Liquid Screed Contractors in Islington

We pump liquid screed into Islington flats, extensions and new blocks straight from the mixer, so a whole floor is laid in one visit and can usually be walked on within 24 to 48 hours. The building decides whether it suits. 19% of the borough's homes were built since 2000, and blocks of that age, like those going up at Holloway Park, are normally designed around a thin liquid screed laid over underfloor heating.

Where pumped screed suits Islington floors

Liquid screed pays off on open, level floors with few obstructions. In Islington that tends to mean three kinds of job. The first is a new build plot or apartment floor on one of the large brownfield sites, such as Holloway Park or the Triangle Site on the Islington side of York Way, which forms part of King's Cross Central. The second is a converted period house where the ground floor has been dug out and a membrane and insulation laid, leaving a clear area to fill. The third is an opened-up kitchen and living room where the owner wants underfloor heating.

Because the screed flows, it settles around pipes without leaving voids and reaches a flatness of SR1 or SR2 without heavy hand work. Over insulation it can be laid floating from about 35mm in a home, or 40mm on commercial floors, well under the 65mm a hand-laid sand and cement alternative needs. That saving in depth matters in a basement, or in a flat where door thresholds and stair nosings cannot move.

Liquid screeds come in calcium sulphate and cement based types, and the right one depends on the room and the finish. Calcium sulphate products bring their own testing and sanding rules, set out on our calcium sulphate flow screed page. For a wet room, or an area that may stay damp, a cement based product is the safer route.

Getting the pump hose into an Islington flat

The pump and mixer lorry park at the kerb, and the hose runs from there to the room. On a terraced street it may go through the front door and along the hall; in a block of flats it can climb the stairwell or pass through an upper window. Hoses reach a long way, but every bend, stair and landing needs planning and protection.

Before a date is booked we ask four things: where the lorry can stand, whether a parking suspension is needed, how many floors the hose must climb, and what the route passes through. Carpets and paintwork in common parts are covered, and the managing agent is told the day in advance.

Once poured, the floor can usually be walked on within 24 to 48 hours. Drying before flooring takes longer, at roughly one day per mm for the first 40mm and slower after that, and ventilation makes a real difference in a closed-up flat. Our guide to screed drying times explains how to plan the flooring fitter around it.

FAQs

Liquid Screed in Islington: your questions

How thick should liquid screed be in an Islington flat?

Over insulation, liquid screed is usually laid floating from about 35mm in homes. Over underfloor heating it needs at least 25mm of cover above the pipes, giving a total of 45 to 50mm. In a converted flat where floor heights are tight, that is often thinner than a sand and cement screed would be, which helps thresholds and doors line up.

Can liquid screed be poured in a flat above someone else's home?

Yes, provided the floor below is built for it. In a converted house the separating floor needs acoustic treatment before any screed goes down, and the build-up has to suit the joists or slab underneath. Liquid screed is heavy when wet, so the structure is checked first. We plan the build-up with you and your builder before pricing the job.

What does liquid screed cost per m² in Islington?

Published 2026 UK figures put liquid screed at £24 to £31 per m², and liquid screed over underfloor heating at £20 to £35 per m². A small flat floor tends to sit at the upper end because the lorry and pump cost much the same whatever the area. Our screeding cost guide breaks the figures down, and every job is priced in writing.
