Asbestos siding was once a popular choice for its durability and fire resistance. However, as asbestos has been associated with health concerns, homeowners often seek to cover it with alternative siding materials. One common question is whether you can nail new siding over existing asbestos siding. In this article, we’ll provide a straightforward and concise answer.

Understanding Asbestos Siding

Asbestos siding, often referred to as "cement asbestos siding" or "transite siding," is made from a mixture of asbestos fibers and cement. While it was widely used in the past, concerns about asbestos exposure have led many homeowners to consider covering it with a safer siding option.

Can You Nail New Siding Over Asbestos Siding?

The answer is yes, you can nail new siding over existing asbestos siding. This approach is often preferred over removing asbestos siding, which can be a complex and costly process, requiring specialized disposal due to asbestos’s hazardous nature.

Here are the essential steps to follow:

1. Prepare the Asbestos Siding:
2. Inspect the asbestos siding for any damage or loose pieces. Repair or secure any loose sections to create a stable base for the new siding.

3. Install Furring Strips:
4. Install horizontal furring strips, typically made of wood or metal, over the asbestos siding. These strips create an even surface for nailing the new siding and allow for air circulation, which can prevent moisture-related issues.

5. Select the New Siding:
6. Choose the new siding material that suits your preferences and requirements. Common choices include vinyl, wood, or fiber cement siding.

7. Nail the New Siding:
8. Use appropriate nails for the selected siding material and nail the new siding to the furring strips. The type and length of nails will depend on the new siding’s requirements.

Safety Precautions:

• Wear appropriate safety gear, including a dust mask and gloves, when working near asbestos materials.
• Consider professional assistance for asbestos siding removal if it’s severely damaged, deteriorating, or poses a health risk.

In Conclusion

Nailing new siding over existing asbestos siding is a viable option to update the appearance and improve the insulation of your home. By following the steps mentioned and taking necessary safety precautions, you can safely and effectively cover asbestos siding with a more modern and safer siding material. Always consult local regulations and guidelines to ensure compliance with asbestos-related laws and regulations in your area.
