Storage units are generally safe when you choose a reputable storage brand like Sentry Self Storage. Across all Sentry Self Storage sites, CCTV records 24/7 and alarms are monitored 24/7 to help protect customer belongings.
People often worry about theft, damp, pests, or accidental damage when putting items into storage. In practice, the level of safety depends on the facility itself, the condition of the building, the security measures in place, and how items are packed before storage.
At Sentry Self Storage, we help customers store household items, furniture, business stock, and personal belongings across 23 locations. Choosing the right facility and preparing items properly can make a big difference to how safe and secure your storage experience feels.
Security features and access arrangements can vary between storage providers. If you want more detailed information about a particular Sentry site, you can contact Sentry Self Storage directly and speak with the site manager.
Are Storage Units Safe?
Yes, storage units are generally safe when you choose a professional facility with proper security measures, but safety depends on the provider, location, and how you store your items.
Modern self storage facilities are designed to protect belongings from theft, weather damage, and unauthorised access. Professional storage providers usually invest in security systems and site management to help protect customer belongings and maintain safe facilities.
That said, not all storage facilities offer the same level of protection. Older sites or unmanned compounds may have weaker access control, poor lighting, or less monitoring. This can increase the risk of theft or damage.
Many modern storage facilities combine several layers of security. This may include CCTV recording, gated access systems, individual unit locks, alarmed buildings or corridors, on-site staff, secure fencing, and well-lit access areas.
Your own preparation also matters. Even the best storage facility cannot fully protect poorly packed belongings or valuables left unsecured. Using strong locks, sealed containers, and clear organisation helps reduce risk further.
For most people, self storage is a safe and practical option for both short-term and long-term use.
What Security Do Storage Units Have?
Most modern storage facilities use several security measures to help protect your belongings, including surveillance, controlled access, and site management.
Good storage security works by making unauthorised access difficult at every stage. Rather than relying on a single lock or camera, professional facilities combine physical barriers, digital monitoring, and staff oversight.
CCTV Recording
Sentry Self Storage has CCTV camera recording 24/7 across all sites. Cameras are used to monitor activity around key areas of the facility and help support site security.
CCTV is an important part of storage security because it can deter unauthorised activity, record movements on-site, and provide useful footage if an incident needs to be reviewed.
Controlled Access Systems
Most reputable storage providers use controlled access systems such as PIN code entry, keycards, electronic gates, or smartphone access systems. These controls help limit who can enter the facility and can create a record of site access activity.
Access arrangements can differ between storage providers, so it is always worth checking how entry works before you book.
Individual Unit Locks
Customers are usually responsible for locking their own storage unit. At Sentry Self Storage sites, you can purchase a variety of locks for your storage unit if you need one.
A strong lock adds another layer of protection, especially when combined with CCTV, controlled access, and alarm systems.
Alarm Systems
Alarm systems help protect storage facilities when staff are not on-site. At Sentry Self Storage, alarms are monitored 24/7.
Depending on the storage provider and facility, alarm systems may include building alarms, motion sensors, fire detection systems, or alarms covering key access areas.
On-Site Staff and Site Management
Facilities with staff on-site during opening hours often provide better oversight. Staff can monitor unusual behaviour, check visitor access, respond to customer questions, and help maintain site standards.
Some storage companies may use extra security measures at certain sites, but these can vary by provider. Sentry Self Storage does not use overnight security patrols, so customers should rely on the confirmed security measures in place, including 24/7 CCTV recording and 24/7 monitored alarms.
Can Storage Units Be Broken Into?
Break-ins can happen, but professional facilities are designed to reduce the risk through controlled access, monitored entry points, CCTV recording, alarms, and secure locking systems.
Security standards can vary between facilities, which is why it helps to compare access controls, lighting, monitoring systems, and site condition before booking. Reputable providers work hard to reduce these risks because security problems damage customer trust and reputation.
Factors that can affect storage security include weak locks, poor lighting, less monitoring, broken access gates, or unmanaged facilities with little oversight.
You can lower the chance of theft by taking a few sensible precautions.
Use a High-Quality Lock
Cheap padlocks are often easier to force open or damage. Many customers choose hardened steel locks or disc locks because they are designed with security in mind.
Keep Valuable Items Out of Sight
Avoid placing expensive items directly near the unit entrance. Cover electronics and valuables with blankets or plain boxes.
Choose a Reputable Storage Provider
Check online reviews, security information, and site photos before booking. A professional provider should clearly explain its security procedures, access rules, insurance requirements, staff presence, CCTV recording, and alarm monitoring.
Visit the Facility Before Booking
If possible, inspect the site in person. Look for clean surroundings, working security gates, bright lighting, visible cameras, and well-maintained buildings.
A poorly maintained facility may indicate weak management standards.
