Code-Compliant Egress Installation
Egress Windows — Required for Legal Basement Bedrooms
If you want to use your basement as a legal bedroom on Long Island, you need egress windows. NYS Building Code requires egress windows in every sleeping room — including basement bedrooms — to provide an emergency escape route. Without egress, your basement bedroom is technically illegal and won't be counted in your home's bedroom count by appraisers.
We've installed egress windows in hundreds of Long Island basements, from straightforward slab cuts to complex multi-window projects in older homes with thick concrete block walls. We handle every aspect: cutting the foundation wall opening, excavating the window well, installing the waterproofed well liner, and setting the egress-rated window unit.

Egress Window FAQs — Long Island
Both Nassau and Suffolk Counties follow NYS Building Code requirements for egress windows: minimum 5.7 sq ft of net clear opening, minimum 24 inches clear height, minimum 20 inches clear width, and maximum 44 inches sill height above floor. Bedrooms require egress windows for legal occupancy — critical if you're converting a basement to a bedroom.
The cost varies based on foundation wall thickness, soil conditions, excavation depth, and number of windows. Multiple windows on the same visit are more efficient. We give free on-site estimates — call us to schedule and we'll assess your specific situation before giving you a number.
Yes. Egress window installation requires a building permit in both Nassau and Suffolk Counties. The permit covers the structural opening in the foundation wall, electrical if needed, and the waterproofed window well. We pull all permits and coordinate building department inspections.
A single egress window installation typically takes 1–3 days including excavation, structural work, window well installation, and backfill. Two windows on the same project add 1–2 days. Building department inspection timing adds additional days to the overall schedule. Most projects are complete within 1–2 weeks including permit approval.
