The TruSoft™ Cellulose Insulation we installed for this homeowner has a higher rated R-Value per inch versus fiberglass. The R-Value is a measurement of the ability to resist heat flow. Using this blown-in cellulose insulation you can have less inches and space taken for a better R-Value than fiberglass.
Mold was found in the attic due to blocked ventilation. We had to treat the mold for sure, but we didn't ever want it to come back so we added 52 brand new baffles to ensure air flow.
This wood came out looking brand new, as if it had been replaced! We spray treated with RMR-86 and almost like magic, we were able to remediate this mold and take care of all the staining too.
Our customer reached out after noticing the sheathing, or underside of their roof, was stained and damp. TCI came in, remediated the start of mold (this situation was caught in the nick of time!) and then we proceeded to rid the attic of the contaminated insulation, air sealed the attic floor as well as around gable bath fan ducts. We finished off with TruSoft™ blown-in cellulose insulation to up the R-Value to 60.
Your attic needs to 'breathe'. Sounds a little funny but it's true! There should be air coming in and air going out, passively controlled by ventilation. While there are different types of ventilation, they need to be installed correctly and working appropriately for the amount of space you have. In this 'before' photo you can see that the insulation is pushed all the way up against the wood sheathing (the underside of your roof) and there are no baffles in place. This is preventing air from flowing upwards and through the soffits (a type of intake ventilation) into the attic and out which can lead to moisture, which WILL lead to mold. In our 'after' photo, you can see that the insulation is pulled back the slightest bit and a baffle (imagine a snorkel) is placed to allow airflow, it creates a snorkel, or chute for air to come in. We treated the mold and the underlying cause so it doesn't return!
