“We were so pleased with our experience with Regency Steel Buildings. Dillon was a wonderful sales rep and went above our expectations to make sure we got exactly what we wanted! Will definitely recommend!”

“Despite a few delivery timeline setbacks due to COVID caused supply chain issues, I had a great experience with Regency and my sales associate Ryan. The company maintained constant communication, transparency and went the extra mile to ensure the building materials were delivered. They even took the extra step to coordinate with my installer. I couldn’t be happier with the quality of the building and I am sure it will be standing and functional for many decades to come. Thanks again Regency and keep up the great work!”

“Jeremy and his crew were fantastic; everything was done on schedule, and exactly as the plans were drawn up. If I ever decide to add units to my mini-storage business, I will be calling Regency.”

“Great buildings and were great to work with throughout the process of picking out size, options & colors. I have 2 buildings from Regency Steel buildings and Dillon Cowles was my go-to for each building!”

“I had only been in the storage business for about a year before I decided it was time to add on. Called Regency and talked to Jeremy, he was great help. Since this was my first new building he had all the answers. Sent me some drawings, a quote an we placed an order. Contractor really liked the plans an the building quality. If I expand again I’ll use regency again..”

“In 2019 I worked with “Jeremy” at Regency Steel Building Supply. He was very beneficial from the start and throughout the process. Once he was provided with my site plan and building request he quickly responded with building designs for my project. Do to the slope of my work site I had to change all of the building’s designs. Jeremy again responding in a timely manner, working with my architect, engineer and myself to come up with a set of prints that were perfect for my site. Once the plans were approved, Regency shipped on time and had the entire package onsite ahead of schedule and without damage. During construction I had an issue with one of the roll up doors. One of the tensioners that hold the door in place failed. I called Jeremy and he went to work contacting the door manufacture and getting a replacement part without holding up my contractor. In short I was very happy with Regency Steel Building/Mini Storage Outlet. The price with right, the service was excellent, and the follow-up made my entire project run smoothly.”

“We (general contractor) constructed a ~ 100 storage unit bldg that we procured from Regency through mini storage outlet and the whole process was great. Their sales/design team did a great job working with us and handling any issues (minor) that came up during construction… will continue to do business with them.”

“Bought a building package from Regency. Had some difficulty finding a contractor to put it together. With little experience, decided to do it myself ( with some extra helping hands ). The quality of the package was great. When I needed customer support, they were easy to reach and helpful.’

“First time Storage owner undergoing a significant expansion. Dillon was great and worked with me from design to build out. Very quick responses on my inquires and exceptional experience. Regency offered the most competitive prices, delivered the highest quality systems and the best customer service. I will use Regency for future projects and recommend Regency to anyone building or expanding a Storage facility!
Thanks for your support Regency!”

“My experience with Regency has been real good! The buildings are good quality and fit together real good. The staff is super helpful. Thats why I have another building arriving day after tomorrow!”

“I purchased several buildings from Regency for my storage facility. The order process was easy and everything arrived when it was supposed to. It was a great experience dealing with them. I would definitely use them again.”
