Rebuilding Metro-land ground floors on Amersham on the Hill
When a Metro-land house on the Hill is renovated, the ground floor is often the part that lets it down. Suspended timber can be rotten or springy, and early concrete without a membrane lets damp rise into new flooring. Homes built between 1919 and 1944 make up 21% of Amersham, so plenty of houses in the town are of that age.
The fix is a new floor build-up. The old floor is broken out or lifted, the ground is prepared, and then a membrane, insulation and a screed go down. Our insulation and membranes service can supply and fit the layers below the screed, so one team handles the whole build-up.
On a Metro-land rebuild, the top layer is normally sand and cement. We mix it on site room by room, which lets a hallway, a front room and a kitchen each go down at their own depth. It is laid by hand, which suits awkward shapes, steps and thresholds in older rooms. Over insulation in a house it floats at 65mm or more. Stuck down to sound concrete as a bonded layer, 25 to 40mm is enough.
The other consideration is drying. At 65mm, it is slow to dry: around a day for each of the first 40 millimetres, then slower, so the renovation programme has to allow for it. Where the builder needs the room back sooner, a quicker drying version of the mix shortens the wait, at £20 to £28 per m² going by 2026 published rates.
Wet rooms, falls and small rooms in Amersham homes
However the rest of an Amersham house is floored, certain rooms must have a cement screed. Walk-in showers and wet rooms slope to a drain, and we can trowel sand and cement to that slope accurately by hand. Because calcium sulphate suffers if it stays wet, the tanking sits on a cement base.
Small rooms are the other place sand and cement is practical. A cloakroom, a utility or a single bedroom converted to a bathroom does not justify a pump and a truckload of liquid screed. Mixing on site keeps the job in proportion, and on small, awkward rooms like these it is usually the cost effective option as well.
Garages also come up in a town with this many detached houses. Turning a garage into living space usually involves lifting its floor to the house level, with insulation beneath a new screed.
For thickness decisions, the screed thickness guide sets out typical depths for bonded, unbonded and floating screeds. Beaconsfield, a few miles south, has its own Beaconsfield sand and cement page.
