Sand and Cement Screeding in Wandsworth

Hand-laid sand and cement screed is the usual way to rebuild a failed floor in an older Wandsworth house. Pre-1919 houses in Balham, Tooting and Earlsfield often have ground floors with no membrane at all, so a renovation means taking the old floor out and building it back up with a membrane, insulation and screed. With 22% of the borough's homes terraced, that work often happens in narrow side returns and small back rooms, where a hand-laid screed is simpler to place.

Full build-ups in Earlsfield and Tooting houses

The problem in a house of this age is usually what is missing. Without a membrane, moisture rises into the floor, and any modern finish laid on top can lift, stain or smell. Without insulation, the room loses heat through the ground.

The fix is to break up the old floor and dig deep enough to fit every layer it should have had. That means a damp proof membrane at the bottom, insulation above it and the screed on top. As a floating screed on insulation, a domestic sand and cement floor is laid at 65mm. That depth gives it the strength it needs because it is not bonded to anything below. Breaking out the old floor is part of our floor preparation work, and what goes beneath the screed is set out on our membranes and insulation page.

If the concrete under a Balham or Tooting kitchen is solid and only its top is poor, we can bond a 25 to 40mm screed straight onto it. That saves height, which helps where the new floor must line up with an original hallway or the step into a garden.

Because it is mixed on site and compacted by hand, sand and cement suits the awkward shapes that come with a side return: long, narrow strips, doorways at odd angles and junctions with old walls. We close the surface off hard and flat, ready to take tiles, wood or LVT.

Basements and wet rooms in Wandsworth homes

Basements are a regular part of house work in Wandsworth, and cement is the safer screed below ground. A basement floor may see moisture from the ground or from the waterproofing system around it, and calcium sulphate does not tolerate that. Sand and cement stays sound.

Wet rooms follow the same logic. Water must run off towards the drain, and only a screed laid by hand can be shaped into that slope; a self-levelling one flattens itself out. It is also the right base for the tanking and tiles that follow.

The trade-off is drying. At 65mm, this floor stays damp far longer than a thin liquid pour: roughly a day for each of the first 40 millimetres, and slower after that. A quick drying screed shortens that when the programme is tight.

In 2026 the published range is £18 to £25 per m² for standard sand and cement and £20 to £28 for a quick drying mix. On a small job with no pump to set up, it is often the more economical route.

FAQs

Sand and Cement Screed in Wandsworth: your questions

Can I lay a sand and cement screed myself?

On a tiny patch you could, though it is trickier than it seems. You need a mix that is neither too wet nor too dry, packed down properly and trowelled level wall to wall, normally 65mm deep over insulation. Getting it wrong leads to hollow spots, cracking or an uneven floor, which costs more to put right than laying it properly.

How long before tiling a new sand and cement floor?

For the first 40mm, think in terms of a day per millimetre; deeper than that, every extra millimetre is slower. A 65mm floor therefore needs several weeks, even in good conditions. A cold or unventilated basement takes longer. Test the moisture before tiling rather than counting days, or use a quick drying mix if the date is fixed.

Is sand and cement screed stronger than liquid screed?

Neither is simply stronger. Both are made to a specified strength, and both are laid on top of a slab or insulation rather than acting as the structure. Sand and cement is better in wet areas and where the floor must fall to a drain; liquid screed is flatter over large open floors.
