Demolition started on the water-damaged area and the contractor stopped. They think they found asbestos — in the popcorn ceiling, in the floor tiles, in pipe insulation, or in the drywall joint compound. Now everyone is standing around and you’re wondering what happens next.
Here is the sequence.
This is the correct call and your contractor is right to stop. Asbestos-containing materials (ACM) that are intact and undisturbed are generally not an immediate hazard. Asbestos-containing materials that are being cut, broken, or disturbed during demolition release fibers into the air — and that’s when exposure risk is created.
Don’t try to assess it yourself. Don’t take samples without proper equipment. Don’t disturb the material further. Stop work in the affected area and wait for the next step.
Not everything that looks like it might contain asbestos does. Popcorn ceilings installed after 1978 were generally not made with asbestos. Floor tiles from the 1960s very often were. Pipe insulation from the 1950s–1970s frequently was. Drywall joint compound used before 1977 commonly contained chrysotile asbestos.
The only way to know is to test. A certified industrial hygienist or asbestos inspector takes a small sample of the suspect material and sends it to an accredited laboratory. Turnaround is typically 24–72 hours for standard testing, same-day for rush.
In Texas, asbestos testing and abatement are regulated by the Texas Department of State Health Services (TDSHS). Inspectors who take samples for regulatory purposes must be TDSHS-licensed. Make sure whoever does the testing holds the appropriate Texas license.
Asbestos abatement — the removal of ACM — must be performed by a licensed asbestos abatement contractor in Texas. This is not optional and not a gray area. Performing your own abatement or hiring an unlicensed contractor to remove confirmed asbestos-containing material is illegal and creates significant liability.
The abatement process involves full containment of the work area, negative air pressure with HEPA filtration (similar to mold remediation containment), licensed abatement workers in full protective equipment, and disposal of ACM as regulated waste at a facility permitted to accept it. After abatement, clearance air monitoring confirms the area is below regulatory fiber counts before the containment is removed.
This is where it gets complicated. Homeowners insurance covers sudden and accidental water damage. Asbestos abatement costs are a separate category.
Many Texas homeowners policies have a specific asbestos exclusion — meaning the cost of testing and abatement is not covered even when the asbestos was discovered as a direct result of a covered water event. Some policies have a limited allowance — $5,000 to $15,000 — for pollutant or contaminant removal. Check your policy declarations and call your insurer directly to ask.
The water damage itself — the drying, the demolition of non-ACM materials, and reconstruction after abatement — remains a covered loss. Abatement is often the gap between what insurance covers and what the total project costs.
Houston’s housing stock includes a significant number of homes built between 1940 and 1980 — particularly in Midtown, Montrose, the Heights, Memorial, and Bellaire — when asbestos use in building materials was standard. Homes in these neighborhoods have a higher probability of containing ACM in floor tiles, pipe insulation, roof shingles, and ceiling texture than newer construction.
If your home was built before 1980 and you’re doing any renovation or restoration work that involves breaking into original materials, an asbestos pre-inspection before demolition starts is worth the $300–$500 cost. It’s significantly less expensive than discovering it mid-project.
Stop work. Test before disturbing anything further. If confirmed, hire a TDSHS-licensed abatement contractor. File the water damage claim regardless — the water damage itself is likely covered. The abatement cost may or may not be covered depending on your specific policy’s pollution exclusion language.
If you need help coordinating between water damage restoration and asbestos abatement — understanding what sequence makes sense, what needs to be documented, and how to keep the insurance claim on track — call 247 Restoration Specialists. We’ve worked on Houston homes where asbestos discovery complicated restoration, and we know how to sequence the work properly.
Asbestos testing in Houston typically costs $250–$600 for a standard inspection with laboratory analysis, depending on the number of samples taken and the turnaround time requested. Rush same-day results cost more. A full pre-renovation inspection of an older home — testing all suspect materials before any demolition — may cost $500–$1,200 depending on home size and number of material types.
In a contained area that is properly sealed from the living space, occupying unaffected portions of the home is sometimes possible. However, most abatement contractors and industrial hygienists recommend vacating the home during abatement because of the difficulty of maintaining perfect containment and the severity of potential asbestos fiber exposure. Discuss this directly with the licensed abatement contractor conducting the work.
Asbestos that has been professionally abated and documented does not typically reduce resale value — buyers can see that the issue was identified, tested, and properly remediated. Undisclosed, unabated asbestos discovered during a buyer’s inspection is a much larger problem for the transaction. In Texas, sellers have disclosure obligations regarding known material defects including known presence of asbestos.
