Liquid Screed Contractors in Letchworth

On a Letchworth kitchen extension or an opened-up ground floor, pumped liquid screed gives a flat, dense surface in one visit, and it can be walked on within 24 to 48 hours. The Letchworth detail worth knowing is how little of the housing is recent. Only 10% of homes were built since 2000, so in Letchworth liquid screed is more likely to go into an extension or refit on an existing house than onto a new build plot.

Liquid screed on the Grange and Jackmans estates

Kitchen and extension floors are the typical jobs on the post-war estates, and a wide new room that opens into the existing kitchen is good ground for liquid screed. It flows around corners and finds its own level, so a large L-shaped room is poured in one visit without the joints a hand-laid screed would need.

Depth is the main planning point. Liquid screed floating on insulation in a home can go down at about 35mm, where sand and cement would want roughly 65mm, and the depth saved can go to the insulation. The new floor has to meet the existing kitchen at the same finished height, so levels are set before the pour and checked across the doorway.

Flatness comes easily. Laid well, it reaches SR1 or SR2 when checked with a 2m straightedge, useful if the new kitchen is getting LVT or big format tiles. It is not quick to dry, though: allow roughly a day for each millimetre up to 40mm, and trust a hygrometer over the calendar before the flooring goes on.

There are two broad types of liquid screed, calcium sulphate and cement based, and the right one depends on the room and whether it may get wet. If you are torn between this and a hand-laid floor, our comparison of the two screed types sets them side by side. If a specification names a CA grade, the page on anhydrite flow screed specification covers it in detail.

Pump access and upper floors in Letchworth

Flats make up 21% of Letchworth's homes, and an upper floor flat changes the pour. We leave the pump down on the road and run the hose up the stairwell or in through a window, so we need to hear which floor the flat is on, how the hose would get there and what the managing agent allows. Protecting communal areas is part of the plan.

For houses, the pump and lorry need somewhere to stand for a few hours close to the property. Where parking outside is tight, tell us and we will plan the hose run and the timing around it. Published 2026 figures put pump hire at £300 to £600 per day, which is part of why very small rooms are often better done by hand.

Liquid screed itself runs at £24 to £31 per m² on that same 2026 list, where sand and cement sits at £18 to £25. On a large open extension the faster laying and the shorter wait before walking on it often balance that difference. Outside the town, we also lay liquid screed in Hitchin and Baldock.

FAQs

Liquid Screed in Letchworth: your questions

How long after pouring liquid screed can I walk on it?

Most people can step onto it after 24 to 48 hours, though the exact time turns on the product used, how deep it is and how warm the house is. Walking on it is not the same as loading it or laying flooring. Keep stacked tiles and other heavy loads off it for a while yet, and hold back the floor covering until a moisture test passes, which is a much longer wait.

Is liquid screed worth it for a small Letchworth kitchen?

Often not. On a single small room, the cost of bringing a mixer and pump can outweigh the time saved, and a hand-laid sand and cement screed may be cheaper. Liquid screed pays off on larger, open floors, knock-throughs and heated extensions. We will tell you which makes more sense once you send the floor size and access details.

Can liquid screed be laid over an existing concrete floor?

Yes. It can be laid over a separating membrane on sound concrete, or over insulation laid on the slab. We check the concrete for level, damp and movement first, and set the depth to meet the surrounding floors. If the old slab has cracked or dropped, it may need repair or removal before any new screed goes down.
