Renovating your Home
Asbestos Survey
If you qualify as an owner-occupied, single-family residence and you are doing the repair or remodeling project yourself, it is recommended, though not required, that you hire an AHERA Building Inspector to conduct a survey of the area to identify potential asbestos-containing materials. If the renovation project is being performed by someone other than you - the owner-occupant, then it is required that an AHERA-certified Building Inspector conduct the asbestos survey, along with other project requirements.
Below is a partial list of the types of materials that may contain asbestos. This list does not include every product that may contain asbestos. If these materials will be damaged or disturbed during a home renovation project, it’s best to have samples of them tested for the presence of asbestos. See the list of asbestos service providers, including accredited laboratories in the area that do testing.

If Asbestos is Found
If asbestos is found, don't panic. There are options.
1. Leave it alone. Asbestos is only a problem if fibers are released into the air. This can happen when asbestos-containing materials are damaged or disturbed. The best option may be to leave it alone. For example, rather than removing sheet vinyl flooring with asbestos backing, it may be possible to lay the new sheet vinyl on top of the old. If asbestos-containing material is damaged or may be damaged or disturbed during the remodel or repair project, then it should be repaired and encapsulated, or removed properly.
2. Repair and encapsulate. Sometimes asbestos-containing materials can be repaired and encapsulated rather than removed. A few inches of torn, loose or frayed asbestos tape on heating ducts may be sealed with paint or duct tape. Damaged hot water pipe insulation may be covered with a special fabric available at safety equipment stores. There are penetrating encapsulants that seep into asbestos-containing materials and bond with asbestos fibers and there are bridging encapsulants such as paint, which coat asbestos-containing materials with a more durable surface. Encapsulation may seem like an attractive option, just be aware that it could make future removal more difficult. In cases of extensive asbestos disturbance, removal may be the more appropriate option.
3. Remove it. There are two options for removal, each with distinct requirements.
- Hire a state-certified asbestos abatement contractor. This is a requirement for all demolition work and projects not being done by the resident homeowner. Hiring a company with trained, experienced certified asbestos abatement workers to do the removal may be your best option. If you hire a company to do the removal, notification must be made to Spokane Clean Air prior to removal. Notification and Fee information.
- Do it yourself. There are some projects than can be done safely if prescribed work procedures are followed. Some projects are very hazardous and should be performed by certified abatement contractors. Below are links to three guidebooks for common "do-it-yourself" asbestos removal projects. The guidebooks provide similar procedural steps as well as legal requirements for the proper removal, labeling and disposal of the asbestos-containing material.
