Concerned about rot and other moisture-related problems, builders searched for an answer."|
So my questions to you is; When you see an unheated crawl space with no venting or grossly inadequate venting by todays standards, but where a good vapor barrier is installed and where no moisture problems (WDO/WDI, standing water, effloresence, sediment stains, etc.) are visible, do you as a matter of course recommend that additional venting be installed? If so, even if the house is many decades old with no related problems to date?[/url]
