We encourage you to do your own research on the best storage in San Mateo. Some companies may advertise the “cheapest storage in San Mateo” and offer all or part of the first month “free”, but you’ll actually end up paying more in security deposits and random admin fees. Plus, your rates may be managed by software that automatically increases prices to match the market, sometimes many times a year! Always ask for the total out-of-pocket price before you sign a contract. We have no deposits and no hidden fees; what you see is what you get—the quote you see online or by calling our manager is what you pay! 

The reason Security Public Storage is usually in the top 3 storage companies on Google, Yelp, and other customer review sites is that we really deliver on our promise to provide safe, clean, secure facilities. Our managers actually live on the property in order to provide best possible customer service and security. We invite customers who are shopping for storage in San Mateo to read our customer reviews on Google and Yelp, and to actually check with the local police department. We have such a strong security and safety record that many local police and firemen store with us. Now that’s a strong recommendation!

Security Public Storage at 110 E 25th Avenue really does offer you the BEST VALUE storage in San Mateo. Our storage units are within a mile or two of Bay Meadows, San Mateo Public Works Dept., San Mateo County Event Center, Peter Pan BMW & Hillsdale Shopping Center. Plus we have a great selection of storage boxes, locks and moving supplies.
