If in Doubt, TEST!
There are many times during mold inspections that there can be a difference of opinion, especially during real estate transactions. The seller does not think it's mold and the buyer does or more commonly different inspectors have different opinions. 
What do you do? The answer is easy, you test. Taking lab samples to determine if it mold or not puts science in the drivers seat and takes all opinions out the equation. It is worth the minimal cost of a few lab samples to make sure of the conditions present if there is a dispute over what may or may not be there. Don't be afraid to ask for lab sampling.

Replace the Insulation?
A common question during mold remediation is "Do we have to replace the insulation?". The answer is maybe. 
If you are using a traditional mold remediation technique utilizing Chemical or Biocide base products then YES you must remove the insulation. This includes products like ShockWave, Sporocidin, Microban and others. The IICRC mold remediation standard, if followed properly, requires the removal of insulation to successfully remediate the area.
If you are using an Enzyme mold remediation product then most likely you do not have to remove the insulation which is a major cost savings. 
Why the difference?  Chemical products do not treat all surfaces and can not penetrate the insulation to successfully treat all of the infected materials. They are surfacants and only treat the physical surface the touch. They do not remove the root structure of mold spores therefore only have minimal success when treating insulation. Enzyme products are living micro organisms that, if applied properly, can penetrate through the insulation and treat all surfaces. Additionally, the enzyme catalyzes (breaks down) the mold spores including the root structure.
It is important to note that insulation can also be compromised by pest infiltration and require removal for air quality reasons. It does not matter what process you use in these cases as it just has to go. 
Note - Lab testing is a must to determine that the remediation was successful. 
 A little insulation for tomorrows job!

A Little Before & After

Carver - Feb 18

Rain on top of Snow - WARNING

So for the last few weeks New England has been hit with EXTREME cold temperatures on top of one good sized snow storm. This is being followed by a very quick thaw and then a large amount of rain. This combination creates a huge potential flooding hazard to home owners!

The extreme cold has caused the ground to be come very hard with little to no place for water drainage. The recent snow has piled up against the homes and around basement window wells. Now the melting has begun which is compacting the snow down even further. With the rain coming in tomorrow, expected to be more than 2"+ inches of water in some places, this water has no place to go but into the homes. 

The biggest danger is around basement window wells that have already piled up with snow. The water will overflow the already full window well and enter potentially causing serious water damage or lead to eventual mold growth. 

It is important to take a few minutes and shovel an area out around the entry points to allow for the coming rains to drain away from the home. A minimum of 3 feet all around is recommended. Also check you sump pumps to make sure they are working in case water does enter the home. 

We really want to avoid this.......

Is this a Mold Problem?

Not an easy question but this picture actually tells us a lot about the conditions present in this attic cavity. 

- The newer piece of roof sheathing was installed 10 years ago during a roof repair. The other sheathing in the area is 20+ years old. 
- This attic had a previous venting problem that resulted in substantial moisture staining and mold growth on the roof sheathing.
- The attic ventilation has been corrected/repaired when the roof was repaired 10 years ago.
- The current attic ventilation is functioning properly.
- There is no evidence of ongoing or viable mold growth.
- There is no evidence of excessive moisture or condensation present in the attic.
- There is evidence of previous mold growth on the old sheathing. Note - mold can go dormant for many years awaiting conditions to be right to continue growing.

So what needs to be done? Again, not an easy question, there is evidence of previous mold growth and if the right conditions become available it can continue to grow but as of the time of inspection this is more of a cosmetic condition (and has been for almost 10 years). 

Generally with this much moisture staining and previous mold growth on the older surfaces it is much safer to have it removed and reduce the potential for future mold growth. It really comes down to a personal and emotional decision.

Frost on the Roof

Well, the cold weather is here whether we like it or not. Now is the time were we can really see the amount of moisture entering our attics with condensation being very visible. Many attics with moisture issues will begin should signs of frost on the roof or ice on the nails. This is a "Red Flag" that the ventilation is either not functioning or there is moisture entering the attic somewhere. This does not mean you have a mold problem but if left unchecked can lead to mold or other damage in the attic.

Eliot: We had mold that had been caused by a bathroom fan being vented in the attic. We needed to treat the attic mold ASAP due to a pending real-estate transaction. Indoor Environmental quickly came and assessed the situation, treated the mold, and confirmed the mold was treated (air test) with very fast turn-around.
