Liam SmithIf there’s one thing Ottawa homeowners can all agree on, it’s that nobody wants mould crashing the party at their place. Seriously, it’s like that one guest who overstays—except instead of eating all the snacks, it’s ruining your walls and health.
Now, here’s the deal: mould removal isn’t exactly the type of task you want to tackle with a scrub brush and some DIY gusto—it’s a real health hazard! Trust me, it takes the right tools and a whole lot of know-how to boot that pesky fungus for good.
So, to save you the hassle (and the headache), we’ve scoured Ottawa for the absolute best mould removal experts in town! Ready for the inside scoop? Let’s dive in!
How much does a mould removal service cost in Ottawa?
In Ottawa, professional mould removal services typically range from $500 to $6,000, depending on the size of the affected area and the severity of the mould infestation. For minor infestations, costs can start as low as $500, while larger, complex cases may exceed $6,000 for extensive remediation.
1. Mold Busters Ottawa
Address: Serving Ottawa and nearby areas
Phone: +1 613 262 3242
Business Hours:
- Open 24 hours
Mould Busters was an easy choice for us when it came to dealing with mould issues—partly because they really seem to know their stuff and take the stress out of the whole process.
Their team is fully certified with the big names like IICRC and the National Association of Mould Professionals, so you know you’re in good hands.
What we loved was how advanced their tools are—infrared cameras and moisture meters that spot problems you wouldn’t even notice.
They’re also big on convenience, since they offer same-day service. They even offer virtual inspections to start things off quickly if you’re short on time—and financing options!
Their Environmental Care Club was another plus! It’s an annual membership with structured checks and some solid extra benefits.
Of course, not everything’s perfect. A few delays popped up after the inspection stage, which was slightly frustrating. However, we can’t help but commend them for being upfront about costs and offering a Price-Match Guarantee!
Responsive team and outstanding results
“What a great experience! The sales team were easy to deal with and very responsive, and the remediation team showed up exactly on time and got right to work. They did an incredible job, making my wife and I feel great about moving into our new home. The before and after pictures were amazing! We would not hesitate to use them again if needed, and will gladly recommend them to others.”

Fair pricing with impressive attention to detail
“I hired Mold Busters to clean some mold from my attic sheathing. Everyone, from the supervisor Wesley to the technicians who did the clean up, was friendly, professional and efficient. I got quotes from a few different companies for the remediation, so I can confidently say that their pricing is fair and they provide excellent value for the quality of work provided. At the end of the service they sent me a detailed report with before and after photos and I was honestly stunned at the results. My attic is immaculate now and it was worth every penny!”

2. First Response Cleaning
Address: 2710 Lancaster Rd #103
Phone: +1 613 979 2795
Business Hours:
- Open 24 hours
First Response Cleaning was an easy pick when one of my team members needed help with mould removal—it’s one of those companies locals seem to recommend a lot!
They deal with pretty much any kind of mould problem, whether it’s from moisture, flooding, or those annoying leaks that just won’t quit. What’s cool is that they’re super quick on their feet.
You can book a same-day inspection, and no matter how busy they are, they’ll somehow fit you in. When my team called, they checked out the place the same day and came back the next day ready to fix everything.
Oh, and they’re all about safe cleaning methods, so you don’t have to stress about harsh chemicals hanging around after they leave.
They also have this option to rent professional cleaning gear—things like air movers and scrubbers—which is handy if you’re into doing extra clean-up yourself.
On the flip side, a few people told me their phone staff can be kind of rude.
Exceptional cleaning and thorough preparation
“Ryan, Jamie and Adam were superb. Not only did they show up on time for the estimate, they did also showed up as-promised despite the heat in the attic. They were extremely polite and friendly and could not have been more respectful – even isolating/prepping and cleaning throughout the job. Highly recommended!!!”

Outstanding service and customer prioritization
“Bob and his team did an incredible job with mold removal and clean-up in my basement. From the moment a made the first call to the day the job was done I felt like a priority. I can’t say enough good things.”

