Common questions
Do I need a permit to remove an interior wall?
If the wall is load-bearing, yes — and you will normally need drawings showing how the load is carried afterwards. Removing a non-structural partition often does not require a permit, but whether a wall is structural is not something to judge by eye.
How do you keep concrete dust out of the rest of the house?
Concrete cutting and coring are done with water feed or dust extraction at the blade, and the work area is isolated from the rest of the building. This matters most on interior work, where the alternative is fine silica dust through the whole house.
Can you cut a concrete slab for new plumbing?
Yes. Slab sawing to a controlled depth is standard for running new drains or relocating plumbing in a basement, and the cut concrete is removed as part of the work.
What has to be checked before demolition starts?
What is inside the wall or slab — plumbing, electrical, gas, post-tension cables in some slabs — and what the element is carrying. Scanning before cutting is the difference between a clean opening and an expensive repair.
