My uncle totally scored when he bought a house downtown for cheap—at least he thought he did. Imagine his dismay when he found out that there was mold and asbestos in the basement and inside the walls.
He asked the family for possible solutions, and I sent him a compilation of the best remediation and environmental cleanup services in the city. Luckily, they were able to remedy the situation quickly, and they didn’t charge a ton either.
If you’re in a similar bind, don’t fret. Here’s the list I gave my uncle, and I hope it’ll help you, too!
How much do remediation & environmental cleanup services cost in Toronto?
How much do remediation & environmental cleanup services cost in Toronto?
Remediation & environmental cleanup services in Toronto may set you back $1,500 to $25,000, depending on the severity and size of the job.
Minor cleanups like mold removal in a small area might start around $1,500 to $5000, while larger projects can easily run into tens of thousands.
Factors like contamination type, property access, testing requirements, and regulatory compliance all affect pricing.
1. Restoration Mate

For over 15 years, Restoration Mate has helped locals handle water damage, mold, and other environmental messes. In fact, their 24/7 emergency response is a lifesaver when things go sideways.
First, they give a free onsite estimate after checking the extent of the damage. Then, they create a customized plan which may include water extraction, drying, mold remediation, deep cleaning, or even full-on restoration.
Once the job’s done, they even perform a thorough cleanup. But I recommend doing a final walkthrough with the team, because we heard about areas of mold that were left untreated.
On the other hand, they’ll handle the insurance side for you by taking care of the paperwork, as well as providing detailed reports and photos.
Professionalism, efficiency, & communication
“I was very impressed with the professionalism, efficiency, and communication of Restoration Mate. I have a large, difficult space for an attic, and they spent extra time and effort with it to remediate the mold. He was also able to check the temperatures of inaccessible parts of the attic to see if it was properly ventilated. They were easy to get a hold of, very knowledgeable, and provided lots of information and proof of mediation. The price was fair for all the work they had to do. I highly recommend them!”

2. AMC Environmental Corporation

AMC Environmental Corporation has over 15 years of experience catering to all kinds of clients, from homeowners to big industrial sites.
They do asbestos and mold removal by the book, following safety regulations, including those set by OSHA, CEPA, and the Ontario Ministry of Labour.
Their process starts with a free estimate of the damage. Afterward, they use HEPA-filtered negative air systems, antimicrobial treatments, and eco-friendly cleaners to make sure the job’s done right.
To cap off the process, they even run air quality tests and hand over official clearance certificates so you have peace of mind (and documentation, too!).
While we heard that their services can be a bit on the pricey side, most of their clients seem happy with the services they provide.
Amazing experience with AMC Environmental Corp
“I had an amazing experience with AMC Environmental Corp. They helped me with asbestos testing, removal, and abatement, and the entire process was seamless from start to finish. The team was incredibly professional, knowledgeable, and respectful of my space. They kept me informed every step of the way and made what could’ve been a stressful situation feel totally manageable. I’d highly recommend AMC to anyone looking for reliable and thorough environmental services. Truly top-notch work.”

3. CleanFirst Restoration

CleanFirst Restoration has been removing mold and asbestos since 1989. Their clients include homeowners, businesses like The Bay and Brookfield Property Management, and even government buildings like Ontario Place.
The process kicks off with a free, no-obligation inspection. A certified specialist will take a look at your space, assess the risk, and give an honest estimate.
After identifying the source, they create a remediation plan to stop it from coming back.
What really impressed me, however, is their lifetime guarantee (and a 10-year guarantee for attic mold removal). Not all remediation companies offer this.
However, I’m not impressed by reports of abrupt appointment cancellations. This is definitely a hassle, especially for those who already planned their days around the visit.
Best customer service and mold remediation
“Michael and his crew provided the best customer service and mold remediation. He was so kind to walk me through the process and answer all my questions. He was very professional and went above and beyond. I would highly recommend his Company, CleanFirst.”

Great quality, on time, on budget, professional
“We were in the process of major home renovations when we discovered we had asbestos in our ceiling and walls. Michael and his team did a fantastic job removing the drywall and cleaning up. I showed it to my project manager, and even though they see this all the time, they were also impressed by how cleanly they did the job. I highly recommend this company. Great quality, on time, on budget, professional, and they were very responsive.”

4. Lemarg Restoration

Ready to respond across North America, Lemarg focuses on restoring homes and businesses after fires, floods, storms, and other environmental messes. And you know what’s amazing? They can be on-site within an hour!
From start to finish, they handle everything: full extraction, hazardous material disposal (asbestos, mold, chemical spills), and complete property restoration. They can also be counted on during emergencies since they’re open and ready to respond 24/7.
As for insurance, they can bill your company directly once the job’s done. Now, if your claim gets denied, they also offer flexible financing options and coverage plans.
The only downside we heard about is that some general managers have been described as rude and pushy. Still, don’t let a few bad apples turn you off—most customers have raved about their services.
Cannot be happier with Lemarg and their team
“I had a very disturbing water-related situation, insurance called their preferred contractor, who happened to be Lemarg Restoration. The manager showed up an hour after I made the call, explained all the related work that needed to be done in detail, walked me through the paperwork process, and coordinated his crew. They work fast, clean, and efficiently. I loved the fact that they protected my main floor hardwood, stairs to the basement to avoid any scratches. After they finished with the emergency process, they shampooed my carpet and made sure to come back when everything was dry to take the final moisture readings. I cannot be happier with Lemarg and their team of professionals. I highly recommend them to everyone.”

Incredible, very responsive, and very professional
“Had a big flood at one of my store locations, and my Insurance company sent in Lemarg to do an inspection and emergency call. They were an absolute pleasure to deal with. Russell, who was sent from Lemarg, has been incredible to work with, very responsive, and very professional. Highly recommend. Will definitely be working with them in the future.”

5. Canada’s Restoration Services

Canada’s Restoration Services has been around for 15 years, and as proof of their reliability, they were named a HomeStars Top Restoration Company from 2012 to 2025.
They handle all the heavy stuff—mold and asbestos testing and removal, as well as full environmental cleanup.
To start, they check the extent of the damage and collect samples for third-party testing.
Once everything’s confirmed, their crew gets rid of the problem using binding agents, poly bags, air scrubbers, and HEPA filtration systems to keep your air and space clean.
What we do love about them is their responsiveness—they’re on call 24/7 and promise to be on-site within 45 minutes for emergencies. Just note that we heard about them ghosting clients, so you might want to confirm your appointments.
Carried out the emergency work efficiently and on time
“During flood devastation, Marat and his highly professional team came as saviours and carried out the emergency work efficiently and on time. In such difficult times Canadian Restoration services team’s assurance and advice were greatly appreciated. Shall always be thankful.”
Suresh Kalidoss, Google Review
Really went above and beyond the scope of work
“We were doing renovations in our home when we found asbestos and mold. We reached out to Canadian Restoration Services regarding the matter, and within a day, we had a project manager contact us. Our project manager, Aris, and his team were very supportive and helpful; they would always answer our calls/ reply to our messages. They did everything they could to help us and really went above and beyond the scope of work.”
