good experince of the after sales service
I had done duct cleaning with the double diamond. I was not happy with the first service. But the owner had contacted me after wards for the customer satisfaction survey courtesy call and I told him the truth. He came for visit next day and day after he almost redo the whole job by himself. He had gone beyond for that extra mile which would satisfy you of making right choice. I would say they have good working ethics. When you call, ask for Phil.
