Watch Out for Asbestos Tape on Ductwork: What You Need to Know

November 20, 2023 · Planet Duct

Hi, readers! Brandon Kirk, owner of Planet Duct, here. Today, I want to draw your attention to a critical but often overlooked issue in older homes and buildings in Colorado Springs — the presence of asbestos tape in air ducts. I recently had an eye-opening (but not uncommon) experience while working in a crawl space, which I believe is vital for everyone to be aware of, especially if you live or work in a building constructed in the mid-20th century.

Identifying the Hazard in Your Air Ducts

In my line of work with Planet Duct, I frequently encounter air ducts made in the late 40s or early 50s. A common feature of these old ducts is a distinctive type of tape used for sealing. Unlike standard duct or metal tape, this particular tape is white, often found in varying conditions. In some cases, it may appear water-damaged or deteriorated. 

The Asbestos Threat

While I'm not a certified asbestos professional, my experience suggests that this white tape should be treated with caution. It's what we refer to as a suspected asbestos-containing material. Asbestos, as many of you might know, was a popular insulating material used extensively until its health risks became widely acknowledged. 

Here’s the various ways that asbestos can become harmful:

Why It Matters

The presence of suspected asbestos tape on air ducts is a significant concern. When disturbed, asbestos can release fibers into the air, posing severe health risks, including respiratory issues and even cancer. Therefore, if you encounter this type of tape, it's crucial not to attempt cleaning the ducts yourself.

Given the threat of asbestos tape in your vents, it’s vital that you get it removed safely. We highly recommend calling Rex Environmental, a well-regarded asbestos testing and remediation company in Colorado. 

Identifying Asbestos Duct Tape

Given the threat of asbestos tape in your vents, you want to be sure if your air ducts have it or not. Here’s what to look out for and be aware of when identifying asbestos duct tape:

Immediate Steps to Take

Avoid Disturbance: Do not engage in any activity that could agitate the tape, such as cleaning, abrasion, or causing vibration.

Professional Testing: Contact a professional environmental company for asbestos testing. I tell all my clients that Rex Environmental is a reliable choice for such services.

Seek Expert Advice: Depending on the test results, connect with an asbestos abatement contractor. They can safely handle the situation if asbestos is present.

A Word of Caution

Remember, even if the tape seems stable, any disturbance could release harmful fibers. The rule of thumb is if in doubt, don't touch it. Get it tested first.
