As winter approaches, we know that some vehicle owners reach for the keyboard and search for ‘dry storage for cars’. Many will find us listed in the results! We’re based on the Hampshire and West Sussex border. But in fact, we offer more than dry storage, we offer a humidity-controlled environment at our purpose-built facility. But what’s the difference? Read on to discover more…
Dry storage for cars vs humidity-controlled storage.
If you search for dry storage for cars in Hampshire or West Sussex, you’re likely to come across various websites. But, please choose carefully. An outbuilding or barn may mean that your car is in dry storage. But the real question you need to ask yourself is whether this will be an optimum storage environment for your precious vehicle?

At South Downs Secure, based on the Hampshire and West Sussex border, we’re undeniably proud of our humidity-controlled car storage environment. We have installed a system that circulates air around our facility, creating a continually shifting air stream. Our dehumidifier (operating via a humidistat) switches on and off according to the measured level of RH (Relative Humidity) in the space. Our systems maintain an optimum 50% RH within our facility. We are confident that this allows us to safeguard our client’s cars in perfect conditions.
If you choose to store your vehicle in covered (and therefore dry) facilities where the relative humidity is unmeasured, your car may leave in a worse condition than it arrived. If the RH of a building rises above 50%, there is an increased risk of corrosion. Furthermore, with an RH above 70-80% mould can begin to form on leather and other organic materials.
A purpose-built facility:
The only way to ensure optimum conditions for your vehicle is to invest in storage at a purpose-built facility. And if you’re wondering what constitutes purpose-built, here’s a list of systems we have in place.
- Humidity controlled environment, maintaining an optimum 50% RH (relative humidity).
- 24hr monitored CCTV system.
- State of the art, fully monitored security alarm, with auto police and security team response.
- Monitored Fire system, with auto-dial out.
