Bathroom caulking and repairs in Vaughan usually involve stone or large format porcelain, because that is how Woodbridge, Maple and Kleinburg bathrooms were finished. Marble and travertine will not tolerate the wrong sealant, so the product matters as much as the workmanship here.
Frameless glass enclosures are the other constant. The bead where the glass meets the tile is on show from the doorway, so it has to be straight as well as watertight. I cut out the old, clean the surfaces, and lay a neutral cure bead that will not mark the stone.
