Rear extensions on Denton and Mount Pleasant semis
A rear extension on a semi usually ends up as one long room: the old kitchen, the new floor beyond it and often a set of glazed doors to the garden. Laying that by hand means bays, joints and days of work. A pumped liquid screed covers it in a single visit and sets as one flat, dense surface.
Flatness is where it earns its keep. Surface regularity to SR1 or SR2 is readily achievable, so large tiles, LVT and engineered boards go down without a lot of extra preparation. Liquid screed also shrinks far less than sand and cement, so a long kitchen and extension needs far fewer joints.
How thick it goes depends on what is underneath. Floating on insulation in a house, it can be as thin as about 35mm. Put wet heating pipes in and it must sit at least 25mm above them, so most heated floors finish at 45 to 50mm, with the screed wrapping each pipe and leaving no gaps. That makes it the usual partner for underfloor heating screed in Newhaven, giving a faster warm-up and better heating efficiency.
Then there is the step into the old house. Before pouring, we check the finished level of the existing house so the extension lines up at the threshold. Some liquid screeds are calcium sulphate, others are cement based, and the room decides between them; a utility or shower area that could get wet should have the cement based one.
Pumping to Newhaven flats and upper floors
Flats make up 21% of Newhaven's homes, and liquid screed reaches them in the same way it reaches a ground floor extension: through a hose from the pump at street level. The hose runs up the stairwell or, where that is awkward, through a window. The mixer lorry needs somewhere to stand for a few hours, so parking and any permission for the space are sorted before the day.
Trade figures put pump hire at £300 to £600 per day (trade2base, June 2026), which gives a sense of the equipment behind a pumped pour. Our pump comes with our crew, and we do not rent out pumps or other machines. The way the pump, lorry and hose are arranged is described on our screed pumping page.
One honest caveat. Of Newhaven's homes, 19% date from 2000 or later, and at places like West Quay and Safford Park the floors are more likely to want a latex or self levelling layer than a whole new screed. Where a floor is sound and only needs a smoother surface for new flooring, a thin layer of compound costs less than a pour. Our page on levelling Newhaven floors explains when that applies.
