Worktop replacement in West Green

Yes. West Green is on the patch, and the postcodes we work here are N15. It is worked on our north London run, along with the rest of Haringey. Permit hours are what matters, not the permit itself, because a bay that frees up at six in the evening is no use for a template at ten. 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.

Half-landings mean the back of the house sits at a slightly different level from the front, and a knocked-through kitchen crosses that line. Lath-and-plaster and bowed brickwork mean we template for scribes rather than straight cuts, and each piece is offered up and eased in rather than dropped straight down. Sound carcasses are the one condition. Flat-roof rear extensions here often have a shallow lintel over the garden doors - check the head height before planning a tall bank at the end of the run.

Flat streets, which is a relief after Crouch End, but they are narrow with permit bays both sides and speed cushions. Most houses have a side alley shared with the neighbour, gated at the front. A side gate and a back door mean the stone never goes through the house at all, which keeps the dust and most of the risk outside. With no room to turn, the old top gets cut up in the kitchen instead, which is dusty work and needs the room emptied first. The strip-out is planned around it.

Yes. On the research for this patch it is the first of the three jobs listed, ahead of worktop templating 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. The carcasses have to be sound, because stone is several times the weight of what is coming off. A day, not a project. 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.

Because a peninsula is seen from both sides, the underside of any overhang gets the same edge treatment as the top, which is easy to leave out of a spec. The existing layout is being kept, so the question is whether the old carcasses will take stone in that shape without more support. Height change is checked before we cut. Material is £110-£550 per square metre supply only, and templating, fabrication and fitting are quoted on their own lines.

A low sill over the sink run is what decides between an upstand and stone dying into a window board, and there is often less clearance than an upstand is tall. The old top has been hiding it, so the first honest look at it happens when the laminate comes off. It is the usual surprise, and it is a known one. Have a plumber booked to disconnect the sink, tap and waste first thing and reconnect after we have gone, and clear the hallway and stairs completely so we can carry slabs through the house. 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. A plumber disconnects before we arrive and reconnects after we leave, and that is worth booking early. Units kept, surface changed.
