I simply want to say it's refreshing to deal with a true professional as Ralph at the Lewisville location. Im retired 31 yr aircraft inspector for American Airlines and its refreshing and just wanted to say I appreciate being treated as such. ... Read more

Extra Space took over the unit and raised the rate to $116 w/insurance for a 10x10 in June 2025. We took a web rate promo and downsized into a 5x10 then, first full bill was $51, which is like $40 plus insurance. Now we get a postcard that our rate will go to $80 plus insurance in October 2025. If you would like your rate to double in 4 months, this is the place. The nerve it takes for these millionaires to charge more per square foot than my home for their drafty house of cards. I'm sure they would blame the market, but "Timmy can do it so why can't I" is the defense of a child. You're ripping people off. We will downsize again and get out of the unit. EDIT: The onsite manager, Ralph, was very courteous in giving some relief on this rate increase, probably temporary but it is appreciated. I will say that the local staff have been great, but the storage prices set by extraspace and others in this area are getting out of hand and are in need of a correction, especially if they are giving themselves opportunities to increase rent 3 times a year. ...

Absolutely top-notch customer service! I had a great experience with SteelCreek storage from beginning to end. I did everything online and was able to access my unit same day after office hours. Also, I forgot to mention they provide a lock. From the moment I inquired about a unit, the Ralph went above and beyond to make the process smooth and stress-free. He was friendly, professional, and incredibly responsive—answering all my questions and helping me access unit. The facility is clean, secure, and well-maintained. I’ve used storage services before, but none have matched the level of care and attention I received here. Highly recommend if you're looking for a place that truly puts customers first! ... Read more

I had a great experience with Steelcreek Storage from beginning to end. I started the initial rental process online. Their website was easy to maneuver, and the information provided was clear, making the selection of my unit a breeze. As soon as I submitted my application, I received a text from Ralph who gave me further instruction for completing the rental process. I was not able to get into their office until almost closing time, but Ralph was there waiting with a welcoming smile and friendly demeanor. Despite it being past closing time, Ralph took me to see my storage unit and answer any questions I had. A big thank you to Ralph for accommodating my schedule and staying after hours to get me set up and acquainted with the property. I really appreciate that. Your customer service was 5-star!! I would hands-down recommend Steelcreek Storage to anyone looking for a pristine climate controlled storage unit in the Lewisville area. ... Read more

This is a great storage facility, very clean, and continually making improvements. Ralph is a huge help whenever I need something. Maintenance requests are taken seriously and acted on quickly. If the interior of your unit is impacted, they video the work from opening door to closing it, though no issues at all the one time my unit needed something inside. The availability of a climate controlled unit with direct exterior access seems unique to this facility. Will use this facility as long as I need a storage unit. ... Read more

I happened upon Steelcreek Storage on my way to another Storage facility, so I quickly googled the property information and stopped by. I needed to rent a unit and begin moving things ASAP. Ralph was awesome sauce and super sweet! He helped me choose the best size for my items, walked me through the unit, and I was pleasantly surprised by the monthly rate. The process was simple & quick, and Ralph made sure my access code was working before I came back later that evening to drop off my first load. The property is very clean, well lit at night, and I felt perfectly safe. I had a great customer experience and highly recommend Steelcreek Storage. ... Read more

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 25 to 517 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.

Monthly prices for units offered by Extra Space Storage - 940 North Mill Street start from $46 and can go up to $416 for larger spaces.

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.
