Read some helpful reviews of Maple Valley Storage at 26039 Maple Valley Black Diamond Road SE, shared by real renters with genuine experiences and honest opinions.

Been at this location less than a year b/c it was affordable compared to the other place we were using. They raised the rent for both our storage unit & RV storage 30% without notice. This is ridiculous. We will be finding another location. ... Read more

JUNK YARD! With the dumbest manager you will ever meet. Moving in less than a year ago was a huge hassle and they kept trying to overcharge us, spent countless hours chatting and on phone to correct. Here less than a year and we get notice our rent is going up 50 a month but when you go online the same units are going for 50 less a month. Gave notice of move out and they are still trying to charge me. FIND SOMEWHERE ELSE, THIS PLACE IS HORRIBLE! ... Read more

Here less than 1 year(8 months) and we get a notification that they are raising rent. So we find an another place that's gonna save us $100 a month and does pest control(this place has tons of rodents fyi), and they won't reimburse the rent I paid for this month. I was told when I went in last time that it would be. Leaves a bad taste when people are comfortable keeping money like that. Won't be back and won't recommend. ... Read more

It's a great place, good location and very secure, we've used them for tha last 15 years, never had anything messed with or stolen, unfortunately their space rent prices continue to climb and I can no longer afford it, so this my last couple months with them. I recommend em though if you need a good secure place to store your items, I used the outdoor rv space for the majority of the time, they offer several different size lots or units, indoors or out ...

Over the past 10 years I've rented two storage units plus a parking space for my RV. Everything is very clean and secure. Service always has been friendly, helpful, professional. Completely pleased, zero complaints. Look forward to using them again ?? ... Read more
Jim H. - 6 April 2025
Getting the storage unit was simple. I did it all online and it only took a few minutes. Even got the first 2 months at a nice discount doing it online. Then I went to the mini storage location and got my access code and finished the process. The lady there was very nice and finished the process quickly. ... Read more
Vic B. - 1 February 2025
Worst storage unit ever! They doubled the price I was paying within a 3 year time frame. It went from $90 to $180. The office lady was so rude when called and told her we wanted to cancel. And continued to be rude until we moved our stuff out. This place is a complete joke! Don't rent from here unless you want to get ripped off on price and by thieves that break into units on a regular basis. ... Read more

Terrible customer service and lack of professionalism. Moved out on Feb 18th and notified office I had taken my lock off. Although there is a 30 day notice they would not give me a receipt that I was out and lock off. They said they would pro rate but billed me for full month of March, $336, outrageous. Still have no paperwork saying I moved out. Called corporate and customer service, Grant said they should have vacated me. Still no paperwork. Terrible business. If I could give a negative number in rating I would. Interesting they have a lock on the space they say I have till March 10th? Did they rent it out on my dime? Definitely not an honest business. Beware! ... Read more

Frequently Asked Questions

There is a wide array of amenities available for the storage units that Maple Valley Storage - 26039 Maple Valley Black Diamond Road SE has to offer. These amenities include Indoor, Drive-Up Access, Retail Available, Truck Rentals, Security Camera, Gate, Parking, Credit Cards Accepted, Online Payment and RV Storage. Most of these amenities can prove to be very useful depending on what you need to store. For example, climate-controlled units can come in handy for keeping sensitive items, drive-up access can make your loading and unloading process easier, and extra security measures will ensure your items are kept safe at all times.

The storage units offered by Maple Valley Storage - 26039 Maple Valley Black Diamond Road SE can satisfy all of your storage needs. Different sizes here range from 50 to 595 square feet. You can go for smaller units if you don't have a lot of items to store, while choosing a larger space is recommended in case you need to store a lot of furniture, bigger items or even vehicles.

The unit size that you should choose obviously depends on how much stuff you need to store. On the one hand, you should think of smaller units (5'x5' or 5'x10') as closets – they can be used to store chairs, lamps, moving boxes and sports equipment, along with smaller pieces of furniture, books and documents.

On the other hand, the 10'x10' and 10'x15' spaces are good for storing larger items of furniture, bicycles and a larger number of possessions. If you need even more space, then 10'x20' and 10'x30' units can easily accommodate the contents of an entire 3- or 4-bedroom house.

Storage units offered by Maple Valley Storage - 26039 Maple Valley Black Diamond Road SE come at a variety of prices, starting from $42 per month for typically smaller units. However, larger spaces can set you back up to $357 a month.

We know that when it comes to self storage, there is nothing more important than quickness and accessibility. Drive-up access is an extremely convenient amenity, as you can park your vehicle right next to your unit, making it significantly easier to load and unload the items you will use storage for. However, drive-up storage units tend to be outdoors, so you might consider indoor storage spaces with climate control if you're looking to keep temperature-sensitive items in peak condition.

Yes, you might, depending on what you need to put in storage. Climate-controlled spaces keep temperatures and humidity levels consistent all the time, which means they are perfect for storing sensitive items. Seeing that a whole host of things can be damaged by varying temperatures and excessive moisture, many people choose to rent climate-controlled units for personal items such as documents, photographs, paintings, collectibles, electronics, wooden furniture, antiques and even vehicles. If you're looking to store such items that are valuable to you, consider renting a climate-controlled unit!
