I moved across the country and I needed a storage unit to put my belongings until I find my permanent home. Michelle helped me with the process and she is absolutely the best! A+Storage was the only easy process I had during my big move. Michelle went above and beyond, she was personable and kind. My friend and I were talking about her and saying “ wouldn’t that be great if everyone was like Michelle, or if she can show the other companies how to service their customers”. Thank you Michelle for making the stressful process easy for me! ... Read more

We rented a storage unit from A Plus Storage and had a great experience. The owner is easy to contact and work with.

Depending on what you need to put away in storage, you can discover there are some things you absolutely need, so make sure you check with the facility manager that you'll find everything you need on site.

This particular storage facility provides self storage units of different sizes, ranging from 50 to 480 square feet. Space is not an issue! If you have more belongings to store, or simply bulkier items or even vehicles, you should go for larger storage units.

You already know how much stuff you need to put in self storage, so figuring out the unit size you need is the next step. Smaller units such as 5'x5' or 5'x10' spaces can usually be filled with the amount of items you would normally store in a closet: a few chairs and lamps, sports equipment, garden tools and some boxes.

Moving on to larger sizes, imagine the 10'x10' and 10'x15' units as similar to a bedroom or a living room – larger pieces of furniture, sturdier equipment and bicycles can fit here. Finally, a 10'x20' unit has enough space for the contents of a 3-bedroom house, while the larger 10'x30' space easily accommodates the contents of a loaded semi-truck.

Accessibility and quickness are key when it comes to storage, so drive-up storage units are generally regarded as very convenient. Pull your car right up to your storage space, load, unload, and you're good to go! However, if you're mostly storing temperature-sensitive items, you should rather consider indoor storage units.

Climate-controlled units maintain consistent temperatures and humidity levels all year round, making them perfect for all your sensitive items. Moisture and varying temperatures can damage a whole host of things, and that is why a lot of people choose to use climate-controlled units to store items like wooden furniture, electronics, artwork, documents and photographs, collectibles, antiques, etc. If the belongings you're storing are important to you, you should consider renting a climate-controlled unit.
