4.5/5 - 228 Reviews

Read some helpful reviews of Sound Storage of Mill Creek at 4012 148th Street SE, shared by real renters with genuine experiences and honest opinions.

Easiest move into storage ever! Extremely nice and helpful staff in the office too! I chose this location because it was one of the few places I could get a 10x5 instead of 5x10 unit. I'm not in the best shape physically, so trying to go 10 feet deep into a locker is not feasible. I can already tell the 10 x 5 is going to be perfect for my needs. When you rent an apartment, they just don't have enough storage space. So I need a locker that's like an extension of my home. I am already impressed with the cleanliness of the facility and helpful office staff AND the hours. Some places are closed on weekends or Sunday, and that's about the only day I can go. I can already tell I won't dread visiting my locker like I did other places, but look forward to accessing it whenever needed. ... Read more

I worked with Karen and she was so lovely. She helped us get a great unit and was so helpful. I saw first hand how hard she works to keep everything running smoothly and safe. It made me feel better knowing my items were left in good hands. ... Read more
Desiree L. - 7 September 2025
BEWARE! THEY'LL INCREASE FEES SEVERAL TIMES IN A YEAR and IMPOSE INSURANCE WITHOUT NOTICE or consent. BILL WENT FROM $35 PROMO TO $108. 300% INCREASE! I would do 0 stars if I could. Talked to Karen today to whom I questioned how they had my same unit listed for $24 right now, yet I'm paying $108. She said that rate was just to get people in the door (trapped basically) and that everyone would eventually end at the same ridiculous rate I have. Needless to say, she was not helpful, did not offer any alternatives (per what's mentioned in the business reply below) and made me feel like I'm being ripped off l, like it or not. Only alternative she offered me was to vacate. DON'T TRUST THIS BUSINESS. You can see in all of my reviews I'm generally a happy customer but this abusive practice makes me angry and won't be silent. (Previous review) I have a 5x5 unit that I got at 35 dollars for the first 2 months, then I started paying 70 and a a couple of months later I saw it was $85. I called and they told me I was obligated to pay insurance, hence the 85 instead of 70. I told them I don't need to insure any of the items I have in there and they said it was mandatory SO they added their insurance. NOW IT'S $108! Again No warning, etc. My payments are auto so it's done. And the crazy thing is that they still have the same size unit listed for $35 a month and 69 after (don't fall for that if you are reading this). I hardly ever give this sort of review, this one is well deserved. This is an abusive and very shady practice that I won't tolerate. Getting my things out ASAP. Very sad I put my trust in this business. ... Read more

The best storage in the area. Clean. Aircondition. Access time is convenient. Office hours is the best. Very friendly staff. The only drawback is... the rate! Introuctory price is reasonable until they hike it to very unreasonable. ... Read more

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.

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!
