Floodgate Adjustable Door Flood Barrier review
Homeowners in a known flood-risk area with an inward-opening door who want a reusable barrier rather than sandbags.
By Tom Rowland · Updated 20 July 2026 · Price checked against our tracker
A serious, UK-made door barrier that expands to seal a doorway in minutes and holds water to around 60cm without any permanent modification. It is a genuine step up from sandbags for a defined flood risk, but it is a considered purchase rather than a grab-bag item, and it only works on inward-opening doors with a sound frame to seal against.
Approximate typical UK street price as of Jul 2026, averaged across manufacturer and retailer listings (floodgate.ltd.uk store, Moray Council eshop, JT Atkinson). Price varies by size band across the 7 widths, roughly £450-£490; an occasional £25 online discount applies.

- Reusable and quick to deploy in minutes with no tools, sandbags or permanent building work
- UK-made steel-and-neoprene construction that expands to fit a range of door widths and forms a watertight seal to roughly 60cm
- Widely used by councils and flood-risk households, so it is a known, well-supported product rather than a novelty
- Expensive compared with sandbags or FloodSax, at roughly £450-£490 depending on size
- Only suits inward-opening doors and needs a flat, sound frame and reveal to seal against; it does nothing for water entering via airbricks or walls
