For families across North America

The biggest health risk to your family isn't outside your home. It's already inside it.

The gas in your basement. The mould behind your walls. The water in your pipes. The air your kids breathe every single day. These are the risks your home inspector didn't mention, your doctor can't test for, and your real estate agent had no reason to tell you about.

WellNest families know their home's risks — and their action plan. They're confident their family isn't breathing, drinking, or sleeping next to something that could hurt them.

These risks have been in your home for years — undetected, unfelt, and unnamed. It takes 10 minutes to understand what's putting your family at risk. Most parents say: “I wish I'd known this sooner.”

The risks your home is hiding right now
You've checked the roof. You've replaced the furnace filters. You have a smoke alarm in every room. But the most dangerous risks, routine maintenance never touches.

There are 10 categories of home health risk that routine maintenance doesn't cover — and most of them are completely invisible. Radon gas builds up silently in basements. Mould grows unseen behind drywall. Water contaminants have no taste. VOCs off-gas from furniture you bought last year. Carbon monoxide accumulates before detectors trigger.

This isn't worst-case thinking. These risks are present in the majority of North American homes right now. Your home came with no instructions. No onboarding for homeownership. No manual. No checklist. Most homeowners are doing their best with information they were never given. WellNest is the manual nobody handed you when you moved in.

10 Categories of Home Health Risk

10 ways your home could be working against your family

Every risk below has a dedicated deep-dive guide. Start with the free 9 Invisible Home Risks guide to learn what to look for — then get your Home Wellness Score to see which are most urgent in your specific home.

Radon Gas
High Risk
The number one cause of lung cancer in non-smokers. Colourless, odourless, and accumulating in your basement right now. Nearly 1 in 5 Canadian homes is above the Health Canada action level — and 92% have never tested.
Explore →
💨
Carbon Monoxide
High Risk
Responsible for thousands of preventable deaths annually. Most homes have inadequate detection. CO builds up before alarms trigger — and by then, it may be too late.
Explore →
🔥
Fire Safety
High Risk
It's more than a smoke alarm. Outdated detectors, missing egress windows, overloaded circuits, and improper storage create risk most homeowners have never assessed.
Explore →
🥀
Mould & Moisture
Moderate Risk
1 in 6 homes shows signs of damp or moisture damage. Mould doesn't just cause allergies — it causes structural damage, respiratory illness, and cascading home health problems.
Explore →
🏭
VOCs & Air Quality
Moderate Risk
Your furniture, paint, and cleaning products release chemicals every day. Indoor air is often 2 to 5 times more polluted than the air outside — and you're breathing it 90% of your life.
Explore →
🌬
Ventilation
Moderate Risk
Modern energy-efficient homes are designed to seal in heat. They also seal in CO2, humidity, and pollutants. Proper ventilation isn't optional — it's what makes a tight home healthy.
Explore →
💧
Water Quality
Moderate Risk
Lead, bacteria, and chemical contaminants have no taste, no colour, no smell. What's actually coming out of your taps? Most Canadian homeowners have never checked.
Explore →
HVAC Health
Ongoing
A neglected furnace or dirty filter doesn't just reduce efficiency — it circulates contaminants through every room in your home, all day, every day.
Explore →
🗺
Sump & Drainage
Ongoing
Failing sump systems and foundation cracks are the number one entry point for radon — and the most common cause of basement flooding, mould growth, and structural damage.
Explore →
🩹
First Aid Readiness
Ongoing
When something goes wrong at home, are you prepared to act in the first four minutes? First aid readiness is the last line of home wellness — and one of the most overlooked.

★★★★★
"I assumed our 3-year-old home was safe. The Home Wellness Audit flagged our radon level — we tested and came back at 8x the action level, and got it fixed in one day. I had no idea. Every parent with a basement needs to do this."

★★★★★
"I thought home safety was smoke alarms and CO detectors. The Audit showed me I was missing 7 other categories I'd never thought about. We fixed our sump pit, ordered a radon test, and finally feel like we actually know what's going on in our home."

"My husband thought I was overreacting. Then our Audit came back with radon levels that explained why we'd both been feeling off. We got it sorted fast, and now I finally feel in control of our home. Worth every minute."
