Most of us understand what it takes to stay healthy.
We try to eat nutritious foods.
We exercise.
We go to annual checkups.
We pay attention when something doesn’t feel right.
We know that our health requires ongoing care.
But how often do we think about our homes the same way?
Many of us assume that if a house looks clean, smells fine, and nothing appears to be broken, it must be healthy.
According to building biologist Alex Stadtner, that’s one of the biggest misconceptions homeowners have.
In this week’s episode of Never Been Sicker, Michael Rubino sits down with Alex to discuss why creating a healthy home isn’t about luck. It’s about understanding how buildings work, recognizing small problems before they become big ones, and maintaining the place where we spend nearly 90% of our lives.
Who You’re Listening To: Alex Stadtner
Alex Stadtner is the founder of Healthy Building Science and a Certified Indoor Environmental Consultant and Building Biology Environmental Consultant.
For years, he has helped homeowners, businesses, and organizations better understand how buildings influence health by evaluating indoor air quality, moisture issues, ventilation, and other environmental factors. His work combines technical building science with practical recommendations that help people create healthier indoor spaces.
Your Home Is Part of Your Health
When people think about wellness, they often focus on nutrition, exercise, sleep, or stress management.
Those all matter.
But there’s another factor that’s easy to overlook:
The environment where we spend most of our time.
Our homes influence the air we breathe, the moisture we’re exposed to, the quality of our sleep, and countless other aspects of daily life. Yet many of us don’t think about our homes until something obvious goes wrong, like a roof leak, a burst pipe, or visible mold.
Alex believes that mindset needs to change.
A healthy home isn’t something you achieve once.
It’s something you maintain over time.
What Is Building Biology?
One of the first topics Michael and Alex discuss is building biology, a field focused on how buildings affect human health.
Unlike a traditional home inspection, which is primarily concerned with structural integrity and safety, building biology asks a different set of questions.
How does this home support the health of the people living inside it?
That means looking beyond cosmetic finishes and visible damage to evaluate things like:
- Moisture intrusion
- Ventilation
- Indoor air quality
- Hidden mold
- Volatile organic compounds (VOCs)
- Building materials
- HVAC performance
- Overall environmental conditions
The goal isn’t simply to identify problems.
It’s to understand how the home functions as a living environment.
Every Home Has Room for Improvement
One of Alex’s most memorable quotes from the episode is:
“I’ve never seen a building that couldn’t be made healthier.”
That perspective shifts the conversation in an important way.
The goal isn’t perfection.
It’s progress.
Some homes may have significant issues requiring immediate attention.
Others may simply benefit from improving ventilation, managing humidity more effectively, replacing HVAC filters regularly, or addressing small maintenance issues before they become expensive repairs.
Healthy homes exist on a spectrum, and nearly every home has opportunities to become more supportive of the people living inside.
Why Problems Often Go Unnoticed
Many indoor environmental issues develop quietly.
- A slow plumbing leak.
- Condensation inside a wall.
- A clogged HVAC drain.
- A disconnected bathroom exhaust fan.
None of these necessarily create immediate, obvious warning signs.
Instead, they often progress gradually until moisture, mold, or poor air quality become much larger concerns.
Alex explains that many homeowners don’t realize something is wrong until they experience recurring symptoms or discover damage during a renovation or another unrelated project.
By then, the issue may have been developing for months or even years.
Ventilation: The Missing Piece
Another major takeaway from the episode is the importance of ventilation.
Modern homes are built to be more energy efficient than ever before.
While that’s great for reducing utility bills, tighter construction also means indoor pollutants have fewer opportunities to escape.
Without adequate ventilation, moisture, VOCs, carbon dioxide, and other contaminants can accumulate indoors.
Alex explains that improving ventilation isn’t simply about comfort.
It’s one of the most practical ways to support healthier indoor air.
Fresh outdoor air, properly functioning exhaust fans, and well-maintained HVAC systems all play an important role in creating a healthier living environment.
Maintenance Is Better Than Emergency Repairs
One of the biggest mindset shifts from this conversation is viewing home maintenance as preventative healthcare.
Most of us wouldn’t ignore a strange noise coming from our car for years and expect everything to work out.
- We schedule routine checkups for our health.
- We replace the oil in our vehicles.
- We service our HVAC systems.
Healthy homes deserve the same proactive attention.
Small maintenance tasks today can help prevent larger, more expensive problems tomorrow while also supporting better indoor air quality.
Final Thoughts
One of the most important lessons from this conversation is that healthy homes don’t happen by accident.
They’re built intentionally.
They’re maintained consistently.
And they’re cared for long before visible problems appear.
Just as we invest time in caring for our bodies, our homes deserve the same level of attention.
Because the place we spend the most time has the potential to influence how we feel every single day.
You don’t have to wait for a major problem to start creating a healthier home.
Sometimes the biggest improvements begin with the smallest habits.
Meet Today’s Guest: Alex Stadtner
What makes Alex’s perspective unique is his ability to bridge building science and human health. Rather than looking at a home as simply a structure, he views it as an environment that can either support or challenge the people living inside it.
Throughout this episode, he shares practical advice for homeowners, buyers, and anyone interested in improving their indoor environment. His approach isn’t rooted in fear. It’s rooted in awareness, prevention, and the belief that every home has the potential to become healthier with the right knowledge and maintenance.