Are Storage Units Safe for Valuables?
Storage units can be safe for many valuable items, but extra precautions are needed depending on the item type and value.
Most people use storage for furniture, appliances, clothing, business stock, tools, documents, or household items. These belongings are usually well protected in secure facilities when they are packed properly and covered by suitable insurance.
Some valuables need additional care or may be better stored elsewhere. If you are unsure what to store, you can call Sentry Self Storage and speak to one of the branch managers for advice.
Items Usually Safe to Store
Furniture, home appliances, office equipment, seasonal items, business stock, and boxed household belongings are all commonly placed into storage units. Documents and tools are also regularly stored, particularly during moves, renovations, or office changes.
Sensitive items such as paper records, artwork, electronics, or wooden furniture may need extra packing care because temperature and moisture can affect them over time. Customers storing delicate items should ask the site team for practical packing and storage advice before moving in.
Higher-Risk Valuable Items
Items such as jewellery, cash, luxury watches, rare collectibles, family heirlooms, and certain legal documents may carry a higher theft or damage risk. Many storage providers recommend keeping irreplaceable or very high-value items elsewhere where possible.
Many storage providers advise against storing cash or irreplaceable valuables. Always check the provider’s restricted items policy and insurance terms before moving in.
How to Protect Valuable Items
You can improve protection by using sealed containers, wrapping fragile belongings carefully, and keeping an inventory with photos of valuable items. It is also sensible to avoid labels that advertise expensive contents and to check insurance requirements before moving items into storage.
If you plan to store high-value items, check the provider’s insurance limits and exclusions before moving in.
What Risks Should You Be Aware Of?
The main risks with storage units include theft, moisture damage, pests, and poor facility management.
Secure storage facilities reduce these risks, but no storage environment is completely risk-free. Knowing the most common problems can help you prepare properly.
Theft
Controlled access systems, monitored entry points, CCTV recording, and alarms can help reduce the risk of theft at storage facilities.
You can reduce risk by using a strong lock, avoiding obvious labels, choosing a reputable facility, and keeping expensive items hidden from view.
Human Error
Storage problems can happen when items are packed badly or placed in the unit without enough care.
Common mistakes include overloading boxes, using weak cardboard, storing damp belongings, or stacking items poorly inside the unit. Furniture that is not wrapped properly may also become scratched or damaged during long-term storage.
Careful packing helps prevent damage during long-term storage.
Moisture and Damp
Moisture can affect stored belongings if items are packed damp, left uncovered, or stored in unsuitable containers.
To reduce the risk, make sure everything is clean and dry before storage. Use protective covers for furniture, sealed plastic boxes for smaller items, and avoid placing delicate belongings directly on the floor where possible.
Pests
Pests are less likely in well-managed facilities, but food, crumbs, and poorly sealed boxes can increase the risk.
Do not store perishable food, plants, or anything that may attract pests. Clean appliances before storage and keep soft furnishings covered.
How Do I Keep My Items Safe in Storage?
You can improve safety by choosing the right facility and preparing your items properly before storage.
Good preparation lowers the risk of theft, damage, and moisture problems.
1. Choose a Reputable Provider
Look for storage companies with clear security information, modern facilities, staffed reception areas, transparent pricing, and positive customer reviews. It also helps to check insurance requirements before you move in.
Established providers often have clearer security procedures, staffed facilities, and more developed customer support systems.
2. Use a Strong Lock
A high-quality disc lock or hardened steel lock provides better protection than a basic padlock.
Avoid cheap combination locks that can be forced open easily.
3. Pack Items Properly
Use strong moving boxes, protective wrapping, and furniture covers where needed. Plastic containers can help protect against moisture, and pallets or shelving can keep belongings raised from the floor. It is also worth keeping heavier boxes at the bottom and avoiding overfilled containers.
4. Label and Organise Everything
Organised storage makes access easier and can help reduce accidental damage. Label boxes clearly, keep an inventory list, and leave enough room inside the unit to reach important items without unpacking everything. Frequently used belongings should also be kept near the front of the unit where possible.
5. Store Valuables Carefully
Place valuable items away from the entrance and avoid obvious packaging.
It is also best to avoid labels that clearly identify expensive contents, particularly for electronics, designer goods, or valuable equipment.
Are Storage Units Insured?
Most storage providers require or offer insurance, but the rules, cover levels, and exclusions vary.
Some facilities include basic protection in the rental price, while others require customers to arrange insurance separately. Sentry Self Storage requires insurance, so customers should make sure suitable cover is in place before storing belongings.
At Sentry Self Storage, customers can arrange insurance as part of the storage process. You can read the full details on the policies offered across Sentry sites on the insurance information page.
Before booking, check what is covered, what is excluded, and whether high-value items need to be declared separately.
