Percolation Tests FAQs, answered by experts

Older textures may contain asbestos, requiring careful handling and professional inspection before work begins to ensure safety compliance.

Federal law doesn’t require homeowners to disclose the presence of asbestos in their home, but some states and local municipalities may require it. That is why it’s important to test an older home for asbestos and other health hazards before moving forward with a sale.

Asbestos can be found in many building materials, especially if the materials were installed more than 20 years ago. Asbestos-containing materials (ACM) can include:

  • Acoustic ceiling tiles

  • Furnace insulation

  • Home appliances

  • Fire-retardant clothing

  • Cement pipe

  • Pipe insulation

  • Wall and ceiling insulation

  • Vehicle brake pads

  • Vinyl flooring

  • Sprayed acoustic ceilings

  • Stove insulation

  • Patching compounds

  • Textured paints

  • Roofing shingles

  • Siding

Many homeowners may never have to test their homes for asbestos. Asbestos particles are only dangerous if they become airborne. If you plan to do construction or notice damage to piping, siding, or drywall, you should hire a specialist to test for asbestos. 

If you plan to remodel your home or have any concerns, you should have your home tested for asbestos just to be safe.

Epoxying over asbestos tiles is generally considered a safe option when done correctly. Epoxy acts as a sealant, encapsulating the asbestos tiles and preventing the release of asbestos fibers into the air. The key is ensuring that the asbestos tiles are in good condition, firmly adhered to the substrate, and not damaged or deteriorating. This method is only appropriate for tiles that are undamaged and securely in place. If the asbestos tiles are already loose, damaged, or deteriorating, encapsulating them with epoxy may not be a sufficient solution, as it might not address the potential for ongoing asbestos exposure.
