Should I test old flooring for asbestos if I'm just covering it up?
Testing may not be strictly necessary if you plan to completely avoid sanding or major disturbances and simply cover the material. However, if a water leak or future repairs force you to eventually pull up the flooring, the disturbance becomes unavoidable. Deciding whether to test depends on whether you can safely encapsulate it long-term or if you will eventually have to tear it out.
