1) The impact of recent storms: why garages flooded so easily

Storm Babet alone caused around 2,000 property floods across the UK, with insurers estimating £560 million in storm-related claims across Babet, Ciarán and the winter storms that followed. Many of those affected reported water entering through vulnerable garage doors.

In 2024 and early 2025, additional UK storms - including Storm Henk, Storm Isha and Storm Jocelyn — brought more high winds and flash flooding, again overwhelming homes with gaps under garage doors. These events exposed a common pattern:

• Wind-driven rain pushed water under unsealed garage doors.
• Driveways sloping toward the garage accelerated flooding.
• Older or worn seals failed during prolonged rainfall.
• Blocked drains or standing water outside the garage allowed overflow inside.

The result? Damaged belongings, ruined flooring, soaked tools and costly insurance claims.

2) Key lessons from Babet, Ciarán and recent severe storms

Extreme weather is becoming more common in the UK, but small, practical steps can make a huge difference. Here are the biggest lessons learned:

Lesson 1: Garages without threshold seals flood first

Many households affected by Babet reported water entering from the bottom of the garage door. A threshold seal creates a raised barrier that blocks wind-driven rain and surface water before it enters. GaraDry’s PVC thresholds mould to uneven concrete, providing a tight, watertight seal.

Lesson 2: Side seals stop wind-driven rain

With storms like Ciarán producing intense crosswinds, rain often entered through the sides of garage doors. Adding side seals or brush strips closes these gaps and prevents sideways spray from tracking into the garage.

Lesson 3: Annual seal checks matter

After Storm Henk, many homeowners discovered that their seals had become cracked, brittle or compressed over time -reducing performance when it mattered most. A yearly inspection before winter helps ensure seals remain watertight.

Lesson 4: A sloping driveway increases flood risk

If your driveway directs water toward the garage, storms with heavy downpours can quickly overwhelm the entrance. Pairing a threshold seal with a trench drain or drainage channel provides dual protection.

Lesson 5: Have a simple storm plan

Many affected homeowners said they wished they had taken small preventive steps sooner. Simple additions like sandbags, water leak sensors or a portable pump can prevent severe damage if water levels rise.

3) Expert insight: why storms are hitting harder

Meteorological perspective: “The UK is seeing more frequent short-duration, high-intensity rainfall events. These are particularly problematic for low-lying entry points like garages,” 

Insurance reminder: “The average UK flood claim exceeds £30,000. Most losses come from ground-level water entry - something seal failures often contribute to,” 

GaraDry’s technical team also notes that enquiries spike immediately after major storms — clear evidence that homeowners want stronger, proactive water protection.

4) How to storm-proof your garage before the next major weather event

You can’t control the weather - but you can control how prepared your home is. These steps help protect your garage from severe rainfall and wind-driven water.

Install a high-quality threshold seal

Threshold seals block surface water, draughts and debris. GaraDry PVC seals compress to the ground and form a watertight barrier - far more effective than basic brush seals for storms.

Add side seals for full perimeter protection

Side seals close the gaps down the door edges where crosswinds can force rain inside.

Check for visible gaps or light intrusion

If you can see daylight under or around the door, water can (and will) get in during storms.

Clear drains and remove debris

Storm-blocked drains are a frequent cause of garage flooding. Keeping channels clear improves water flow away from the entrance.

Use water sensors or alarms

These alert you to rising water levels early, allowing you to react quickly.

Have sandbags or flood sacks ready

Even with a strong threshold seal, having backup protection gives peace of mind during extreme storms.

5) Case story: a dry garage during Storm Isha

One customer in the North West had recently installed a GaraDry 30 mm threshold after repeated issues with standing water outside the garage. When Storm Isha brought intense wind and rainfall, they reported that the garage stayed completely dry - while several neighbours experienced flooding.

“It was the first time we didn’t panic during a storm. The difference was instant,” they said.
