Cement Siding Siding Project in Chelmsford. This customer was dealing with lots of peeling paint and rotted wood. They were sick of having to repaint their wood siding every 3 or 4 years. We replaced old cedar clapboards with FC pre-painted fiber cement siding. We also replaced much of the trim with Cellular PVC, also known as Azek. The color of this Cement Siding and FCShingle is Boothbay Blue. If you live in Chelmsford or any other city or town in Eastern New England, we’d be happy to help you explore different siding options for your home.
