Comment: The two gentlemen who came to do the duct cleaning were absolutely professional and very pleasant individuals. Please pass on to their immediate boss how terrific I thought their work was. Together the two gentlemen assessed my 3-story condo, figured where to park their van to best reach the hoses and went to work. There was no dust floating around while their worked, all the vent grates and they cleaned the dryer vent without any issues. They showed me the camera visuals of my duct work. I am very pleased with the level of work and the professionalism of these two gentlemen. They represent Dalworth well and are the reason I will consider reaching out to Dalworth again for any future service work needed around my home. Thank you.
