Picking the right screed for a Southwick house
Census 2021 counted 12,242 people in the Southwick built-up area, which runs in three rough bands. The harbour and its businesses sit south of Brighton Road. The newest housing climbs from Old Shoreham Road towards the South Downs. Southwick Square is the shopping centre. Postcodes here include BN42.
Semi-detached houses make up 42% of homes, and the town has many inter-war and 1950s semis. Their floors lead to a few typical jobs.
A rear extension usually needs screeding to match the existing finished height, so the new kitchen or family room steps straight through from the old house. When that room is big and open, liquid screed pumped through from the street goes down flat in one visit. Planning heating pipes under it? Then the screed depth above them and the first warm-up both need thought, and heated floor screeds in Southwick is worth reading before the plumber starts.
An old quarry tile or timber floor being taken out to add insulation is a different job. Here a hand-laid sand and cement floor copes better with small rooms, hallways and doorways. The same goes for bathrooms and utility rooms that may get wet.
Then there are concrete ground floors that are sound but uneven. Rather than replace one of those, a pour of self levelling compound under the new flooring will often flatten it. And if your architect's drawings ask for a calcium sulphate grade, the material has a page of its own under anhydrite screed.

Brighton Road terraces, timing and access
Floors in the older terraces between Brighton Road and Old Shoreham Road need particular care, because they can have little or no damp proofing beneath them. There, a membrane goes in before any new screed, and the old floor normally comes out first so insulation can be added too. Breaking out the old floor and getting the ground ready is part of our floor preparation work.
On any renovation, the screed has to fit into the building programme. We come in once the room keeps the rain out, the windows and doors are hung and the plasterer's wet work is done. Any heating pipes need fixing and pressure testing by your engineer before that visit. Drying then takes time, and the wait depends on the depth and type of screed, so plan the kitchen and flooring fitters around it.
Access needs a word too. The A259 runs through Southwick and the A27 skirts it to the north, but parking at the house is what decides a pumped pour. Tell us about street parking, side passages and how far the hose must run to the room when you ask for a price.
