Common asbestos floor tile types
in Southeast Michigan
If your home was built before 1985, these are the materials most likely to test positive. Only PLM lab analysis confirms.
Almost universally positive in pre-1985 installs. Speckled/marbled pattern. 1940s–1970s. 15–25% asbestos content typical.
Transition era 1960s–mid-1980s. Lab analysis required — identical appearance to asbestos-free versions. 5–15% typical.
Dark brown/black adhesive beneath the tile. Often asbestos-containing even when tiles are not. Must be addressed as part of abatement.
Pre-1985 'linoleum' — asbestos often in the paper/felt backing, not the surface layer. Backing must be sampled separately.
Intact floor tile is generally not an active hazard. Disturbed asbestos tile is. The fastest way to turn a $2,000 abatement into a $15,000 contamination response is to start tearing things up before you know what you have.
Removal vs. encapsulation —
which is right for you?
About 25% of floor tile inquiries we receive are better served by encapsulation, not removal. We'll tell you which is the right answer for your situation.
- Renovation requires subfloor access
- Tile is broken, loose, or deteriorating
- Installing LVP, hardwood, or products needing flat substrate
- Pre-sale — documented removal is cleaner disclosure
- Tiles already partially removed or disturbed
- Tile is fully intact, undamaged, and well-adhered
- No subfloor access needed for renovation
- Installing carpet or LVP over flat, intact tile
- No immediate plans to sell
- Faster and cheaper: typically saves $1,500–$4,000 vs. removal
