Large boulders may require professional assistance or heavy machinery to break them up safely and efficiently for removal. To do it yourself, use a masonry drill bit to drill holes into the boulder's surface at weak points or natural cracks. Once the holes are in place, insert metal wedges and shims. Then, strike the wedges with a sledgehammer to apply pressure and split the boulder along the drilled lines. It is vital to wear safety gear that protects your eyes, hands, feet, and body while performing this task.

First, most contractors will have a structural engineer create a report and plan for your project to ensure it’s safe to cut into the load-bearing wall. The contractor will then excavate around the wall, if necessary, measure the opening—allowing for additional space to fit and level the door, and then cut the doorway out. They will likely install a steel lintel as a header over the door for support. Once the doorway is cut out, they’ll demolish the concrete using sledge hammers and masonry chisels, clean up the surrounding concrete, and seal around the door with masonry mortar. 

The project could take anywhere from one to five das, depending on the extent of the removal. Capping a gas line can be done on the same day, whereas completely removing a fireplace and chimney can span several weeks. Talk to your pro about the timeline and potential obstacles, like fireplace material, location, and potential structural issues.

Chimney removal often requires at least two people. Removing a chimney stack is a long process because it must be done brick by brick. A full demolition typically takes up to five days, while removing a chimney stack only may take one-half of a day to two days.
