The only time a landlord falls under a duty replace a tenant's carpet is if the condition of the carpet affects the safety or health of the tenants, such as if the carpet has become moldy or if it has holes or rips. No duty to replace arises based upon mere age or appearance.

If the carpet has been present for more than twenty-five years, so has the matting. As for the carpet's being dirty, dirty carpets can be vacuumed or cleaned.
