Getting pipe cover right in Herne Bay extensions
How well a heated floor performs depends a great deal on the screed wrapped round its pipes. The screed has to surround every pipe without voids, carry enough depth above them to spread heat and resist cracking, and sit on insulation with an edge strip so it can move.
With a flowing screed, the pipes need at least 25mm of cover, which puts the total at about 45 to 50mm. Sand and cement needs roughly 45mm over the pipes, making the whole build-up thicker. That difference matters when a heated extension has to meet the floor of the existing house without a step. On a large open room, liquid screed pumped over the pipes usually wins, because it fills round them completely and is flat enough for tiles, LVT and engineered wood.
Adding heating to an existing older house is trickier. In a pre-1919 house near the seafront, the floor height is fixed by doors, skirtings and the rooms next door, so every millimetre of insulation and screed has to be planned. Sometimes the only way to fit heating in is to dig out the old solid floor and rebuild it from below. Minimum depths for every screed type are listed in our guide to screed thickness.
On the day, we confirm the edge strip, membrane and insulation are down and that the pipework has passed its pressure test before any screed goes in. Any of those layers not yet in place, we can provide and lay ourselves.
Switching the heating on in new Herne Bay homes
The first warm-up is where heated screeds most often go wrong. Heat the floor too soon, or crank it up too quickly, and cracking or curling can follow.
With calcium sulphate, the heating can normally come on from about day 7. Sand and cement must sit for 21 days at the very least. Whichever you have, warm the system gradually, stage by stage; we hand over a clear heat-up schedule so you and your heating engineer are working from the same plan.
The newest homes in town already rely on this. Only 5% of Herne Bay's homes were built from 2015 onwards, but the estates planned at Hillborough, Strode Farm, Greenhill and the old golf course will add many more heated ground floors. Garden rooms and home offices built at the bottom of gardens raise the same questions on a smaller scale.
For liquid screed laid over heating pipes, published rates run from £20 to £35 per m². Where a heated floor also needs work to the slab first, our floor preparation service is priced in the same quote.
