Frequently Asked Questions (FAQs)
What Size Storage Unit Do I Need for a 3-bedroom House?
For a standard three-bedroom house, you will typically need between 100 sq ft and 150 sq ft of space. However, if you have a large amount of garden furniture or a heavily furnished attic, you may require a 200 sq ft unit. We recommend using our online size estimator or speaking to our team in Crawley for a personalised recommendation.
What Are Common Storage Unit Mistakes?
The most common mistake is underestimating the height of the unit; you can save money by choosing a smaller footprint and stacking items vertically. Another mistake is choosing a facility without climate control, which can lead to moisture damage over time. Storage King Crawley offers climate-controlled units to prevent this.
What Should I Not Put in a Storage Unit?
For safety and legal reasons, you should not store perishable food, pressurised canisters, combustible materials (like petrol) or any illegal items. If you are unsure about a specific item, our manned reception is happy to provide guidance.
