If any estimates of how long it will take the cleaning operatives to complete the job are being provided those are only estimates based on the average time it takes to clean a home or an office of similar size to the Client’s, it being difficult to calculate precisely how long such tasks may take and that a degree of flexibility may be required. Please note that one off cleans may take longer to complete due to longer intervals between cleaning sessions, number and type of cleaning tasks required, when compared to the regular maintenance cleaning of the same property.
