Had a one time leak that cause mould we didn't know about until we ripped up carpet for new flooring installation. Called Ontario Mould Specialists and they sent a crew out within a couple of days of calling.

Crew was efficient and professional. They took care to lay down tarps as to not track snow and dirt inside. Explained the entire process to me as they were getting rid of the mould.

Cleaned up the room in question after they taped and mudded the new drywall.

Nothing but good to say about this company and their crew.

I was very pleased from start to finish. The estimate was done in a timely manner and the work was completed quickly and efficiently . Both office staff and working team were friendly and accommodating. I would certainly recommend this company for mould remediation and peace of mind!
Thank You! ☺️

They are very personable and they do good work. The only thing is, I can't feel any difference in my allergies so I don't know how effective the procedure was

Very good job by professional company. Worked quickly and efficiently . Completed all work as quoted and were very accommodating to my needs

The guys did a great job remediating the mold in the attic.
In addition: they installed a insulated exhaust fan hose, installed and secured multiple moore vents, and levelled the insulation for uniform coverage. They were pleasant and did great work.

Easy to schedule the appointment. Very nice customer services. Quick response. Quick to get the lab result.

Needed Mould removed and treatment in attic from improperly vented bathroom fan into attic. Chris came without delay and provided estimate. Patty booked our appointment.
The crew came and completed the job with no mess left behind.
I checked the work in the attic - it looked as good as new. There was NO residual odor. We are very satisfied.

They did good work. Showed up on time. However the mold returned weeks later. They were great in handling the situation promptly. They came back and re sprayed. Hopefully this time it will do the trick Also I thought the price was a little high for one day’s work

We discovered mould along the basement wall of a rental home of ours
Ontario Mould Specialists came to the home and assessed the project shorty after we called them. Within a week they came to the home and completely eliminated the problem. They left the job sight spotless. Very professional, I would highly recommend this company.

Lost most of the roof in a late fall storm. Turned out, that while doing the roof found the attic full of mold. These guys came right away, within 4 days, took out all of the old insulation, treated the whole attic getting rid of the mold. Sprayed something to ensure the mold does not come back and then re-insulated the whole attic. Done, no fuss, no mess in two days. The best guys to deal with.
