Mold remediation

NACHI - Wed, 07/03/2013 - 10:31
I recently had a mold remediation company come out to scrub the floor joists in my crawl space to remove mold. When I went into the crawl space to see what they had done, I realized they didn't scrub it at all! All they did was fog the crawl space. At that time I noticed that all of the insulation was wet throughout the whole crawl space. When I spoke to the owner of the company he informed me that he would send out another crew to scrub all the floor joists down, he said he would be there to supervise them this time. He told me that they would take the insulation down and scrub the joist, I asked him about the wet insulation and he told me that there was no way that they were responsible for the insulation being wet, he said it was from condensation on one of the pipes. I could possibly see how the insulation might be wet near that pipe but not the whole crawl space.
Two days prior to them coming out, I know for a fact that the insulation was bone dry because I was in there for hours wiping down the joist myself. Can over-application of fogging cause moisture or pooling on the insulation? Any advice would be greatly appreciated, I'm just so frustrated. Thank you.

Thermal imaging … for vehicle engineering?
Fleet Owner (blog)
He explained that thermal imaging is the use of cameras to photograph heat in the environment, with this captured “heat” appearing as an infrared image. Thus in Ford vehicle testing, air leaks show up as “hot spots” or locations where heated air ...

Funny Story

NACHI - Wed, 07/03/2013 - 06:20
At one of the houses I inspected, the Realtor was with the buyer and showing him a couple of last minute things. This is a pretty good set up for me because the distraction helps keep me focused on my work. In this case she was showing him the exterior features of the home and then suddenly started talking about the Christmas lights. She went on and on about how she had worked extra hard at negotiating the lights into the deal and about how expensive they were. Going inside, she turned them on and showed the buyer how they glowed. After awhile the buyer was becoming impatient, stopped her mid-sentence and suddenly burst out, "You know, the Christmas lights are great and all... but I'm Muslim." Nothing more was said about the lights.

Never had this...

NACHI - Wed, 07/03/2013 - 00:06
I typically test the Delta T of the A/C at the return and just past the plenum. Today, I got a difference of 29°F which is way higher than anything I've gotten before.

The unit is 3 years old, outside temp was 75°F, overcast, RH about 40-50%. I let it run for about 20 minutes after running the heat for about 15 before I measured the temp. The temp past the A-coil was 41°F. I'm sure there are many factors to this and I don't look at Delta T as the end-all of indicators, but I figured it's worth discussing.

Is this high of a Delta T a concern? It seems odd to ask this question, but it's just so out of the ordinary.

Can anyone figure out the splicing

So many splices in the panel and some breakers not used. What gives?

Already recommended an electrical contractor to re-evaluate.

Would you recommend a gutter?

NACHI - Tue, 07/02/2013 - 22:56
Even though it's a smaller surface area of the roof, would you recommend a gutter to prevent splash back on the ground. The water is causing some of the wood trim to dry rot because of the peeling paint. The larger areas of the roof all have proper gutters.

Building Permits

NACHI - Tue, 07/02/2013 - 22:20
How does one go about finding out if a building permit was pulled? I’ve been on the states .gov site but no luck a lot of info on how to apply for one. Do I need special access to search/see permits? I recommend to my client to inquire about permits but not sure how easy they are to find.

Exhaust/intake vent under a deck

NACHI - Tue, 07/02/2013 - 21:39
I am looking for documentation on installation location of a vent (combination intake and exhaust) for a furnace under the deck.

I feel the exhaust could very easily be drawn back into the system with this set up.

Any ideas?


While the endless debate goes on....

NACHI - Tue, 07/02/2013 - 20:36
While those scurry and try this and try that on calling this one an idiot and that one a liar. Some of us have been using our time to provide a better service to our clients.

Instead of using all my time trying to discredit others, we endlessly work on our business.

Please all of you keep up the fight and keeping calling everyone and using your time try and "one up" the other is the latest creating finally done!
