Liquid Screed and Underfloor Heating in Whole-House Renovations

Whole-house renovations are among the more complex jobs we support because the existing building rarely presents a uniform starting point. One room might be down to bare earth after a solid floor is dug out, another might have an intact suspended timber floor being upgraded, and a third might be a later extension already at a different level. Liquid screed UFH can work across all of these, but each area needs its own buildup decision rather than a single blanket specification.

Sequencing is often the biggest practical issue on a renovation. Screed needs a stable, complete substrate and cannot be poured around unfinished walls, incomplete first-fix, or areas still being excavated. On a full renovation this usually means agreeing a room-by-room or phase-by-phase pour plan with the main contractor so screed goes in once each zone is genuinely ready, rather than being rushed to fit an overall programme that assumes a new-build sequence.

Because renovations often also involve upgrading insulation standards, the increase in floor buildup depth compared with the original floor can be significant. This affects skirting heights, door thresholds and sometimes stair bottom risers, so it's worth mapping finished floor levels across the whole ground floor early in the design rather than room by room in isolation.
