Fiber-cement board is a composite of sand, cement, and cellulose fibers. It is stronger than aluminum and vinyl. It is naturally resistant to mold, mildew, and fungus unlike basic wood siding. It is fire and flame resistant.  We remove old siding prior to installing fiber-cement board. This process can make it more expensive than vinyl and steel. Fiber-cement board comes in a variety of factory pre-finishes but also allows the customer to paint the product. Painting is an option with fiber-cement that is not available to steel, vinyl, and aluminum siding. Minimal maintenance of paint and cleaning may be necessary. Fiber-cement board comes with a limited 30 year warranty.
