I purchased a voucher on Buytopia for duct cleaning services with Diamond Duct Cleaning. We recently had major renovations in our home and needed to ensure that our ducts were cleaned for the winter. Diya and Aiman scheduled the duct cleaning for a Saturday, which happen to be during the long week end. They both showed up on time, installed their equipment, explained what they were doing, took before and after pictures. They worked as a team, professionally, clean and very well coordinated, not loosing time for small talk. We end up even asking them to perform more cleaning than we initially paid for, without feeling that we were dealing with sales people. We are very happy with the way we were treated as customers, for the quality of their job, their professionalism and honesty. I would warmly recommend Diya and Aiman - Diamond Duct Cleaning. Thank you, Diya and Aiman.
