Egress Window Cutting

Building codes require that every basement bedroom have an egress window large enough for emergency escape and rescue access. Creating an egress window opening in a poured concrete or block foundation wall requires professional concrete cutting equipment and expertise. REDCORE provides egress window cutting services throughout Massachusetts, creating precisely sized openings in foundation walls that meet code requirements for minimum width, height, and sill height specifications.

A standard egress window opening must provide a minimum of 5.7 square feet of clear opening area, with a minimum width of 20 inches and a minimum height of 24 inches. The sill height cannot exceed 44 inches from the finished floor. REDCORE cuts openings to these exact specifications or to the custom dimensions required by the specific egress window unit being installed. Our wall saws and hand saws create straight, square openings with clean edges that accept window frames without extensive finishing work.

The process begins with careful layout of the opening on the interior wall surface, followed by wall sawing to cut the perimeter of the opening. The concrete section is then removed safely and the opening edges are cleaned up. For block foundation walls, we use hand saws to cut through the CMU and mortar. REDCORE coordinates with general contractors and foundation waterproofing companies who handle the window well excavation, drainage, and window installation.
