Egress Window Installation in Sioux Falls, SD

Transform Your Basement into a Safe, Legal Living Space

In Sioux Falls, an egress window is one of the smartest investments you can make for your home. Not only does it flood your basement with natural light and fresh air, but it also provides a critical life-saving exit in the event of an emergency. At Mullen’s RPM, we specialize in the professional installation of code-compliant egress window systems that meet all local and state safety regulations.

By installing a legal egress window, you can officially market a basement space as a bedroom, instantly increasing your home’s square footage and resale value. Whether you are finishing a basement in Sioux Falls, Brandon, Canton, Harrisburg, Lennox, Tea, Hartford, Renner, Lincoln County, and Minnehaha County or retrofitting an older home, Mitchell Mullen handles the technical excavation and structural cutting with precision.

Why Your Sioux Falls Home Needs an Egress Window

Adding an egress window is a major project that requires more than just a handyman—it requires a specialist who understands the “RPM” (Remodeling & Property Maintenance) of your foundation. Our services include:

  • Foundation Cutting & Excavation: Precision diamond-blade cutting through concrete, block, or stone foundations without compromising structural integrity.

  • Code-Compliant Window Fitting: We ensure every installation meets the 5 sq. ft. net clear opening requirement mandated by Sioux Falls Building Codes.

  • Custom Window Well Systems: Installation of high-quality, durable wells (steel, composite, or stone) with integrated safety ladders and proper drainage.

  • Moisture & Drainage Control: We connect your new window well to your home’s existing drainage system to prevent water intrusion and mold—a critical step in the South Dakota climate.

  • Safety Covers & Grates: Adding heavy-duty, child-safe covers that keep out debris and animals while remaining easily operable from the inside.

Understanding the 2026 Sioux Falls Egress Requirements

We take the guesswork out of compliance. To be considered a legal emergency exit in South Dakota, your window must meet several strict criteria:

  • Minimum Opening Area: 5.7 square feet of clear space (5.0 sq. ft. for grade-floor windows).

  • Minimum Dimensions: At least 24 inches in height and 20 inches in width.

  • Sill Height: No more than 44 inches from the interior floor.

  • Operation: Must be operable from the inside without the use of keys, tools, or special knowledge.
