Egress Window Installation (Basement + Bedroom)

Egress windows are emergency-escape-and-rescue openings required by NJ Uniform Construction Code (R310) in every sleeping room below the fourth story. R310 requires minimum 5.7 sq ft net clear opening (5.0 sq ft grade-level), minimum 24" opening height, minimum 20" opening width, and maximum 44" sill-height from finished floor. Basement bedrooms below grade also require window wells with permanently-affixed ladders. We install code-compliant egress windows in NJ residential — typically casement style (which provides full-sash opening to meet R310 in smaller rough openings) — plus full window-well installation with proper drainage + cover when basement sills are below grade. Common scenarios: basement finish creating a bedroom (egress mandatory + window well required), pre-1980 bedroom replacement that triggers R310 retrofit, addition that creates a new bedroom. We handle the permit, the structural framing assessment, the window install, and the inspection coordination. Typical egress retrofit (window + window well + ladder + drainage) runs $3,500-$6,500 installed; bedroom egress retrofit without window well runs $1,500-$3,500 depending on opening modifications required.
