Inspected a house yesterday and found this where the return air was in the wall. No elevated moisture located, is this mold or dust?

Vendor e-mail

NACHI - Sat, 06/29/2013 - 21:03
Got this unsolicited e-mail the other day:

"Dear Mr Decker,

Here at EMFADR we have developed a paint for the building industry that will neutralise the harmful exposure to the low frequency electromagnetic fields found in everyday living including homes, offices, schools, hospitals etc.

Our combating Electromagnetic Field “ADR” technology differs from the conventional electromagnetic field shields (which are based on conductive media and need grounding) because it is unique in its make-up and will only block the low frequency EMF radiation and this allows for the body and the earths own natural magnetic fields to still function. The ADR solutions are the first of its kind, both ground breaking and award winning in several countries across the world.

The ADR paint (ADR SOL) will be used in the construction of (please visit this link: http://wolnemiasto.pl/en/index.php ) a new 1,200 strong apartment community complex here is Poland. If I may, I’d like to discuss the possibilities of our ADR SOL product in a mutual business relationship with yourself.


Kind regards,"

I responded to him that:

1) His e-mail was unsolicited spam. Been getting a lot of that, recently.
2) That low frequency EMF is not harmful. The EMF fields that the general public comes into contact with can not cause harm. So much for the scares about living too close to transformers or getting cancer from cell phones.
3) This paint, most probably, doesn't work, unless it has a very high conductive metal content and is grounded.

I recieved back a response "You have got to be kidding me.".

I then responded that I was a trained Radiation Safety Officer for a major University and I was not kidding.

Have not hear back from him yet.

Any other scams out there that are soliciting Home Inspectors?

Service disconnecting means requirements, Illinois electrical code?

NACHI - Sat, 06/29/2013 - 20:05
The seller of a house I inspected this week called, with my clients permission, to inform me the city inspector told them they had to Replace the service panel because it did not have a Single breaker/disconnect to shut-off all electricity.

The inspector, in writing, said that according to Illinois electrical code the electrical service in a home requires the system to have One breaker/disconnect to shut-off all power in the home.

First, I'm not aware of any State of Illinois electrical code. Second the code this city goes by is the 2011 NEC, as posted on their website.

So is anyone aware of any "updated" code requirements of service disconnecting means at a single family dwelling that limit it to no more than One means of disconnect?

Or is no more than six disconnects for each service still the rule?

By the way the power at this 100 amp FP panel could be shut-off with four throws.

Did I break it? ...Heat pump

NACHI - Sat, 06/29/2013 - 17:47
Was testing a heat pump on the cooling cycle today on an older home. There was no manufacturer's plate on the unit but I would guess it was at least 15 to 20 years old. It looked like a Nordyne unit

This is a vacant house that has been vacant for about a year

I let the cooling run for about 30 minutes or more. I decided to shut down the cooling and test the emergency heat....I turned the thermostat to the "off" position... A few seconds later I turned the thermostat to the "Emergency" setting from the "Normal" setting on this older thermostat...then I turned the thermostat from "off" to "heat"....and turned the thermostat up over 80 degrees....

Buyer was outside and says he heard a muffled sound like a muffled backfire....Unit stopped working and would not re-start.....Did I break this unit?

interperting infrared images

NACHI - Sat, 06/29/2013 - 16:41
I'm curious if anyone see a difference between batt insulation and icynene insulation when installed in the wall cavity at the floor and ceiling. Normally I see a thin brighter image along the baseboard/floor and at the wall/ceiling point with it hot outside and cool inside with batt insulation. Wondering if anyone seeing the same thing when icynene is used or does it seal better.

Electrical Code Question from Ontario

Not sure if I posted correctly, so here's a second attempt:

Home Inspector way...

NACHI - Fri, 06/28/2013 - 14:24
...of taking a sauna :shock:
This attic had no ventilation at all. I popped my head in there and thought I was back in Finland getting ready for a sauna.
Not quite as hot as I like mine (add about 70 degrees F), but just about as humid.
Ah... memories... :D

Sinkholes and armadillos

NACHI - Fri, 06/28/2013 - 11:37
O.k. I got one...A recent tampa home inspection. 1995 home, occupied, very near tampa river trail.

Bad Drainage, condensate line, animal burrow.

Can I keep sinkhole out of this narrative. We have had a deluge of rain recently.

"The foundation has an area where soil erosion is undermining the foundation
Indications include but not limited to

There are cracked kitchen tiles and a minor settlement crack located on the same side wall in the garage, also the kitchen cabinet appears to have dropped a bit. Damage appears to be occurring because of the undermining.

The meter was checked at the end of the inspection with the client. We had a reasonable expectation that the water was not being used, However the dial indicating water flow was spinning. A professional licensed plumber with experience in detecting slab leaks should be consulted before inspection contingency expires.

The inspector was unable to determine the cause of the undermining of the foundation. Possible scenarios include poor drainage, condensate line draining to close to the foundation, Slab leak aka plumbing installed in the slab on grade foundation or my favorite one, Animal burrow (armadillo) with drainage water filling up the undermined area."

Looking forward to the responses...
Tom
