Worktop replacement in Crofton Park

Yes. Crofton Park is on the patch, and the postcodes we work here are SE4. It is worked on our south east London run, along with the rest of Lewisham. Without a bay the van ends up on a single yellow with a crew member watching it, which takes a pair of hands off the carry. We stage the strip-out so the old tops leave in one trip rather than trickling out across the afternoon. The waste run is planned, not improvised. We template in your kitchen and fit in your kitchen, so there is nothing to visit and nothing to collect.

The rear wall is usually a single brick thick and has been rendered, patched and re-rendered, so it bows in and out along the length of the run. 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. What is under the old top is the real question. Back-addition kitchens here are typically 1.8m to 2.1m wide, an island won't fit unless the rear wall has gone, and customers usually need telling that early.

Residential streets with permit bays and a narrow shopping parade on the main road; most houses have a front gate and short path, with side access only on end plots. 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. That is agreed before a plumber is booked.

Yes. On the research for this patch it is the first of the three jobs listed, ahead of worktop installation and worktop templating. 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 day, not a project. 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.

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.

Walls that bow along their length are the normal condition rather than the exception, and a straight-cut back edge will show a shadow gap at one end and touch at the other. 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. 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 replacement keeps the units and changes the surface, which is the least disruptive way to do this in an occupied property. Sound carcasses are the condition.
