I can't say enough about the Jim Gillespie and the way he runs Colbalt storage in Milton. The rates are very good. The facilities are always clean and secure. I recommend all my clients to Cobalt storage! Hand down!


Very friendly staff who are on call or on premises a majority of the time. Lots of security and a clean lot as well. Easy movement of my 24ft trailer in and out of storage with no clearance issues.


Clean facility and good service. Hidden just off Meridian so its out of sight.

John the property manager is great to work with and has been very accommodating and friendly. I’ve had storage units at other places before and the price and service I received from John and Cobalt Storage by far exceeds them all. I highly recommend using them!

Great manager John, he worked with me to get this done when I was in a last minute tight situation and he helped me make it happen. Great security, average price. Solid accessibility.

I love Cobalt Storage in Milton, the site is clean and well run. There is 24hrs supervision and surveillance there. The owner Jim also hosts rummage sales and tenants have an opportunity to get rid of un-needed items. Great access and service from Cobalt. Five Stars!!!

This storage facility is conveniently located near my home. The manager John was friendly and informative from the first time I called. It seems safe, lots of security cameras and motion detectors.

Originally I gave one star. But management called me and discuss with my one star feed back. Place is really clean. Great location. In house security. But each year price went up 20-25%. As your request (manager) I give 3 star. However each year 20% increased, I don't know how many people like to use this storage. After 2 year they stay same rate. Management said they work so hard to keep top level. I change 3 star to 5 Price wasn't best deal but security and maintenance are best.

I have been using Cobalt storage to park my travel trailer for the past few years. I like how convenient it’s been living just a short way away and more or less just around the corner. Currently, I am relocating my RV to Eastern Washington for family reasons and hate to give up my spot. Unfortunately, a guy has to do what a guy has to do.... I have really appreciated this management team quite a bit… John and his wife have been wonderful to work with and are always there when you need them. I have always appreciated how clean and well-kept the whole lot has always seemed to be when I am there picking up or dropping off my trailer. I have never had any negative feelings or experiences with this storage facility and hope to be able to use it again in the future.

Super service! John was great. This place had excellent security and the price was right. We only moved because we could get a space that was covered. John is the best!!

Great place to store your travel trailer, very secure place, the owners themselves personally run the business and very easy to work with. Wish there were more honest business people like the owners of Cobalt Storage.
