Worktop replacement in Mildmay

Yes. Mildmay is on the patch, and the postcodes we work here are N1, N16. It is worked on our north London run, along with the rest of Islington. Enforcement zones rarely accept a trade van unloading stone as an exemption, so this gets sorted before the date is confirmed rather than argued about afterwards. 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. Old tops out and new stone in, both through the same gap. We template in your kitchen and fit in your kitchen, so there is nothing to visit and nothing to collect.

Where the side return has been filled in, the old external wall is now an internal one and still carries its render, its gutter line and its old fixings. In most Victorian terraces the kitchen sits in the back addition, so you get a narrow galley with one outside wall and nothing square to work off. Sound carcasses are the one condition. Narrow rear additions here often will not take a 600mm run plus a walkway, so check clearances at template and be ready to advise a 560mm depth instead.

A filtered-street scheme closes several through routes so the approach has to be planned street by street, and parking is permit-only Monday to Friday and tight all day. The terraces are shallow-set with two or three front steps and a hall under a metre wide. Everything comes through the front door and down the hall, so the tightest point on the route is usually the newel post at the foot of the stairs. 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. It sets what the day actually looks like.

Yes. On the research for this patch it is the first of the three jobs listed, ahead of worktop templating and worktop installation. A kitchen carved out of a larger room sits under whatever the original plan left behind, so the run frequently ends at a blocked doorway or a boxed-in service. The carcasses have to be sound, because stone is several times the weight of what is coming off. A day, not a project. Conversions put kitchens where the services could be made to reach rather than where they belong, so runs are short and interrupted. Old tops out in the morning, new stone down and sealed the same afternoon. A day, not a project.

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. Going from a 38mm laminate to 20mm or 30mm stone drops the surface, which shows against tiles, a window board and any freestanding appliance. 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.

A run can measure dead right at both ends and still belly out in the middle, which only appears once the template plots the intermediate points. The old top has been hiding it, so the first honest look at it happens when the laminate comes off. The laminate has been covering it up. 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. A street with houses in single occupation next to the same houses cut into flats produces two completely different jobs from the same elevation. If the carcasses are tired the honest answer is that stone will find that out, and it is better said before than after. Sound carcasses are the condition.
