Code-Compliant Egress Installation

Egress Windows — Required for Legal Basement Bedrooms

Egress window installation in Long Island basement with window well

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.
