Worktop replacement in Hanwell

Yes. Hanwell is on the patch, and the postcodes we work here are W7. It is run from the High Wycombe side, covering Buckinghamshire & Berkshire. A controlled parking zone means either a visitor permit sorted in advance or a suspended bay, and a suspension is applied for days ahead rather than on the morning. 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.

The addition wall is half a brick thick in places and has usually had a damp course injected and been re-plastered, which leaves it neither flat nor consistent. 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. What is under the old top is the real question. A lot of these terraces still have the original outside WC standing in the rear return, so the top has to stop and restart around it rather than run through.

The Uxbridge Road and the approaches to the viaduct congest badly, terraces have no driveways, and the streets near the station are permit-controlled. Door width, hall width and the diagonal at the turn are three separate measurements, and it is the diagonal that catches people out. 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. The strip-out is planned around it. Tell us what the approach looks like when you book the template and it gets built into the day rather than discovered on it.

Yes. On the research for this patch it is the first of the three jobs listed, ahead of worktop installation and worktop templating. 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. Old tops out in the morning, new stone down and sealed the same afternoon. A plumber either side of us. The junction between the original room and the extension is the point to watch, because the two floors rarely sit at the same height. The carcasses have to be sound, because stone is several times the weight of what is coming off. A day, not a project.

A galley run down a side-return extension usually measures longer than a slab will give in one length, so a join is designed in from the start rather than discovered. 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 laser plots the intermediate points. 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. 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. If the carcasses are tired the honest answer is that stone will find that out, and it is better said before than after. Plumber either side of us.
