Asbestos is magnesium silicate in the form of a fibrous mineral. It is versatile because it can withstand extreme heat and chemical actions. Siding shingles were made from asbestos as well as roofing, insulation, brake linings and fireproofing material. The material was banned in the 1980s as a known carcinogen. It can cause lung cancer, mesothelioma and other lung conditions. The material exists in many buildings including siding shingles used in residential buildings. The state of North Carolina requires testing and accreditation by asbestos abatement contractors. It also requires strict disposal at hazardous waste sites.
Things You'll Need
Permit application form DHHS-3768 from the NC Health Hazard Control Unit
Local permit for hazard material
Local building/demolition permit
Accredited asbestos removal contractor
A North Carolina-accredited asbestos inspector must inspect the property prior to any construction. He will determine the presence of asbestos and procedures for removal. Contact the North Carolina Health Hazard Control Unit at 1912 Mail Service Center Raleigh, NC 27699-1912, or call 919-707-5950 for notification and a permit. Asbestos siding removal over 160 square feet requires a permit.
After the inspection for asbestos siding, complete the application form DHHS-3768 and submit it to the North Carolina Health Hazard Control Unit. Submit the permit application no less than 10 days prior to construction. Permits are required in Buncombe, Forsyth and Mecklenburg counties in addition to the state.
Prepare a work order including the siding removal by an accredited asbestos contractor. A list of accredited asbestos contractors can be found on the North Carolina EPI website. List the installation of the new siding separate from the removal. Include capping of the soffit, fascia and windows. Get a price from at least three qualified contractors and a copy of their North Carolina accreditation for asbestos removal and proof of liability insurance.
The North Carolina Asbestos Hazard Management brochure states that the removal of asbestos siding will include wet removal so that fibers do not fill the air. Bag the material for dumping at an approved dump site. Conduct air testing to record any contamination of the work area.
It is wise for family members to avoid the work site area during construction. When the work is complete and you are satisfied with the cleanup and quality of work, contact the local authorities for an inspection.
Obtain a workmanship warranty from the contractor and warranties that accompany the material from the manufacture.
Writing a work order that will include the material number of the siding that you want will speed things up and cause all contractors to bid on the exact material.
Do not pay the contractor up front or release final payment until you are satisfied.
It is dangerous and illegal for a noncertified contractor to remove asbestos siding. Do not attempt to remove asbestos siding yourself.
Do not allow children or pets to play around the work area. Asbestos fibers get into the air that can attach to clothing, causing contamination.
