How It Works
Our Mold Remediation Process
Inspection & Testing
We inspect the property and use air and surface sampling to confirm the type of mould and map every area affected, including hidden growth.
Containment
We seal off the work area with physical barriers and negative-air HEPA machines so spores are captured rather than spread through the building.
Removal & Cleaning
Mould is physically removed from affected materials, surfaces are HEPA-vacuumed and treated with antimicrobials, and contaminated porous materials are disposed of.
Clearance & Restoration
We arrange post-remediation verification to confirm the air is clean, then restore any removed drywall, insulation, and finishes.
Professional Mold Inspection & Removal Across the GTA
Mould is more than an eyesore: it is a health hazard and a sign of an underlying moisture problem that will keep coming back until it is fixed properly. Toronto's older housing stock, finished basements, and humid summers make mould one of the most common indoor air-quality issues we deal with across the Greater Toronto Area.
Restoration Services GTA provides certified mold inspection, testing, and remediation for homes and businesses throughout the GTA. Our IICRC-certified crews don't just scrub the surface: we find the moisture source, contain the area so spores can't spread, physically remove the mould, and verify with third-party testing that the air is safe again. The result is documented, defensible proof that the problem is gone, not just hidden.
Why Mold Is a Health and Property Risk
Mould releases microscopic spores into the air you breathe, and prolonged exposure can affect everyone in the building, not just people with allergies. Beyond health, mould degrades the materials it grows on and is a serious red flag during any property sale or inspection.
- Triggers allergies, asthma, coughing, congestion, and eye and skin irritation.
- Poses greater risks to children, seniors, and anyone with respiratory conditions.
- Rots wood, crumbles drywall, and damages insulation as it spreads.
- Lowers property value and routinely derails home inspections and sales.
What mould needs to grow
Mould requires only three things: moisture, an organic food source like drywall or wood, and time, as little as 24 to 48 hours. Remove the moisture and you remove mould's ability to return, which is why every remediation we do starts by identifying and addressing the water source behind the growth.
Where We Find Mold in GTA Homes
Mould thrives wherever moisture lingers and air doesn't move. In the homes we serve across Toronto and the surrounding regions, these are the usual hotspots:
- Finished and unfinished basements
- Bathrooms, behind tile, and around showers
- Attics with poor ventilation or roof leaks
- Crawl spaces and beneath subflooring
- Behind drywall after a water leak or flood
- Around windows from condensation
- Inside HVAC systems and ductwork
Why You Should Never Just Paint Over Mold
It is tempting to wipe mould with bleach or paint over a stain and move on, but that does not remediate anything; it hides the problem while the colony keeps growing inside the material and the moisture source keeps feeding it. Proper remediation follows a strict, verifiable process.
Containment first
Disturbing mould without containment is the fastest way to spread it. We seal the work zone and run negative-air HEPA machines so spores are pulled out of the air and captured, protecting the rest of your home during removal.
Physical removal, not masking
Mould has to be physically removed from the materials it has colonized. We remove and dispose of contaminated porous materials, HEPA-vacuum and clean salvageable surfaces, and treat them with antimicrobials; fogging or painting over growth is never a substitute.
Verification at the end
We finish with post-remediation verification so you have independent, documented proof the air is clear. That clearance is what protects you during a sale, an insurance claim, or a tenant dispute.
Mold and Your Insurance Claim
Mould coverage depends on the cause. When mould results from a sudden, covered water loss, such as a burst pipe or appliance failure, remediation is often covered as part of that claim. Mould from long-term, unaddressed leaks or humidity is typically not covered, which is another reason to deal with water damage immediately.
We help you navigate this. We document the source and extent of the mould to insurer standards, advise honestly on what is likely covered, and bill your insurer directly where coverage applies. Either way, you get a clear scope and a defensible record of the work performed.

Frequently Asked Questions
How do I know if I have a mold problem?
Common signs are a persistent musty smell, visible discolouration on walls or ceilings, and worsening allergy symptoms indoors. If you suspect mould but can't see it, our air and surface testing will confirm whether it's present and how widespread it is.
Do you provide a clearance certificate after remediation?
Yes. We arrange post-remediation verification testing so you have independent, documented proof the space is clear, important for home sales, insurance claims, and your own peace of mind.
Is bleach enough to kill mold myself?
No. Bleach may lighten a surface stain but doesn't remove mould from porous materials or address the moisture feeding it, and disturbing mould without containment spreads spores. Anything beyond a small surface patch should be handled with proper containment.
What causes mold to keep coming back?
An unaddressed moisture source. If a leak, humidity problem, or drainage issue isn't fixed, mould will return no matter how well it's cleaned, which is why we identify and address the source as part of every remediation.
Will my insurance cover mold removal?
Often, if the mould results from a sudden covered water loss like a burst pipe. Mould from long-term leaks or humidity is usually excluded. We document the cause to insurer standards and advise you honestly on coverage.
Is the mold in my home toxic?
Some moulds produce mycotoxins, but all indoor mould should be treated as a health risk and removed properly. Rather than guess, our testing identifies what's present so the remediation is matched to the situation.
