Customer Feedback
AA Garza
Working with Sylwester and his team at ProSteel was a joy from start to finish. Their attention to detail and expertise made the whole experience lacking in the stress often associated with home renovations. The installation was perfect, done by people who clearly take pride in their work. And there was no mess left afterwards either - only beautiful custom-made steel and glass doors.
Nick Rengers
Great company to work with and Sylwester was really able to transform our ideas into wonderful doors from steel. The result is even better than expected! High quality and great attention to details! The installation was done with the highest care possible. Really careful with drilling and they cleaned everything. From a level that you do not see often! If you are looking for hand-made doors from steel ProSteel is the company to contact. We can definitely recommend it.
