Worktop replacement in Loughborough Junction

Yes. Loughborough Junction is on the patch, and the postcodes we work here are SE5, SW9. It is worked on our south London run, along with the rest of Lambeth. A van waiting on a loading concession has somebody standing with it, because a vehicle left unattended is the one that collects the ticket. 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. Two loads, one space, one day. The measuring and the fitting are both done at the property, so there is nothing to visit or 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 mansion block is a logistics job before it is a stone job. The building has kept moving; the new template catches up. 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. This is the commonest reason a replacement turns out to need more than a straight swap. Levels get corrected before the new top is measured.

Garden routes carry their own hazards: a drain cover, a step up to a patio, wet decking, or a lawn that will not take a loaded trolley. 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. Old pieces are carried out before new ones are carried in. Controlled hours that end in the middle of the afternoon make the second half of the day easy and put the whole problem in the first half. We stage the strip-out so the old tops leave in one trip rather than trickling out across the afternoon. The old tops have to go somewhere as well.

Yes. On the research for this patch it is the first of the three jobs listed, ahead of 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 carcasses have to be sound, because stone is several times the weight of what is coming off. The annexe top goes in on the same day. 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. Booked at short notice, because the notice is short.

If the island is a few hundred millimetres longer than the usable length of a slab, a second slab gets bought to gain that overhang, and the whole slab is paid for rather than the part used. The existing layout is being kept, so the question is whether the old carcasses will take stone in that shape without more support. Appliance gaps are checked against the new thickness. Supply-only material is £110 to £550 per square metre, and templating, fabrication and fitting are quoted separately rather than rolled in.

A live soil stack cannot be chased back into the wall, so the depth it steals is permanent and the run is planned around it rather than through it. We would rather find it at template than on the morning, which is why the templater looks behind the units. Same footprint, different tolerances. 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. A street with houses in single occupation next to the same houses cut into flats produces two completely different jobs from the same elevation. A replacement keeps the units and changes the surface, which is the least disruptive way to do this in an occupied property. The surface changes and the kitchen stays the one they know.

Machining is permanent. If a later kitchen moves the sink, the grooves stay where they were cut. A groove set needs a clear stretch of worktop beside the bowl, so it competes with the run for length instead of being free surface. Where there is no room for a separate drainer, grooves are usually what gets specified instead. This is a logistics job before it is a stone job, and the lift car is usually the single biggest constraint on the design. The units stay and only the surface changes, so the job is a day, and what makes it a difficult day is the building. The old top is heavy waste, and booked as waste.

The lift, if there is one, is measured on the diagonal, because that is the dimension a long piece actually uses. What decides it is not the width of the stairwell but the length of piece that can be turned in it. The alternative to a join is a shorter run, which is usually the wrong thing to trade away. A side gate hung to open outward against a fence post is narrower in use than it measures, and lifting the gate off its hinges is usually the quickest win on the route. We plan the strip-out and the carry as one movement so the kitchen is only out of use for a single day. Half a day can go on the strip-out where the way in is tight.

If the carcasses are corrected, the template is taken again, since a drawing off units that then moved is worthless. Packing takes up small variation. It is not there to hide something that belongs in the units. Units have to be fixed down as well as levelled. A loose carcass moves under stone. Boxing built in plasterboard on a light frame will take no useful fixing, so nothing bears on it and the stone is carried off the carcasses either side. A laminate top was scribed thin at the back to swallow it, and stone cannot be shaved down the same way. The sill was always low. Nobody had to care until now.

Slabs come in finite sizes, so a long run needs a join whatever the room looks like. A mitred join at a corner is a different job from a butt join along a run, and they are not priced the same. Veining carries through a join where both pieces come off the same slab, which is decided at nesting. 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. Old laminate has often been holding a run square for years, and taking it off shows what the units were really doing. The island top is the one that may want its own slab.
