Concrete Egress Windows and Doors
Concrete wall cutting allows access to subgrade living spaces.

National building codes require the installation of egress windows or doors when converting basement spaces into living areas. Egress windows provide an alternative exit from the basement.  We can work with your choice of contractor or complete the installation for you.

Things to consider when installing an egress opening:

  • Is the proposed location structurally safe?
  • Who is going to protect the interior from dust and debris during the cutting process?
  • Who is going to remove concrete?
  • Who is disposing of the concrete?
