FAQs

  1. If we have mould... Can't we just kill it with bleach?

    NO!  Killing mould growth once established with bleach, a biocide, ultraviolet lights and ozone is not recommended by leading industry associations and is a complete waste of time and money.  Killing mould will only retard its growth for a short period of time.  Dead mould spores can be just as toxic as living mould spores and can have the same health effect on the occupants of the building.  Mould does not behave the same way as bacteria and killing it should not be mistaken as clean-up or removal.

  2. Isn't mould all around us?

    Yes.  However, the genus and species of mould growing indoors are not usually found in large numbers in the outside air.  In addition, the mould that grows indoors tends to be more toxic than mould found outdoors.  If you have a significant mould problem indoors you may be breathing in tens of thousands (or more) spores than you would in a normal environment or outdoors gardening.

  3. If we have mould on drywall, why don't we just tear it out? Do we need an inspection?

    It depends how it got there and how serious the mould issue is.  A small area of mould growth (less than 1 square foot) growing on concrete in a cold cellar can be cleaned up without a mould assessment.  Mould growing on drywall, however, could be an indicator of a more serious mould issue inside the wall.  If the wall is opened without protecting the rest of the area from traveling mould spores, you may be making the problem worse and more expensive to rectify.

  4. We have a new house... Do we really need to have an indoor air quality inspection?

    Yes. The age of the building has no bearing on whether there could be mould, radon, poor air quality, etc.  Newer buildings have more IAQ problems such as VOC chemical off gassing and can also have mould due to poor building design and construction.

  5. We live in Toronto... Do we need to worry about Radon?

    Yes.  We are finding elevated radon levels in many homes in the southern Ontario region.  Radon has been linked to lung cancer and at low levels is equivalent to smoking 1.5 packs of cigarettes per day.  There are multiple factors influencing radon levels, however, it does not produce any odour or any other visible effects.

  6. Our windows have condensation in the winter. Should we replace the windows?

    In some cases the windows will need replacing if they are old and allowing water to intrude into the building.  However, we have found in numerous cases that the problem is actually not the window itself.  If the ventilation in the home is not adequate, replacing the windows may not solve the issue.  In fact, it may make no difference at all.  An air quality assessment would determine the cause of this problem and provide better solutions.

  7. How Dangerous is Radon?

    Radon is a colourless, odourless, invisible natural gas created from the natural breakdown of uranium deep within the earth. If radon testing discovers high levels of radon gas in your home it compromises your indoor air quality, leaving you and your family are at risk: radon gas is the second-most leading cause of lung cancer.

    How Is It Harmful?

    Radon gas particles are small enough to be inhaled. These radioactive particles settle in the respiratory system and cause damage, scarring, and cellular changes as they break down, leading to lung disease and cancer.

  8. What Causes Radon at Home?

    What Causes Radon at Home?

    Radon gas is on the lips of anyone concerned about their home’s indoor air quality. This colourless, odourless, invisible gas is only detectable through specialized radon testing and affects thousands of homes across Ontario. At SafeAir, many of our customers have never heard about radon gas and wonder why they should test for it — well, here are some answers! 

    What is Radon?

    radon testing indoor air qualityRadon gas is created as uranium decays. Deposits of this radioactive substance are buried deep in the earth’s crust, and as the gas floats to the surface, it can collect in our homes instead of safely dispersing into the atmosphere. Many people are surprised to learn that radon gas is the second-most leading cause of lung cancer after tobacco smoke — the tiny particles of radon gas cause cellular changes, inflammation, and damage to the lungs when we breathe them in.

    How Does Radon Get into My Home?

    The risk of cancer associated with long-term radon gas exposure means preventing exposure is critical. If SafeAir detects radon gas in your indoor air quality, the next step is to determine how it’s getting in and seal up any entrance points. 

    Here are a few common ways radon gas gets inside homes. 

    • Soil: Radon gas is naturally occurring and moves up to the surface through the soil underneath our homes. Buildings with dirt basements or exposed soil in their lower levels are at particular risk for radon gas because of the porous nature of soil.
    • Cracks and Gaps: The primary way that radon tends to make its way into homes is through cracks and gaps in the foundation. Cement, bricks, or slab foundations can develop cracks as they age and settle. Pipe holes or intrusions into your foundation also break the barrier and may let radon enter.
    • Rocky ground: Homes built on rocks or in rocky areas may be at an elevated risk for radon gas because rocks may contain more extensive deposits of radioactive material. More uranium equals higher concentrations of radon gas and a greater likelihood it will affect your home at unsafe levels.
    • Wells: Home wells or sump drainage ports often cause increased radon gas in the home. Well water can be in more significant contact with rocks and soil containing radon, carrying it into your home. Open sump drains can be sealed to allow water in, but no radon gas out. 

    Why Radon Test With SafeAir

    One of the reasons radon gas is so dangerous is that it’s impossible to detect with our senses alone. That’s why SafeAir offers reliable and trustworthy radon testing in Toronto and the GTA. These small, unobtrusive tests require only a few moments to install in your home; six months later, we return to uninstall them and send the device off to a lab for testing. Radon can fluctuate throughout the year, and tests must be placed precisely to obtain accurate results. Once we have your results, SafeAir can suggest strategies to mitigate your risk and reduce radon levels in your home. To inquire about radon testing or our indoor air quality tests, contact the SafeAir team directly.
