Attic Mould Removal with Dry Ice Blasting & Ozone Treatment
Why Attics Are Vulnerable​
​
Crawlspaces are dark, damp, and often poorly ventilated — the perfect environment for mould. Once mould establishes itself on wood, insulation, or vapour barriers,
it doesn’t just sit on the surface. Mould sends roots (hyphae) deep into porous wood, making it extremely difficult to remove completely with traditional methods.
Why Traditional Chemical Cleaning Fails
​
Most conventional crawlspace mould treatments rely on spraying chemical solutions. While these chemicals may bleach or kill mould on the surface, they cannot penetrate
deep enough into the wood to destroy the root system.
-
Surface-only cleaning – Leaves hidden mould roots behind.
-
Temporary fix – As soon as moisture or humidity reappears, the mould simply grows back from the surviving roots.
-
Chemical residue – Introduces harsh substances into the home environment, which can pose risks to occupants and pets.
This is why many crawlspaces treated with chemicals experience recurring mould problems.
​
The Dry Ice Blasting Difference
​
Dry Ice Blasting is a non-toxic, non-chemical, and permanent solution for mould removal. Instead of just bleaching the surface,
it physically removes the entire mould colony, surface growth and roots.
Here’s how it works:
-
Thermal Shock – The extreme cold (-78°C) makes mould brittle and detaches it from surfaces.
-
Deep Cleansing – High-velocity impact dislodges mould spores and their root systems from porous wood grain.
-
Sublimation – The dry ice pellets vaporize instantly into COâ‚‚ gas, expanding beneath the surface and lifting contaminants away without leaving secondary waste.
Because the roots are eliminated, mould cannot re-establish itself as soon as moisture returns — making this the most thorough remediation method available.
​
Ozone Application (Optional Premium Treatment)​
​
To take remediation to the next level, we offer ozone treatment immediately after dry ice blasting.
-
Airborne Spore Eradication – Ozone penetrates the entire crawlspace, neutralizing any remaining airborne mould spores and bacteria that blasting may have dislodged.
-
Odour Elimination – Removes musty crawlspace odours often associated with mould.
-
Sanitization – Creates a cleaner, healthier environment by sterilizing surfaces and air.
By combining dry ice blasting (root removal) with ozone application (air and surface sanitization),
we deliver a complete remediation system that not only cleans your crawlspace but also reduces the risk of recurrence.

Dry Ice Blasting removes the roots. Ozone kills what’s left in the air. Together, they provide the most thorough crawlspace mould remediation available.
Crawlspace Mould Removal with Dry Ice Blasting & Ozone Treatment
​
​
Crawlspaces are one of the most vulnerable areas in any home. Poor ventilation, damp soil, and fluctuating temperatures create the perfect breeding ground for mold. Once it takes hold,
it doesn’t just live on the surface—it embeds its roots deep into porous wood and structural materials.
Many homeowners and even contractors mistakenly turn to bleach, chemical sprays, or “wipe-downs” as a solution. The problem? These methods only kill surface mold.
The roots remain alive beneath, waiting. As soon as moisture returns—which it inevitably does in a crawlspace—the mold quickly grows back, often worse than before. This is why traditional methods rarely provide lasting results.
The Dry Ice Blasting Difference
​
Our solution is different. Dry ice blasting uses high-velocity frozen COâ‚‚ pellets to physically
strip mold off surfaces down to theroot structure without chemicals, without secondary waste,
and without damaging the wood. It doesn’t just clean—it restores the substrate,
leaving behind a mold-free surface that’s ready to stay that way.
Benefits Of Dry Ice Blasting:
-
Penetrates deep into cracks, pores, and fibers where mold roots live.
-
Chemical-free and environmentally friendly—safe for your family and pets.
-
No secondary mess—the dry ice sublimates into gas, leaving only removed debris to vacuum away.
-
Fast and thorough, tackling areas traditional sanding or scrubbing can’t reach.
Optional Premium Protection: Ozone Application
​
For homeowners seeking maximum peace of mind, we also offer ozone treatment as a premium add-on. After dry ice blasting, we flood the crawlspace
with controlled ozone gas, which penetrates the entire environment—air, surfaces, and even microscopic spaces.
Ozone neutralizes any residual spores and eliminates odors, leaving the space fresh, sanitized, and inhospitable to mold regrowth.
Benefits of ozone treatment:
-
Kills airborne spores missed by physical cleaning.
-
Removes musty odors, leaving a clean, fresh environment.
-
Adds an extra layer of assurance for long-term protection.
Why Choose Us
​
By combining dry ice blasting with the option of ozone sterilization, we deliver a complete crawlspace remediation solution
that doesn’t just hide mold—it eradicates it at the root and helps keep it from coming back.
Your crawlspace may be out of sight, but it shouldn’t be out of mind. Protecting it protects your home’s
structural integrity, indoor air quality, and your family’s health.
