Floors may be made of tile, stone, concrete or wood. It is often necessary to lift old flooring and level the ground before laying a new floor.

If the ground surface is uneven, the builders will use screed to  provide a flat base for the new floor. A layer of concrete is poured over the area and smoothed, drying to give a perfectly level surface over which other flooring can be laid.

Before laying a new floor, it is worth considering installing underfloor heating. This can be delivered through electric cables laid under the flooring and heated from the mains electricity supply or a traditional 'wet' piped system. Underfloor heating can be installed under any type of flooring.
