A: If the carpets had been new at commencement of the lease it would be fair to consider penalising tenants after 1 year if they didn't come up clean. New carpets have a form of protection shield, i.e. like a 'scotchguard' but, as we’re told, over time with cleaning they lose that protection and everyday wear especially in high traffic areas 'stains' that much easier and doesn't come out easily, or at all. This would therefore be considered fair wear and tear. Refer to our article for some good guidelines on "What is Fair Wear and Tear in a Rented Property."
