How good is a commercial storage unit?

[Helen Patrick joey]

Hey all,

I just moved from Los Angeles to Windsor a couple of months back. This is my hometown. I had a small business back in LA which had a lot of office stuff like documents and other office goods. Now I don't have a proper space to store these things. These cannot be dumped in the backyard since it is damp. Recently our neighborhood caught on fire with ruining more than a couple of houses. Now I have to choose something which is waterproof and fireproof.
I have been looking to rent a commercial storage unit for just 2-3 weeks due to early closing. I remember seeing ads that say about fire preventive storage systems. How much effective are they? Anyone who has used it please reply.
