Screed choices for Potters Bar's 1920s to 1960s semis
Census 2021 recorded 23,394 people in the Potters Bar built-up area, and semi-detached houses make up 47% of its homes. That one house type decides much of the floor work in town.
Height is often the main challenge on a semi. A new extension floor has to meet the original house exactly, with room below for insulation and the right depth of screed. On a wide, open extension, liquid screed for Potters Bar extensions is poured in a day and settles level, which makes matching the old floor easier. Hand-laid sand and cement screed is the better fit when an original floor has to be dug out and replaced room by room, or where a wet room needs falls.
Plenty of these extensions are heated. The pipes change the depth, the choice of screed and when the heating can first go on, so see our page on underfloor heating screed before settling the build-up.
Some floors only need correcting. Where the old and new floors are sound but out of line, or a worn surface is too rough for LVT, self levelling compound for existing floors is quicker and cheaper than a new screed.
Larger schemes are coming too. The Hertsmere Local Plan names garden suburb sites west of Dugdale Hill and on the former golf course off The Avenue, and a housing scheme is planned on the former Canada Life site on the High Street. Specified calcium sulphate floors on schemes like those are covered on our anhydrite flow screed page.

Pours, parking and Cranborne Industrial Estate units
Timing comes first. On a Potters Bar extension that means the roof on, the windows and doors fitted, the plasterer's wet work done and the heating engineer's pressure test passed, all before we pour. Drying follows, and the flooring date depends on it, so fix the screed date first and book the flooring after.
Access comes next. For a pumped floor, the lorry and pump have to stand somewhere the hose can stretch from to the back of the house. A semi with off-road parking at the front rarely causes a problem. If the only space is on the street, or the route to the back runs down a narrow side passage, tell us when you ask for a price. Postcodes here include EN6, and the whole town is covered.
Business premises need a different approach. The Cranborne Industrial Estate, bounded by the railway line, is the largest industrial area in town, with light industrial units and large multi-let buildings such as Cranborne House and Summit House. Older floors like these often need concrete repair, grinding and resurfacing during a refit, and our concrete floor repair service covers that work.
