What Does Mold Look Like? Ask a Vancouver Mold Specialist

http://www.fairbairninspections.com  604-395-2795 Hi it’s Mark Bossert from Top Local Lead Generation. We’re here with David Fairbairn of FairbairnInspections.com in Vancouver and you can reach him at 604-395-2795. Today we’re talking about the gross stuff, we’re talking about mold. So how’re you doing today David? David: I’m doing pretty good Mark. Mold’s not that gross - if you like blue cheese or if you like beer mold is pretty good. Penicillin if you like not getting sick. Mold is pretty helpful. It is gross and in some cases pretty helpful. I’d like to show you today what mold looks like - have you seen a lot of mold? Mark: Unfortunately, I have. David: Excellent, okay so I’ve got some photos for you. We’re talking about what mold looks like. So this is probably one of my top questions when it comes to mold related questions - somebody is standing there looking at something and going I think that might be mold, I can’t tell. What I want to start with is that it’s very important to note you can’t tell if something is mold or not just by looking at it. You can know what mold usually looks like and you can know different growth patterns, but if you’re not sure, you should sample it. Take a sample of the material and take it to a lab for testing because they’re actually going to be able to tell you if it’s mold or not. Even myself, doing mold for years, I’ve done testing and sampling and investigations and there’s still some cases where we find mold where it doesn’t look like mold or it doesn’t look like anything. What I’d like to do is show you how mold grows and this will give you a better idea about how it appears and what it might look like. So what we’re looking at now is a microscope slide of some mold. What we’ve got here is the structure of mold and you can see that it’s not just a blob of slime, it’s actually quite defined and that’s because mold is a plant. It’s part of the fungus family, so when you have mold you actually have fungus. Mushrooms, those are fungus. There’s different types of fungus and mold is a type of that. So it grows like any plant and when you look at it up close, you will notice that it has branches just like a tree or a plant and you’ve got the tips where you have the spore production (the circles). So if we look at what that actually is we’re looking at is called Mycelium. Mycelium is the structure of the mold - it’s in all the branches woven together. The branches are called Hyphae or Hypha individually. So this is how it spreads and grows and once mold sets up, it takes about 24-48 hours to grow in material and after a certain amount of time usually 10-14 days it’s ready to reproduce. So the mold decides to release some spores into the air and hopefully those spores settle and grow more mold. So when you hear about respiratory problems, people getting sick from mold, it’s the spores we’re talking about, it’s not the actual mold material, it’s actually the spores that are floating around in the air and you’re breathing them in because some spores are toxic. So that’s the idea behind the growth. If we look at it here, it’s eating away at this bread - you’ve probably seen bread mold before, it usually doesn’t look this extreme, but this is just for illustration. We can see that the mold here has taken root, it’s feeding off the material, mold will grow in any organic material if the conditions are right. If it’s warm and wet it usually thrives and at one point or another we get spore production and this one is actually in full spore production mode. So we’re looking at an attic now Mark, this is a fairly new construction building, this house is only… do you want to guess how old this attic is? Mark: From the state of the OSB and some of the other clues I can see there, probably no more than 10 years old David: Yeah, it’s actually 1 1/2 years old. So just as an aside, we perform home inspections, you should always get even if your house is a year and a half old. Get it inspected every single time. So this attic a year and a half old, terrible ventilation problems and they’re also using OSB which stands for oriented strand board, which has basically replaced plywood in most new construction and you can see that it’s made out of wood chips. It’s also a great surface for mold to grow on. I would conservatively say it’s about 150% more likely to grow mold than plywood or wood itself
