Anti-Flood Airbricks
Anti-Flood Air Bricks £120 EA including Supply and Install.
Anti-flood air bricks are a specialist ventilation solution designed to protect suspended timber floors and sub-floor voids from floodwater ingress while still allowing essential airflow. Traditional air bricks provide permanent ventilation to the subfloor area, which is critical in preventing condensation, dampness, and timber decay. However, during flooding events these openings can allow water to enter directly beneath the property. Anti-flood air bricks incorporate a one-way internal valve system that automatically closes when external water levels rise, preventing floodwater from entering the sub-floor void while maintaining ventilation during normal conditions.
These systems are particularly beneficial for properties located within flood-risk zones, flood plains, or areas susceptible to surface water flooding, such as those near rivers, low-lying land, or locations with overwhelmed drainage infrastructure during heavy rainfall. By preventing water from entering the subfloor void, anti-flood air bricks help protect timber floor structures, joists, insulation, and internal finishes from moisture damage, rot, and mould growth that can occur following flooding.
Anti-flood air bricks are commonly installed as part of a wider property flood resilience strategy, alongside measures such as flood barriers, non-return drainage valves, and improved surface water management. When professionally installed, they provide a practical upgrade to traditional air bricks, maintaining essential ventilation to the sub-floor void while offering an important safeguard against floodwater ingress during extreme weather events.
FLood Barrier Doors
A removable flood barrier fitted across external doorways provides an effective first line of defence against low-level flooding and surface water ingress. These systems are typically constructed from durable aluminium panels secured between permanent side posts, forming a watertight seal across the threshold. When heavy rainfall, flash flooding, or rising surface water threatens a property, the barrier can be quickly deployed to prevent water from entering through vulnerable openings such as front doors, patio doors, or low-level entrances. Once the flood risk has passed, the barrier can be easily removed, restoring normal access without permanently altering the appearance of the doorway.
Flood barriers are particularly beneficial for properties located within flood-risk areas or flood plains, as well as buildings exposed to surface water runoff, overwhelmed drainage systems, or nearby watercourses that may exceed capacity during heavy rainfall events. They are commonly installed on homes where door thresholds sit close to external ground level, making them susceptible to water ingress during storms. In many cases, flood barriers form part of a wider property flood resilience strategy, working alongside measures such as non-return drainage valves, raised air bricks, and improved external drainage to help reduce the risk of internal water damage.
These systems are suitable for domestic properties, basements, garages, commercial premises, and any building where entrances are at risk of water ingress during extreme weather events. When professionally installed and correctly sealed, flood barriers provide a practical and reusable protection measure that can significantly reduce the likelihood of internal flooding and the associated structural damage, disruption, and costly repairs.
