Restoration and Repair of Historic Cast Stone and Decorative Trim

Cast Stone (sometimes labled 'PreCast') is the cost-effective substitute for hand-carved natural stone developed at the beginning of the 20th c. As Portland cement became more available towards the end of the 19th century, its use as an alternative decorative building material became more prevalent. Given California's major surviving buildings date from after 1900, it is no surprise that there are multiple examples of cast stone restoration and repair projects for our review.
