes up the communal stairs with their half-landings and winders, or the run is designed with joins that suit the staircase rather than the kitchen. Units kept, surface changed, one day. 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. Weight tells on a staircase more than anywhere else, because there is nowhere to set a piece down mid-flight and no way to change your grip once it is moving. We plan the strip-out and the carry as one movement so the kitchen is only out of use for a single day. That is agreed before a plumber is booked.

Yes. On the research for this patch it is the first of the three jobs listed, ahead of worktop splashbacks & upstands and worktop installation. 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. The units stay and only the surface changes, so the whole job is one day rather than a kitchen refit. A day, not a project. A new extension slab is not automatically level, and that wants checking before templating rather than after the stone is cut. Old tops out in the morning, new stone down and sealed the same afternoon. A day, not a project.

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. Going from a 38mm laminate to 20mm or 30mm stone drops the surface, which shows against tiles, a window board and any freestanding appliance. The units stay, the surface changes. Material is £110-£550 per square metre supply only, and templating, fabrication and fitting are quoted on their own lines.

A boxed soil stack or service riser in the corner of a run eats into the worktop depth and has to be scribed around rather than cut square. The old top has been hiding it, so the first honest look at it happens when the laminate comes off. The laminate has been covering it up. Get the managing agent's or freeholder's approval and the permitted hours confirmed beforehand, and agree with the porter who protects the communal carpet, stonework and lift. 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. If the carcasses are tired the honest answer is that stone will find that out, and it is better said before than after. Units kept, surface changed.
