Heated extensions in Cox Green, Furze Platt and Pinkneys Green
In the suburbs, underfloor heating often comes with extension and kitchen remodel work, and the screed decides how well it performs. Every pipe has to be wrapped completely, with no trapped air, and buried deep enough for the floor to be strong and the warmth to spread evenly.
The figures are specific. With a pumped screed the pipes want a minimum of 25mm on top, and the finished build normally measures 45 to 50mm. Trowelled sand and cement needs closer to 45mm over the same pipes, so that floor ends up thicker. When a Cox Green or Furze Platt extension has to finish flush with the existing house, those extra millimetres can settle which screed to use.
Liquid screed suits heating well. It flows beneath and around every pipe with no voids and gives a faster warm-up. Sand and cement is still used where the room may get wet or the heating installer's specification calls for it. Whichever is chosen, the heating should be designed with the finished floor in mind: the covering, whether tiles, LVT or engineered wood, affects how the system is set up, so share it with both trades early.
Fitting the pipework is not part of our job: your heating engineer puts it in along with the manifold and controls, then pressure tests the system before the screed date. When we arrive we go over the insulation, membrane and perimeter strip, and if you still need those layers we can bring them as part of our insulation and membranes service.

Retrofits and first warm-up in older Maidenhead homes
Adding heating to an older Maidenhead house is trickier, since the doors, thresholds and stairs have already fixed how high the floor can be. In the Victorian houses around Boyn Hill, the old ground floor often needs replacing anyway, and that is the moment to add insulation and heating. The thinner build-up of a liquid screed often makes the difference between fitting heating and not.
Newer homes are simpler. 11% of Maidenhead's homes were built in 2015 or later, and a new home may have its floor planned around heating from the start.
Patience after the pour protects the floor. Give a calcium sulphate pour about 7 days before the heating runs at all, and a sand and cement one 21 days or more. From there, bring the temperature up in stages spread over several days. We give your heating engineer clear guidance on the heat-up. Budget-wise, pumped screed over a heated floor is priced from £20 up to £35 per square metre in 2026 UK published figures. Homes in Windsor have their own heated screed page.
