How To Get Rid Of Asbestos Siding: Professional Removal And Safety Protocols
Removing asbestos-cement siding requires strict adherence to localized containment procedures, specialized personal protective equipment (PPE), and regulatory compliance with federal and state environmental mandates. Because asbestos fibers are carcinogenic when inhaled, homeowners must prioritize professional abatement or utilize rigorous wetting, sealing, and hazardous waste disposal methods to prevent toxic airborne release.
Hazard Assessment and Regulatory Compliance Planning
Asbestos-cement siding, commonly installed between the 1920s and the 1980s, typically consists of 10% to 15% chrysotile asbestos fibers bound in a Portland cement matrix. While the material is non-friable when intact, any disturbance involving cutting, sanding, scraping, or breaking releases hazardous microscopic fibers. Before initiating any removal, you must verify your local jurisdiction's laws. The United States Environmental Protection Agency (EPA) under the National Emission Standards for Hazardous Air Pollutants (NESHAP) regulates the removal of asbestos-containing materials (ACM). In many regions, homeowners are permitted to remove their own residential siding, but they remain legally liable for environmental contamination and must follow strict disposal protocols for hazardous waste facilities.
Essential Removal Checklist
- PPE Requirements: You must use a NIOSH-approved P100 half-face or full-face respirator. Do not use standard N95 or surgical masks, as they cannot filter fine asbestos fibers. Wear disposable, hooded, impermeable Tyvek coveralls, nitrile gloves, and shoe covers.
- Containment Gear: Stock heavy-duty 6-mil polyethylene sheeting, duct tape for sealing, a garden sprayer filled with an amended water solution (water mixed with a surfactant/detergent to penetrate the material), and high-efficiency particulate air (HEPA) vacuum cleaners.
- Documentation: Before starting, contact your local landfill or hazardous waste transfer station to confirm their specific acceptance criteria for ACM. Most facilities require specialized labeling and documentation confirming the waste was wetted and double-bagged.
- Environmental Scope: Expect a project duration of two to four days for an average-sized home. Budget significantly for hazardous waste disposal fees, which are calculated based on weight and vary drastically by municipality.
The Systematic Asbestos Siding Abatement Workflow
Step 1: Site Isolation and Containment
Clear the area surrounding the home of all loose debris. Lay down 6-mil polyethylene sheeting extending at least 10 feet from the base of the exterior walls. This plastic drop cloth must be secured to the siding using duct tape to catch any falling chips or dust. If the work is performed during windy conditions, seal the perimeter edges with wooden slats or heavy bricks to prevent the containment material from shifting.
Step 2: Moistening the Material
The primary defense against airborne asbestos is keeping the siding wet throughout the entire duration of the removal. Mix a surfactant with water in a pressurized sprayer; the surfactant breaks the surface tension of the water, allowing it to soak into the cement rather than beading on top. Thoroughly saturate the entire wall section you intend to work on. Re-wet the area periodically to ensure the siding remains damp. Never use power washers, as the high-pressure stream atomizes fibers into the air.
Step 3: Mechanical Disassembly
Use hand tools only to remove the siding. Locate the nails holding the siding panels in place. Using a pry bar, carefully lift the overlapping edge of the panel above the one you intend to remove. Use a nail puller or snips to cut the nails; do not attempt to hammer or snap the siding off, as this increases the likelihood of breakage. If a panel must be moved or adjusted, do so slowly and keep it wet. Avoid any action that involves sawing, drilling, or breaking the panels.
Step 4: Debris Management and Packaging
As you remove the panels, place them immediately into double-layered 6-mil polyethylene bags. Do not allow pieces to dry out on the ground. Once a bag is filled, press the air out slowly—taking care not to exhale air through the bag—and seal it with duct tape using the "gooseneck" method to ensure an airtight closure. Label each bag clearly with "Asbestos Waste" as per OSHA and EPA labeling standards.
Step 5: Final Decontamination
Once all siding is removed, use a HEPA-filtered vacuum to clean the poly sheeting and the immediate area of any dust. After vacuuming, carefully roll up the polyethylene sheeting, pulling the edges inward to trap any remaining residue, and place the contaminated plastic into a hazardous waste bag. Dispose of your PPE in the same hazardous waste stream. Thoroughly wash your skin and hair after leaving the containment area.

Field Troubleshooting: Addressing Procedural Failures
- Accidental Breakage: If a panel snaps during removal, immediately stop work. Spray the broken edges heavily with your amended water solution to bind the fibers. Carefully pick up all fragments, place them in a waste bag, and clean the surrounding area with a HEPA vacuum.
- Inadequate Disposal Facilities: If your local transfer station refuses the waste, do not leave it in an unsecured area. Contact a professional hazardous materials waste management company. You must obtain a formal waste manifest that tracks the asbestos from your home to a state-licensed disposal site.
- Neighbor Complaints: If neighbors express concern regarding visible dust, immediately cease operations. Cover the area with plastic sheeting and dampen the work zone thoroughly. Open communication is essential; provide proof of your containment setup and verify that you are following local nuisance and health ordinances.
Frequently Asked Questions
Can I paint over asbestos siding instead of removing it?
Yes, painting is often the safest and most cost-effective alternative to removal. Encapsulation via high-quality exterior acrylic paint prevents fibers from becoming airborne, provided the siding is in good condition and not crumbling.
Is it illegal to remove asbestos siding myself?
In many U.S. jurisdictions, federal law allows homeowners to remove asbestos from their own primary residence. However, strict state or municipal regulations may override this, and you are always held liable for environmental contamination if you do not follow proper disposal procedures.
How do I know if my siding definitely contains asbestos?
You cannot visually confirm the presence of asbestos. You must collect a small sample and send it to a NVLAP-accredited laboratory for Polarized Light Microscopy (PLM) testing. Wear a respirator while taking the sample and use a damp cloth to clean the area afterward.
What is the primary health risk of asbestos siding?
The primary risk is the inhalation of microscopic asbestos fibers, which can cause mesothelioma, asbestosis, or lung cancer. These diseases often have a latency period of 20 to 50 years, making immediate protection essential even if no symptoms are present.
