Doorway Cutting in Concrete & Masonry
New Doorways Cut Through Concrete & Masonry Walls
CanaCore coordinates verified contractors to cut new doorways through concrete and masonry walls — precisely sized openings carried by an engineered lintel or beam above, with CanaCore field supervision.
What Are Doorway Cuts?
Doorway cuts create new door openings in load-bearing concrete or masonry walls. This specialized demolition service uses precision cutting equipment to create clean openings without damaging the surrounding structure, followed by installation of engineered support beams. Every doorway cut requires structural engineering to design proper support systems, building permits for safety compliance, and skilled execution with professional concrete cutting equipment. The result is a code-compliant opening ready for door installation.

“We needed a new doorway cut through our basement foundation wall for a walk-out entrance. CanaCore handled the engineering, permits, and cutting. The opening is perfectly square, they installed a strong steel lintel, and the city approved it first try. Now we have beautiful patio doors where there was just a concrete wall!”

Common questions
Can you cut a new doorway through a concrete or block wall?
Yes — a new doorway can be saw-cut through concrete or masonry to clean, straight edges. If the wall carries load, a lintel or beam over the opening is sized and installed so the wall above is properly supported.
Does adding a doorway need a permit?
Cutting into a structural wall generally does, because it changes how load is carried, and drawings showing the new opening and support are prepared for permit review. A non-structural partition is a simpler case, but whether a wall is structural is verified first.
How much mess does cutting an interior doorway make?
Saw-cutting concrete or block produces dust and slurry, so the area is contained and water feed or extraction is used to control it. The removed section is taken out cleanly rather than broken up, which keeps the surrounding wall and finishes intact.
