Comment: I may need several spots in the hall to be re-treated after Thanksgiving. This was not the fault of the technician. They just need a second treatment. I think I tracked something inside after working in the yard. I am always pleased with the Dalworth Clean quality of service. The technician arrived a few minutes before 9:00. My window was 9-11. He was not only prompt but he took his time and wanted me to be satisfied with his work.
