Welcome to JonEakes.com. I hope you found the special series on Hidden Dangers in your home interesting. Unfortunately in a few short minutes on TV I cannot say much, so here are links to more detailed information on each of these topics that you saw on TV. A thanks to CarsonDunlop, home inspectors in the GTA, for finding me the right houses to show you these problems: CarsonDunlop.com.
Click here on RADON for more information. In the first article in the list that pops up you will find good general information and a hot link to a free download book from CMHC about Radon. In other entries you will see the Dranjer, a very effective dry floor trap specifically designed to stop radon from coming through your basement floor drains and sump pump pits.
HIGH POWERED KITCHEN FANS
Although backdrafting of chimneys by powerful exhaust fans can potentially kill you through carbon monoxide poisoning, for most of us it is a moderate pollution problem, which means it never shows up in medical records. In my experience I have found that it can be responsible for everything from strange odours in the house to nausea and flue like feelings that seemed to have no cause -- part of the sick building syndrome. I remember one interesting house where two smokers always smoked under the range hood when it was cold outside to keep from polluting the house, but in fact they were drawing musty attic air into the bedroom through the ceiling recessed lights. One lady living in a basement apartment, next to the furnace room, was constantly going to her doctor for strange flue like symptoms, until she heard one of my radio shows and stopped using her kitchen fan until a combustion air duct was installed next to the furnace. In both cases, once they understood what was happening, they were able to solve the problem.For a lot more information, click here on High Power Fans, which includes a link to download the summary of the National Research Council's research report.

SHOWER TILES AND GROUT ARE NOT WATERPROOF
I don't know how many times I have had people tell me that the grout and caulking in their shower was perfect, there were no plumbing leaks and they still had either water spots on the ceiling below or tiles popping off the wall with mold behind. It wasn't until the guys at Schluter Systems taught me the building science about how much moisture actually does go through the grout in the form or vapour, not mentioning any cracks, that I came to understand the real need for a waterproof membrane right behind the tiles. Even concrete boards can hold a lot of water and although they won't rot, that stored water can cause problems. The real beauty of the system we showed on the TV show was that it allows the tiles to be adhered directly to the waterproofing layer with non-organic, inert thin-set mortar which will not support mould growth.
