Worktop replacement in Caledonian Road

Yes. Caledonian Road is on the patch, and the postcodes we work here are N7, N1. It is run from the Watford side, covering Hertfordshire & North London. 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. 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. It is a full day at the kerb, not a delivery. We template in your kitchen and fit in your kitchen, so there is nothing to visit and nothing to collect.

The structure below is commercial, so the floor is often timber over a shop ceiling and the load path under an island is worth thinking about. Post-war terraces have small, roughly square kitchens with a back door and a window in the middle of the run, so runs are short and joins are rare, but there are usually two corners and a window cill to work around in a couple of metres. What is under the old top is the real question. Internal kitchens with no window make dust control and extraction difficult, so cut off site wherever possible and bring the pieces in finished.

The road itself is narrow with bus lanes and peak-hour loading bans, and the estates behind have gated courtyards. Above-shop access is a single street door and a steep straight stair with no landing at the top to turn on. Sign-in at the gate, a permit on the dash and a named contact are usually wanted before anything comes off the van. 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. It sets what the day actually looks like. 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. The junction between the original room and the extension is the point to watch, because the two floors rarely sit at the same height. The carcasses have to be sound, because stone is several times the weight of what is coming off. A plumber either side of us. 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. Sound carcasses or it does not go ahead.

On a heavily veined stone the island and the run behind it are nested off the same area of slab so the movement relates across the room. The existing layout is being kept, so the question is whether the old carcasses will take stone in that shape without more support. 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 run can measure dead right at both ends and still belly out in the middle, which only appears once the laser plots the intermediate points. We would rather find it at template than on the morning, which is why the templater looks behind the units. Found at template, not on fit day. Empty the base units completely and have a plumber disconnect the sink, tap and any washing machine plumbed in under the worktop before we arrive. Where ownership is split across a building, the common parts belong to someone else and the carry route is negotiated rather than assumed. A replacement keeps the units and changes the surface, which is the least disruptive way to do this in an occupied property. Plumber either side of us.
