Frequently Asked Questions
Many cast stone mantels are suitable for outdoor fireplaces because the material is durable and weather-resistant. In outdoor environments, sealing the stone may help maintain its appearance over time.
Each mantel is custom made to order. Once the design is approved and the deposit is received, your project is placed into our production schedule and we provide an estimated delivery timeframe. Because production timing can vary depending on current demand, we stay in close communication throughout the process and do our best to accommodate your preferred timing. Due to the size and storage requirements of cast stone mantels, we also coordinate delivery so the mantel can be shipped soon after it is completed.
Each mantel design includes dimensions for the overall width, height, shelf depth, and fireplace opening. Compare these measurements with your fireplace opening to ensure a proper fit. If adjustments are needed, interior panels can often be added within the opening to help customize the fit around the fireplace.
