Stop mould in its tracks.

A mould problem at home is a challenge no homeowner should face alone. If you’re seeing signs mould, it’s time to act — and we can help!

Mould in the home is a significant health hazard and specifically dangerous for those with allergies, asthma or mould sensitivity. Not to mention the musty smell and characteristic stains it leaves behind.  

We’ll eliminate the harmful fungus and its spores from your entire home so you can breathe easy. Let us do the dirty work! 

Rather than tearing down your drywall, which is invasive and costly, we’ll use our patented Dry Fog technology to reach every nook and cranny. By treating mould this way, your family only needs to leave home for a few hours — no cleanup or reconstruction needed!

  • How effective are mould remediation treatments?

    Our Dry Fog treatments are highly effective, verified and 100% guaranteed, or we re-treat your home for free. If we're able to resolve all moisture and water issues, this is a permanent solution to your mould issue.

  • Are mould treatments safe for my family, including my pets?

    Dry Fog treatments are safe. Once the vapour has dispersed, you and your pets can return home safely. Our treatments are non-invasive, non-toxic, Health Canada and EPA-registered. This treatment will not harm the contents of your home.

  • How should I prepare for my mould remediation appointment?

    We’ll contact you a few days before your appointment to go over what to do before we arrive. It's simple to prepare for this appointment and we’ll ask that you leave doors and closets open and ready for the service.  

    You do not need to remove your belongings from the home prior to treatment. In fact, you should leave as many of your belongings inside the home as possible. Mould spores get trapped inside fabrics, furniture, clothing, mattresses and other porous surfaces, so treating your belongings is an important part of mould remediation.

  • Should I be present during the Dry Fog Treatment?

    Your family and pets will need to leave your home for the duration of the treatment, so plan a place for you and your pets to be during the service.

  • Will Dry Fog harm my paintings or wall art?

    This treatment is dry and will not mark, damage or degrade wall hangings. Some people cover wall art with sheets or remove it for the duration of the service, but this isn’t necessary.

  • Should I store away fruit or other foods left out in the kitchen?

    Our InstaPure and EverPURE products are FDA-approved for food contact, but feel free to store food in a zip lock bag or refrigerator to ensure freshness.

  • Will the Dry Fog Treatment get behind my walls?

    Any place where a mould spore can get in or out of will be penetrated by the fog treatment. If there's a deeper issue, we can poke a few small holes between the studs and treat the back of the wall directly.

  • How long before I can return home?

    You'll be back in your home the same day of the treatment. On average, you can expect the service to take 3–4 hours, depending on the outdoor temperature and if windows can be opened after. You may notice a vinegar-like smell when you return, but this smell is harmless and will disperse within a few hours. 

  • What will the mould look like after the treatment?

    Mould leaves ugly stains behind, even after the fungus has been removed. We can clean mould stains for a small additional cost. With the harmful mould removed, you can also do this as a DIY project!

  • What do I need to do post-treatment?

    Nothing! Our mould treatments leave no residue, so your home and all items in it will be clean afterwards. There’s no need to clean fog residue from your belongings post-treatment.
