Had an undetected water leak from a cracked pipe that caused quite a bit of water damage to my bathroom. First Aid did a thorough job of inspecting the drywall for moisture and for mould that was developing which they found underneath the vanity cabinet.
A decontamination chamber was setup. The wet drywall was removed, the surfaces cleaned and sprayed with an antimicrobial.
Vadim was very knowledgeable and thorough so I was confident that the mould problem was resolved before the bathroom re-construction could start.
