Screed for Underfloor Heating in Uckfield

Wet underfloor heating in Uckfield, whether in a new home, an extension or an older house being refitted, needs a screed over it, and K & B lays it. At Ridgewood Farm, new homes are built with underfloor heating and flowing screeds. Across the older estates, heated kitchen extensions follow the same rules. Before pouring we look over the edge strip, membrane and insulation; afterwards the pipes are fully covered and you get the heat-up steps on paper. The pipes themselves are fitted by your heating engineer.

Heated floors in Uckfield's new homes and extensions

Homes built from 2015 onwards make up 8% of Uckfield's stock, and Ridgewood Farm has outline permission for 1,000 more. Floors in new homes like these are designed with heating in mind from the start, so the insulation depth, pipe layout and screed thickness all fit a set finished level. Changing one layer late in the build means rechecking all the others.

The screed's job is to hold the pipes and spread their heat. A flowing mix wraps each pipe without leaving air gaps, and with 25mm or more on top the layer normally ends up 45 to 50mm deep. A thin, dense layer like that responds quickly when the heating comes on. Sand and cement can be used instead with about 45mm of cover, compacted carefully by hand around the pipes, and is the choice for a heated area that may get wet.

On the 1970s to 1990s estates, a heated kitchen extension raises the usual question of levels. The new floor has to finish flush with the existing house, and the lower cover of a flowing screed often makes that easier. See liquid screed for Uckfield homes for how it is pumped and dried.

Fitting the pipework is not part of what K & B does. That job, along with the pressure test, falls to your heating engineer or plumber, and we look over the pipes, insulation and edge strip before pouring.

Commissioning heating and retrofits near Uckfield High Street

How the heating is first switched on matters as much as the screed. Calcium sulphate can normally be warmed from around day 7. With sand and cement, hold off for 21 days or more. After that the temperature goes up in small steps, is held, then comes back down before flooring. Putting a fresh floor on full heat straight away can crack it. You get those steps from us on paper.

Retrofitting underfloor heating in an older house is a different problem. Houses nearer the High Street may already need their original solid floors lifted and relaid, which is the moment to add insulation and heating. The difficulty is height: doors, stairs and skirting are fixed, so the build-up has to fit beneath them, and the reduced pipe cover of a liquid screed can make the difference.

The layers under the screed are just as important. Insulation keeps the heat going up, the membrane keeps moisture out and the edge strip lets the floor expand. The insulation and membranes service covers this where needed. Over in Haywards Heath, the heated screed page for Haywards Heath covers the same work.

FAQs

Underfloor Heating Screed in Uckfield: your questions

What screed depth is needed over underfloor heating pipes?

A flowing screed wants 25mm or more on top of the pipes, which makes it about 45 to 50mm deep. Hand-laid sand and cement needs roughly 45mm above them. Getting the cover right gives the floor its strength and spreads the heat evenly across the room. Our screed thickness guide explains the full build-up, including the insulation underneath.

How soon can flooring go down over a heated screed?

Not until the screed is dry and has passed a moisture test. The heating speeds things up: it can normally start drying calcium sulphate from around day 7, and sand and cement after 21 days or more. Tiles, LVT and engineered wood each have their own moisture limits, so your flooring fitter should test before laying.

Can underfloor heating be added to an Uckfield house without raising the floor?

Sometimes. When the old floor is coming out regardless, as in many older houses near the High Street, the new layers can be planned to finish at the height it was. Where the existing floor stays in place, height is usually the limit, since pipes and screed have to go on top of it. We look at floor height, thresholds and stairs on a survey before advising.
