Heated extensions in post-war Shoreham-by-Sea homes
In a Shoreham-by-Sea house, the obvious place for a heated floor is a rear extension or kitchen diner. It is built from scratch, so there is room for a proper build-up: insulation, the heating pipes clipped or fixed above it, then the screed. The challenge is matching the new finished height to the original floor next door.
Start with the depth over the pipes. Liquid screed has to sit 25mm or more above them, often 45 to 50mm in total. Sand and cement wants around 45mm on top, so the whole floor comes out thicker. Where height is short, pumped liquid screed for heated floors can save valuable millimetres and flows around the pipes with no air pockets.
Retrofitting heating into an original room is harder. The existing floor may be suspended timber or an early slab with no insulation, and floor height is usually tight against doors and stairs. In those rooms the old floor often has to come out so insulation can go in under the pipes. Otherwise much of the heat is lost downwards. We can lay that layer too, through our insulation and damp membrane service.
Laying the pipes is not something we do. The heating engineer lays them, pressure tests the system, and then we pour. Edge strip around the walls lets the screed expand as it warms, and we check it is in place before starting. Flatness for tiles, LVT and engineered wood is part of the finish.
Commissioning heated floors at Kingston Wharf and Free Wharf
On apartment schemes like those at Kingston Wharf and Free Wharf, heated floors are common, and the programme usually depends on when each floor can be warmed. The material sets the earliest date. Calcium sulphate floors can usually be warmed from around 7 days. Sand and cement floors have to wait 21 days or more.
Commissioning is then done gradually. Over several days the flow temperature creeps up in small steps, stays there for a while, then comes back down. That controlled warm-up also helps dry the screed before flooring, but it must not be rushed, or the floor can crack and finishes can fail later.
Whoever turns the heating on, be it the engineer, the site manager or you, gets the heat-up schedule from us in writing with dates against each step. A moisture test still comes before any floor covering, and our guide to how long screed takes to dry explains why the calendar alone is not enough.
Older apartment blocks are different again, because an acoustic layer and limited height can restrict the build-up. A few miles east along the coast, we also cover heated floor screeds in Brighton and Hove.
