01.
While standard padlocks are common, we highly recommend using a disc lock (sometimes called a cylinder lock). These are specifically designed for storage units; their unique shape makes them nearly impossible to cut with bolt cutters, providing an extra layer of physical security for your unit door.
02.
Before you close the door, take a quick photo or video of the items inside your unit. Having a visual record and a written list of your belongings—including brand names and serial numbers for electronics—is the best way to stay organized and is incredibly helpful for insurance purposes.
03.
Protect your items from the ground up. Store your most valuable items toward the back of the unit and keep them off the floor using pallets or plastic shelving. Always use high-quality packing tape to seal your boxes tightly, which prevents dust from entering and keeps your belongings in “like-new” condition.
Established with a deep commitment to the local community, our facilities prides ourselves on offering a personalized touch that only a family-run business can provide. By combining years of industry expertise with a focus on customer satisfaction, we have created a storage environment that feels less like a corporate warehouse and more like a helpful neighborhood resource.
“I’ve used several storage places over the years, but MANWARREN Mini Storage is by far the best. The 24/7 high-definition camera protection gives me such peace of mind knowing my family’s heirlooms are actually being watched. The facility is clean, well-lit, and I feel completely safe even when I stop by later in the evening. Five stars for security!”

“You can really tell this is a family-owned business. Travis and the team actually care about their customers and are always available to answer questions. It’s so much better than dealing with a giant corporate call center. If you want to support a local Spencer business that treats you with respect, go here.”

“Moving is stressful enough, but the drive-up access here made unloading our entire house so much easier. We were able to pull the truck right up to the door and save our backs! The month-to-month leasing was perfect for us since we weren’t sure exactly how long our closing would take. Highly recommend!”

“I use MANWARREN for my business inventory storage, and it’s been a game-changer. The units are dry, structurally sound, and extremely easy to access. Having a large commercial-sized space right here in Spencer saves me so much time and money. Professional, clean, and very secure.”

“I was impressed by how clean and well-maintained the property is. Some storage lots feel run-down, but Manwarren looks brand new. The doors open smoothly, the pavement is clear, and it’s obvious they take pride in their facility. I wouldn’t trust my furniture anywhere else in the Lakes Area.”

“Best storage value in Spencer, IA! For the level of advanced security and the quality of the units you get, the prices are very fair. There are no hidden fees or long-term contracts you can’t get out of. Simple, honest, and high-quality storage—exactly what I was looking for.”

Self storage is an affordable, efficient way for you to store your life’s possessions. There are many reasons you might need a storage unit, whether you’re moving or downsizing, or have a growing family. You can even store cars and motorcycles at some facilities. Self storage makes it easy to store items of all shapes and sizes in one convenient location.
At Manwarren Mini Storage, we offer a wide range of sizes to accommodate your storage needs. To better visualize what is the best size unit for your needs, reach out by clicking here to see our current available sized units and one of our Storage Advisers/Managers will be happy to assist you!
The amount of time you’ll need storage depends on your situation. You can reserve temporary storage for a move, or long-term storage if that better fits your needs. We offer month-to-month leases so you have the flexibility to move in and out when the time is right for you.
Unfortunately, we currently do not allow any food, beverages, or perishables to be stored inside of the storage units.
Roll-up doors are very similar to garage doors and are accessed by sliding a latch and lifting the door upward. Roll-up doors are typically bigger than most doors, allowing tenants to easily move in and out of the storage units.
Yes, we serve many business clients who need secure storage for files, equipment, inventory, and promotional materials. Additional services like package acceptance and shipping are available.
