Accessories Mantels Builder’s Fireplace has noncombustible mantel options in several styles. They are made of either cement, metal, or cast stone. Chimney Caps A chimney cap or termination can be used to keep the critters, leaves and weather out or simply give a fresh look to chimney. We also offer caps that incorporate dampers if your damper at the fireplace has been compromised. Shrouds Chimney shrouds offer the opportunity to shield any unsightly chimney terminations or caps and improve the overall look and architecture of a chimney. We offer semi-custom and full custom options to achieve this goal. Doors & Screens Doors and screens are available for prefabricated units and custom masonry fireplaces. They can be customized to fit any style by choosing from many options of different glass colors, finishes, styles, handles, and more.
