Dean gets into fences, walls and hedges, discussing the differences between them and how to determine which one is right for your home and details the best preparation and installation for each of these options. Callers asked Dean's advice about low flow toilets, the proper paint to use in a kitchen, how to resolve a strange sewer smell coming from a largely unused bathroom and when putting in a post for a fence, is it better to use concrete or 'post hole foam.'
