5 common causes of flooding inside the home
While surface water is the biggest flood risk in the UK, problems like broken pipes, blocked gutters and clogged drains can do just as much damage.
In recent days, more than 100 flood warnings were issued across the country as heavy rain and wind hit parts of the UK on the first day of 2025.
Residents in Manchester were trapped in their homes without running water, while others were rescued from cars stranded in floodwaters.
"Flooding is unpredictable, but there are actions you can take to determine your level of risk and effectively prepare for these hazardous conditions," says Emily Green, an expert at Howarth Timber.
With many counties set to experience snowfall, ice and heavy rain over the coming days, the experts have shared the common causes of flooding in the home — and what you can do to protect your property. Take a look at them below:
1. Broken pipes
Water damage from broken pipes can seep into walls, ceilings and floors, causing substantial damage.
"Heavy objects falling on them or harsh handling during building or remodelling operations can cause broken pipes. Check for water running down the wall near the pipe or beneath a sink or tub if you fear a pipe has broken. Water may also be seen leaking from beneath the floor," says Emily.
"It is important to inspect your pipes on a regular basis and be aware of their location outside of the property."
2. Clogged drains
A clogged drain in the bathroom or kitchen can also cause flooding in the home. When drains are blocked, wastewater can't flow away and can back up into toilets and sinks.
"If your drain is clogged, you may see water backing up into sinks and tubs after they have been used, especially if they are near toilets or showers," says Emily.
"Standing water may also be found in toilets, baths, and sinks after they have been used. Using drain guards in kitchen sinks and a metal mesh drain screen where appropriate can assist in avoiding clogging."
3. Broken appliances
Any appliance with water pipes or lines, such as the dishwasher or washing machine, has the potential to spring a leak.
Emily adds: "If your washing machine, refrigerator, or dishwasher isn't operating properly, water might overflow and flood your kitchen. Improper installation or defective wiring might lead to damaged equipment.
"It's critical to inspect these appliances on a regular basis to ensure they're in good operating order and aren't leaking. Flooding can occur if a pipe is left neglected or is broken."
4. Clogged gutters
Clogged gutters can cause water to pool around the foundation of your home and under the roof.
"When gutters get clogged with leaves or other debris, rainfall collects in them rather than flowing away from the home via downspouts and drains at the base of each wall. Gutter cleaning should be done on a regular basis to guarantee that water is constantly directed away from your property."
5. Foundation damage
Damage to the foundation of your home is another common cause of flooding. This occurs when excess water surrounds your property, or if foundation walls have cracks that enable water to pour through.
"If this happens to your house, foundation repair is vital to avoiding severe flooding. It is advised that everyone living in a high-risk location investigates foundation damage prior to severe weather since this helps to prepare for unexpected events," says Emily.
