A lot of homeowners don’t think about asbestos until they start pulling something apart.
It usually starts with a renovation. Maybe you are updating a kitchen. Maybe you are replacing old flooring. You pull up one layer and there is something underneath you didn’t expect.
Small square tiles. Often 9 by 9. Sometimes a little worn. Sometimes still in decent shape.
Then someone says, “That might be asbestos.”
If you are in Medford or nearby areas like Somerville, Cambridge, or Malden, this situation comes up all the time. A lot of homes in this region were built or renovated during decades when asbestos was commonly used in flooring materials.
So the question becomes pretty simple.
Are these tiles asbestos, and what should you do next?
Why 9×9 Tile Gets Flagged So Often
There is a reason inspectors and contractors react quickly when they see 9×9 tile.
For many years, vinyl floor tiles were manufactured with asbestos fibers to improve durability and heat resistance. Those tiles were widely used in homes, schools, and commercial buildings.
The 9×9 size is often associated with older installations, especially from the mid 1900s. That does not mean every 9×9 tile contains asbestos, but it is enough of a pattern that professionals take it seriously.
Even larger tiles, adhesives, and backing materials can sometimes contain asbestos as well.
The challenge is that visually, asbestos tile looks almost identical to non-asbestos tile.
There is no reliable way to confirm it just by looking.
What About the Black Glue Underneath?
A lot of homeowners notice the adhesive before anything else.
That black, tar-like glue under old tiles is often called mastic. In older homes, it can contain asbestos too.
So even if the tile itself is not the issue, the material holding it in place might be.
That is why proper testing usually includes both the tile and the adhesive underneath.
What Should You Do If You Find It
The instinct for many homeowners is to keep going. The project has already started. The flooring is halfway removed. It feels easier to just finish the job.
That is where problems begin.
If you suspect tile may contain asbestos, the safest move is to pause and get it tested before continuing.
This is especially important if the tile is being broken, scraped, or removed in pieces. That is when fibers can become airborne.
A quick inspection and lab test can give you a clear answer within a few days.
From there, you can decide how to move forward.
A Situation That Happens All the Time
A homeowner in Medford starts replacing flooring in a basement.
The top layer comes off easily. Underneath is older tile. Some of it is already cracked. A few pieces break during removal.
At that point, the question comes up.
Do we stop or keep going?
Testing confirms whether asbestos is present. If it is, the next steps are handled safely instead of guessing in the middle of demolition.
Catching it early usually keeps the situation under control.
If the Tile Contains Asbestos, What Happens Next
This is where people expect things to get complicated.
In reality, there are a few common paths depending on the condition of the material.
If the tile is intact and not being disturbed, it can sometimes be left in place and covered.
If removal is needed, licensed professionals handle it under controlled conditions.
In some cases, homeowners choose to encapsulate rather than remove, especially in areas that will not be heavily used.
Worker safety standards are overseen by the Occupational Safety and Health Administration, while environmental rules in Massachusetts are managed by the Massachusetts Department of Environmental Protection and guidance from the U.S. Environmental Protection Agency.
The key is that there is a clear process. It just needs to be handled the right way.
Is It Dangerous If It Has Been There for Years
This is one of the most common questions.
Many homes have had these materials in place for decades without issue. The concern is not usually the presence of the material. It is the disturbance of it.
Cutting, sanding, scraping, or breaking tile can release fibers into the air.
That is why renovation is the moment when asbestos becomes relevant.
What About Covering the Tile Instead of Removing It
Some homeowners consider installing new flooring directly over old tile.
In certain cases, that can be an option. It depends on the condition of the existing floor and the type of renovation being done.
This is something that should be evaluated carefully. Covering intact material can sometimes avoid unnecessary disturbance, but it is not the right choice in every situation.
Questions That Come Up Right Away
How can I tell if my tile contains asbestos
You cannot confirm it visually. Testing is the only reliable way.
Should I stop my renovation immediately
If materials are being disturbed and you are unsure, pausing for testing is the safer move.
Is removing it always required
Not always. It depends on condition and future plans.
Does this delay my project
Testing usually adds a short window. Finding asbestos mid demolition can cause longer delays.
Where This Fits Into Your Bigger Renovation Plan
If you are renovating an older home in the Greater Boston area, this is just one of those checkpoints that helps everything go smoother.

Final Thoughts
Finding 9×9 tile or old vinyl flooring during a renovation can feel like a setback at first.
In reality, it is just information.
What matters is what you do next.
Testing early gives you a clear answer and helps you avoid bigger problems later in the project. It keeps your timeline predictable and your decisions informed.
If you are working on a home in Medford or anywhere in the Greater Boston area and come across older flooring materials, having them evaluated before continuing is usually the smartest move.
