Thread: Mold question

Hello everyone...
I was wondering if anyone can tell me what I am seeing on the surface of mainly floor and roof trusses, along with dead wood and header material. Looks like some organic matter to me???
Thanks,

Linda,

Looks like there is more than one thing going on there. Could be mildew, could be a wood-destroying fungus, could be mold, could be one or more. Difficult to say from these pics.

I would get a pest inspector out to take a look and make any needed corrections or treatment.

Is this a new house? It looks like the OS board was made in April of this year? If it is new I would say the materials got wet during construction.

Thanks a bunch... This is a new home, still under construction as you can see. I have found about 30 homes between 4 neighborhoods in the same condition. Some worse than others. I have reported it, now I am waiting for direction on remediation.

Thanks for all the feed back. This actually turned into a mold issue. The units have been properly treated and incapsulated to prevent future growth. All were tested by a professional testing company with high water contents.
Merry Christmas everyone!!!

What was the cause of the conditions that led to the mold growth? Was that corrected as well?

That type of black stain on new construction is normal in my area for a house built in rainy weather, or from lumber that has been left out in the rain. As long as the wood gets a chance to dry out, it doesn't amount to anything, can't survive without moisture.
I don't even mention it if the house is finished and dry. It is harmless. JMO

Oh I wouldn't say that it is harmless. The mold spores are still present and many people can be quite susceptible to them. Plus, when the owner sells the home the stains are going to become an issue again and he may be asked to correct it at that time.

Looks like you have gotten the mold taken care of. Was the cause of the mold taken care of.

OK, I need to clarify what I said above. Black stain on lumber is not unusual and if the attic is dry, it is not an issue to worry about. If people are mould-sensitive, any damp space will be bad for them. The spores of umpteen varieties of mould are everywhere.

I am posting a few pics here to illustrate what I mean. the first pic is the harmless sap stain on lumber. No problem.
The other pics are from attics where I called for action - moist attics with active mould growth.

The last pic is an example of a wood-destroying fungus on shiplap. It began to grow in a wet stack of lumber and is now dry and dormant. If moisture enters this attic, it will probably come back to life and kill somebody. Be careful up there.

Bruce,

It was due to materials being stored improperly prior to delivery and being exposed to the elements for to long because of lack of roof coverage. No felt, shingles etc...
They used a Dsinfx professional Mold Remediator first, then applied Protex Frame Protection. That prevents against fungal (mold and mildew), bacterial and algae growth and re-growth.
