Egress Window Cutting in Bismarck, ND
Cutting a code-sized opening into a poured or block foundation is the one step of an egress project homeowners shouldn't take on themselves. We connect you with a local crew that wet-cuts the opening square and to size — meeting the 5.7 square foot ND requirement the first time.
-
Layout & sizing
The opening is sized to code from the window spec.
-
Wet cut
Clean saw cut through the foundation wall.
-
Structural support
Header and support installed above the opening.
-
Cleanup
Concrete removed and the site cleared.
Why the cut is the step to hire out
A foundation wall is structural. Cutting a hole in it means accounting for the load above the opening — which can call for a lintel or header — and for what's inside the wall itself: poured walls commonly carry rebar, and hitting steel with the wrong blade turns a clean cut into a ragged one.
Get the cut wrong and the failure modes are expensive: cracking that spreads from a stressed corner, an opening cut out of square that the window can't seal against, or water intrusion where the cut meets the well. The saw rental itself runs roughly $100–$300 a day (national rental-rate data), but the risk you're renting along with it is the real cost.
Poured vs. block foundations
Poured concrete is one continuous structural pour, so the opening must be cut with a diamond-blade saw — slower, more equipment, and typically the higher end of the price range. Many Bismarck-area homes, older and newer, are poured.
Concrete block comes apart unit by unit, which is faster — but block walls have their own trap: the cores may be hollow or grouted, and the courses above the opening still need support while the header goes in. Different wall, same conclusion: this is measured structural work, not demolition.

A crew that cuts egress openings every week will: verify the opening size from the window's net clear opening requirement backward, wet-cut to control silica dust, support the structure above the opening, and plan the sill height so the finished window sits no more than 44 inches off the floor — the number the final inspection checks.
Permits still apply
Cutting a new egress opening in Bismarck is permitted work. Most residential permits are issued within one business day, and the project passes a framing and a final inspection before it closes. The process and fee math are on the ND egress code guide.
