Raised Garden Bed with Timbers; Clearing a Bathtub Drain

Ask This Old House – Season 4

Landscaping contractor Roger Cook helps a young couple build a raised garden bed using composite landscape timbers made from recycled plastic and sawdust. Back in the loft, Roger shows host Kevin O'Connor several other types of landscape timbers, including one that has been pressure-treated with liquid glass. Then, plumbing and heating expert Richard Trethewey helps a homeowner clear a slow-draining bathtub using a plumbing snake.
