“We set out to revitalize an existing office building with a dilapidated look and reputation, into a hallmark Silagi Development property. We understood that this was no small undertaking and knew that no ordinary contractor would suffice. JHL stepped up to the plate, exceeded expectations with regard to quality and safety, and completed the job in considerably less time. Silagi Development will without a doubt use JHL Constructors for any of our future Colorado projects.”
