Sand and Cement Screeding in Southwark

Across Southwark, our sand and cement screed is mixed at the property and packed down by hand, room by room. It earns its place in the borough's older houses: 26% of Southwark's homes were built before 1919, and renovating a house of that age often means digging out a tired solid floor and starting again. Hand-laid screed copes with narrow hallways, small rooms, wet rooms that need falls and any floor that must have a cement base.

Rebuilding old floors in Peckham and East Dulwich terraces

Victorian terrace renovations and side return extensions in Dulwich, East Dulwich, Peckham and Nunhead often uncover original floors with no damp proof membrane. A floor like that may look fine under carpet, then turn out to be damp, cracked or crumbling once the kitchen units come out. Patching it rarely lasts.

In a Peckham or Nunhead terrace, the repair that lasts means lifting that floor completely and building a new one from below, laying insulation, then a membrane against damp, then fresh screed. Domestic floating screeds of this type go down 65mm thick, and commercial ones 75mm. If the concrete underneath turns out to be solid and just needs resurfacing, a 25 to 40mm bonded screed can go directly onto it once prepared. Our guide to screed depths sets out which thickness fits which floor.

Laying by hand works well in these terraces, since every batch can be mixed for the room it is going into. The long, narrow ground floors of a terrace, a small back addition and a step down into the side return can all be laid in one visit, with each area mixed and compacted to its own depth. The insulation and membrane are part of the same job, and you can read more about them on our insulation and membranes service.

The trade-off is drying: roughly a day for each millimetre up to 40mm and slower past that, which is longer than liquid screed takes. Leave room for it in the build schedule before you book a floor fitter.

Wet rooms, garages and conversions in Southwark

Old house or new flat, certain rooms in Southwark have to have a cement based screed. A wet room or level-access shower needs the screed sloped so water drains away, and calcium sulphate products are ruled out on any floor that will get wet. Sand and cement can, and it takes tiles directly once dry.

Flats in converted buildings account for 12% of Southwark's homes. Refitting a bathroom or kitchen in a conversion often means a small, awkward floor on an upper storey, reached only by a shared staircase, where a pump makes little sense. A barrowed, hand-laid screed is the practical choice there: it is cost effective on small jobs and leaves no hose across a neighbour's landing.

Garages being turned into rooms need the floor raised, insulated and levelled to meet the house, and our garage floor screed guide covers how that is done. Short on time? A faster drying cement screed mix brings the flooring date forward, and adding fibres for crack resistance costs £1 to £3 more per m².

FAQs

Sand and Cement Screed in Southwark: your questions

Can new screed go straight over an old Victorian floor?

It can, but only on a base that is solid, dry and firmly stuck down. Many original solid floors in Southwark terraces have no membrane, so laying screed over them traps damp and the new floor fails. In that case the old concrete comes up in full, and we rebuild over new insulation with a membrane laid beneath. A firm, dry slab can take a bonded screed of 25 to 40mm instead.

How long does sand and cement screed take to dry in a Dulwich extension?

A 65mm floor in a Dulwich side return takes well over a month in normal conditions, because drying runs at about a day per millimetre over the first 40mm, slowing after that. Ventilation and heat in the room make a real difference. A hygrometer test tells you when the floor is ready, and quick drying mixes are available if the kitchen fitter cannot wait.

Is sand and cement screed cheaper than liquid screed?

Usually per m². Under the 2026 published UK figures, the hand-laid kind runs from £18 for each square metre to a ceiling of £25, while liquid sits higher, between £24 and £31. On the small, broken-up floors of a Southwark terrace or conversion the gap can widen, because there is no pump to set up. On one big open floor the two prices sit closer together.
