Richard helped a homeowner with a mysterious leak that caused a water stain on the foyer ceiling. First, Richard went to the upstairs bathroom and inspected the bathtub and toilet. He also looked at the floor tile and shower door. He then decided to open up the ceiling below to help determine the source of the leak. Using a reciprocating saw, Richard cut out a large, square piece of drywall just below the bathtub and toilet. With the ceiling opened up, Richard determined that neither the toilet nor bathtub drains were leaking. Back upstairs, Richard discovered that water was leaking around the shower door and down through the floor. To fix the problem, Richard installed a "door sweep" on the shower door to prevent water from escaping. He then removed some old tile grout around the base of the tub and applied a bead of silicone caulking, making a watertight seal. Finally, Richard replaced the ceiling drywall below and the repair was complete.
