Can Asbestos Siding Be Safely Removed From My Home?

If you own an older home, there's a meaningful chance the siding on its exterior contains asbestos. For decades, asbestos cement siding — often called "transite" or sold under brand names like Certain-Teed, Eternit, and Superflex — was one of the most popular exterior cladding materials in America. It was affordable, durable, fire-resistant, and seemingly ideal. What wasn't understood at the time was the serious health hazard lurking inside those panels.

Today, homeowners facing renovation, re-siding projects, or the sale of an older home frequently ask the same question: Can asbestos siding be safely removed from my home? The short answer is yes — but, when done correctly, by licensed professionals, following strict regulatory protocols. Here's what you need to know.

What Is Asbestos Siding and Why Is It Dangerous?

Asbestos siding is an exterior building material composed of Portland cement reinforced with asbestos fibers — typically chrysotile (white asbestos). These fibers were prized for their tensile strength and heat resistance. Manufacturers wove them into cement panels that could withstand decades of weather exposure without warping, rotting, or burning.

The danger isn't the asbestos itself sitting undisturbed in the panels. The danger is what happens when those panels are disturbed. When asbestos-containing materials are cut, drilled, broken, sanded, or improperly handled, they release microscopic asbestos fibers into the air. Those fibers, once inhaled, can embed permanently in lung tissue and can cause:

• Mesothelioma — a rare and aggressive cancer of the lining of the lungs, heart, or abdomen
• Asbestosis — progressive scarring of lung tissue leading to severe respiratory impairment
• Lung cancer — particularly in individuals with a history of smoking
• Pleural plaques — thickening and calcification of the lining surrounding the lungs

These diseases typically don't appear for 20 to 50 years after exposure, which means exposure during a weekend DIY project today can carry consequences that won't surface until decades from now. This delayed onset is precisely why asbestos remains one of the most dangerous occupational and residential hazards in existence.

Friable vs. Non-Friable Asbestos Siding: A Critical Distinction

Before any asbestos siding removal project can be scoped properly, it's essential to understand whether the material is friable or non-friable.

Non-friable asbestos is material that, when dry, cannot be crumbled, pulverized, or reduced to powder by hand pressure. Asbestos cement siding in good condition is typically non-friable — the fibers are bound within the hardened cement matrix. In this state, the siding poses a lower immediate risk, though it is by no means safe to handle carelessly.

Friable asbestos is material that can be easily crumbled by hand, releasing fibers into the air. Asbestos siding that has weathered severely, been previously damaged, or has begun to deteriorate can become friable. Friable materials present a significantly higher risk of fiber release and require even more stringent handling protocols.

Here's the critical point most homeowners miss: even non-friable asbestos siding becomes friable the moment you begin working on it. Cutting, nailing, drilling, or breaking panels during removal immediately liberates asbestos fibers. What was "safe" on the wall becomes dangerous the moment a saw blade or hammer makes contact.

Is Asbestos Siding Removal Required by Law?

This is one of the most common questions homeowners bring to us at Absolute Asbestos Services. The answer depends on your jurisdiction, the scope of work, and the condition of the material.

In many states and municipalities, disturbing asbestos-containing materials requires advance notification to state environmental or occupational health agencies — often 10 business days before work begins. The EPA's National Emission Standards for Hazardous Air Pollutants (NESHAP) regulations govern asbestos work on larger commercial demolitions, but state regulations frequently apply stricter rules to residential projects as well.

In Washington State, the Department of Labor & Industries (L&I) and the Department of Ecology regulate asbestos abatement. Homeowners performing work on their own single-family residence may be permitted to handle certain asbestos-containing materials themselves under specific conditions — but professional removal is almost always the legally safer and practically wiser choice.

Before any work begins, you should:

1. Have the suspect material tested by an accredited asbestos inspector
2. Determine applicable local, state, and federal notification requirements
3. Engage a licensed asbestos abatement contractor to perform or oversee removal
4. Ensure proper disposal at an approved facility — asbestos waste cannot be placed in standard trash

The penalties for improper asbestos disposal or failure to follow notification requirements can be severe, including substantial fines and liability for any third-party health impacts

What Does Professional Asbestos Siding Removal Actually Look Like?

When you engage a licensed asbestos abatement contractor like Absolute Asbestos Services, the removal process is methodical, documented, and rigorous. Here's a general overview of what the professional process entails:

Pre-Project Inspection and Testing

A certified asbestos inspector collects bulk samples of the suspect material and submits them to an accredited laboratory for polarized light microscopy (PLM) analysis. This confirms whether asbestos is present and at what concentration. No responsible contractor proceeds with removal work without this step documented.

Work Area Preparation and Containment

The work zone is carefully prepared to prevent fiber migration. This includes:

• Wetting the siding panels with amended water (water with a surfactant added) to suppress fiber release during removal
• Establishing negative air pressure enclosures where required
• Sealing off adjacent HVAC systems, windows, and doorways
• Posting warning signage in accordance with OSHA and EPA requirements

Personal Protective Equipment

Workers performing asbestos siding removal must wear at minimum:

• A half-face or full-face respirator equipped with HEPA-rated P100 filters (or a supplied-air respirator for higher-risk scenarios)
• Disposable Tyvek coveralls that are bagged and discarded after each work session
• Gloves and boot covers

Careful, Methodical Removal

Panels are removed as whole units whenever possible to minimize breakage and fiber release. They are never dry-cut, dry-scraped, or mechanically abraded. Wet methods are used consistently throughout.

Proper Disposal

Asbestos waste is kept wet and double-bagged in 6-mil polyethylene bags or wrapped in sheeting, clearly labeled with EPA-required hazard warnings, and transported to a licensed asbestos disposal facility. This is a regulated activity — documentation of disposal is required and retained.

Post-Abatement Clearance

A qualified air monitoring professional conducts clearance air testing after the work area is cleaned, verifying that airborne asbestos fiber concentrations meet or exceed clearance standards before the area is reopened.

Can You Leave Asbestos Siding in Place?

In some situations, the most prudent choice isn't removal — it's encapsulation or simply leaving the material undisturbed. If asbestos siding is in good condition, firmly intact, and not scheduled for renovation or demolition, it may legally and practically be left in place.

At Absolute Asbestos Services, we help homeowners evaluate all viable paths based on the condition of the material, the scope of planned renovations, long-term ownership plans, and budget considerations. There is no universal right answer; there is only the right answer for your specific property.

In some rare cases, homeowners insurance companies will conduct their own risk assessment related to asbestos and may decline to extend coverage to a home that has asbestos siding or other asbestos containing materials. Some home lenders and specific home lending programs will also decline unless the asbestos containing materials are removed.

How Much Does Asbestos Siding Removal Cost?

Asbestos siding removal costs vary based on several factors:

• Square footage of siding to be removed
• Condition of the material (intact vs. deteriorated)
• Accessibility (single-story vs. multi-story, landscaping, etc.)
• Disposal fees
• Required air monitoring and clearance testing

The best approach to pricing is getting a professional like Absolute Asbestos Services out to do an assessment, discuss the options and project goals and prepare a bid for the work. Be wary of contractors who are willing to bid a project over the phone without these details and a first person perspective from being at the property. They may have a low bid but it is likely to have many disclaimers that can lead to "unforeseen" costs and a much higher final invoice at the end of the project.

Another detail that can come into play in a situation where asbestos siding is on a home is lead based paint. During the era when this siding was being used, exterior paints with lead in them was common. Be sure your contractor is also testing for this possibility as it may change the scope of work and overall project cost.
