Skylights, like everything else in your home, require maintenance. If you do it right, your skylights remain intact for years. Here are a few care tips. 1. The interior and exterior surfaces of skylights need thorough washing and cleaning twice a year. However, do it on a cloudy day because the cleaning solution could streak the pane on a sunny day. 2. Make sure that you follow all safety precautions while cleaning. Use a safe ladder and do not attempt it when you are alone at home. 3. Follow instructions given on the packaging of cleaning materials. 4. Use a soft sponge and good quality materials for cleaning. Rough sponge and poor quality cleaners can scratch and ruin the skylight. 5. Clean in a single direction and clean all the panes evenly. 6. Use materials that are suitable for your skylight. For example, glass cleaners are not recommended if your skylight is made up of plastic. 7. Do not leave residue moisture on the pane after cleaning. Wipe it dry using a soft dry cloth. Be more careful if the skylight is horizontal. 8. Inspect the skylight after every season to identify signs of damage. Be very keen on observation after windy storms, rains and hailstorms. 9. If you identify cracks or breaks and excessive leakage, replace the skylight by hiring a professional.