3. Ecoclean Construction
Address: 2100 Scott St #207
Phone: +1 613 406 1426
Business Hours:
- Open 24 hours
Ecoclean Construction was one of those companies we trusted, partly because of their focus on eco-friendly practices. It’s not just about mould removal with them; these guys take it up a notch by specializing in eco-friendly construction.
They use innovative materials and methods that minimize environmental impact. When we spoke to their team, we could tell right away they’re super skilled at what they do.
The best part? They don’t just fix the issue—they teach you how to prevent mould from coming back!
They don’t stop at mould removal either. They cover a ton, from residential and commercial construction to renovations and even green building consultations.
Their attention to detail is excellent, and some of their customers also said the same.
However, one downside is the lack of after-service communication—it’s a busy company, so follow-up can be a hit or miss.
Prompt response and honest professionalism
“I recently experienced a persistent mold odor in my home and reached out to EcoClean for assistance. Robbie responded quickly and arrived the very next day. He quickly identified that the source of the smell was coming from a neighboring unit, not within my own space. He treated my home with a specialized spray to help neutralize the odor, which was highly effective. I was very impressed with his professionalism, punctuality, and honesty throughout the entire process. I would confidently recommend EcoClean to anyone in need of reliable and efficient mold-related services.”
Dayna Gregoire, Google Review
Clear communication and efficient execution
“Nick was exceptional! His initial visit for our basement project was concise, clear, and practical. He provided a well-defined scope of work, quickly scheduled our appointment, and completed the job efficiently and on time. His accurate diagnosis of the issue was straightforward, without any hype or overcomplication. Honestly, skip the hassle of calling others (we will for sure in future)—reach out to Nick and his team, who are undoubtedly just as skilled and great to work with!”

Green Property Restorations is made up of IIRC-certified professionals, and their 20+ years of combined expertise really show in their seamless approach to restoration.
One of the highlights of their service is their comprehensive mould remediation process—this includes anti-microbial abatement, inspections, air purifying processes, and even free assessments.
We’re able to tag along with one of their services, and from what we’ve seen, the team is punctual and incredibly thorough in inspecting the property and presenting a tailored treatment plan.
They don’t rush through the process, and their transparency about costs and timelines reassures clients that they’re in good hands and won’t encounter surprise charges later on.
Some of their previous clients we spoke to mentioned how easy it was to work with their staff throughout the process, and we can’t help but agree with them!
If only Green Property Restorations had quickly responded to our inquiry, the entire process would have been perfect!
Highly efficient and honest service
“This company is the best ever. I would highly recommend them. They are efficient, honest and do an excellent job. If I could give them a 10 star I would. They also respond to any issues very quickly.”

5. SERVPRO of Ottawa, Vanier
Address: 1200 Rainbow St, Gloucester
Phone: +1 613 742 8222
Business Hours:
- Open 24 hours
SERVPRO has been in the game since 1967, with over 2.260 franchises out there, so it felt like we were turning to people who really know their stuff—and it shows! These guys cover everything, not just mould, but also storm, fire, and water damage.
And the best part? They don’t just swoop in and leave after cleaning; they handle everything from inspecting the damage to sealing it up and even full-on reconstruction if needed.
What stood out the most was the equipment they used. They had these HEPA vacuums and air scrubbers that honestly felt fancy—like, next-level stuff you don’t expect.
Plus, they focus on keeping the air quality good while cleaning, which was a huge relief knowing our space wasn’t just clean but also healthier.
The team’s members are certified through the IICRC, showcasing their expertise, which really came through in how professional and thorough they’ve been during the entire process. That said, availability can sometimes be an issue because of high demand.
Quick and affordable mould remediation
“It was a great experience with Servpro. We had mold problem in our house. They came in for a free inspection and provided a swift remediation of the problem at very good price. Would highly recommend Servpro and we’ll be calling them again if we ever have similar problems.”
