Climate-Controlled Storage Units in Seguin
Are you storing items that may be sensitive to temperature or humidity? Do you plan to store for more than a couple of months? In either of these cases, we recommend one of our indoor climate-controlled storage units. These units feature indoor access in a building protected by fire sprinklers.
The interiors feature controlled temperatures with milder humidity levels, making them ideal for long-term storage. They’re also better for short-term storage of clothing, electronics, furniture, instruments, documents, and many other common items.

Leave the unit empty, swept clean and unlocked by midnight on your move-out date to get your security deposit back.
Do I need insurance?
Yes. The lease requires coverage for your belongings. Add tenant protection at checkout, from $12 a month, or use your own homeowner’s or renter’s policy.
