How Do Pros Handle Hazardous Building Materials?
Last updated October 31, 2026
The short answer
Identifying Hazards First
Before any water damage work begins, the pros check for hazardous materials. Older homes often contain asbestos in drywall, ceiling tiles, or pipe insulation. Lead paint may be under layers of newer paint on walls and window frames. Mold can grow behind wet drywall within days, creating a health risk.
The pros use visual checks and sometimes send samples to a lab for testing. If they find asbestos or lead, they stop the normal cleanup and bring in a specialized abatement professional. You should not touch or disturb these materials, as that can release dangerous fibers or dust into the air.

- Lead paint on walls and trim
- Mold growth on wet surfaces
- Contaminated water from sewage or flood
- Old electrical wiring that is wet
Protecting the Work Area
Once hazards are known, the pros set up containment. They seal off the room with plastic sheeting and use negative air pressure to keep dust from spreading. They wear respirators, gloves, and protective suits to avoid contact with harmful substances.
Containment also protects the rest of your home. The pros may remove wet carpet, drywall, and insulation in sealed bags. They do not let anyone without protective gear enter the area until cleanup is complete. This keeps everyone safe and prevents cross-contamination.
Safe Removal and Disposal
Hazardous materials require careful removal. Asbestos and lead are regulated by federal and state rules, so the pros follow strict procedures for taking them out. They wet materials to reduce dust, and they place everything in labeled, leak-proof containers.
Disposal also follows the law. The pros take hazardous waste to approved facilities, not the regular trash. You should ask for a description of how the waste will be handled, but you do not need to oversee the process. The cost for hazardous material removal depends on the type and amount found.
Cleaning Up After Removal
After the hazardous materials are gone, the pros clean the entire area. They wipe down surfaces with special solutions and vacuum with HEPA filters to catch any remaining dust. This step is important because even tiny amounts of asbestos or lead can be harmful over time.
The pros also check for moisture and mold. They dry out the structure to prevent new mold growth. If mold is extensive, a mold professional may be needed. The goal is to leave the space safe for you and your family to be in again.
When to Call the Pros
You should not attempt to remove hazardous materials yourself. If you suspect asbestos, lead, or mold after water damage, leave the area and contact a local water damage pro. They have the training and equipment to handle these risks properly.
Act quickly to prevent further damage, but do not rush into a contaminated space. If you feel unwell, see a doctor. For homes in Mesa, having a plan for water damage can help, but the pros will manage the hazardous side of the job.

Can I stay in my home during hazardous material cleanup?
Usually not. The pros seal off the work area and may need you to leave for a short time, especially if asbestos or lead is present. Follow their advice for your safety. If you feel unwell, see a doctor.
Does my insurance cover hazardous material removal?
Policies vary, and your insurer decides what is covered. Some policies include asbestos or lead abatement after water damage, but others do not. Check your policy or ask your insurance company directly.
How do I know if my home has asbestos or lead?
Homes built before 1980 are more likely to have these materials. The pros can test samples to confirm. Do not take samples yourself, as that can release fibers. Let the pros handle testing and identification.
