Mold Remediation
Certified mold removal that protects your family's health and prevents recurrence — for homes across the Greater Toronto Area.
About Mold Remediation
Mold is a silent problem. It thrives in the exact places homeowners don't check regularly — behind drywall, under bathroom vanities, inside basement wall cavities, in the corners of finished basements. By the time you see the black or greenish patch, spores have often already spread through the surrounding materials and into the air you breathe.
Val Restoration Group provides certified mold remediation across the Greater Toronto Area, following strict containment and removal protocols designed to protect your family's health, save as much of your existing finishes as possible, and — most importantly — address the moisture source so the mold doesn't return.
This page explains how mold gets started in GTA homes, the warning signs to watch for, the risks of leaving it untreated, and exactly how our mold remediation process protects your home from the first inspection through post-remediation clearance.
What's included
- Containment & HEPA filtration
- Safe removal protocols
- Anti-microbial treatment
- Air quality testing (additional cost)
Common causes
- •Unresolved water damage from leaks, floods, or burst pipes
- •High indoor humidity, especially in basements and bathrooms
- •Poor ventilation in laundry rooms, ensuites, and kitchens
- •Foundation seepage and window well leaks
- •Condensation on cold water pipes and uninsulated ductwork
- •Roof leaks and ice damming that soak attic insulation
- •Wet building materials sealed inside walls during renovations
- •Damp carpet and pad left in place after even minor water incidents
Warning signs to watch for
- •Visible black, green, brown, or white patches on walls, ceilings, or grout
- •A persistent musty or earthy smell
- •Discoloured or stained drywall and baseboards
- •Peeling paint, bubbling wallpaper, or warped trim

- •Condensation on windows or cold surfaces
- •Recent history of water damage that wasn't fully dried
- •Dark spots around vents, in closets, or behind furniture on exterior walls
Why act quickly
Risks of leaving it untreated
Small problems escalate fast. Here's what's on the line when a mold remediation issue is ignored.
Respiratory issues: coughing, wheezing, and worsening asthma
Allergic reactions: sneezing, itchy eyes, skin irritation
Sinus infections and chronic headaches
Increased risk for immunocompromised residents, infants, and elderly family members
Structural damage as mold breaks down wood framing and drywall
Reduced property value and issues during home sales and inspections
Our Process
From inspection to full resolution
A clear, proven sequence — so you always know exactly what's happening next.
- 01
Inspection & moisture mapping
We identify visible mold and use moisture meters and thermal imaging to find hidden growth inside walls, ceilings, and floors.
- 02
Air quality testing (optional, additional cost)
Third-party lab sampling confirms spore types and concentration before and after the work — recommended for health-sensitive households.
- 03
Containment setup
We isolate the work area with 6-mil plastic barriers and negative air pressure so spores don't spread to the rest of your home.
- 04
Safe removal
Affected porous materials are bagged and removed; salvageable surfaces are HEPA-vacuumed, damp-wiped, and cleaned according to industry remediation protocols.
- 05
Anti-microbial treatment
EPA-registered antimicrobial products are applied to inhibit regrowth on cleaned surfaces and framing.
- 06
Moisture source correction & rebuild
We correct the underlying moisture source, rebuild what was removed, and provide documentation confirming the area is safe.
Equipment & Technology
Professional-grade tools for professional results
We invest in commercial equipment because mold remediation done right depends on the right technology in the right hands.
HEPA air scrubbers with negative air machines
Capture 99.97% of airborne particles down to 0.3 microns and maintain negative pressure inside containment.
HEPA vacuums
Safely collect settled spores and debris from cleaned surfaces without recirculating them.
Moisture meters & thermal imaging cameras
Find hidden moisture — the root cause of mold — before, during, and after remediation.
6-mil plastic containment barriers
Isolate the work zone completely so spores can't drift into clean areas of the home.
Personal protective equipment (PPE)
Full Tyvek suits, N95/P100 respirators, and gloves protect our techs — and your indoor air — during removal.
EPA-registered antimicrobials
Treat framing and salvaged surfaces to inhibit regrowth after removal.

Insurance
We work with your insurance
Coverage for mold in Ontario depends on the cause. Mold that results from a sudden covered event — like a burst pipe — is often covered when reported promptly. Mold from gradual leaks or long-term humidity typically isn't. We help you understand where your claim likely stands and provide the moisture readings, photos, and scope documents your adjuster will ask for.

Frequently asked questions
Mold Remediation FAQs
Is all mold dangerous?
Not all mold is equally harmful, but any indoor mold growth signals excess moisture and should be addressed. Some strains — including certain black molds — can cause serious respiratory issues, especially for sensitive individuals.
Do I need air quality testing?
It's optional but recommended when there are health-sensitive residents (children, elderly, immunocompromised) or when you want documented proof that clearance was achieved. Testing is billed separately.
Can I stay in my home during mold remediation?
In most cases, yes. Our containment keeps the work area sealed off. If the affected area is large or in a central space, we'll discuss temporary relocation with you.
How long does mold remediation take?
Small, localized jobs can be completed in 1–2 days. Larger remediations with extensive tear-out and rebuild may take 1–2 weeks.
Will the mold come back?
Not if the moisture source is corrected. Our process addresses the root cause — plumbing leaks, humidity, ventilation — so the same problem doesn't return.
Do you handle black mold specifically?
Yes. All visible mold is treated with the same containment and safety protocols regardless of colour or species.
Can you remediate mold in condos and rental units?
Yes, we work with condo owners, landlords, and property managers across the GTA and can coordinate with building management as needed.
What does mold remediation cost?
Cost depends on the size of the affected area, materials involved, and whether reconstruction is required. We provide a written quote after the inspection with no obligation.
