Worktop replacement in Green Street Green

Yes. Green Street Green is on the patch, and the postcodes we work here are BR6. It is worked on our south east London run, along with the rest of Bromley. Gravel and block paving both look like hard standing and neither takes a loaded trolley, so the run from tail lift to door gets boarded. 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. We come to the kitchen to template and again to fit, so there is nothing to visit and nothing to collect.

Base units from the seventies and eighties are often only 500mm deep, so a 600mm stone top overhangs at the front and the doors want checking against it. 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. Sound carcasses are the one condition. A wall line that runs level over a floor that does not means the finish closes up on the plinth at one end, which is joinery rather than something the stone can answer. The old top has been hiding it, so the first honest look at it happens when the laminate comes off. A straight swap is the exception in an older room.

The van gets close to the door and the stone comes off the tail lift onto a trolley, which is about the shortest carry we ever get. 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. Waste goes out the way the stone came in, so the route stays clear. A shared drive is only useful if the neighbour is not the one parked behind the van, so we ask which side the standing belongs to before the date is set. 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. The old tops have to go somewhere as well.

It sits second or third on this patch, behind worktop installation. Same template visit, same benches, same installers either way. Kitchens go in near the end of a conversion, behind the plastering and the flooring, by which point the programme has already absorbed whatever slipped earlier. The units stay and only the surface changes, so the whole job is one day rather than a kitchen refit. Specified for wear rather than for the photograph. Studio and one-bed conversions put the whole kitchen against a single wall, so the job is one run and everything depends on that one length. The carcasses have to be sound, because stone is several times the weight of what is coming off. No sealing schedule for anybody to forget.

The return piece is the awkward one on a slab: short, full depth, and rarely nesting neatly against the long lengths, so yield rather than area is what moves the material figure. The existing layout is being kept, so the question is whether the old carcasses will take stone in that shape without more support. Carcasses have to be sound first. The material band is £110 to £550 per square metre supply only, and templating, fabrication and fitting are quoted on their own lines.

Where two pieces meet over a fall in the floor the join has to be flush to the hand as well as true to the level, because the eye reads the join and forgives the room. This is the commonest reason a replacement turns out to need more than a straight swap. The wall has not moved, and neither has the problem. 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. The householder is normally on site at template, and that is the right time to settle sink position, tap centres and overhang rather than agree them by email. A replacement keeps the units and changes the surface, which is the least disruptive way to do this in an occupied property. Void periods do not extend to suit a lead time.

The tap and waste have to be disconnected by a plumber before we start and reconnected once the stone is in. Tiling bonded to the wall behind usually comes away with the old top, so that wall is agreed beforehand. Carcasses stay. Surface changes. That is the whole of it. Drives with a dropped kerb and a tight turn-in take a long van at an angle, and that angle decides which side the tail lift can work from. We stage the strip-out so the old tops leave in one trip rather than trickling out across the afternoon. Access out counts as much as access in.

Granite is porous to varying degrees, so it is sealed when we fit it and topped up over the life of the worktop. Quartz and sintered stone never need sealing: quartz is non-porous and sintered stone has effectively zero porosity. A seal is not waterproofing. It only buys time to wipe a spill up. The kitchen is at the front or the back depending on the plan, and which it is decides whether there is a rear door on the route at all. Chipboard carcasses under the sink swollen from a slow leak will not take stone and get replaced before fit day. Off in the morning, on by the afternoon.

An island is where this usually shows, standing free with no wall to level against. If the carcasses are corrected, the template is taken again, since a drawing off units that then moved is worthless. Where a run meets an appliance, level decides whether that appliance door still clears the stone above it. Floors settle, and once base units are packed and levelled properly the stone sits true while everything else in the room admits it is not. We would rather find it at template than on the morning, which is why the templater looks behind the units. Packing the carcasses is part of the replacement.

A full-height piece shows a wall that is out more than an upstand does, over the extra height. Socket and switch positions have to be final before templating, because the openings are machined rather than chopped out on the wall. These were built on a solid ground floor slab, so nothing bounces and nothing can be packed down, only up. The two corners and the cill in a couple of metres are all re-measured once the old top is off. The old top hid it; the new one will not.
