Which screed suits which part of Welwyn Garden City
Census 2021 counted 51,504 people in the Welwyn Garden City built-up area, and the way the town was planned still helps when choosing a floor. The older housing lies west of Parkway, the tree-lined mall that runs almost a mile through the middle, and the newer districts lie to the east.
West of Parkway, an older house's solid ground floor may have cracked or dropped, or may never have been given a damp proof membrane. Those floors usually come up completely and go back with insulation and a membrane underneath and hand-laid sand and cement on top, a screed that copes with the small rooms, tight doorways and wet areas these older houses tend to have.
Rear extensions and kitchen knock-throughs are common across the town, on both sides of Parkway. That long open floor is what pumped screed for extensions handles well: it levels itself, and it is ready for foot traffic in 24 to 48 hours.
Heating changes the choice again. Retrofitting wet underfloor heating into an existing house is popular here, and a thin liquid screed keeps the build-up low enough to meet the floors and door thresholds already in place. Our page on screed over underfloor heating sets out the pipe cover each type of screed needs.
Not every tired floor needs replacing. Where the slab underneath is solid and only out of level, a smoothing compound gets you there faster and for less money than screeding again, and it normally goes down before LVT or big tiles anyway.

Pump access, timing and trade units in Welwyn Garden City
Screeding comes partway through a project, so the date hangs on whoever works before and after us. By pour day we need the roof on, windows and outside doors fitted, the wet plaster finished and any heating circuit pressure tested. Then the floor has to dry for a time set by its depth and material, and the tiler and kitchen fitter should be booked to fit around that.
Liquid screed arrives by hose, so the mixer and pump need a spot close enough for that hose to run in to the house. When you ask for a price, mention restricted parking, a shared frontage or a back garden reached only through the house, and we plan the hose route to suit.
Larger schemes bring their own specifications. The Wheat Quarter scheme, near the disused Shredded Wheat factory that remains a landmark beside the railway, has approval mainly for homes, and projects of that kind often name a calcium sulphate grade. Our anhydrite flow screed page explains what those grades mean for drying, sanding and testing.
Industry was placed on the east side of the town beside the railway. The workshop and trade counter units along Bessemer Road and in Mundells and South Mundells, and the offices at Shire Park, need flat floors for racking, vinyl or raised access systems when they are refitted. Floors like those are priced and laid as commercial screeding jobs.
