Worktop replacement in Roxbourne

Yes. Roxbourne is on the patch, and the postcodes we work here are HA2. It is worked on our north west London run, along with the rest of Harrow. A dropped kerb wide enough for a car is not always wide enough for a long-wheelbase van, and the width of the crossing decides the rest. 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. A suspension for the full day beats half a day lost. You never have to visit anything or collect anything: we template in your kitchen and fit in your kitchen.

The hot water cylinder sits in a cupboard opening off the kitchen or the landing above it, and the pipework to it drops through the corner of the room. Ex-council flats and maisonettes are built in dense concrete and blockwork, so anything that has to be fixed back, such as brackets under a peninsula or support for an end panel, goes in with proper anchors and an SDS rather than plasterboard fixings. The old top hid it; the new one will not. Anything that has to stay accessible, a stopcock, a gas meter, a riser panel, is marked on the template so the stone is cut around it instead of over it. This is the commonest reason a replacement turns out to need more than a straight swap. Found at template, not on fit day.

The side passage is the measurement that matters, because a piece has to be carried flat down it and then turned in at the back door, and the turn is always tighter than the passage. Worth remembering that the old tops have to come out the way the new ones come in, and a laminate run is easier to remove in one length than to carry in one. Timing the two carries is most of the planning. Where a car has to come off the drive first, it is worth knowing whose car it is and whether the keys are in the house on the morning. 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. Nothing goes out until the route back to the van is clear.

Yes. On the research for this patch it is the first of the three jobs listed, ahead of worktop installation. Extension work runs late far more often than it runs early, and the worktop is close to the last thing in, so the date agreed at the start is rarely the date that happens. The carcasses have to be sound, because stone is several times the weight of what is coming off. Chosen against the doors that are staying. Where a family has been living around a building site for months, the finish date carries more weight than any other part of the specification. Old tops out in the morning, new stone down and sealed the same afternoon. Old top out Tuesday, tenant in on Friday.

Butt-jointing over the gable puts the seam a few hundred millimetres back from the corner, below the eye line instead of straight across it. The existing layout is being kept, so the question is whether the old carcasses will take stone in that shape without more support. Old runs are rarely square, and stone will not forgive it. Supply only, material is £110 to £550 per square metre, with templating, fabrication and fitting quoted on their own lines.

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. We would rather find it at template than on the morning, which is why the templater looks behind the units. It is the usual surprise, and it is a known one. Sort a parking bay or permit near the entrance, confirm the lift is in service and get us the door codes, and tell us about any asbestos survey on the flat before we start stripping out. These kitchens tend to be compact and reasonably square, so the fixed template, fabrication and fitting lines are a larger share of the total than the stone is. A replacement keeps the units and changes the surface, which is the least disruptive way to do this in an occupied property. Owners phase this work; a void period cannot.

Cut-outs, edge profile and join count are itemised, so taking one out removes a line rather than starting an argument. Material is quoted supply only and templating, fabrication and fitting sit on their own lines, so it is visible which part is stone and which is labour. 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. A laminate top was scribed thin at the back to swallow it, and stone cannot be shaved down the same way. It was there long before we were.

Where the hob lands is set out against the units and the wall behind, not off the kitchen plan. A piece with a bowl and a hob cut into it is the fragile one, and it is handled accordingly. Undermount bowls are cut and polished in the workshop and dry-fitted to the stone on the bench before anything is loaded. Corner sinks and corner hobs sit exactly where the joint wants to be, so on an L the cut-out positions get settled before the join positions do. Old laminate has often been holding a run square for years, and taking it off shows what the units were really doing. Where the seam went before is not where it goes now.

The same firm templates and fits. Nobody else is brought in to install. Upstands and splashbacks are templated after the worktop is down and settled, so they are a separate visit. The template is taken in your kitchen after the units are in and fixed, never before. Windows sit in deep concrete reveals with a cast sill, and that reveal is usually the least square thing in the room. The units stay and only the surface changes, so the job is a day, and what makes it a difficult day is the building. Stone is far heavier than what is coming off.

Slabs come in finite sizes, so a long run needs a join whatever the room looks like. Dark and heavily veined stone shows a join more than a pale even one, which is worth knowing before the slab is picked. Join count and position are settled from the template drawing rather than improvised on the fitting day. One leg of an L is nearly always the working run and the other little more than a landing space, but both are templated, cut and edged to the same standard. Going from a 38mm laminate to 20mm or 30mm stone drops the surface, which shows against tiles, a window board and any freestanding appliance. Stone wants gables where laminate needed none.
