  • Pipe insulation

  • Wall and ceiling insulation

  • Vehicle brake pads

  • Vinyl flooring

  • Sprayed acoustic ceilings

  • Stove insulation

  • Patching compounds

  • Textured paints

  • Roofing shingles

If air samples are required, then the pro will set up a testing device and return to collect it. In both cases, the sample is sent to a lab and results are confirmed or denied usually within one to two days.
