Caesar and his crew Julio and Michael were outstanding. They are hardworking and quite skillful in their craft. Kayden was also quite a delight to work with too. The employee at Tower Steel Buildings is what makes the company great, the upper management should take note.

I purchased a steel building from Tower Steel and was really glad I did. Every other company had sales reps that hounded me down, constantly came back with different pricing, selling me on buildings I didnt even want. Not with Tower Steel. The Sales Rep was very knowledgeable, they ensured the design was what I wanted, and being a Canadian company, their price in comparison was SIGNIFICANTLY lower than some of the competitors. If you're looking for a steel building that lasts forever, look no further. Guy the owner really looks to take care of his clients. Thanks Tower Steel Buildings!

Wasn’t sure about ordering a metal building online, but Danielle at Tower made it so easy. She answered all my silly questions without making me feel rushed, got me a good deal on a 40x60 for my equipment storage, and even followed up after delivery to make sure everything was okay. Super impressed with the service and quality. Definitely telling my buddies about this company!
