Secure Storage Units in Charleston

Big Bertha Storage is a brand new storage facility, fully equipped with modern and updated storage units. At a great price you’ll be able to safely store away household items, furniture, clothes, seasonal items, and much more. Each unit is 100% secure and enclosed inside of our facility, which is under video surveillance 24/7.
Our temperature controlled units also ensure the protection of your items since they’re kept in stable temperatures year-round. These units allow you to store your most valuable belongings without fear of mold, mildew, rust, corrosion, water damage, or other potential damage from pests or unpredictable temperatures. For easy loading and unloading use our cargo elevator, drive-in loading area, dollies, and carts.

Big Berth Storage has exceeded my expectations in every way. I have stored antiques, art work and furniture at several other storage companies around Charleston. None compare to this. The owner/operators are accommodating and the location is clean, well lit and safe. Plus I can drive there in less than 10 minutes from my house. It's the best decision I've made all year.
