A recent story from Australia has grabbed headlines worldwide. A grandmother lost her family home of 50 years after discovering dangerous asbestos throughout the property. The cost of removal was so high that the house became worthless. While this happened overseas, the warning applies directly to American homeowners — especially those living in homes built before 1980.
Asbestos was once called a "miracle material." Builders loved it because it resisted fire and heat. They used it in insulation, floor tiles, ceiling tiles, roof shingles, siding, and even pipe wrapping. The problem? Breathing in asbestos fibers can cause serious lung disease and cancer. The dangers became clear decades ago, but millions of older American homes still contain this hidden hazard.
The EPA estimates that asbestos may be present in as many as 30 million homes and buildings across the United States. Most of these structures were built before 1980, when asbestos use was most common. If your home falls into this age range, there is a real chance asbestos is hiding somewhere inside your walls, floors, or ceilings.

Asbestos does not announce itself. You cannot see it or smell it. It often looks like ordinary building material. Here are the most common places it hides in pre-1980 homes:
- Insulation — especially around pipes, boilers, and ducts
- Floor tiles — vinyl and linoleum tiles from the 1950s through 1970s
- Ceiling tiles — including popcorn or textured ceilings
- Roof shingles and siding — cement-asbestos products were very popular
- Joint compound and plaster — used to seal walls and ceilings
- Vermiculite insulation — often found in attics
The danger comes when these materials are disturbed. Cutting, drilling, sanding, or tearing out old materials can release tiny asbestos fibers into the air. Once airborne, these fibers can be breathed in and may cause health problems years later.
Why This Matters Before Renovation
Many homeowners discover asbestos the hard way — in the middle of a renovation project. They tear out old flooring or knock down a wall, only to learn later that they may have exposed themselves and their families to asbestos dust.
The Australian grandmother's story is a clear warning. She lived in her home for half a century without knowing the danger. When experts finally inspected, the asbestos problem was so widespread that the home could not be saved. While not every case is this extreme, the lesson is simple: test before you renovate.
Professional asbestos inspections can cost hundreds of dollars. Many homeowners skip this step because of the expense. But there is a more affordable option. DIY asbestos test kits let you collect a small sample of suspicious material and mail it to a certified lab. You get clear results without paying for a full inspection.
What to Do If You Own a Pre-1980 Home
First, do not panic. Asbestos that is in good condition and left alone is generally not dangerous. The fibers only become a risk when the material is damaged or disturbed.
Second, identify any materials that look suspicious. Pay close attention to insulation, old floor tiles, ceiling tiles, and pipe wrapping. If you plan to renovate, drill, or make repairs in these areas, testing first is the smart move.
Third, never try to remove asbestos yourself. If your test comes back positive, hire a licensed asbestos abatement professional. Improper removal can make the problem much worse by spreading fibers throughout your home.
Frequently Asked Questions
How do I know if my home has asbestos?
You cannot identify asbestos just by looking at it. The only way to know for sure is to have a sample tested by a certified laboratory. Homes built before 1980 are most likely to contain asbestos in insulation, floor tiles, ceiling materials, and siding.
Is it safe to live in a house with asbestos?
Yes, if the asbestos-containing materials are in good condition and not disturbed. The danger comes when materials are damaged, crumbling, or disturbed during renovation. That is when fibers can become airborne and pose a health risk.
Should I test for asbestos before remodeling?
Absolutely. Any renovation work that involves cutting, drilling, or removing old building materials can disturb asbestos. Testing suspicious materials before you start protects you, your family, and your contractors from exposure.
If you own a home built before 1980 and have concerns about asbestos, testing is the first step toward peace of mind. The MycoTest DIY Asbestos Test makes it easy to collect a sample and get certified lab results — no inspector appointment needed, and results arrive in days.
