I have been getting my code info from: http://public.resource.org/bsc.ca.gov/ However, I can't seem to find the maintenance code. Does anyone have a link where this can be found? Thank you, Larry Hoytt Marin County, CA

We have all seen older 1950's homes with uninsulated walls, line-wire stucco and the single-glazed aluminum or steel sash windows. I recently inspected such a home that also had an old, marginal radiant heating system. They had also replaced all the windows with high-effeciency vinyl double-glazed units and then painted the home inside and out so that it would be more marketable and sell quickly. As a result of the new efficient windows, the original cold plane of the windows that used to cause major condensate buildup has been removed. The new windows no longer attract the condensate and it now builds up on the next-coldest plane... the drywall of the exterior wood-framed walls exposed on the interior. This in turn resulted in major mold buildup. How many of you have seen this type of unintended consequence, and do you warn your clients of the potential for excessive moisture buildup and resulting mold? What would your advice be for the homeowner that is now stuck with this condition?

Michael: How did you happen to post the Aquatech photos? Also, what do you mean by "unclear about the concept, part XXICVI" ? Were you aware that I had also worked on this very project, having been retained by the smaller building owner? This was just too wierd to see your reply and realize that it was a project that I had worked on. Let me know what you meant please. Thank you,

Thanks Kevin. I already have all of AAMA's information. Their tests aren't really designed for opening casement or single/double hung windows in a residence. I was specifically looking for a spec that speaks to how to test opening windows in residences after installation to confirm (or at least test) the manner in which they were installed/flashed and provide a level of confidence in their watertight integrity.

I am looking for a definative resource for water testing windows. I have the AAMA 502-02 spec and am more interested in the AAMA 501.2.3 spec with some actual info regarding what pressure should be applied and from what distance, etc. I have the necessary spray rig already and want to be able to test to a specific standard. Most of the AAMA standards indicate that the test protocols are not for residential windows that open. For those of you that are doing water testing or forensics, what standard are you using and can you post a copy of it or a link? Thanks,
