asbestos concern in duplex remodel

[Tony Karns]

Hey guys, I am about to begin remodeling a duplex. It's a major project and we are taking down walls/moving air vents and pulling up the flooring. Unfortunately I did not think about this before hand, but it has been brought to my attention that asbestos could be a concern since the building was build in 1968. 

Questions : Should I call an asbestos testing abatement company?

  If yes any recommendation in the Dallas Area?

  If No How should I proceed?
