The housing stock
What we are usually working with in North Cheam
Solid brick with a sand and cement render is firm to work against and reliably out of plumb across the length of a run. Splashbacks come off the same slab run as the tops, which means the decision has to be made before fabrication starts. Panel joints land over a unit line, never mid-span.
Shop-top flats here are reached by a single straight stair from the street with a low soffit at the top, so we measure the headroom as well as the tread width before sizing pieces. The A24 and A2043 carry heavy traffic with no stopping outside the parade, so shop-top flats are worked from a side road; the residential grid behind has driveways and easy parking.
The extension is commonly a flat-roofed addition of the seventies or eighties with a shallower floor build-up, so the two halves of the room do not sit at one level. What catches people out is the junction between the old floor and the extension floor, which is rarely at the same level, so a run carrying across it needs the units packed before stone goes on. What the last fitter did to the wall shows up on strip-out.
What we are usually templating in is 1930s semi, 1930s terrace, flats above parade shops and post-war infill. The differences between them show up at template, not at enquiry.
There is nothing to visit in North Cheam. Samples are posted free, the template is taken in your kitchen and the stone is fitted there too.
