Garage and porch conversions on Corby's New Town estates
Converting a garage into a room is one of the typical floor jobs on a mid-century estate. On a 1950s or 1960s Corby estate, the old garage slab is normally lower than the hallway and has no insulation beneath it. To bring it up to the hallway, a membrane goes down first, then insulation boards, then the screed. If you are planning one of these conversions, the step by step garage screed guide takes you through each layer in order.
A hand-laid mix fits that job. We batch it on the drive to the depth needed, lay it a bay at a time, tamp it down hard and float it off level. Over insulation in a house, the floating screed is laid 65mm thick. Where the garage slab is solid enough to bond to, 25 to 40mm can do, which saves height under a low garage door opening.
Terraced houses make up 27% of Corby's homes, and a terrace often means one route in, through the front door. A hand-laid screed arrives as sand and cement, and can be barrowed through a hallway without needing a hose run or a pump bay outside.
Porch conversions and small rooms follow the same logic. A pump is hard to justify for a few square metres, and hand-laid screed can be shaped around thresholds and steps. Where an original floor has failed completely, the answer is to break it out and relay it, and preparing the base is covered on the floor preparation service page.
Wet rooms and early loading in Corby homes
There are jobs where a cement screed is not just an option but the requirement. A walk-in shower or wet room in a New Town semi needs its floor sloping down to the drain, and a cement mix can be trowelled to that slope and will put up with water that would damage calcium sulphate. Utility rooms with a washing machine, where a leak is always possible, follow the same reasoning.
Some floors also need to take load early, such as a workshop area or a floor other trades need to use soon. Additives help here: fibres improve resistance to cracking and add £1 to £3 per m² on published 2026 figures, while rapid drying additives shorten the wait before flooring. See fibre reinforced screed for more.
The trade-off against liquid screed is drying speed. Sand and cement dries more slowly, and a heated floor laid in it should not have the heating turned on for at least 21 days. For a like-for-like look at both, the liquid versus traditional screed comparison is worth reading. Homes towards Desborough are covered on the Desborough sand and cement page.
