How the leak is traced
According to a waterproofing contractor’s guide, a proper first visit by a contractor takes about 30-60 minutes and uses a moisture meter to map where the water spreads.
What to do first
Be wary of quotes given by phone without an inspection, according to the same guide.
Choosing a repair
Providers list options that range from no-hack methods, such as coatings and injection, to hacking up the tiles and redoing the waterproofing. The right one depends on the diagnosis, according to those providers.
