Heavy rain and storms can overwhelm drainage systems, leading to surface water flooding in homes and businesses. This type of flooding often affects multiple properties at once and can carry contaminants from outside environments.
This guide explains how flood damage caused by heavy rain and storms is cleaned, dried, and managed in the UK.
How Heavy Rain Causes Flood Damage
Storm-related flooding may occur when:
- drainage systems are overwhelmed
- surface water enters through doors or air bricks
- water accumulates around foundations
- ground becomes saturated
Flooding may develop rapidly during severe weather.
What Makes Storm Flooding Different?
Compared to internal leaks, storm flooding often:
- brings contaminated surface water
- affects multiple rooms or properties
- increases risk of damp and mould
Cleaning usually requires additional assessment and care.
Initial Response After Storm Flooding
Following storm-related flooding:
- avoid contact with floodwater
- isolate electrics if safe
- ventilate where possible
Professional cleaning is recommended once conditions are safe.
How Flood Damage from Storms Is Cleaned
Water Removal
Standing water is extracted to prevent further penetration into building materials.
Cleaning and Disinfection
Surface water may contain:
- dirt and debris
- pollutants
- biological contaminants
Cleaning and sanitisation reduce health risks.
Drying and Dehumidification
Extended drying is often required due to:
- saturation of floors and walls
- moisture retained in foundations
Drying equipment is used to control moisture levels.
Risk of Mould After Storm Flooding
Storm flooding increases mould risk because:
- moisture levels remain high
- external water can linger in structures
Early drying helps prevent long-term issues.
Insurance Considerations
Insurance cover for storm flooding:
- depends on policy terms
- may vary for external flooding
- may require proof of cause
Insurers often request documentation before approving cleaning.
Can Properties Be Reoccupied?
Reoccupation depends on:
- drying progress
- contamination level
- safety assessments
Premature reoccupation can cause health or structural issues.
Reducing Future Storm Flood Risk
Preventative measures include:
- improving drainage
- installing flood barriers
- maintaining gutters and downpipes
These steps help reduce repeat incidents.
