Commercial demolition work generally costs less than 2 percent of the replacement cost of the building. The ramifications of not dealing with a reputable, trained demolition contractor can be financially devastating. This is not the type of work where one gets a second chance. It’s important to look for experienced people who have the sophisticated staff and equipment to handle the assignment. The age of the structure, the amount of Salvage it will yield, and the manner of demolition chosen will also have an impact on the cost.
