Worktop replacement in Whetstone

Yes. Whetstone is on the patch, and the postcodes we work here are N20. It is worked on our north London run, along with the rest of Barnet. 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. Two loads, one space, one day. There is nothing to drive to and nothing to pick up, because both visits are to the property itself.

Floors are concrete with a screed and a thin finish, so there is no give anywhere and packing the carcasses is the only way to get a plane. A mansion block is a logistics job before it is a stone job. Old tops were scribed to a wall that has moved since. 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. The old top has been hiding it, so the first honest look at it happens when the laminate comes off. The beading was covering a bowed wall.

Standing a three-metre length on end takes more headroom outside the car than inside it, and a low lobby ceiling is what actually stops it. 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. It decides whether the old top leaves whole. Where the frontage is a clearway the unload happens away from the door and the carry gets longer, which is a crew and time question rather than a stone one. 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. Extension budgets are usually well spent by the time the worktop is ordered, which is where the choice between quartz and a thinner sintered stone actually gets made. The carcasses have to be sound, because stone is several times the weight of what is coming off. A builder-finish kitchen upgrades in a morning. 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. Old tops out in the morning, new stone down and sealed the same afternoon. The doors are staying, so the colour answers to them.

The two runs are rarely the same length, and the shorter one often carries the sink, which puts the cut-outs in the piece with the least material to spare. The existing layout is being kept, so the question is whether the old carcasses will take stone in that shape without more support. Where the seam went before is not where it goes now. Reckon on £110 to £550 per square metre for the material supply only, with templating, fabrication and fitting itemised separately.

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. This is the commonest reason a replacement turns out to need more than a straight swap. Strip out first, then measure what is actually there. 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. Whoever manages the block controls the lift booking, the bin store and the visitor parking, and none of that sits in the gift of the household whose kitchen it is. A replacement keeps the units and changes the surface, which is the least disruptive way to do this in an occupied property. Replacement suits occupied stock better than a strip-out.

Chips at an edge or a corner are the usual form, because that is where stone is least supported. A remade piece is cut from the same slab run wherever the slab allows, because a replacement from another batch will not match across a join. Managed buildings allow deliveries through the lift only between set hours, and a day that overruns them finishes with the last piece still on the pavement. We plan the strip-out and the carry as one movement so the kitchen is only out of use for a single day. Both movements are planned as one.

The design and quotation visit is free and carries no obligation, so a figure exists before any commitment. The edge profile is its own line, so a shaped edge and a square one are two different figures. No installed price per square metre is published, because it is not a real number. A stack boxed diagonally across a corner leaves a triangle of dead space, and the top is cut to that triangle rather than to a square return. We would rather find it at template than on the morning, which is why the templater looks behind the units. The old carcasses are rarely level and never were.

No maintenance visit is built into the job. Soap, water, and on the porous stones a seal. Sealing is the one maintenance job that genuinely differs by material, and it is worth knowing which you are buying before the slab is chosen. Granite is porous to varying degrees, so it is sealed when we fit it and topped up over the life of the worktop. Steel windows sit in narrow reveals with a slim cill, which leaves almost no depth for an upstand to return into. The lift car is usually too short and too low to take a full-length piece flat or on edge, so stone either goes up the communal stairs with their half-landings and winders, or the run is designed with joins that suit the staircase rather than the kitchen. What the last fitter did to the wall shows up on strip-out.

A Belfast or butler sink has to be installed and at its final height before the template, because the stone is cut to sit on it. A piece with a bowl and a hob cut into it is the fragile one, and it is handled accordingly. Nothing is cut out in the kitchen. Cutting a bowl on site is how worktops get cracked. A tall bank of housings at one end takes a chunk out of the working run, so the usable length of that side is always less than the length of the wall behind it. Old laminate has often been holding a run square for years, and taking it off shows what the units were really doing. Stone wants gables where laminate needed none.
