Ventilation grilles are necessary for a fireplace surround to ensure proper airflow and ventilation. Without ventilation grilles, heat and smoke can become trapped, leading to potential fire hazards and poor air quality. Additionally, ventilation grilles help to distribute heat evenly and prevent overheating of the surrounding materials. Therefore, it is important to include ventilation grilles in a fireplace surround to ensure safety and functionality. **

To repair cracks in a marble fireplace surround, you can start by cleaning the area with a mild soap and water to remove any dirt or debris.

Once the repair is dry, you can use a fine-grit sandpaper to smooth out the surface and then polish the area to match the rest of the surround. If the cracks are extensive or the damage is severe, it may be best to consult a professional for repair. **
