Mould in a commercial building isn’t just ugly. It’s a liability waiting to happen.
Under Ontario’s Occupational Health and Safety Act, you’ve got a legal obligation to provide a safe workplace. If tenants or employees start complaining about respiratory issues and it turns out there’s been mould growing behind the walls for six months, that’s a problem no amount of air freshener is going to fix. And the longer it sits, the worse it gets – both the mould itself and the cost of dealing with it.
Brampton’s climate doesn’t help. Humid summers, freeze-thaw cycles that create condensation in poorly ventilated spaces, older commercial buildings with original plumbing that’s well past its prime. It all adds up to a city where commercial mould problems are surprisingly common.
Here are six companies that handle mould remediation for commercial properties in the Brampton area. I focused on companies with proper certifications, commercial-scale experience, and processes that actually address the root cause – not just the visible growth.
1. Impact Restore
Best for: Containment Done Right in Commercial Spaces
Here’s a scenario that happens more often than you’d think. A property manager spots mould behind a wall in one suite, calls the cheapest crew they can find, and those guys start ripping out drywall without setting up containment. Spores go airborne, get sucked into the HVAC system, and two weeks later three other suites have mould. A $5,000 problem just became a $50,000 problem.
That’s exactly why containment matters, and it’s where Impact Restore starts every mould remediation Brampton project. Their AMRT-certified crews set up negative air pressure barriers, deploy HEPA air scrubbers, and seal off affected areas before touching anything. The goal is zero cross-contamination to occupied spaces, which is especially critical in multi-tenant buildings where you can’t just shut the whole place down.
If you want to understand why this matters so much, there’s a good breakdown from Scientific Mold Inspection on why disaster cleanup can spread mold spores if done too fast. It’s the exact kind of mistake that proper commercial-grade protocols are designed to prevent.
Their process goes deeper than just scrubbing surfaces. They trace the moisture source – whether it’s a roof leak, pipe failure, condensation, or ventilation problem – and fix it before starting remediation. After removal, they run clearance testing to verify the space meets acceptable air quality standards. A lot of commercial mold removal companies skip that verification step. Impact Restore doesn’t.
They coordinate around tenant schedules and business hours, handle the compliance documentation for workplace safety, and manage insurance claims from assessment through final sign-off. Commercial and industrial properties only.

2. Canada’s Restoration Services
Best for: Free Inspections and Established GTA Presence
Canada’s Restoration Services has been operating in Brampton and across the GTA for over a decade. IICRC certified, and they offer free visible mould inspections, which is a nice touch – it lets you understand the scope before committing to anything.
Their remediation follows the standard protocol: containment, HEPA vacuuming, air scrubbing, material removal, antimicrobial treatment, and post-remediation verification. They can bring in third-party environmental consultants for air quality testing when objective, independent results are needed.
Good experience with insurance claims, and they handle both residential and commercial work.

3. MoldTech
Best for: Mould Specialists with Two Decades of Focus
MoldTech has been doing mould remediation since 2002, back when dedicated mould companies barely existed in the GTA. They were one of the first, and they’ve stuck with it – mould inspection and remediation is all they do.
That specialization shows. Their inspectors have a minimum of two years of hands-on remediation experience (not just inspection experience), so they actually know what they’re looking at during an assessment. They’ve handled commercial projects exceeding 25,000 square feet, and they offer free consultations.
If you want a company where mould isn’t a side service – it’s the entire business – MoldTech is a solid pick.

4. PuroClean of Brampton
Best for: Franchise Reliability with a Local Office
PuroClean’s Brampton franchise offers mould removal, remediation, cleaning, sanitization, and deodorization. They use HEPA filtration for airborne spores, HEPA vacuuming on surfaces, and antimicrobial treatments.
What I appreciate about their approach is the emphasis on fixing the moisture source, not just removing the visible mould. Remediation without solving the underlying moisture problem is basically temporary – the mould comes back. PuroClean makes moisture resolution part of their standard process.
National training standards plus local ownership. A practical combination.

5. Inch by Inch Inspections
Best for: Thorough Assessment Before You Commit
Inch by Inch has over 20 years in the remediation space and meets or exceeds both InterNACHI and IICRC standards. Their inspection process uses moisture meters, thermal imaging, and visual assessment to find both visible and hidden growth.
Pricing is transparent – remediation typically runs $4 to $6 per square foot depending on scope, and initial inspections are free. They provide clear documentation and reporting at every stage.
If you’re not sure how bad the problem is and want a detailed assessment before you commit to a remediation contract, Inch by Inch is a good place to start.

6. Kleen Condition
Best for: Combined Mould and Asbestos Services
Kleen Condition operates out of 8550 Torbram Road in Brampton, so they’ve got a genuine local presence. They do both commercial mould remediation and commercial asbestos abatement – handy for older Brampton commercial properties where both problems can exist simultaneously.
They provide mould remediation certificates on completion, which is useful for compliance, lease agreements, and property sales. Their services extend to residential and construction projects as well.
If your building is old enough that asbestos might be lurking alongside the mould, Kleen Condition can handle both under one contract.

A Few Things Brampton Property Owners Should Know About Mould
Commercial mould problems are a different animal than residential ones. A few key points:
In a commercial building, mould can spread through HVAC systems to areas far from the original growth. That’s why containment during remediation is non-negotiable. If your remediation company isn’t setting up negative air pressure and HEPA scrubbing, find one that will.
Not all mould is visible. It grows behind drywall, above ceiling tiles, inside wall cavities. Musty odours and unexplained allergic reactions among building occupants are often the first signs.
Addressing the moisture source is at least as important as removing the mould. If you don’t fix the leak, the condensation issue, or the ventilation problem that created the conditions for growth, you’ll be paying for remediation again in six months.
And the cost only goes up the longer you wait. Early intervention limits scope, reduces disruption, and costs a fraction of what a full-blown remediation project runs. If something doesn’t look or smell right, get someone in to assess it. Sooner is always better.
