  1. Just to be clear on Gary's comments: It is not my opinion that home inspectors SHOULD be inspecting for mold. It is my opinion that a home inspector, if s/he WANTS to inspect for mold, will do a better job than some other highly-specialized "experts" who don't understand how buildings work. Also I expect home inspectors to be more ethical, not selling scare, or un-needed tests and services. By contrast there are plenty of "turnkey" mold companies who do it all - testing (no real inspecting), cleaning, and then post-remediation clearance testing - the fox watching the hen house so t
  2. Well Gary thanks for the debate on what I, Dan Friedman, call myself (other than expletives) I would say that I offer mold inspection and testing services, but I am hardly a "mold inspector" in that no decent inspector simply goes into a building looking at or for only one IAQ problem source (if that's the topic). Haven't many of you fellows found cases where a client is in a panic about a trivial amount of mold, nothing deserving professional analysis or cleanup, but you see that the gas fired heater flue is dumping flue gases into the living space or some other much more serious conc
  3. In reply to the writer who points out that I list myself as someone to hire to investigate mold problems, Of course I list myself - I'm serous and trained - faculty at the Harvard School of Public Health, McCrone institute of microscopy in Chicago, various PAAA spore camp seminars etc. Frankly I think that a home inspector trained in mold and mycology makes a better mold investigator than most industrial hygienists (who don't know much building science). Pete is also very well qualified and we've enjoyed some classes together. ANY qualified inspector with training and exprie
  4. That should read, "I couldn'tid="maroon"> care less..." Very common slip. Thanks to Gary Randolph for referring readers to my mold information website - its home page is www.inspect-ny.com/sickhouse.htm I agree that it's difficult to read and believe various credentials offered to and by "mold inspectors" - there are some (I list one at my bio as an example at www.inspect-ny.com/danbio.htm) that you can obtain by just sending money, others for a weekend class. A combination of these things in an inspector's background may be useful in choosing an inspector: - experience
  5. Regarding Originally posted by mridgeelk "I found these Zinsco panels in a commercial setting today. They are 60+/- years. Are Zinsco panels of this vintage problematic/unsafe as the more recent versions?" Reply from Daniel Friedman: Zinsco panels or "Zinsco-Sylvania" models have bus arcing problems and can fail to trip - a latent safety hazard. We do not have as big a data base of field reports nor independent research on this item as we do on FPE Stab-Loks or some other hazards, but Zinsco Panel Hazards are discussed in depth at http://www.inspect-ny.com/electric/Zinsco.h
  6. I thought I'd start a separate thread about this FPE Stab-Lok issue and explain some of the more technical aspects. THE FPE Stab-Lok HAZARD The hazards of Federal Pacific Electric FPE Stab-Lok panels have been studied and documented thoroughly, have been the subject of national home inspection seminars and conferences, published in newsletters, and published in the Journal of Light Construction. Basically we have circuit breakers that fail to trip at a rate thousands of times worse than normal industry standards, a bus that can fail to retain the circuit breakers, and possibly other defec
  7. I've been inspecting and testing septic systems for about 30 years. Early on I found that there was no common guideline on just what to do and what to report, so I've made a project out of figgering out what we need to do, including reviewing laws, texts, and course material. I have an ongoing project website on the inspection, diagnosis, maintenance, and repair of septic systems at: http://www.inspect-ny.com/septbook.htm Since questions and critique make the data more accurate and more complete, I welcome questions from inspectors about septic systems, and I especially appreciat
  8. For a long time I've been collecting photos and text on how to evaluate foundation cracks and movement. The current project is at http://www.inspect-ny.com/structure/foundation.htm and it's rather extensive across most foundation types and types of damage. I'd much welcome comments, critique, content suggestions, or questions about the content, and I'm hopeful that some of the material may assist readers in this forum with diagnosing foundation problems. My summary opinion about attacking foundation questions is to ask a basic question or two: What is the apparent (for no
