Apart from the regular deep cleans, maintenance checks should be performed every few months to detect damage due to wear and tear over time or environmental factors like weathering. Make sure that doors are properly locked to ensure tenants feel safe in their homes. Replace smoke detector batteries if necessary to keep them in good condition. It is important to keep apartments smelling fresh. Empty trash cans regularly and replace any old air fresheners that have lost their fragrance. Dust hard surfaces such as furniture tops and window sills regularly to prevent dust buildup. This is due to the weight of the material which attracts particles quickly.
