Trusted Mold Removal in Markham

Pro Max Restoration provides professional mold removal, testing and remediation across Markham. From damp basements in Unionville and Milliken Mills to attic condensation in Cornell and Greensborough and bathroom mold in high-density Markham Centre condos, our IICRC S-520-certified team identifies the species and moisture source, contains it safely, removes it, and verifies the air is clean before we rebuild.

Markham's mix of heritage homes and fast new construction each create their own moisture risks — from aging drains and damp older basements to the sealed envelopes of new builds that trap humidity. We never disturb significant growth without HEPA-filtered containment and negative air pressure, and every Markham project ends with post-remediation clearance testing so you have documented proof your home is safe.

  • Air-quality and surface testing with species identification

Markham Mold Risks We See Most

After 600+ GTA restoration projects, we know exactly how Markham homes are affected — and how to fix it for good.

Basement Humidity & Foundation Leaks

Older Markham homes in Unionville and Milliken Mills with foundation seepage or past flooding are a common source of hidden mold, where persistent moisture behind finished walls feeds growth.

Attic Condensation in New Builds

Markham's rapid growth means many sealed, well-insulated homes in Cornell, Berczy and Greensborough trap moisture, and poor attic ventilation leads to widespread attic mold discovered at inspection.

Post-Flood & Post-Leak Mold

Any water damage not dried to standard within 24–48 hours grows mold. We frequently remediate mold left behind by a previous Markham flood or leak that was cleaned up incompletely.

Mold almost always traces back to a moisture source — a leaking basement, a past water damage event, or poor ventilation. We fix the source and verify the air — request a free quote.

IICRC-Certified Mold Removal Across Markham

Mold in a Markham home is a moisture problem first and a mold problem second, and Markham's diverse housing stock gives moisture plenty of places to hide. The heritage homes of Unionville and older Milliken Mills contend with aging drains and damp basements, while the fast-built, tightly sealed homes of Cornell, Berczy and Greensborough trap indoor humidity and suffer attic-ventilation shortcomings. Our IICRC S-520-certified technicians begin by identifying the true source, because surface treatment alone allows the mold to return.

Our remediation follows the IICRC S-520 standard end to end: inspection and air-quality or surface testing to establish the species and extent, HEPA-filtered containment with negative air pressure so spores cannot spread through your home, physical removal of affected materials, antimicrobial treatment, and post-remediation clearance testing that confirms the air is safe before any rebuild. Containment is never optional — disturbing mold without it spreads the problem.

Because mold follows water, we resolve the source behind it — a leaking basement, past flood damage, condensation or ventilation issue — coordinating with our water damage and waterproofing teams so the whole problem is fixed in one project. With 15+ years of experience, 600+ restored GTA properties, a 5.0 Google rating and documented clearance results, Pro Max Restoration gives Markham homeowners mold removal that lasts.

Markham FAQ

Mold Removal in Markham — Your Questions Answered

How do I know if I have mold in my Markham home?
Warning signs include a musty smell, visible black or green spotting, peeling paint, and worsening allergy or asthma symptoms indoors. We offer air-quality and surface testing to confirm it before work begins. Call 416-577-2877.
Do you serve Unionville and Cornell?
Yes — we cover all of Markham, from heritage Unionville and Milliken Mills to the newer Cornell, Berczy and Greensborough communities, and we know the moisture risks specific to each.
Is black mold in my home dangerous?
Black mold (Stachybotrys) can release mycotoxins linked to respiratory irritation and allergic reactions. We use HEPA containment and negative air pressure so spores do not spread through your Markham home during removal.
Will the mold return after removal?
Only if the moisture source remains. Every Markham job includes fixing the underlying cause and post-remediation clearance testing to confirm the air is safe before we rebuild.
