Old galvanized supply line let go behind the kitchen wall of our 1928 Craftsman at 2 AM. Hardwood floors taking on water, lath-and-plaster ceiling below dripping. Called the line — actual tech picked up. Crew on-site in 35 minutes, extraction running by 3:15, controlled drying set up to save the quarter-sawn oak floor. Six days later the floor was at moisture spec, no cupping. They knew exactly how to handle the old house.
