Indoor Air Quality Testing Services

Protect Your Health. Know What You’re Breathing.

Our advanced air testing services are designed to detect invisible but dangerous pollutants like VOCs (Volatile Organic Compounds), formaldehyde, active mold, and tobacco smoke residue — all without disrupting your home’s interior.

Indoor air quality plays a major role in your health, comfort, and long-term well-being — especially here in Quebec, where the average person spends over 85% of their time indoors. Whether you’re buying a property or concerned about the home you’re living in, Mose Home Inspection offers professional indoor air quality testing to give you peace of mind, clear, reliable answers you need, to protect your family.

Why Test Indoor Air Quality?

Most people assume indoor air is safer than outdoor air

often without knowing what’s really in the air they’re breathing. In reality, indoor air is often much worse. Common household materials, hidden water damage, poor ventilation, and heating systems can release toxic gases and allergens into the air.

Exposure to poor air quality has been linked to:

  1. Chronic allergies
  2. Asthma and asthma attacks
  3. Breathing difficulties
  4. Fatigue, dizziness, and
  5. headaches
  6. Skin and eye irritation
  7. Long-term respiratory illness

Infants, children, seniors, and those with sensitivities are especially vulnerable.

How the Testing
Process Works

How the Testing Process Works
1. Using professional-grade sampling equipment, your Mose home inspector will collect air samples from your property.
2. Samples are sent to an accredited and certified laboratory for advanced analysis
3. The lab analyzes over 400 VOCs, mold toxins or formaldehyde levels
4. You receive a full report, detailed and easy-to-understand, that identifies pollutants and their likely sources, whether levels are considered safe, elevated or hazardous
5. Our team is available to explain the results and recommend next steps for improving indoor air quality
6. Testing is fast, non-invasive, and can be done as a standalone service or added to your full home inspection.

What We Test For

Using professional-grade sampling equipment, your Mose home inspector will collect air samples from your property. These samples are sent to an accredited lab and, depending on the analysis selected, tested for:

  • Over 400 VOCs (Volatile Organic Compounds)
  • Formaldehyde
  • Airborne Mold MVOCs actively growing mold)
  • Tobacco smoke residue (second-hand and third hand)
  • Poor insulation-relate emissions
  • Contaminants from building materials, paint, varnish, adhesives, and household products and furnishings

You’ll receive a detailed, easy-to-understand report that outlines detected chemicals, their likely sources, and whether levels are normal, elevated, or hazardous.

What Are VOCs — And
Why Should You Be Concerned?

VOCs are TOXIC GASES (Volatile Organic Compounds) released by many materials and products inside the home — even when those products are not in use. Most VOCs are odorless and can’t be detected without proper testing.

Common VOCs we detect include:

  • Alcohols
  • Aromatics
  • Aldehydes
  • Freons
  • Esters
  • Hydrocarbons
  • Ketones

Detecting Active Mold
in the Air

Mold isn’t always visible. Our specialized equipment detects MVOCs (mold volatile organic compounds) which are released by actively growing mold, even when it’s hidden behind walls, under flooring, or above ceilings. This method is non-invasive and avoids disturbing the mold, which prevents cross-contamination.

We’ve seen mold growing in and around:

  • Basements with moisture intrusion
  • Sump pumps and damp crawl spaces
  • Behind walls with water damage
  • Around plumbing or roof leaks
  • Around condensation-prone windows and walls
  • Under sinks or in humid areas
  • Air Conditioning units —HVAC drain lines and drip pans
  • Indoor plants or damp storage areas
  • Insulation and wall cavities
    Outdoor mould near air intakes

Formaldehyde Detection

Formaldehyde is a highly toxic chemical often found in homes, especially those with:

  • Pressed wood products (like MDF and particleboard) and laminate flooring
  • Foam insulation and furniture and glue-based resins
  • Household fabrics and drapes
  • Carpeting
  • Cigarette smoke

At room temperature, formaldehyde turns into a gas and becomes airborne. It is a known human carcinogen and can lead to:

  • Burning of the eyes, nose, and throat
  • Skin irritation and rashes
  • Respiratory problems
  • Nausea and dizziness
  • Asthma triggers

Formaldehyde is often undetectable without proper testing, which is why it’s important to test any home.

At Mose Home Inspection, we test for formaldehyde and help identify its sources so you can protect your family.

Tobacco Smoke
Detection: Second-
hand & Third-Hand
Exposure

As part of your indoor air quality test, your inspector will test for:

  • Second-hand smoke (environmental tobacco smoke)
  • Third-hand smoke (residue that lingers on surfaces, fabrics, and walls)

Third-hand smoke (residue that lingers on surfaces, fabrics, and walls), Is the secondhand smoke coming from a neighbor? Our tobacco test is not as sensitive for this situation; detection works best in areas where the smoker lives.

Is Your Home Truly
Smoke-Free?

Even if a home “smells clean,” it may still contain invisible residue from tobacco use. Our testing methods can help confirm whether a home is truly smoke-free — a key concern for families, landlords.

Even if a property smells clean or seems smoke-free, residue from past smoking can linger for years, especially in ventilation systems and porous materials. Our lab testing can detect these compounds, even when odor is no longer present.

This is especially important for families with young children, seniors, people with asthma and anyone sensitive to tobacco exposure.

Is Your Home Really Safe
to Breathe In?

You can’t see most of the toxins that affect your health. Whether you’re a buyer, seller, or homeowner, indoor air quality testing helps you understand what you’re breathing — and how to fix it.

With Mose Home Inspection, you’ll get:

  • Certified testing
  • Trusted equipment and lab analysis
  • Clear, detailed reporting
  • Friendly, professional support

What Our Clients Are
Saying

P

J'ai eu la chance de travailler avec Renaud Lévesque pour l'inspection de mon condo à Montréal. Il a été d'un professionnalisme impeccable, d'une gentillesse exemplaire et d'une aide précieuse. Il est allée au-delà de son mandat pour me montrer comment entretenir certains appareils et a pris le temps de m'expliquer ce que ses observations voulaient dire. J'ai beaucoup apprécié et je le recommande très chaudement. Merci Renaud

Overall good experience from booking the inspection to after the completion of the inspection. Andrew, the inspector, was very nice, respectful, professional, thorough and helpful. He was good at explaining things, and even made himself available after the inspection for any related questions. I am glad I chose Mose.

A

Our inspector from Mose, Micheal Kallaur was excellent. He inspected 2 homes for us and one of them was a bit of a tricky situation. He went above and beyond to make sure the home was properly inspected, even going back a second time (asap) as a certain area was impassable the first time. Micheal made us feel like we could trust him now and in the future should we have any concerns about the home we purchased. 10/10 recommend.

L

My husband and I purchased our first home and Carol came highly recommended as an inspector and we couldn't be happier with her services! She was prompt and responsive over email and found the availability to come inspect our new home within just a few days at our request. She spent a lot of time going over every detail and making us aware of all the issues with the house in a professional and friendly manner. We felt confident in our purchase and well informed on minor repairs that arose. She was wonderful and we'd book her/recommend her to others in a heartbeat!

As a first time home-buyer all the steps in the process are new to me. Gerry patiently explained to me what he was checking and his preliminary results as he went. Not only that he gave tips & tricks on certain maintenance tasks I would have had to figure out completely on my own. Top notch service!
