1. Stay Safe First – Floodwater Is More Dangerous Than It Looks

When dealing with a House Floods From Rain, safety comes before saving belongings.

Turn off electricity if safe to do so

If water has reached sockets, appliances, or fuse boxes, do not touch anything. Stay away and call an electrician.

Avoid walking through floodwater

Rainwater often mixes with:

• sewage backing up from drains 
• chemicals 
• bacteria 
• sharp objects 
• electrical currents in hidden places 

A small puddle can hide deep structural issues beneath flooring.

Evacuate if the water is rising quickly

The UK’s Met Office advises immediate evacuation if water levels rise unexpectedly (for more info check: metoffice.gov.uk).

2. Stop the Water Source and Reduce Further Damage

Most rain-related flooding happens because water enters through:

• overwhelmed gutters 
• blocked drains 
• broken roof tiles 
• foundation cracks 
• leaking windows or doors 
• poor slope drainage around the property 

If possible:

Block incoming water temporarily

Use:

• towels 
• sandbags 
• plastic sheeting 
• wooden boards 

Even small barriers help reduce internal damage until help arrives.

Document everything for insurance

Take photos and videos before moving or disposing of anything. Insurance companies rely on this evidence.

5. Prevent Mould Growth – The Most Expensive Hidden Risk

Mould can start within 24–48 hours of flooding. It grows inside walls, under carpets, behind skirting boards, and in corners with poor ventilation.

Our mould prevention process includes:

• complete moisture mapping 
• antimicrobial surface treatment 
• HEPA air filtration 
• controlled heat drying 
• removing damaged plasterboard if needed 

Ignoring mould leads to long-term health problems, especially for children, elderly residents, and people with allergies.

• replacing plasterboard 
• repainting
