Basement Egress Window Installation in Germantown, MD: Planning, Code, and Cost

A basement egress window looks straightforward from the outside, but the real work starts once you factor in structure, drainage, code, and finishing details.

The practical payoff is hard to miss, since a proper egress opening can make a basement safer, brighter, and more valuable at the same time.
