Rear & side extensions

Liquid Screed for House Extensions

Small-footprint pours done properly. We turn up, pour 20–60m² in an hour, and leave you a laser-flat floor to tile onto.

Extensions are where liquid screed pays for itself. The area is small, but the finished-floor level has to marry into the existing house perfectly — and traditional sand-and-cement rarely does that without a lot of grinding.

A poured screed lands flat, ties into the existing threshold at exactly the right level, and doesn't hold up the rest of the trades.

Extension screed choice

Liquid screed

  • 20–60m² in an hour
  • Marries to existing FFL exactly
  • SR1 for large-format tile
  • UFH runs at spec depth

Sand and cement

  • Half a day of hand-laying
  • SR2 at best — needs latex before tiling
  • 65–75mm cover over UFH
  • Prone to shrinkage cracks

Common extension screed jobs we do

  • Kitchen-diner rear extensions with wet UFH
  • Side-return kitchens tying into the existing hall
  • Garden rooms and orangeries
  • Basement dig-outs with a poured raft above tanking

Half the extension screed jobs we're called into as a rescue are because someone poured sand-and-cement over UFH at 50mm and the room won't heat up. Get the depth and cover right at spec stage.
