Pipe cover and depth in Egham's newer homes
A heated screed does two jobs. It has to move warmth out from the pipes to every part of the room, and hold up the tiles or boards without cracking. Both depend on getting the cover over the pipes right.
A liquid pour has to bury the pipes by 25mm or more, giving a screed of usually 45 to 50mm. As it flows it fills every gap round the pipes, so no air is trapped and the room heats up sooner and more evenly. A hand-laid sand and cement floor needs about 45mm over the pipes, which adds depth and weight. Our screed depth guide shows how these figures sit on top of the insulation.
Before any pour, the build-up is checked: insulation laid tight, an edge strip round every wall, a membrane where the specification calls for one, and the pipes fixed and tested. We can provide insulation boards, edge strip and membrane; the heating pipes themselves never do, as K & B does not fit them.
Egham's newer housing suits this kind of floor from the design stage. On an extension to a post-war or 1970s to 1990s semi, the heated floor is being added to an older house instead, and the new floor has to finish level with the existing rooms. A step at the join between old and new can be dealt with by levelling the floor before flooring.
Commissioning heated floors in Egham homes and garden rooms
Rushing the first heat-up is how a lot of heated floors get damaged. Calcium sulphate can normally have the heating brought on from around day 7. Sand and cement has to wait at least until day 21. In both cases the system starts at a low flow temperature and is raised a little at a time. You get the warm-up plan on paper, so you and your heating engineer are working from one schedule.
Garden rooms add their own checks. The base should be a sound slab, the building weathertight and the insulation continuous under the whole floor, otherwise heat is lost into the ground.
Retrofitting heating into the Victorian and Edwardian houses of Englefield Green and older Egham is a bigger job. Their ground floors often have to come up anyway during renovation, which creates the depth for insulation, pipes and screed. Where the floor cannot be dug out far, a liquid screed at minimum cover keeps the height down.
In published 2026 figures, pouring liquid screed over heating pipes is priced from £20 to £35 per square metre. For the pour itself, see liquid screed in Egham, or the same service in Windsor.
