Mold Remediation
& Removal
Professional mold assessment, containment, and removal for Ontario homes and commercial buildings. Commercial-grade equipment, EPA-registered disinfectants, and verified clean results on every job.
Mold Doesn't Stay in One Place
Mold in your attic, crawlspace, or basement isn't a cosmetic issue. Left untreated, it spreads through your building envelope, compromises insulation effectiveness, and degrades air quality throughout the property. In commercial buildings, it creates liability. In homes, it affects health.
We see mold in a significant portion of the attic spaces we inspect — most often from inadequate ventilation, past roof leaks, or moisture that built up under old insulation. The critical step is proper remediation before any new insulation goes in. Covering mold with new material just delays the problem.
Health risks associated with mold exposure
before & after
Why Professional Remediation Is Non-Negotiable
Containment Prevents Spread
Professional remediation uses negative air pressure containment barriers to isolate affected areas. Without this, disturbing mold colonies sends spores airborne — contaminating previously clean areas of the building.
Commercial-Grade Products
We use EPA-registered disinfectants and antimicrobial agents that household cleaners can't match. These products are formulated to kill mold at the root — not just bleach the surface appearance away.
Verified, Documented Results
Every job is documented with photos before and after. We don't just treat and leave — you receive visual confirmation that the remediation was completed properly before insulation is reinstalled.
Our Mold Remediation Services
The most common location we find mold in Ontario homes. We contain the affected area, remove all contaminated material, treat structural wood surfaces, apply commercial-grade disinfectant, and fog the space to kill any remaining spores.
- Negative air containment before any disturbance
- Full extraction of contaminated insulation
- HEPA-filtered air scrubbers throughout process
- EPA-registered antimicrobial application to wood
- Disinfectant fogging of the entire space
- Photo documentation before & after
Below-grade spaces trap moisture and create ideal conditions for mold growth. Often invisible until insulation is removed during a renovation or inspection. We treat the source, not just the surface.
- Moisture source assessment included
- Removal of all contaminated materials
- Antimicrobial treatment on concrete and wood
- Fogging and air scrubbing of the space
- Recommendations to prevent recurrence
Hospital-grade disinfectant fogging penetrates every corner of the affected space, neutralizing airborne spores and surface contamination. Applied after removal as a final clean — and available as a standalone treatment for lighter contamination.
- Hospital-grade disinfectant compounds
- Reaches all surfaces including hard-to-access areas
- Kills mold spores and bacteria on contact
- Safe for reoccupancy after proper ventilation
- Available as standalone or part of full remediation
Not sure if you have mold? We inspect attic, crawlspace, and below-grade areas to identify contamination, assess severity, and give you an honest recommendation — whether that's full remediation or a targeted treatment.
- Visual inspection of all accessible areas
- Identification of mold type and spread
- Moisture source assessment
- Written scope of recommended work
- No obligation — we tell you what we find
After mold is removed and the space is verified clean, we reinstall insulation to the correct R-value. One team, start to finish — no coordinating between multiple contractors.
- Full attic or crawlspace insulation reinstall
- Blown-in fibreglass or cellulose to R60
- Air sealing completed before reinstall
- Before & after photos on completion
- Eligible for rebate programs after remediation
Hotels, office buildings, multi-unit properties, and retail spaces. We work around your schedule to minimize disruption. Containment protocols designed for occupied commercial properties.
- Phased scheduling for occupied properties
- Negative pressure containment throughout
- Liability documentation provided
- Suitable for hotels, offices, multi-unit buildings
- Emergency response available
How We Handle Every Job
Assessment
We inspect the affected area, identify mold type and extent, and assess the moisture source.
Containment
Negative air pressure barriers isolate the work area before any disturbing begins.
Removal
Contaminated material is extracted using HEPA-filtered vacuums and industrial equipment.
Treatment
Structural surfaces are treated with EPA-registered antimicrobials. Space is fogged.
Verify & Reinstall
Results documented with photos. Insulation reinstalled once clearance is confirmed.
Commercial Equipment,
Professional Results
We don't use household products. Every step of our remediation process uses commercial-grade equipment and EPA-registered compounds that are specifically formulated for mold remediation — not general cleaning.
HEPA Air Scrubbers
Continuous negative air filtration during remediation captures airborne spores at 99.97% efficiency.
Commercial GradeEPA-Registered Antimicrobials
Hospital-grade biocides formulated to kill mold at the cellular level — not just bleach the surface.
EPA RegisteredThermal Fogging Equipment
Penetrates cavities and surfaces that manual application can't reach. Used as final treatment.
Full CoverageIndustrial Vacuum Extraction
HEPA-filtered extraction removes all contaminated insulation and debris safely and completely.
Zero SpreadSigns You May Have
a Mold Problem
Musty or earthy odour
A persistent musty smell in your attic, basement, or crawlspace is one of the most reliable indicators of hidden mold growth — even before any visible signs appear.
Dark staining on wood or insulation
Black, green, or grey discolouration on attic sheathing, joists, or insulation is often mold. Can appear as fuzzy patches or flat surface staining.
Recent water damage or roof leak
Any past water intrusion creates conditions for mold. If you had a leak and didn't have the attic inspected afterward, there may be growth you're not aware of.
Persistent coughing or allergy symptoms indoors
If occupants experience symptoms that improve when they leave the building, mold contamination in the envelope or HVAC system may be the cause.
Buying or selling a property
Attic mold is commonly discovered during home inspections. If a report flagged it — or if you're about to list and haven't had an inspection — book an assessment first.
