Worktop replacement in Swiss Cottage

Yes. Swiss Cottage is on the patch, and the postcodes we work here are NW3, NW6. It is worked on our central and north London run, along with the rest of Camden. Loading exemptions on red routes are narrow, time-limited and heavily camera-enforced, so we plan around them rather than relying on them. A replacement is a two-way job, with old tops going out and new stone coming in, so the van needs to stay put across the whole day. 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. A full stone piece is several times the weight of the laminate coming out, and there is rarely room to turn it on a half-landing. Units kept, surface changed, one day. Interwar block kitchens sit on a solid concrete floor with a boxed-in soil stack in the corner, so allow for a notch and a scribe rather than assuming a clean 90-degree return.

Finchley Road is a red route with no stopping, so loading happens on the side streets under a Monday to Friday CPZ. Most blocks have a lift, but the older 1930s cars are small and shallow and a 3m slab will not stand up inside one. 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. We plan the strip-out and the carry as one movement so the kitchen is only out of use for a single day. It sets what the day actually looks like.

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

Two parallel runs with a walkway between them is the most efficient shape there is on a slab, because both pieces nest as straight lengths with almost no waste. 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 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. The old top has been hiding it, so the first honest look at it happens when the laminate comes off. Found at template, not on fit day. 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. A plumber disconnects before we arrive and reconnects after we leave, and that is worth booking early. Plumber either side of us.
