Bathroom caulking and repairs in Ajax are often booked before anyone moves in. You get the keys to a Westney Heights or Nottingham house, walk into the bathroom, and the sealant around the tub is grey and peeling at the edges. That is a job worth doing before the first shower, not after.
I strip the old bead out completely, clean the surfaces, and lay a fresh one. Regrouting, loose tiles, a wobbly grab rail and a fan that has stopped working can all be handled on the same visit.
