I visited Dulles Sheet Metal at their location in Sterling City, Building 42722, Trade W Dr Drive, Suite 125. The company specializes in fabricating high-quality ductwork using only G90 metal, serving residential and commercial sheet metal/mechanical contractors in the Virginia, Maryland, and Washington DC area.The company's website mentions they accept debit cards and credit cards for payments, and their parking lot and entrance are wheelchair accessible, which is a plus.Their working hours are Monday through Friday from 7:00 AM to 3:30 PM, which is standard for most businesses.Despite the generally good impression, one thing that caught my attention was the reckless attitude of the company as shown by the ice flying off vehicles on highways, indicating a concerning lack of safety standards.Overall, Dulles Sheet Metal seems to be a reliable company with good quality work, reasonable prices, and a commitment to innovation. However, the safety concerns raised by some clients should not be taken lightly.
