Case Study: Home Mold Remediation in Toronto


The picture above was from a home mold remediation project. It was found in a bathroom, and was not visible to the naked eye. Luckily our client had suspected it of water penetration and decided to give us a call to take a closer look.

We sent our team over a performed a free mold inspection. We diagnosed the problem and confirmed that the client, was in fact 100% right.

Not only was she right, but we also found more areas of molding than they had originally suspected. Fortunately, we were on site and were able to remove the mold and affected materials using a recommended type II procedure. If you are removing more than 10Sq/ Ft, I strongly recommend using a mold remediation contractor for in home mold removal.

The mold spores we deal with on a day-to-day basis are smaller than 10 microns, which is impossible to see with the naked eye. In the old days they use to burn the houses down, because they really didn’t know what to do. Then they moved on to cleaning it with bleach, however it kept coming back. After some serious research, today we know bleach does not kill them, just discolours them. We are now smarter and have better tools to eliminate and correct the problem permanently.

If you suspect anything like this in your home, call a mold remediation company right away to ensure that the home mold removal is corrected once for all.

How can we distinguish good contractors from bad ones?

Great question. There are indeed a lot of bad contractors out there, with little experience (we have over 24 years of experience). A quick way to separate the good from the bad is to ask them this:

What are the minimum pascals for a negative pressure machine with regards to home mold removal?

Answer: Provide a minimum negative pressure of 5 pascals (0.02 inches of water column) and a minimum of four air changes per hour.

If they don’t know that, thank them and walk away; it is one of the main questions on a mold course and every certified contractor will know this.

Home Mold Removal works as follows:

  1. Set up a containment area with 6ml plastic to avoid contamination to other areas.
  2. Install a negative machine with ducting exhausting out through a window with a minimum of 5 Pascals and 4 exchanges per hour.
  3. Use personal protection equipment (and yes I mean respirators, suit, boots etc.), spraying contaminated areas with anti- microbial before removal to minimize spore contamination.
  4. Remove all affected materials and bag them into a dirty area.
  5. Double bag and HEPA vacuum before bringing into clean area to allow disposal.
  6. Using a HEPA DOP tested vacuum, vacuum all areas and surfaces followed by a wet wiping with anti- microbial. Then HEPA vaccum again.
  7. Depending on the home mold removal we also protect with an anti- microbial coating all exposed surfaces to ensure no mold will ever grow.
  8. Always follow by additional hepa air scrubbing (cleaning the air) upon all procedures were completed for at least 48hrs.

There is a lot more details to follow but hopefully this gives you an idea of the process. We would really recommend however that you call a group of experienced and certified professionals who are both meticulous and experienced in mold removal.

As you now know, it takes specialized equipment, procedure and trained specialized workers to ensure the success with home mold removal.

A Final thought
If your apple is moldy do you clean it with a mold cleaner and eat it?
Buyers beware – porous materials must be removed not cleaned, there are options to reduce costs but ask the experts.
