Q. As a handyman, one of the problems I see most often is rotted wood trim on windows and doors (for example, brick moldings, sills, and the bottoms of side jambs). Moldings are not usually a difficult fix, but repairing or replacing wood members that are integral to the window or door unit (particularly if it's a double window or a door unit with sidelights) is difficult without weakening the unit. Can you provide guidance about when to repair or replace the rotted wood and how to do it, or whether to simply replace the unit?
