Fishing a new cable or wire behind walls can be quite a process after a home is built.  It can be expensive too, especially if drywall repairs and fresh paint are involved.

We generally install several lengths of conduit in various locations during the construction of a new home.  Conduits can be buried in the ground, behind the drywall, or in the attic.

By installing conduit, you are free to change or upgrade wiring long after your home is done.
