Pipe cover and floor height in Basingstoke extensions
Screed is what turns a mat of plastic pipes into a warm floor. It surrounds the pipes, spreads the heat and gives the flooring a firm base. Too little cover and the floor cracks over the pipe runs; too much and it takes an age to warm up.
Pumped over the pipes, liquid screed must bury them by 25mm or more, so the layer usually finishes 45 to 50mm deep. A hand-laid cement screed needs about 45mm above them, giving a thicker and heavier slab. A liquid pour also flows fully round the pipes with no air pockets, which helps the floor respond faster. For the pumped option, see liquid screed for Basingstoke extensions.
In an extension, height is usually the limiting factor. The insulation, the pipes and the screed together have to finish flush with the existing kitchen or hallway. On a retrofit, where heating is going into an older room and the ceiling or door heads cannot move, every millimetre counts, and the thinner liquid build-up can make the difference.
Before we pour, we check that the insulation is laid tight, the edge strip runs round every wall and the membrane is sealed. If the build-up underneath is not in place yet, our insulation and membranes service can supply it. Of Basingstoke's homes, 18% were built between 2000 and 2014, and their owners are adding heated extensions as well.
Switching the heating on in a Basingstoke home
The heating is part of the drying plan, but it cannot be rushed. With calcium sulphate, gentle warmth is usually allowed from around day 7. A cement screed gets no heat at all until at least 21 days have passed.
The first warm-up should be gradual. The system starts low and is raised a little each day until it reaches working temperature, then held there before it is brought back down. Your heating engineer sets the schedule for the system, and we hand over written guidance on the screed side so both match. Heating a young screed hard on the first day is one of the usual causes of cracking.
Detached houses make up 21% of the town's homes, and their larger extensions and garden rooms often run heating across the whole floor. On those bigger areas a liquid screed keeps joints to a minimum. Where the room includes a shower or utility area, a cement based screed is used there, and our sand and cement screed service in Basingstoke covers that side.
As a budget figure, a liquid screed laid over heating pipes costs between £20 and £35 a square metre on 2026's published UK prices. If you are comparing quotes across north Hampshire, see underfloor heating screed in Fleet.
