This subject comes up on every home when we look at new windows.  It is widely known about the need for an escape window for a basement bedroom.  Over the years building codes have changed and updated.  The Egress requirement has now moved to the main floor and upstairs for bedrooms.  How each building department handles this situation can differ greatly.  Knowing this requirement and willing to verify this requirement for where you live is important for you to understand and decide when looking at new windows.  There are specific requirements for width, height, and useable opening square feet.  there is also a requirement for height above the floor.  Leading Edge Renovation is fully versed in these requirements and can explain them to you.  We will also verify with your building department as they can change how they enforce this project.  Any company not discussing this with you is not fully informing you of the situation.
