Vinyl floor tile from the 1950s through the 1980s is the most common asbestos-containing flooring in residential and light commercial work. The 9×9 inch tile is diagnostic of that era — though lab confirmation is still required, since color and dimension alone are not proof. Sheet vinyl from the same era often used asbestos paper as backing, which is even more friable when disturbed.
What most homeowners miss: the tile itself is usually non-friable, and the mastic — the black adhesive bedded under the tile — is the dominant fiber source when sanded, ground, or scraped during removal. Pulling tiles up cleanly is often less risky than sanding them in place.
We test both layers, plan removal accordingly, and keep the work wet, contained, and HEPA-filtered start to finish. Disposal goes out manifested, and the floor is cleared before any new finish is installed.
Durham combines historic-district housing with mid-century ranch neighborhoods and a substantial older commercial inventory. All three of those building eras commonly contain asbestos materials in the places renovations want to touch.
